Center of Gravity Explained: A Comprehensive Guide

What is the body’s center of gravity to understand and maintain a healthy posture and balance?

Center of Gravity

The human center of gravity, or COG, also known as the center of mass, with the two terms being interchangeable, is where the body’s weight appears to be concentrated. It’s a point in space where the entire body’s mass can be concentrated. When standing upright, the COG is generally located behind the navel and in front of the sacrum, around the level of the second vertebra. (Le Huec, J. 2011) The center of gravity is related to posture, including issues such as swayback, the design of posture exercise programs, and much more.

  • Gravity is a downward pull or force the Earth exerts on the body, creating weight. (NASA, 2013)
  • The center of gravity (COG) is where a body’s weight is equally balanced in all directions. (Physiopedia, 2025)
  • When the COG is defined, it is done from the reference of a static, standing position.
  • Because the body is in motion when we change positions, the COG is located in a new position with each new position.
  • The center of gravity is the point around which all the parts balance, which may be inside or outside the body.
  • Even slight changes in position can change where the COG is. (Physiopedia, 2025)

Key aspects of the COG

Location

  • When standing upright, the COG is typically found at the second vertebral level, behind the navel and in front of the sacrum. (Le Huec, J. 2011)

Shifting COG

  • The COG can shift depending on body position, posture, and movements like bending forward or backward. (Physiopedia, 2025)

Balance Impact 

  • The relationship between the COG and the base of support (the area of the body in contact with the ground) is fundamental to maintaining balance.

Variations

  • There can be variations in the COG location based on factors like gender (men tend to have a slightly higher COG), body shape, and even conditions like obesity or chronic low back pain. (Physiopedia, 2025)

Biomechanics

  • Understanding the COG is crucial in biomechanics and movement analysis, as it’s an index of total body motion and how the body responds to external forces.

The Human Center

The center of gravity is the point at which the body’s mass is equally balanced. This point changes depending on one’s position:

  • Arms up/down
  • Leaning
  • Turning

With strength and flexibility training, the human body can change its center of gravity, as gymnasts and dancers do.

  • When standing, the center of gravity is normally located behind the navel and in front of the sacrum bone (made up of five vertebrae fused vertically) at about the second vertebra level. (Hasegawa K. et al., 2022)
  • Because the body has moving parts, its overall shape changes every time it moves. Carrying something like a suitcase or grocery bag or wearing a backpack adds weight to some areas but not others, changing the center of gravity as it does.
  • The center of gravity is a continually changing point inside or outside the body that represents where the weight or mass of the rest of the body is equally balanced in every direction.
  • This point can and does change based on what is being carried and how it is carried, as well as body position and movements.

Chronic Lower Back Pain

  • A study in the Journal of Back and Musculoskeletal Rehabilitation found that individuals with chronic lower back pain tend to have their center of gravity located excessively towards the back. (Kim D. H., Park J. K., & Jeong M. K. 2014)
  • In the study, the individuals had decreased low back strength upon extension and a reduced normal low back curve.
  • The researchers found that those with chronic lower back pain whose center of gravity was too far back may need physical therapy to retrain the body to overcome strength and balance challenges to re-establish and maintain a healthy posture.

Paraspinal Muscle Tension: Understanding the Impacts

Can a paraspinal muscle spasm in the lower back create a chain reaction leading to hamstring spasms and potential sciatic nerve entrapment?

Paraspinal Muscle Spasm Chain Reaction

A paraspinal muscle spasm in the lower back can cause a cascade of events, including: (Cedars-Sinai, 2025)

  • Spasms in other lower back muscles
  • Hamstring spasms
  • Potential entrapment of the sciatic nerve

Leading to symptoms similar to sciatica: 

  • Pain
  • Sore, achy muscles
  • Weak muscles
  • Numbness
  • Tingling along the back of the leg

Possible Mechanisms

Triggering Muscle Spasms in the Lower Back

  • Paraspinal muscles are located along the spine and help to stabilize and support the lower back.
  • When these muscles spasm, they can become tense and painful, causing a chain reaction.
  • This tension can radiate down and affect other muscles in the lower back. (Noonan A. M., & Brown S. H. M., 2021)

Can Affect Lower Back Muscles and Cause Hamstring Spasms

  • Lower back muscles, including those like the quadratus lumborum, can be affected by paraspinal spasms. (Hospital for Special Surgery, 2024)
  • The spasms can cause these muscles to tighten or spasm, potentially pulling on the hamstring muscles.
  • This can lead to hamstring spasms and tightness, further contributing to pain and potential nerve irritation.

Entrapment of the Sciatic Nerve

  • Piriformis syndrome is a common condition where the piriformis muscle (located in the buttock) spasms and compresses the sciatic nerve. (Cedars-Sinai, 2025)
  • The sciatic nerve runs from the lower back down the back of the thigh and into the leg, making it vulnerable to compression by surrounding muscles.
  • If the paraspinal and hamstring spasms create enough tension on the piriformis muscle or surrounding tissues, it can lead to sciatic nerve entrapment. (Hospital for Special Surgery, 2024)

How acupuncture helps relieve sciatica

Acupuncture can help relieve sciatica pain by stimulating specific points on the body, which can trigger the release of endorphins, reduce inflammation, improve blood flow, and relax tight muscles that could be compressing the sciatic nerve. By modulating the nervous system and promoting the body’s natural healing processes, acupuncture can help alleviate pain and improve overall function. (Qin, Z. et al., 2015)

Releases endorphins

  • Acupuncture stimulates the nervous system, triggering the release of endorphins, the body’s natural painkillers.

Reduces inflammation

  • Acupuncture can help reduce inflammation in the area surrounding the sciatic nerve, which can contribute to pain and nerve irritation. (Natural Care Chiropractic, 2022)

Improves circulation

  • By increasing blood flow to the affected area, acupuncture can help deliver nutrients and oxygen to the sciatic nerve and surrounding tissues, promoting faster healing.

Relaxes tight muscles

  • Sciatica pain can be exacerbated by tight muscles compressing the nerve. Acupuncture can help relax these muscles, reducing pressure on the sciatic nerve and alleviating pain.

Regulates the nervous system

  • Acupuncture can help regulate the nervous system, positively impacting pain perception and overall well-being. (Qin, Z. et al., 2015)

Promotes regeneration

  • Some evidence suggests that acupuncture can promote sciatic nerve regeneration, potentially leading to long-term pain relief. (Natural Care Chiropractic, 2022)

Needling Types

Distal needling

  • Acupuncture can also involve using points that are further away from the site of pain, which can also help to reduce pain and inflammation. 

Local needling

  • Points are also selected on or near the sciatic nerve’s path, which can help directly address the source of pain and inflammation. (Qin, Z. et al., 2015)

Holistic approach

  • Acupuncture is often viewed as a holistic approach to pain management, addressing the symptoms of sciatica and the underlying causes and imbalances in the body.

Pseudoarthrosis After Spinal Fusion Surgery Explained

What is pseudoarthrosis of the cervical and lumbar spine?

Pseudoarthrosis of the cervical and lumbar spine

Individuals may need a spinal fusion to treat a fractured vertebra, scoliosis, or conditions like spinal stenosis, degenerative disc disease, and spondylolisthesis/slipped vertebrae. A spinal fusion reduces pain and stabilizes the spine by limiting movement between vertebrae. Pseudoarthrosis happens when the bones don’t heal after a fracture or bone surgery. When pseudoarthrosis affects the cervical or lumbar spine, it means that two vertebrae did not heal and grow together after spinal surgery to fuse them (spinal fusion). Reasons for a failed spinal fusion include:

  • Issues with the instruments used to stabilize the bone
  • Lack of bone growth
  • The number of vertebrae being fused.

The patient’s health and lifestyle play a role in failed fusions, which can include

  • Diabetes
  • Inflammatory health conditions increase the risk
  • Smoking
  • Long-term steroid use

In many cases, revision surgery is needed.

Surgery-Related

During a spinal fusion, surgeons insert a bone graft between two vertebrae and then apply spinal fixation hardware (instrumented spinal fusion) that includes:

  • Plates
  • Rods
  • Screws
  1. The bone graft promotes growth between the two bones.
  2. The hardware stabilizes the vertebrae and prevents movement while they fuse and grow together.
  3. The hardware goes inside, or internal fixation.
  4. Although rare, a severe spinal fracture or deformity may need external fixation.
  5. A rigid frame secured outside the body helps to stabilize the bones.

If the fusion fails, it could be caused by one or more of the following surgical issues:

Number of Vertebrae Being Fused

Hardware

  • The surgeon must carefully plan and use the right hardware.
  • The type of hardware used during a spinal fusion may influence bone healing.
  • The instruments can come loose or break, interfering with the fusion process.
  • Spinal osteoporosis, having thin, weak bones, can affect fixation.
  • Even with the optimal surgical preparedness, weak bones significantly increase the chance of the instruments loosening and pseudoarthrosis developing.

Bone Graft

  • The type of bone graft used may affect the fusion.
  • For example, in cervical/neck spinal fusions, an autograft, which uses a small piece of bone from the patient’s body, has a higher success rate. (Verla T. et al., 2021)
  • Other graft options include specialized steel cages that fit between vertebrae and contain bone growth factors.
  • The surgeon recommends the optimal bone graft for the type of surgery, the number of vertebrae involved, and risk factors.

Risk Factors

  • The patient’s overall health and lifestyle impact the results of spinal fusion. Smoking increases the risk. (Berman D. et al., 2017)
  • Nicotine restricts blood circulation, decreases bone density, reduces new bone formation, and delays bone healing. (Hernigou J., & Schuind F., 2019)

The risk of pseudoarthrosis increases if the individual has any of the following: (Scoliosis Research Society, 2023)

  • Previous pseudoarthrosis
  • Obesity
  • Chronic steroid use
  • Malnutrition
  • Inflammatory diseases

Inflammatory conditions that can lead to bone loss and non-optimal bone healing include: (Torres H. M. et al., 2023)

  • Diabetes (Jiao H, Xiao E, & Graves DT, 2015)
  • Inflammatory bowel disease
  • Psoriasis
  • Rheumatoid arthritis
  • Chronic obstructive pulmonary disease/COPD
  • Periodontitis
  • Systemic lupus erythematosus/SLE

Symptoms

  • The primary sign of pseudoarthrosis is pain in the same area as before the fusion surgery.
  • If the bones pinch a spinal nerve, one arm may experience pain, tingling, burning, or numbness.
  • Rarely does a pinched nerve affect both arms.
  • The pain may return shortly after the procedure.
  • The pain may develop gradually or not appear for many months.
  • However, it’s more likely to appear after several months when the individual returns to their usual activities.

Diagnosis

  • The healthcare provider will learn about symptoms and perform a physical exam to evaluate the back.
  • They’ll assess mobility and the type of movement that causes pain.
  • Then, they order diagnostic imaging to see the spine and identify the cause of pain.
  • Individuals may need a CT scan, MRI, and/or X-rays to evaluate the spinal structures and instrumentation fully.

Treatment

Treatment for pseudoarthrosis will likely start with:

  • Physical therapy
  • Pain management – especially in cases where it is important to rule out other sources of back or neck pain.
  • Medication
  • Injections
  • If symptoms don’t improve with conservative care or if there is severe pain, the healthcare provider may recommend revision surgery.
  • Revision surgery is another procedure to treat complications or correct issues that arise after the initial pseudoarthrosis surgery.

Length of Time for Muscle Tightness Relief

For individuals dealing with or experiencing muscle pain and stiffness, how long does it take to loosen tight muscles?

Length Of Time to Loosen Tight Muscles

Tight muscles are often caused by overuse or strain, combined with muscle soreness, a common symptom of tight muscles. The soreness peaks around the third day and begins to subside, typically resolving within a few days. But if tightness persists or is accompanied by other symptoms like numbness, inability to move, or swelling, it’s important to consult a medical provider. (Spine Medicine and Surgery of Long Island, 2024) However, it can take much longer for individuals who have never stretched and have had tight muscles for years, depending on the severity, injury history, and underlying causes.

Factors Influencing Timeline

Consistent stretching can take anywhere from a few weeks to a few months to noticeably loosen tight muscles and improve flexibility. The specific time frame depends on factors like the severity of the tightness, underlying causes, and individual consistency with stretching. (Peterson Physical Therapy, 2024)

Severity of Tightness

  • Muscle knots and significant limitations in range of motion may take longer to resolve than minor stiffness.

Underlying Causes

  • If tightness is due to a specific injury or condition, addressing that cause is important for lasting and maintaining improvements. (Healthline, 2023)

Individual Factors

  • Genetics, age, and overall health can influence how quickly muscles adapt to stretching.

Consistency

  • Regular stretching, ideally daily or several times a week, is essential for feeling progress. (Mayo Clinic, 2023)

Stretching Routine

The length of time can vary based on the starting flexibility level and the specific stretching routine. (Mayo Clinic, 2023) It typically takes several weeks of consistent stretching, at least 3-4 times a week, to notice flexibility improvements. Longer-term changes, beyond the initial feeling of being looser, usually take 8 to 12 weeks.

Consistency

Hold Time

  • Hold static stretches for at least 30 seconds.
  • Longer holds (1-2 minutes) can provide deeper benefits.

Long-term Gains

  • For substantial and sustained improvements, stretching consistently for several months is recommended. (Mayo Clinic, 2023)

Initial Changes

  • Individuals may notice small improvements in the first few weeks, especially starting from a more inflexible position.

Influencing Factors and Results

  • Individual genetics, current flexibility level, and the specific exercises can affect how quickly improvements are seen and felt. (Peterson Physical Therapy, 2024)

What To Expect

Improvements

  • Within a few weeks, individuals might notice a decrease in the sensation of tightness or increased ease in reaching a stretch. (Peterson Physical Therapy, 2024)

Longer-Term Changes

  • Significant muscle length and flexibility improvements may take several weeks to months of consistent effort.

Maintenance

Treatment Options

  • Stretching, physical therapy, massage, and other therapies can help alleviate tight muscles and promote recovery. (Spine Medicine and Surgery of Long Island, 2024)
  • Consider professional guidance for specific concerns or limitations. Consult a physical therapist or healthcare provider for personalized recommendations.

The length of time to see results means consistency and patience are important.

Pilates Nutrition for Enhanced Performance and Recovery

Many ask, what and when should you eat before, during, and after engaging in Pilates exercises?

Pilates Nutrition Plan

Pilates involves a lot of core work on the mat. However, it does not require a special diet. To fully utilize Pilates nutrition, individuals should consider what foods keep their bodies feeling the most balanced. A balanced nutrition plan can enhance Pilates practice by:

  • Providing sustained energy
  • Supporting muscle recovery
  • Promoting overall well-being

Pre-Pilates

Timing

  • Eat a light meal or snack 2-3 hours before a class or a smaller snack 30 minutes before.

Food Options

  • Eat complex carbohydrates like whole grains, fruits, and vegetables for sustained energy.

Avoid

  • Heavy, greasy, or spicy foods may cause discomfort during exercise.
  • Foods that will make you gassy or cause queasiness.

During the Workout

Complex carbohydrates and lean proteins, with a little healthy fat, are good pre-Pilates meals, as they sustain energy better than simple carbs or sugary snacks. (American Heart Association, 2024) Suggestions for a pre-Pilates meal.

  • Individuals can adjust the portion size.
  • A protein shake that uses fruit can be convenient.
  • Peanut butter on whole-grain bread offers a quick source of complex carbohydrates and protein.
  • Yogurt with fruit.
  • Small portion of oatmeal.

Because Pilates emphasizes using the abdominal muscles, individuals will want to ensure that any food they’ve eaten before their session is fully digested. Try to eat light before, like snacking on a banana or sipping on a smoothie for some carbohydrates for energy. Regardless of what is eaten, nutrition experts recommend waiting two to three hours after eating before exercising.

Maintain Hydration

  • Drink water and/or eat hydrating fruits throughout the day, especially before and during the workout or class.

After Working Out

Individuals want to ensure their bodies have enough nutrients to strengthen their muscles and replenish their energy. Try a protein green smoothie afterward or a light snack with lean protein like fish or chicken and carbohydrates like whole grains. The diet between workouts will depend on weight loss goals.

Timing

  • Consume a protein-rich snack or meal within 30-60 minutes after your class to aid muscle recovery.

Food Choices

  • Focus on protein for muscle repair and carbohydrates to replenish energy stores.

Hydration

  • Continue to hydrate to replenish fluids lost through perspiration.

While Pilates can complement cardiovascular exercise as part of a fat-burning workout program, health experts advise that losing weight will not come from exercise alone. Individuals will need to work on reducing their calorie intake overall. (Centers for Disease Control and Prevention, 2023)

Running Fartlek Training for All Skill Levels

Can adding fartlek training improve speed and endurance for runners and running enthusiasts?

Running Fartlek Training

Fartlek training, which means speed play in Swedish, is a form of running training that involves alternating between bursts of fast running and slower recovery jogging.

  • It is a form of interval or speed conditioning.
  • It involves varying one’s pace throughout their run, alternating between fast treks and slow jogs.
  • Workouts are unstructured and allow runners to decide the duration and intensity of the fast and slow sections.
  • Unlike formal interval training, this flexibility offers a new way to improve speed, endurance, mental preparedness, and stamina.

Training Benefits

Traditional interval training uses specific timed or measured segments. Fartleks are more unstructured, with work-rest intervals based on how the body feels. With fartlek training, individuals can experiment with pace and endurance as they run, which helps them tune in to their body and adjust how it performs. Many runners enjoy the training because it involves speed work and is more flexible and less demanding.

  • A stopwatch is not needed for time intervals.
  • Training doesn’t have to be done on a track and can be performed on all terrain, such as roads, trails, or hills.
  • The training stresses the body’s systems, leading to faster speeds and improving anaerobic threshold. (Bacon, A. P. et al., 2013)
  • Improves the anaerobic threshold and increases the body’s ability to train longer at higher intensities. (Mazurek K. et al., 2016)
  • This is due to an increased VO2 max, which measures how much oxygen the body can take in and use.
  • A better VO2 Max generally leads to improved performance. (Scribbans T. D. et al., 2016)

Disadvantages

  • Training includes a higher risk of injury and strain.
  • Beginners are more prone to shin splints.
  • The training is demanding, so it should not be done daily.

Workout

The method is to vary brief periods of slightly higher pace into regular runs (Kumar P. 2015). Maintain a faster pace for a short distance or time interval, such as 200 meters or 30 seconds. Intervals can vary throughout the workout, and landmarks such as streetlights or telephone poles can be used to mark segments instead of measuring miles or meters. Once a fast segment is completed, slow to below-normal running cadence until the body fully recovers and breathing returns to normal. Return to running normally and incorporate slightly faster intervals later in the run.

  • Fartleks should be short because they are intense.
  • The actual higher-pace portion of the run should last up to 30 seconds.
  • Gradually add more time to the faster-paced portion as conditioning improves, up to 60 seconds.

Training Example

An example of a 40- to 45-minute fartlek workout suitable for beginners.

  • 10-minute warm-up at a light pace
  • 1 minute on (fast pace)
  • 2 minutes off (easy)
  • 2 minutes on
  • 1 minute off
  • Repeat the set 3 to 4 times
  • 10-minute cooldown at an easy pace

Remember that beginners should go slow when introducing fartlek training into their workouts. It is more intense and can increase the risk of injuries and strains, such as shin splints. Get help from a running coach or trainer if you are unsure how to incorporate the training into your routine.

Training on a Treadmill

Speed play can be done on a treadmill. The idea is to find ways to create speed variation intervals and help relieve treadmill boredom. Some examples include:

  • If watching television, use commercials to go into speed intervals.
  • At the gym, make a game out of the sprints and/or
  • Speed up during certain parts of songs where you can feel the energy moving you faster.

One precaution is learning to use the treadmill’s buttons to increase and decrease the pace. This can slow you down and disrupt form, so maybe do longer durations for each phase so there is less contact with the control panel.

Postural Assessment for Optimal Movement Efficiency

Can postural assessments help identify problems with how a person stands or sits, which can lead to various musculoskeletal issues?

Postural Assessment

Proper posture is an exercise in which the muscles support the skeleton in a comfortable, stable, and efficient alignment. Healthy posture is present when the body is still and when moving. However, numerous factors can affect and hinder posture. These include daily wear and tear, injury, illness, or a condition. A posture assessment is a process that identifies posture issues and their root causes, often using visual and palpation techniques, and can help determine appropriate treatment or exercises. (Science Direct, 2007)

Visual Assessment

  • Observing the body’s alignment and symmetry from different angles (anterior, posterior, and lateral views).

Palpation

Movement Analysis

  • Assessing how a person moves and if there are any limitations or compensations. (Physiopedia, 2025)

Importance and Benefits

Early Identification

  • Helps identify potential problems early, before they become more serious.

Targeted Treatment

  • Allows for the development of personalized treatment plans to address specific postural issues.

Injury Prevention

  • It can help prevent injuries by addressing underlying postural imbalances.

Postural Assessment Tools

Some tools used include:

Basic Assessment

Stand Upright

  • The patient stands with their feet shoulder-width apart, arms relaxed at their sides, and looks straight ahead. (Science Direct, 2007)

Alignment Observation

  • Head: Is the head aligned over the shoulders, forward, or tilted?
  • Shoulders: Are the shoulders level, or are they rounded forward?
  • Back: Is the back straight, or is there excessive curvature (kyphosis or lordosis)?
  • Pelvis: Is the pelvis level or tilted forward or backward?
  • Knees: Are the knees straight or slightly bent?
  • Feet: Are the feet flat on the ground, or is there excessive arch or pronation?

Palpate for Muscle Imbalances

Consider the Patient’s Activity Level and History

Wall Test

  • The patient stands against a wall with their feet shoulder-width apart and heels about 6 inches from the baseboard.
  • If they have good posture, their ears will be vertically aligned with their shoulders, and their head will be no more than three finger widths from the wall. (Physiopedia, 2025)

Postural Issues Examples

Rounded Shoulders (Hyperkyphosis)

  • Forward rounding of the upper back.

Forward Head Posture

  • Head positioned too far forward.

Lordosis

  • Excessive inward curve of the lower back.

Flat Back

  • Reduced natural curve of the lower back.

Muscle Imbalances

Professionals Who Can Perform a Posture Assessment

Physiotherapists

  • Professionals trained in assessing and treating musculoskeletal problems.

Chiropractors

  • Professionals who focus on the spine and nervous system.

Fitness Professionals

  • Personal trainers or other fitness professionals can use posture assessments to help clients improve their posture and movement.

Ergonomists

  • Professionals who specialize in designing workspaces and environments to promote good posture and reduce strain.

Post Surgery Leg Strengthening Tips for Patients

What are some leg-strengthening exercises that will expedite recovery for athletes and physically active individuals who have undergone leg surgery?

Post Surgery Leg Strengthening

Leg muscles may weaken after hip, knee, ankle, or foot surgery. This happens because those muscles are not used as much during recovery. Gaining back strength and muscle endurance after an injury or surgery is an important step in recovery. Leg exercises can help regain mobility and prevent complications like blood clots and pressure sores after surgery or an injury, which is why engaging in post-surgery leg strengthening is important once the doctor gives the ok.

Benefits

post-surgery leg strengthening exercises have several benefits, including

  • Rebuilds strength and confidence
  • Retraining for optimal mobility and flexibility
  • Prevents pressure sores
  • Prevents blood clots

When the leg muscles are contracted, they move blood like a pump, maintaining proper circulation. Moving in a bed after surgery also helps prevent pressure sores from forming and blood clots. A physical therapy team will determine the right leg exercises for each individual and their injury/condition. This is an important step when moving forward after surgery. (Hoogeboom T. J. et al., 2014)

Starting Out

The first exercises should target all the major muscles of the leg. (Madara K. C. et al., 2019)

Gluteal Sets

This isometric exercise means the muscles contract while no motion occurs at the hip joints. To perform:

  • Lie on your back and tighten your buttock muscles.
  • Hold the muscles tight for 5 seconds, then relax.
  • Repeat 10 or 15 times.
  • Gluteal sets can be done several times per day.

Heel Slide

Heel slides can help regain strength in the major muscles of the leg. To perform:

  • Lie on your back.
  • Bend the knee of the surgical leg and slowly slide the heel toward your butt.
  • Slide as far as possible and hold for 5 seconds.
  • Slowly return to the starting position and repeat.

Short Arc Quad

The short arc quad, or SAQ, is a simple way to get the quadricep muscles working. To perform:

  • Lie on your back with a towel roll, small ball, or something similar under the knee.
  • Slowly straighten the knee.
  • Tighten the quad muscle on the top of the thigh.
  • Hold for 3 seconds, then relax.
  • Repeat 10 to 15 times.

Quad Set

This exercise helps get the quad muscles working. It also helps control the position of the kneecap. To perform:

  • Lie on your back.
  • Place a small towel roll under the knee.
  • Try to press the back of the knee flat against the floor.
  • Hold for 10 seconds and release.
  • Repeat 10 to 15 times.

Individuals can complete quad sets bilaterally or with both knees simultaneously. This makes the stronger leg help strengthen the weaker side.

Straight Leg Raise

To perform:

  • Lie on your back.
  • Lift your leg straight off the floor until it is at the height of the opposite bent knee.
  • Hold for 10 seconds and slowly lower.
  • Repeat 10 to 15 times.

Be sure to keep the knee straight for the entire exercise. Keep the opposite knee bent for comfort. To ensure the knee is straight, individuals can complete a quad set first and then the straight leg raise. The exercise can be more challenging by increasing repetitions or adding a 2- to 3-pound ankle weight on the thigh. For even more challenge, add the ankle weight to the ankle.

Hamstring Strengthening

Working out the hamstrings after injury or surgery is important. The hamstring muscles bend the knee and extend the hip backward. To perform:

  • Lie on your stomach.
  • Bend one knee to raise the lower limb straight in the air.
  • Hold for 5 seconds and lower slowly.
  • Repeat 10 to 15 times.

Once the exercise is easy to do, increase the repetitions to 30. Individuals can also try adding a 2- to 3-pound ankle weight.

Physical therapy can help individuals regain mobility after injury or surgery. A therapist may prescribe exercises as part of an at-home exercise program. Over time progress will go from simple exercises to more challenging ones to improve balance and mobility. (Madara K. C. et al., 2019)

Lidocaine Patch for Pain Relief: An Overview

For individuals experiencing lower back pain and sciatica symptoms, can using a lidocaine patch help?

Lidocaine Patch

Lidocaine patches are in a drug class called local anesthetics (MedlinePlus, 2025) (Food and Drug Administration, 2022). They relieve pain in small body areas by blocking the nerves from sending pain signals. The Food and Drug Administration approved lidocaine 5% or 1.8% patches for relieving postherpetic neuralgia (PHN) pain. These lidocaine patches are prescription-only (Food and Drug Administration, 2022). They are available either by prescription or over the counter and are commonly used for back pain and other areas. Over-the-counter lidocaine, 4% patches, can be used to relieve minor aches and pains, including back pain. However, further research is needed to recommend the use of lidocaine patches as an effective method of pain relief. (Department of Veterans Affairs/Department of Defense, 2022) (North American Spine Society, 2020)

The Patch

They are available in prescription and over-the-counter forms. Over-the-counter forms come as a 4% patch in various brands, such as (MedlinePlus, 2025)

  • Aspercreme
  • Lidocare
  • Salonpas

Prescription-only patches come in 5% or 1.8% patches and are approved to relieve long-term nerve pain from shingles in adults. Zlido is a brand name for a 1.8% lidocaine patch. Five percent lidocaine patches are available generically. (DailyMed, 2018) (Food and Drug Administration, 2021) The safety and effectiveness in children are unknown. (Food and Drug Administration, 2022)

Other Lidocaine Forms

As a local anesthetic, it is available in several other forms, including:

  • Spray
  • Topical cream
  • Lotion
  • Liquid
  • Ear drops
  • Eye gel
  • Injection
  • It is also available as a short-term intravenous infusion for abnormal heart rhythm. (DailyMed, 2025)

Effectiveness

Clinical trials have shown that the patches effectively relieve chronic low back pain. However, these studies were nonrandomized and did not include a control group to compare against the treatment group. (Santana J. A., Klass S., & Felix E. R. 2020) The results may be subject to potential biases. For this reason, further evidence is needed to support lidocaine patches’ effectiveness in reducing low back pain. (North American Spine Society, 2020) High-quality randomized and controlled clinical trials are necessary to study the effectiveness. (North American Spine Society, 2020) (Santana J. A., Klass S., & Felix E. R. 2020)

How to Use Safely

In general, keep the following in mind (MedlinePlus, 2025)

  • Use according to the directions on the box and the healthcare provider’s recommendations.
  • Do not use on broken or inflamed, swollen skin.
  • Do not apply heat like heating pads or electric blankets over patches.
  • Avoid getting water on or around the patch.
  • Avoid letting a patch near your eyes to limit eye irritation.
  • Fold the sticky sides of the used lidocaine patches together and safely throw them away, keeping them away from children and pets.

How to use (MedlinePlus, 2025)

  • Clean and dry the affected area before placing the patch.
  • Apply to the affected body area as directed.
  • Wash your hands after touching the patch.
  • Remove the patch after what is usually recommended after eight hours.

How Quickly Does It Work?

The amount of medication absorbed into the blood depends on how long the patch is placed on the body and how much is covered with the patch. In a study, healthy participants wore three lidocaine patches on their backs for 12 hours on and 12 hours off during 24 hours. Lidocaine levels were highest at 11 hours. At the end of the 24 hours, there was still some lidocaine left in the bloodstream. (Food and Drug Administration, 2022)

Individuals with PHN may notice a difference in pain intensity after four hours of using the patch. (Rowbotham, M. C. et al., 1996) (Food and Drug Administration, 2022) Experts may suggest using patches for four weeks for those who experience pain after their shingles rash disappears. However, if there is still pain after these four weeks, it is recommended to see a pain specialist. (Gross, G. E. et al., 2020)

Side Effects

Common side effects are typically mild skin reactions where the patch is.  These reactions are usually temporary and will disappear within a few minutes or hours. Examples include: (Food and Drug Administration, 2022)

  • Irritation
  • Itchiness
  • Abnormal or burning sensation
  • Redness
  • Swelling
  • Blisters
  • Bruises
  • Skin bumps
  • Skin color changes
  • Skin peeling

Potentially serious side effects include: (Food and Drug Administration, 2022)

Serious Allergic Reaction

  • Severe allergic reactions are rare, but it is possible.
  • Symptoms include breathing problems, itchiness, and rash.

Methemoglobinemia

  • Methemoglobinemia is a condition that makes it hard for red blood cells to carry oxygen.
  • Individuals may experience symptoms of blue-looking skin, headache, lightheadedness, shortness of breath, abnormal heart rhythm, or seizures.

Using too many lidocaine patches to cover large parts of the body or using the patches longer than 12 hours within 24 hours may cause side effects that may include heart-related effects, such as a slow heart rate and low blood pressure.  Individuals may also experience the following side effects (Food and Drug Administration, 2022)

  • Hot or cold sensation
  • Numbness
  • Dizziness
  • Ringing ears
  • Lightheadedness
  • Mood changes
  • Drowsiness to unconsciousness
  • Vision changes
  • Seizures
  • Tremors
  • Vomiting

Cobb Angle: From Measurement to Treatment Decisions

The Cobb angle is a mathematical measurement tool for assessing the curvature of the spine. Along with physical exams and other tests, how is it used to evaluate scoliosis and kyphosis of the spine?

Cobb Angle

The Cobb angle is used to quantify the curvature of the spine, particularly in conditions like scoliosis. It measures the degree of side-to-side spinal curvature, a deformity called scoliosis. The angle’s size helps determine what kind of treatment is needed. Monitoring may be all that’s necessary for mild curvature. With severe scoliosis, treatment may require spinal fusion surgery. Named for orthopedic surgery pioneer John Robert Cobb, it describes the distance a scoliotic curve may deviate from being straight. (Botterbush K. S. et al., 2023) Generally, it takes at least 10 degrees of deviation from straight before scoliosis is confirmed.

X-Ray and Interpretation

An X-ray is taken to measure the Cobb angle. Side and back views are taken. The healthcare provider or examiner then views the X-rays and locates the most affected vertebra in the curve, called the apical vertebra. In a scoliotic curve, the apical vertebra is the spinal bone with the greatest degree of rotation that takes the biggest curve away from the center of a normal spine column.

Visualizing the Angle

The apical vertebra is where two lines drawn from the X-rays meet. Two lines are drawn along the edge of the top and bottom bones of the curve. The lines extend out as follows:

  • On the top bone, the line starts on the high side, continues along the top edge, and then slopes down according to the angle of the vertebra. (Jin, C. et al., 2022)
  • On the bottom vertebra, the line starts on the low side, continues along the bottom edge, and slopes upward.
  • The Cobb angle is found by measuring the angle of the two intersecting lines where they meet.

Then, the top and bottom vertebrae of the side-to-side curve are identified to create a number for the Cobb angle. These bones have the most tilt but the least rotation and displacement and are located above and below the apical vertebra. Computer software is commonly used to calculate the Cobb angle. (Jin, C. et al., 2022) Treatment is based on the:

10 Degrees Cobb Angle 

Scoliosis is diagnosed when the Cobb angle reaches 10 degrees or more. However, this is not generally considered a significant curvature (American Association of Neurological Surgeons, 2024). In around 80% of cases, the scoliosis is considered idiopathic or without congenital or other underlying causes.

Less Than 25 Degrees Cobb Angle

If a scoliotic curve is less than 25 degrees, individuals may only need to visit their healthcare provider periodically so long as the scoliosis is monitored. These are mild cases, often without symptoms, but there is a chance that the curvature can progress. This usually means reassessing the Cobb angle every four to six months in a growing child or adolescent. (National Scoliosis Foundation, 2015) A 5-degree or more progression can change the diagnosis and treatment. (Jin, C. et al., 2022)

Between 25 and 40 Degrees Cobb Angle

A Cobb angle of 25 to 40 degrees usually requires wearing a back brace and intensive physical therapy. The goal of these treatments is to help halt the curve’s progression. Braces are generally worn 16 to 23 hours every day. (National Scoliosis Foundation, 2015) The healthcare provider will provide a referral for physical therapy. Many report excellent results with the Schroth or other scoliosis-specific exercise methods. A study found that core stabilization exercise programs can decrease Cobb angles in adolescents with idiopathic scoliosis. (Ko K. J. & Kang S. J. 2017)

Scoliosis in Adults

Scoliosis is diagnosed in adults, usually in those who have had the condition, treated or not, that was identified in their youth. A study that followed various cases for 20 years found disease progression occurred in 40% of adults but was usually less than one degree per year. However, degenerative scoliosis can also occur in individuals aged 65 and older. (American Association of Neurological Surgeons, 2024)

40 Degrees or More Cobb Angle

Surgery may be recommended once the Cobb angle reaches 40 to 50 degrees. A spinal fusion is often used to force the curve to stop developing. In adults, surgery may be needed if the angle reaches 50 degrees and they experience complications, such as nerve damage or bowel/bladder dysfunction. Risk factors in adults include older age, a history of smoking, and a diagnosis of other conditions, including being overweight. (American Association of Neurological Surgeons, 2024)

Variations

Variations occur in measuring scoliosis, and it is important to understand the difference between a change in scoliosis and a change in the tools or measurement. Equipment errors, imaging errors, and the subjective reading of the healthcare provider can change the values. (Jin, C. et al., 2022) Scoliosis measurement software and intelligent medical devices continue to improve how scoliosis is evaluated and treated. Physical exams, symptoms, and careful monitoring of changes in posture or function are still critical to an accurate diagnosis. The healthcare provider will explain the Cobb angle and other test results.
