Managing Myofascial Pain Syndrome: Breaking the Spasm Cycle

For individuals who have to be in one position for long periods, have poor postural alignment, and perform repetitive motions, what are myofascial pain syndrome spasm cycles?

Myofascial Pain Syndrome Spasm Cycles

Myofascial pain syndrome is a common condition that causes pain symptoms in a particular body area (Jafri M. S. 2014). A myofascial pain syndrome spasm cycle is a recurring pattern in which muscle tension and spasms in affected regions, caused by myofascial pain syndrome, lead to pain, triggering more muscle spasms. This creates a vicious cycle of discomfort and tightness that can be difficult to break without treatment; the pain perpetuates muscle spasms and vice versa.

Spasm Pain Cycle

Left untreated, myofascial pain is often experienced as a recurring cycle of spasm, pain, and spasm. (Kojidi M. M. et al., O2016) The exact cause of the spasm is not known. It may be related to excessive accumulation and release of acetylcholine, which causes sustained muscle contraction. (Nicol A, Crooks M, Hsu E, Ferrante M. 2018) Another theory is that repetitive small muscle trauma helps create a trigger point or knot in the muscle. (Thorne. 2021)

Active trigger points in muscles characterize myofascial pain syndrome. (Shah J. P. et al., 2015) These trigger points cause pain in the area where they are located and sometimes in other places, known as referred pain. Each muscle has a particular referral pattern of pain that goes from a trigger point in that muscle to another place in the body. (Shah J. P. et al., 2015) Medical providers and massage therapists trained in this area can identify trigger points by their pain patterns. With myofascial pain syndrome, muscles tense, and joint range of motion may decrease. (Jafri M. S. 2014)

Trigger Points

  • Myofascial pain syndrome is characterized by trigger points and sensitive knots within muscles that can cause referred pain when pressed, contributing to the spasm cycle.

Muscle Tension

  • A repeatedly tense or injured muscle can develop trigger points, which can lead tocle tightness and potential spasms.

Pain-Spasm-Pain Cycle

  • The pain from a trigger point can cause the muscle to further contract and spasm, leading to even more pain and perpetuating the cycle.

How Spasms and Pain Present

Myofascial pain is often caused by long periods of poor postural alignment, muscle injury, and repetitive motions. (Cleveland Clinic, 2023) For example, the upper body slumps forward when sitting at a desk workstation all day. The upper section of the trapezius muscle is located on the back of the neck and top of the shoulder. The upper trapezius muscle works to raise the head. (Yoo W. G. 2015) The trapezius muscle now has to work more than it is used to. This overuse may cause microscopic muscle injury, leading to muscle spasms and pain. (Bron C., & Dommerholt J. D. 2012) (Nicol A, Crooks M, Hsu E, Ferrante M. 2018) Without treatment, the muscle spasms, pain, and microscopic muscle injury may persist or worsen, leading to trigger points and chronic pain. (Jafri M. S. 2014)

Causes

Repetitive Motions

  • Repeating the same movement, like typing on a computer, can trigger muscle tension and points.

Poor Posture

  • Maintaining incorrect posture for extended periods can strain muscles and contribute to trigger point development.

Muscle Injury

  • Past injuries can leave muscles susceptible to developing trigger points and pain cycles.

Stress

  • Psychological stress can lead to muscle tension and exacerbate existing trigger points.

Break the Cycle

Physical Therapy

  • A physical therapist can use stretching, massage, and trigger point therapy to release muscle tension and address trigger points.

Exercise

  • Regular exercise, including gentle stretching, can help improve muscle flexibility and reduce tension.

Heat Therapy

  • Applying heat to affected areas can help relax muscles and alleviate pain.

Ergonomics

  • Modifying work habits and posture to reduce strain on muscles.

Stress Management

  • Techniques like deep breathing and meditation can help reduce stress-related muscle tension.

Mustard: A Low-Calorie Alternative Packed with Health Benefits

Can mustard be a low-calorie alternative to higher-fat condiments for individuals trying to reduce calorie intake?

Mustard

Prepared mustard is a common condiment used around the country. It is a low-calorie, highly flavored condiment that can replace more calorie-dense options. The familiar condiment combines mustard seeds with vinegar, salt, lemon, and other ingredients. There are also different varieties made from brown or black mustard seeds.

Health Benefits

Mustard is considered healthy because it contains antioxidants that provide various health benefits, including anti-cancer, antibacterial, antiviral, antifungal, anti-inflammatory, and wound-healing properties. (Mazumder A., Dwivedi A., & du Plessis J. 2016) Although not associated with significant health benefits, mustard is a low-calorie alternative to many higher-fat condiments, like mayonnaise. Different types of mustard seeds are used for health purposes. For example, some herbalists use white mustard seeds to clear the throat when mixed with honey (Ewing, Sarah, 1999). Antioxidants include isothiocyanates and sinigrin.

  • Isothiocyanates, the oil that gives mustard its pungent taste, have anti-cancer properties for breast, lung, GI tract, and prostate cancers.
  • However, the mechanism remains unclear, and more research is needed to determine the efficacy of mustard’s health benefits for cancer.
  • Isothiocyanates may also help manage diabetes and reduce unhealthy cholesterol, providing cardiovascular protection and neurological benefits that may help autistic individuals. More research is needed. (Palliyaguru D. et al., 2018)
  • Sinigrin is another antioxidant. Research shows this antioxidant has anti-cancer, antibacterial, antiviral, antifungal, anti-inflammatory, and wound-healing properties. (Mazumder A., Dwivedi A., & du Plessis J. 2016)

Nutrition

A single serving is usually about a teaspoon. A serving of prepared yellow and spicy mustard provides only about three calories. (U.S. Department of Agriculture, 2019) Its nutritional profile includes a rich supply of essential minerals, including calcium, iron, manganese, phosphorus, and zinc. It is also a good source of omega-3 fatty acids, tryptophan, phosphorus, iron, and protein. The seeds are also a very good source of selenium. Most calories come from carbohydrates, but because the calorie count is so low, these carbohydrates are not likely to significantly affect daily intake. Dijon mustard may provide more calories. A single serving of Dijon may contain up to 10 calories.

Preparation and Storage

Yellow mustard and Dijon are easy to find. Try course mustard varieties with distinct textures and seeds. Buy in small quantities, as mustard can lose flavor with time. Once opened, store in the refrigerator for up to one year. Mustard imparts a strong, spicy taste that pairs well with meat and seafood and can also be used to make salad dressings.

Side Effects

The U.S. Food and Drug Administration recognizes mustard as safe (GRAS). Eating too much can cause abdominal pain, diarrhea, and gut inflammation. However, mustard and mustard seed allergies are not uncommon. Symptoms may be mild or severe and generally appear shortly after consuming the product. Individuals may experience a rash or a tingly, itchy feeling in the mouth. Difficulty breathing is also possible. Other foods derived from the mustard plant, including leaves, seeds, and flowers, sprouted seeds, oil, and foods that contain these, are likely to cause reactions in those with mustard allergies.

Learn How to Perform Trapezius Self Massage for Pain Relief

Can individuals who sit for long hours daily prevent tight neck and shoulder muscles by improving their posture, regularly stretching, and massaging their trapezius muscles?

Trapezius Self Massage

The trapezius muscle is a triangle-shaped muscle in the upper back that starts at the base of the neck, spans the length of the upper shoulders, and extends into the middle back. This muscle’s main function is stabilizing and moving the scapula/shoulder blade. The trapezius also helps to move the head, neck, arms, shoulders, and torso, stabilizes the spine, and plays an important role in posture. Physical and mental stress can tighten the trapezius muscle, leading to neck and shoulder pain. Learning to perform a trapezius self-massage can ease tension and provide pain relief. (Domingo A. R. et al., 2017)

Anatomy

The trapezius consists of three parts in three different areas of the back. The bottom of the skull, across the shoulders, and down to the mid back. A trapezius self-massage focuses on the upper portion of the traps. This part is located at the top of the shoulders. To find the upper trapezius, cross one arm in front of your body so that you can place the palm on top of the other shoulder.

stock photo trapezius anatomy muscles isolated on white d illustration

For a trapezius self-massage, you need to know that there are two areas where your upper traps start and where the muscle connects to a bone. The first point is on the bottom of the skull, close to the center of the back of the skull. Start there with your fingers and trace the muscle down the back of the neck to where the shoulders widen. If you get lost, You can walk your fingers up or down the muscle on either side to relocate its origin at the base of the skull, the vertebra at the base of your neck that sticks out. This is C-7, another of the upper trapezius’s origin sites. (University of Washington Department of Radiology, 2025) 

Massage Technique

Massage oil is optional but can hydrate the skin during a massage. You can perform the trapezius self-massage using your hands.

Start at the Base of The Neck

Choose one shoulder to work at a time.

  • Raise the arm on the opposite side of your body.
  • Reach this arm across your body and fold it around your neck so that your fingers rest at the back base of your neck.
  • Apply a decent amount of pressure to the muscle while moving your fingers in a circular motion.
  • The action is similar to kneading dough.
  • Massage this area at the base of your neck for about 30 seconds to start.
  • If this part of your muscle is sore, you can massage it longer.

Slowly Work Out Towards The End of The Shoulder

Once you have spent about 30 seconds massaging the muscle at the base of the neck, work your way out toward the end of your shoulder.

  • In close increments, in your fingers across the trapezius muscle, spending at least 30 seconds at each point.
  • Follow the muscle until you reach the end of the shoulder.
  • Apply enough pressure, and use slow, rhythmic movements so that you feel relief.
  • If the pressure is not relieving or makes you wince, it’s too much.

Repeat as Needed

Repeat each side two to three times before switching to the other shoulder. After massaging, you may notice a certain trapezius area is particularly sore or tense. Zero in on those areas a little longer. Remember to relax throughout the trapezius self-massage. This is an opportunity to learn where tension is in your neck and shoulders and how to apply pressure to relieve it. This knowledge can also help you be mindful throughout your day, whether sitting, doing chores, or other physical activities. If you notice scrunching or slouching, massage the trapezius and remind yourself to keep your shoulders relaxed.

Benefits

Tension and tightness in the trapezius muscle are common, particularly among individuals who work in an office, do manual labor, or deal with a lot of stress. (Marker R. J. Campeau S., & Maluf K. S. 2017) Trapezius strains are a common overuse injury that is more likely to happen when the muscle is tight. (Salavati M. et al., 2017) The injury can cause unhealthy posture to avoid the pain. This poor posture will place more stress on the muscles, leading to a cycle of poor posture and chronic pain. A trapezius self-massage can benefit in many ways, including:

  • Improved blood circulation
  • Better quality of sleep
  • Improved posture
  • Improved range of motion
  • Decreased swelling
  • Faster recovery after workouts
  • Reduced risk of injury

Seeing a Healthcare Provider

Like any other muscle in the body, the trapezius can be injured and requires special treatment to recover. Sometimes, the neck or shoulder pain may not come from the trapezius muscle. Consider seeing a healthcare provider if you have pain in your neck or shoulder that doesn’t get better within a week or two, especially if it isn’t responding to at-home treatment. Regardless of how long you have been experiencing pain or stiffness, contact a healthcare provider if it prevents you from getting adequate sleep or interfering with daily activities. Reasons to see a healthcare provider immediately for neck or shoulder pain include: (Mount Sinai, 2025)

  • There is sudden pressure or pain in the left shoulder, which can sometimes signal a heart attack.
  • A fall or accident resulted in pain, swelling, or problems moving the neck or arm.
  • If there is shoulder pain, a fever, swelling, or redness.
  • The skin on the shoulder area appears discolored.

It’s important to take regular breaks to stretch and move your muscles. You can release tension in the trapezius by doing shoulder shrugs throughout the day and stretching regularly. When the trapezius feels tight or sore, give yourself a massage.

How Outcome Measurement Tests Can Guide Treatment

Can individuals experiencing difficulty with functional mobility benefit from physical therapy to help them return to normal activities?

Outcome Measurement Tests

Outcome measurement tests assess the effects of a treatment plan on a patient. They can be used to determine a patient’s baseline function, monitor their progress, and evaluate the effectiveness of treatment. They also give the therapy team an effective way to measure mobility, flexibility, and range of motion.

Function and Purpose

Outcome measurement tests serve various purposes. These include: (American Physical Therapy Association, N.D.)

  • To assist in goal-setting
  • Provide motivation
  • To guide treatment
  • To give a prognosis for the specific condition
  • To justify the treatment

The physical therapist may use other functional outcome measurements to help assess physical therapy progress.

  • They may measure your strength and range of motion.
  • Balance and posture may be evaluated.

Effective functional outcome measurement tests must meet certain criteria to be useful in a physical therapy clinic. First, they must be reliable, meaning the results must be consistent with each patient and within groups of patients. They must also be valid to measure exactly what they are intended to measure. An effective measurement test must also be easy to administer, so it must be practical and simple. Outcome measurement tests must also be purposeful. For example, a balance test must reflect a patient’s current function and be related to their balance ability.

Common Outcome Measurement Tests Used

Common functional outcome measurement tools that a physical therapist may use include:

  • The timed up-and-go or TUG test is a simple assessment used to evaluate a person’s mobility and balance by measuring how long it takes them to stand up from a chair, walk a short distance, turn around, walk back, and sit down again; it’s often used to identify potential fall risks in older adults, particularly those with mobility concerns, as a longer time to complete the task may indicate increased fall risk. (Centers for Disease Control and Prevention, 2017)
  • The Tinetti balance and gait evaluation, also known as the Performance-Oriented Mobility Assessment (POMA), is a clinical test used to assess balance and gait abilities, particularly in older adults. It evaluates stability during various standing and walking tests and provides a score that indicates a person’s fall risk potential.
  • The Berg Balance Scale (BBS) is a standardized test for adults that measures balance and the risk of falling. It’s widely used and can be performed in various settings.
  • The six-minute walk test (6MWT) is a medical assessment in which a person walks as far as they can in a designated area for exactly six minutes. This allows healthcare providers to evaluate their functional exercise capacity. It is particularly useful for assessing patients with lung or heart conditions where walking ability might be compromised. The distance covered during the six minutes is the key measurement used to interpret the test results. (Ferreira M. B. et al., 2022)
  • The functional reach test (FRT) is a clinical assessment that measures an individual’s dynamic balance by determining the maximum distance they can reach forward while standing in a fixed position. It assesses their risk of falling by evaluating how far they can extend their arm before losing stability. The FRT is often used to assess older adults or individuals with potential balance issues. 
  • The Oswestry low back pain disability questionnaire is a self-administered questionnaire used to measure the level of disability a person experiences due to low back pain. It assesses how the pain impacts their daily activities in various aspects of life, such as personal care, work, and social life; a higher score indicates greater disability. 
  • The functional independence measure (FIM) assesses a patient’s ability to perform daily activities independently. It also measures the patient’s disability level and how much assistance is needed.

Functional outcome measurement tests provide a starting point for developing physical therapy goals. For example, if the TUG test takes 19 seconds, individuals may aim for 10 seconds. A TUG score that falls at or over 10 seconds indicates reduced physical capacity (Kear B. M., Guck T. P., & McGaha A. L. 2017). This can be the motivation needed to reach physical therapy goals.

A Comprehensive Guide to Facet Arthropathy

Can individuals managing facet arthropathy treat the condition with over-the-counter pain relievers, prescription muscle relaxers, exercise, and chiropractic spinal manipulation?

Facet Arthropathy

Blog Image Facet Joint Arthritis

Facet arthropathy, or facet osteoarthritis, is arthritis that affects the facet joints in the spine. It causes pain and stiffness due to cartilage degeneration within these joints, often resulting from wear and tear associated with aging. Essentially, it occurs when the small joints in the back of the spine become arthritic and rub against each other painfully.

  • It affects the bony protrusions, called facet joints, that connect the spine’s bones.
  • Symptoms include neck and back pain that can worsen with standing, bending, or twisting.
  • Facet arthropathy is diagnosed using X-rays and other imaging studies.
  • Severe cases may require surgery.

Facet Joints

Twenty-four vertebrae form the spine, with two facet joints between each. Facet joints are small joints located at the back of each vertebra in the spine. They allow movement and stability, help maintain the alignment of the spinal bones/vertebrae, and limit excessive motion. The joints and the cushioning intervertebral disc form a three-joint complex between each vertebra.

  • The three-joint complex allows the spine to move, including bending, rotating, and extending.
  • Synovial fluid lubricates the joints so they can move.
  • The intervertebral disc provides flexibility and dissipates compressive loads.
  • The facet joints stabilize the spine by constraining rotation and bending.

Symptoms

Arthropathy refers to any disease affecting a joint, including arthritis. Osteoarthritis, also known as arthrosis, is a specific type of arthropathy. It is a non-inflammatory, degenerative arthritis. Pain is the main symptom that is typically worse in the morning when awakening, and in the evening, the pain can also get worse when twisting or bending backward. The symptoms can vary based on the part of the affected spine. Low back pain is the most common, a condition referred to as lumbar facet arthropathy because it affects the lumbar spine of the lower back. (Perolat R. et al., 2018) Common Symptoms include:

  • Muscle spasms or cramps.
  • Pain that may come in periodic flare-ups
  • Pain that worsens with standing or inactivity.
  • Dull pain on both sides of the spine.
  • Aching pain on both sides of the spine.
  • Pain in the lower back, buttocks, shoulders, or back of the skull
  • Radiating pain to the buttocks and legs.
  • Pain that improves with sitting, leaning forward, or changing positions.
  • Pins-and-needles sensations in the hands or feet.
  • Clicking sounds when moving the spine.
  • Catching sensations when moving the spine.
  • Muscle weakness.

Causes

Facet arthropathy causes progressive damage to the spine. Spinal osteoarthritis, aka spondylosis, is the most common cause, but it can also occur with a severe form of spinal arthritis known as ankylosing spondylitis. It is primarily due to age-related wear and tear, but injuries or repetitive stress on the spine can also cause it. Arthritis in the facet joints can develop due to:

  • Aging-related wear and tear
  • Disc problems
  • A previous back injury
  • Torn ligaments
  • Spinal fractures

Deterioration of facet joints can also cause bony overgrowths called osteophytes or bone spurs, which can cause radiating pain and restrict the spine’s range of motion.

Degeneration

  • The facet joints and intervertebral discs degenerate due to age-related wear and tear.
  • The cartilage in the facet joints can dry out, crack, and wear down.
  • The joint capsule and synovial membrane can inflame or tear, affecting synovial fluid production.
  • The loss of cartilage can lead to hypermobility, and the joint can stiffen over time.

Diagnosis

Imaging studies are important to the diagnosis. Several types confirm the diagnosis and also characterize the nature and severity of the condition:

  • X-rays provide a plain, black-and-white image of the spinal column.
  • CT scan composites multiple X-rays to create a three-dimensional image of the spinal column.
  • MRI uses magnetic and radio waves to generate images of soft tissues like ligaments and cartilage.

To confirm the diagnosis, a diagnostic block, which is a small amount of local anesthetic, is injected into a facet joint. The needle placement is directed either with an ultrasound or a CT scan. Facet arthroplasty is confirmed if the injection provides immediate relief (American Academy of Orthopaedic Surgeons, 2022). The healthcare provider will want to exclude other possible causes as part of the differential diagnosis. Conditions that mimic facet arthropathy include:

  • Herniated disc
  • Psoriatic arthritis
  • Reactive arthritis
  • Spinal gout
  • Spinal compression fracture

Treatment

The treatment varies based on its location and severity. Generally, conservative treatments are used before more invasive procedures are considered.

Lifestyle Changes

  • Initially, a healthcare provider may recommend rest and avoiding aggravating movements, including any activity that involves bending or twisting.
  • Activities that take the weight off the facet joint, such as sitting, leaning forward, or changing positions, may help ease the pain.
  • Patients may also be advised to adjust their sleep positions to take the pressure off facet joints.
  • Options included curling up on your side or lying on your back with the knees supported with pillows.

Medications

If a diagnostic block is used, a patient may not need medications immediately. However, as the anesthetic starts to wear off, the patient may be prescribed over-the-counter or prescription pain relievers based on the severity of the pain. These can include:

  • Analgesics like Tylenol
  • Nonsteroidal anti-inflammatory drugs like Advil or Aleve
  • Muscle relaxants like Lloresal for acute back pain
  • Antidepressants like Cymbalta for chronic back pain

Physical Therapy

Physical therapy is a major part of the treatment of lower back pain. The treatment plan will include personalized exercises to strengthen the core muscles and avoid stress on the spine. Examples include:

  • Mechanical traction and non-surgical to decompress the spine.
  • Knee-to-chest stretches, hugging your knees for 30 to 60 seconds.
  • Walking 10 to 20 minutes per day.
  • Aquatic therapy to alleviate pressure on the spine.

Surgery

If conservative measures don’t work or provide sufficient relief, a healthcare provider may recommend specialist procedures or surgeries that include:

  • Lumbar intra-articular injections deliver an anesthetic or corticosteroid into the spine for longer-lasting pain relief.

How to Properly Warm Up Before Running

Should individuals wanting to engage in the exercise start with a warm-up and end with a cooldown to prepare the muscles for optimal performance and post-workout recovery?

Warming Up, Cooling Down

Warming up 5 to 10 minutes before exercise is beneficial for pumping blood to the muscles and preparing them for a run. Dynamic or active stretching and light aerobic activity are a few ways to warm up. This could be active stretching, such as walking lunges, brisk walking, or riding a stationary bike for a few minutes before running. However, individuals should avoid static stretches before running, as they can increase the risk of injury. The minimum length of time for an effective cooldown session is five minutes. Depending on the intensity of the workout, individuals may choose to extend that to 10 minutes.

Steps for a Running Warmup

  • Do five to 10 minutes of light aerobic exercise to loosen up muscles.
  • Walk briskly, march, jog slowly, or cycle on a stationary bike.
  • Don’t rush.
  • Perform dynamic stretches and movements during the warmup, including walking lunges, jumping jacks, or toe touches.
  • Begin the run with a slow jog and gradually increase speed.
  • Slow down if you run out of breath.
  • This is part of knowing how fast you should run; starting too fast is a common mistake.
  • Pay attention to posture and form.
  • Ensure you are using the best technique before speeding up.

Warm Up Benefits

When warming up, the blood vessels dilate. The increased blood flow primes the muscles with oxygen and prepares them to perform at their best. Blood flow also increases the temperature in the muscles for enhanced flexibility. Allowing the heart rate to increase gradually is beneficial, instead of going full max heart output by jumping full speed into the running. (The American Heart Association, 2024)

Properly Cooling Down

At the end of the run:

  • Cool down by walking or slowly jogging for five to 10 minutes.
  • Breathing and heart rate should gradually return to normal.
  • Drink water or an electrolyte-infused drink to rehydrate the body.

Benefits of a Cooldown

The cool-down keeps blood flowing throughout the body at a consistent level. Stopping immediately can cause light-headedness because heart rate and blood pressure can drop rapidly. Winding down slowly allows heart rate and blood pressure to fall gradually. The cooldown is also a good mental transition from the intensity and accomplishing the workout.

Before or After Stretching 

Stretching evidence shows it doesn’t have the benefits once thought. Static stretching before, during, or after exercise has not been shown to prevent injury or delayed onset muscle soreness. (Herbert R. D., de Noronha M., & Kamper S. J. 2011) Stretching cold muscles is not recommended. However, there is some evidence that dynamic or active stretching after a warmup can benefit performance. Active stretching is done with exercises that take the muscles through their full range of motion and mimic the actions that will be done during the workout. (Van Hooren B., & Peake J. M. 2018)

Stretching After Running

Standard stretching includes the hamstring stretch, quad stretch, calf stretch, low lunge stretch, IT band stretch, butterfly stretch, hip and backstretch, arms and abs stretch, and triceps stretch. Tips for proper stretching:

Don’t Bounce

  • Avoid bouncing, as this mimics pulling a rubber band back and forth. You want the muscle to stay stretched.
  • Hold the stretch for 15 to 30 seconds.

Don’t Stretch Through Pain

  • Don’t stretch beyond the point where tightness is felt in the muscle.
  • Do not push through muscle resistance.
  • Never stretch to the point of pain.

Stretch Whole Body

  • Don’t just stretch the areas with tightness and/or soreness.
  • Stretch the whole body equally to prevent injury.

Don’t Hold Your Breath

  • Take deep breaths during the stretch.
  • Stay relaxed and breathe in and out slowly.

If starting a new fitness routine, consult your healthcare provider to determine the optimal running warmups and stretching exercises.

Exploring the Different Types of Knee Braces and Their Uses

Can a knee brace relieve discomfort, provide support, and expedite recovery for individuals recovering from an injury or surgery?

Knee Brace

A knee brace is a medical device that supports and stabilizes the knee joint to help with pain and recovery after an injury or surgery. Many knee braces are made of various materials and offer a range of support levels. A healthcare provider or physical therapist can recommend the appropriate one for your condition and suggest the best one. Ask a healthcare provider if you’re unsure, as wearing a knee brace correctly and for the recommended time is important for healing. They are generally safe. However, individuals with health conditions such as poor circulation should be cautious when using them and consult their healthcare provider.

What They Do

The knee joint comprises bones, cartilage, ligaments, tendons, and muscles. A knee brace stabilizes these structures, preventing them from moving too much or too fast. Some braces redistribute the knee joint’s weight, decreasing the force the knee absorbs. (American Academy of Family Physicians, 2020)

Conditions

A knee brace is used after surgery to aid in healing and following an injury. This can be:

  • Sprain
  • Ligament injury
  • Patellar/kneecap dislocation

They are also used to support the knee and relieve pain from some chronic conditions including: (Sprouse R. A., McLaughlin A. M., & Harris G. D. 2018)

  • Tendonitis
  • Patellar tendinopathy
  • Chondromalacia patellae
  • Patellofemoral stress syndrome
  • Medial knee osteoarthritis

Types

Knee braces differ in function and support level. Some stabilize the knee, while others completely immobilize the joint. A healthcare provider and/or physical therapist will explain what support is needed and how to use it. They can also check the brace’s fit and determine if adjustments or a different size are required.

Most Commonly Used

Prophylactic Brace

Unloader

  • This brace helps rebalance the weight and shift the pressure on the knee joint to other parts of the leg, reducing pain. (American Academy of Family Physicians, 2020)
  • A knee unloader is typically used to control discomfort due to inflammatory conditions like tendonitis and osteoarthritis.

Functional

  • This brace limits motion in the joint after an injury or prevents dislocation.

Bledsoe Brace

  • This brace has straps to wrap around the thigh and shin and support brackets on the inside and outside of the knee joint.
  • A small mechanism locks the knee into full extension or allows the knee to bend a specific amount.

Knee Immobilizer

  • A knee immobilizer keeps the knee in one position.
  • It is a long cloth brace that runs the length of the shin and thigh.

Knee Brace vs Knee Support

A knee support or sleeve is usually a tight-fitting fabric garment. It provides compression to help reduce swelling and discomfort. A knee brace offers more support and can also be set to limit mobility.

Wearing The Brace

Individuals may need to wear a knee brace all day or only when performing specific tasks and operations. It depends on the individual and the condition the brace is being used for. Some may only need to wear a knee brace during certain activities or a flare-up of pain. (Mayo Clinic, 2022) Wearing a brace for unnecessarily long periods can cause skin abrasion, joint stiffness, and muscle atrophy. (American Academy of Family Physicians, 2020) Conversely, neglecting to wear it can cause more susceptibility to injury or extend and or impair healing time. Ask a healthcare provider when you should and should not wear the brace. This could be when:

  • Sitting
  • Walking
  • Driving
  • Sleeping
  • Stretching

Contraindications

Some medical conditions can make an individual susceptible to injury and adverse effects from wearing a knee brace. These include: (Holden, M. A. et al., 2021)

  • Poor circulation
  • Superficial wounds on the knee
  • Psoriasis
  • Eczema
  • Arterial insufficiency
  • Severe varicose veins
  • A history of thrombophlebitis

If you have one of these conditions, a healthcare provider will decide if a knee brace is safe. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to build optimal health and wellness solutions. We focus on what works for you to relieve pain, restore function, prevent injury, and help mitigate issues through adjustments that help the body realign itself.

Muscle Relaxers for Back Spasms: What You Need to Know

For individuals who injure their neck or back, the muscles may spasm or seize up, making it difficult to get through the day, exercises, physical activities, etc. Can skeletal muscle relaxers help relieve pain and reduce frequency?

Back Spasms Muscle Relaxers

Back muscle spasms are common back pain that feels like a sudden tightness or contraction in the back muscles. They can range from minor twinges to severe pain.

Causes

  • Poor posture: Sitting or standing with bad posture can strain the back muscles.
  • Overuse: Picking something up, bending, or lifting can cause a spasm.
  • Dehydration: Not drinking enough water can cause electrolyte imbalances, leading to spasms.
  • Underlying conditions: A herniated disc or degenerative disc disease can cause back spasms.
  • Muscle imbalances: Weak muscles or muscles that are too tight can cause spasms.

Treatments

  • Home treatments: Apply heat or ice, take over-the-counter pain medication, try gentle stretching, or massage the area.
  • Exercise: Improve your back’s strength and flexibility with exercise or physical therapy.
  • Hydration and nutrition: Drink enough water and eat foods rich in magnesium and calcium.
  • Chiropractic Adjustments: These can realign the spine to the correct position and muscles to relax.
  • Non-surgical Decompression: Decompression of the spine will allow more blood and nutrients to heal painful areas.

Skeletal Muscle Relaxers

A healthcare provider may prescribe skeletal muscle relaxers. These medications are not available over the counter and must be prescribed by a healthcare provider.

  • Skeletal muscle relaxers will probably cause drowsiness.
  • Individuals should not drive, operate heavy machinery, or engage in other physical activities when taking back spasm muscle relaxers.
  • Skeletal muscle relaxers are not recommended for 65 or older because safer, effective alternatives exist.
  • Also, women who are pregnant or breastfeeding should not take these medications.
  • Discuss these issues with your healthcare provider.

Carisoprodol 

Carisoprodol is available generically and as Soma and Vanadom brands. It works by suppressing nerve impulses located in the brain and spinal cord. Healthcare providers prescribe this medication in combination with physical therapy for the healing release of any muscle spasm and management of musculoskeletal injuries and/or pain. (Witenko C. et al., 2014) It’s not about having to continue taking the medication to feel better but more as a jump start to help with the physical therapy program.

  • Back muscle spasms are a perfect example of a condition that may benefit from carisoprodol in the short term.
  • Carisoprodol can be habit-forming.
  • Be sure to talk to a healthcare provider before suddenly going off this medication.
  • Carisoprodol can cause side effects that may impair thinking or reactions.
  • Avoid drinking alcohol as it may increase drowsiness and dizziness that are often caused by carisoprodol. (Zacny J. P., Paice J. A., & Coalson D. W. 2012)
  • Inform your healthcare provider of any drug allergies, kidney disease, or liver disease, or if you get seizures.

Cyclobenzaprine

Cyclobenzaprine is available as Amrix and in generic form. Like other muscle relaxers, cyclobenzaprine may cause dizziness or drowsiness. The sedation effects are how it works on painful, tension-filled muscles. Cyclobenzaprine is used together with physical therapy to treat skeletal muscle-related conditions and/or injuries, especially when pain or spasm is involved. When used in conjunction with physical therapy, it can help expedite recovery.

  • Cyclobenzaprine is chemically related to tricyclic antidepressants.
  • Although it is considered a derivative of the tricyclic antidepressant class, it does not pose the same risk to liver health.
  • According to the National Institutes of Health, reasons not to take this medication include having a thyroid disorder, heart block, congestive heart failure, a heart rhythm disorder, or having recently had a heart attack. (Witenko C. et al., 2014)

Metaxalone

Skelaxin is the brand name for metaxalone. As with the other muscle relaxers, metaxalone is used in combination with physical therapy and rest when muscles get too tight. (Witenko C. et al., 2014) It works by suppressing nerve impulses in the brain and spinal cord. In addition to older individuals and pregnant women, metaxalone is usually not prescribed for those with kidney disease, liver disease, seizures, or blood disorders.

Healing with Needles: Acupuncture for Anxiety and Panic Disorders

Can acupuncture be an effective treatment for anxiety and panic disorders in addition to other treatments, like therapy and/or medication?

Acupuncture For Anxiety and Panic Disorders

Considered one of the most popular types of alternative medicine, acupuncture has grown in popularity as a way to treat a variety of mental health conditions, including depression, post-traumatic stress disorder (PTSD), and other anxiety disorders. With the growth in popularity, more research has been focused on treatment for panic and anxiety symptoms. (Pilkington K. 2010)

  • Acupuncture can enhance personal wellness.
  • Acupuncture is generally safe and has few side effects.
  • It can help reduce physical and mental symptoms like tension, pain, and rapid heart rate.

Other alternative medicine practices include yoga, therapeutic massage, herbal medicines, and aromatherapy.

Traditional Chinese Medicine

Acupuncture is a healing technique originating from traditional Chinese medicine (TCM). The practice is based on the concept that medical conditions and mental health disorders are caused by an imbalance in the energy and circulation of the body’s vital life energy, known as chi or qi (National Institute for Complementary and Integrative Health, 2022). When the body and mind function properly, energy flows optimally through the channels/meridians at certain points throughout the body. Like tight or spasming muscles, energy or circulation becomes congested in different meridian pathways, leading to disease or disorders. The goal of acupuncture is to restore the health and balance of these channels.

How It Works

During acupuncture treatment sessions, small needles are placed along specific body areas, known as acupuncture points. These areas are thought to be where energy blockage occurs. The needles, which come in various thicknesses and lengths, stimulate and open blocked energy channels. Experts have conceptualized acupuncture from a neuroscience perspective, where nerves, muscles, and connective tissues are stimulated, and neurochemicals are released.

  • Acupuncture can help regulate the nervous system.
  • It can stimulate the body’s feel-good hormones and reduce stress hormones.
  • It can help deactivate the analytical brain, which is responsible for anxiety and worries.

Acupuncture is recognized by the National Institutes of Health (NIH) for treating pain management and other medical conditions. (National Institute for Complementary and Integrative Health, 2022)

Effectiveness

Clinical trials examining acupuncture for anxiety and panic disorders have shown some positive results. (Pilkington K. 2010) Acupuncturists and medical professionals are still not clear exactly why it may help with anxiety, but some research has noted that acupuncture appears to have a calming effect. More research studies are needed to prove the effectiveness of acupuncture for anxiety disorders. (Kim Y. K. 2019)

Getting Treated

What it can help with:

  • Agoraphobia
  • Generalized anxiety disorder (GAD)
  • Panic disorder
  • Phobias
  • Selective mutism
  • Separation anxiety disorder
  • Social anxiety disorder

If you are interested in treating your anxiety and panic symptoms through acupuncture, the first step is to consult your main healthcare provider. Professional acupuncture practitioners are on websites, including the National Certification Commission for Acupuncture and Oriental Medicine and the American Academy of Medical Acupuncture. The use of acupuncture continues to rise, making it more readily available. Since it has been evaluated for effectiveness and is available through many hospitals, some insurance policies may cover some acupuncture treatments.

Exploring Nociceptors: Detecting and Reacting to Pain

Can understanding how nociceptors function and their role in processing pain signals help individuals who are managing injuries and/or living with chronic pain conditions?

Nociceptors

Nociceptors are nerve endings that detect harmful stimuli, such as extreme temperatures, pressure, and chemicals, and signal pain. They are the body’s first defense against potentially damaging environmental inputs.

  • Nociceptors are in the skin, muscles, joints, bones, internal organs, deep tissues, and cornea.
  • They detect harmful stimuli and convert them into electrical signals.
  • These signals are sent to the brain’s higher centers.
  • The brain interprets the signals as pain, which prompts the body to avoid the harmful stimulus.

Nociceptors, often called pain receptors, are free nerve endings all over the body. They play a pivotal role in how the body feels and reacts to pain. The main purpose of a nociceptor is to respond to damage to the body by transmitting signals to the spinal cord and brain. (Purves D, Augustine GJ, Fitzpatrick D, et al., editors. 2001) If you bang your foot, the nociceptors on the skin are activated, sending a signal to the brain via the peripheral nerves to the spinal cord. Pain resulting from any cause is transmitted this way. Pain signals are complex, carrying information about the stimuli’s location and intensity. This causes the brain to fully process the pain and send communication back to block further pain signals.

Classification

There are different classes of nociceptors, which are based on which type of stimuli they respond to (University of Texas McGovern Medical School, 2020)

Thermal

  • Thermal nociceptors respond to extreme hot or cold temperatures.
  • For instance, when touching a hot stove, the nociceptors, which signal pain, are activated immediately, sometimes before you know what you’ve done.

Mechanical

  • Mechanical nociceptors respond to intense stretching or strain, such as pulling a hamstring or straining a tendon.
  • The muscles or tendons are stretched beyond their ability, stimulating nociceptors and sending pain signals to the brain.

Chemical

  • Chemical nociceptors respond to chemicals released from tissue damage.
  • For example, prostaglandins and substance P or external chemicals like topical capsaicin pain creams.

Silent

  • Silent nociceptors must be first activated by tissue inflammation before responding to a mechanical, thermal, or chemical stimulus.
  • Most visceral nociceptors are located on organs in the body.

Polymodal

  • Polymodal nociceptors respond to mechanical, thermal, and chemical stimuli.

Mechano-thermal

  • Mechano-thermal nociceptors respond to mechanical and thermal stimuli.

Pain Transmission

Nociceptors are also classified by how fast they transmit pain signals. Transmission speed is determined by the type of nerve fiber known as an axon a nociceptor has. There are two main types.

  • The first type is A fiber axon, fibers surrounded by a fatty, protective sheath called myelin.
  • Myelin allows nerve signals/action potentials to travel rapidly.
  • The second type is C fiber axons, which are not surrounded by myelin and transmit slower. (University of Texas McGovern Medical School, 2020)

Because of the difference in transmission speed, the pain signals from the A fibers reach the spinal cord first. As a result, after an acute injury, an individual experiences pain in two phases, one from the A fibers and one from the C fibers. (Ngassapa D. N. 1996)

Pain Perception Phases

When an injury occurs, the stimulated nociceptors activate the A fibers, causing a person to experience sharp, prickling pain.

  1. This is the first phase of pain, known as fast pain, because it is not especially intense but comes right after the stimulus.
  2. During the second phase of pain, the C fibers are activated, causing an intense, burning pain that persists even after the stimulus has stopped.
  3. The fact that the C fibers carry burning pain explains why there is a short delay before feeling the sensation.
  4. The C fibers also carry aching, sore pain caused by organs within the body, such as a sore muscle or stomachache. (Ngassapa D. N. 1996)
