Personal TENS Devices: A Modern Approach to Pain Relief

For individuals managing chronic pain conditions, can incorporating a personal TENS device help?

Personal TENS Device

Almost all physical therapy, chiropractic, acupuncture, and massage clinic healthcare providers offer TENS (transcutaneous electrical nerve stimulation) therapy. Individuals can buy a TENS unit for on-the-go and home care use. A personal TENS unit is a small, battery-powered device that uses low-voltage electrical currents delivered through electrodes placed on the skin to help relieve pain.

How It Works

TENS units work by stimulating nerve fibers in pain, which can help block pain signals from reaching the brain or by stimulating the release of endorphins, the body’s natural pain-killing chemicals.

Uses

TENS units are used to treat a variety of conditions, including:

  • Arthritis 
  • Muscle cramps
  • Neck pain
  • Back pain
  • Pelvic pain
  • Knee pain
  • Osteoarthritis
  • Fibromyalgia
  • Tendinitis
  • Bursitis
  • Diabetes-related neuropathy
  • Pelvic pain from periods or endometriosis

Features

Portability

  • TENS units are small, lightweight, and portable, making them convenient for home or on the go. It can be held in a pocket or clipped to a belt. (National Health Service UK, 2025)

Electrodes

  • The unit is connected to a series of electrodes placed on the skin to deliver the electrical charge.

Adjustable Settings

  • Many TENS units allow users to adjust the electrical pulses’ intensity, frequency, and duration.

Benefits

Non-Invasive

  • TENS therapy is a non-invasive method for relieving pain.

Drug-Free

  • It can provide pain relief without the need for medication.

Convenient

  • TENS units are small, portable, and relatively discrete.

Precautions

Consult a healthcare provider before using a TENS device to ensure its safety for you and your injury/condition. The treatment should not be used for individuals who are pregnant, have epilepsy, poor sensation, a heart problem, a pacemaker, or another electrical or metal implant in their body. (National Health Service UK, 2025) The electrodes should not be placed on certain areas of the body, including (Teoli D, Dua A, An J. 2025)

  • Head
  • Eyes
  • Mouth
  • Front of the Neck
  • Chest and upper back at the same time
  • Numb areas
  • Broken skin
  • Tumors

There is a minor risk of skin irritation, particularly if allergic to the adhesive pads.

Effectiveness

Researchers are still determining how effective TENS units are for relieving and reducing pain. A study found that TENS was effective in relieving pain for patients with fibromyalgia. (Dailey D. L. et al., 2013) Another study suggested that TENS may improve bone pain for cancer patients, but the results were inconclusive because of the limited number of randomized trials. (Vance C. G. et al., 2014)

Research suggests that some factors can impact the effectiveness of the intervention. Varying the intensity and frequency may help it be more effective so the body doesn’t develop a tolerance to it. In addition, using the electrodes in areas that are acupuncture points may help to reduce pain. While further study is needed, TENS is considered a safe pain-relief option for many conditions because it’s non-invasive and doesn’t require medication. (Vance C. G. et al., 2014)

Injury Medical Chiropractic & Functional Medicine Clinic

Individuals interested in trying a personal TENS unit should consult their healthcare provider. They may be able to refer them to a physical therapist, who can show them which type and how to use it for their particular condition. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to develop an optimal health and wellness solution. We focus on what works for you to relieve pain, restore function, and prevent injury. Regarding musculoskeletal pain, specialists like chiropractors, acupuncturists, and massage therapists can help mitigate the pain through spinal adjustments that help the body realign itself. They can also work with other medical professionals to integrate a treatment plan to resolve musculoskeletal issues.

Pulled Muscle: Understanding the Healing Process

What are the recommendations for a pulled muscle injury to fully recover?

Pulled Muscle Recovery Time

A pulled muscle, medically known as a strain, occurs when muscle fibers are stretched too far and sometimes tear. A pulled muscle injury typically starts to heal within days. Mild injuries can heal completely in one to three weeks, but more serious strains or tears, depending on the severity, can take six to 12 weeks or longer. (Fernandes T. L., Pedrinelli A., & Hernandez A. J. 2015)  Rest, hydration, healthy foods, and slowly returning to activity can help expedite healing time.

Timeline

The timeline for recovering from a pulled muscle depends on the injury’s severity.

Pulled muscles are typically categorized into three grades based on the degree and size of pulled muscle fibers, as follows (Hospital for Special Surgery, 2024)

Grade 1 (mild)

  • Heals in a few days.
  • A microscopic tear or stretch in the muscle fiber.
  • It might feel sore, but you can still use the muscle.

Grade 2 (moderate)

  • Heals in four to six weeks.
  • A partial tear in the muscle causes noticeable pain and swelling, making it harder to move or use the injured muscle.

Grade 3 (severe)

  • Heals in several months
  • This type of muscle strain causes a complete tear, also known as a rupture.
  • It results in intense pain, significant swelling, and inability to use the muscle.
  • Surgery may be required in some cases.
  • Larger muscles, such as the hamstrings and quadriceps, may take longer to heal than smaller muscles due to their increased size and greater weight-bearing loads.

Body Parts More Susceptible To Injury

The following are more susceptible to muscle strains, pulls, or tears (Nölle L. V. et al., 2022)

  • Neck – levator scapulae and trapezius
  • Shoulders – rotator cuff muscles
  • Lower back – erector spinae
  • Groin – adductors
  • Front of the thigh – quadriceps
  • Behind the thigh – hamstrings
  • Calves – gastrocnemius and soleus

Healing Stages and Factors

Pulled muscles heal in three predictable stages, though the timing and progression may vary by individual and injury severity (Baoge L. et al., 2012).

Inflammatory Stage (zero to three days)

  • When pulling a muscle, the body reacts instantly with an inflammatory response that may include swelling, redness, bruising, and pain.
  • Rest is important during this stage to prevent the injury from getting worse.

Repair Stage (three to 21 days)

  • Damaged muscle fibers are repaired and regrow during this stage.
  • Collagen fills in any tears to rebuild damaged muscle tissue.
  • Gentle movement and easy activity can help the fibers line up properly and reduce stiffness.
  • Start slowly moving a pulled muscle as soon as possible, but avoid too much activity too soon, as it can delay and prolong healing.

Remodeling Stage (three weeks to one year)

  • Repaired tissue gets stronger and adapts to regular movement.
  • Scar tissue may form.
  • Gradually adding more activity, stretching, and strengthening exercises helps treat a pulled muscle and return to full strength and function but should be done carefully to avoid re-injury.

Faster Healing

To help speed up recovery from a pulled muscle, try these simple strategies: (Baoge L. et al., 2012) (Laumonier T. & Menetrey J. 2016)

Rest

  • Avoid activities that cause pain, but move the muscle gently to prevent stiffness.
  • Prolonged rest can slow healing, so maintain a balance between rest and exercise.

Ice

  • Add ice for 10–20 minutes for the first 48 hours to reduce swelling and pain.
  • Ice helps control inflammation by limiting blood flow to the injured area.

Compression

  • Use compression stockings or wrap the injured part in bandages to help reduce swelling.
  • Ensure the binding is not too tight so circulation is not cut off.

Elevation

  • Raise the injured area above heart level throughout the day.
  • This helps reduce swelling by allowing fluids to drain away from the injury site.

Heat

  • After the first two to three days, heat therapy increases blood circulation and improves flexibility, helping the muscle heal.

Eat Healthy

  • Get enough protein for muscle repair.

Maintain Hydration

  • Drink plenty of water to help with circulation and muscle lubrication.

Massage and Physical Therapy

  • These hands-on interventions can improve circulation, help reduce scar tissue, and restore range of motion.

Over-the-counter Medications

  • If needed, over-the-counter nonsteroidal anti-inflammatory medications like Advil or Motrin (ibuprofen) and Aleve (naproxen sodium) can help with pain and swelling.
  • Only use as directed.

These steps can help promote faster healing and expedite returning to normal daily activities.

When to Resume Normal Activity

Individuals may need one to two weeks to recover before resuming normal activity for mild strains. However, for more severe injuries, it could take four to six weeks or longer to return to all daily activities. (Harvard Health Publishing, 2023) It’s essential to gradually return to daily activities to avoid reinjury, which can delay and prolong healing. Follow these recommendations to recover from a pulled muscle safely and quickly (Kraemer W., Denegar C., & Flanagan S. 2009)

  • Once the pain has subsided, the swelling has decreased, and the muscle feels better, start with low-impact exercises.
  • Slowly resume normal activities, avoiding overexerting the injured area.
  • Gradually increase activity levels and stop if there is any pain.
  • Avoid strenuous activities that place excessive stress on the injured muscle until the muscle is completely healed.

Contact a Healthcare Provider

While most pulled muscles heal with home care, seek medical attention if: (Penn Medicine, 2023)

  • Pain persists or worsens after seven to 10 days.
  • This can indicate a more serious injury, such as a severe torn muscle.
  • Significant pain, loss of motion and strength, and swelling disrupt daily activities or show signs of worsening despite rest and self-care.
  • It is difficult to move the affected area, or the muscle cannot bear weight, suggesting a more severe injury.
  • There are signs of infection, including redness, warmth, increased swelling, or fever, especially if the skin is cut or broken near the injured area.
  • There is unusual bruising or a visible deformity, which could indicate a bone fracture requiring professional evaluation.

A healthcare provider may recommend imaging studies, such as MRI, ultrasound, or X-rays, to assess the extent of the injury, rule out fractures, or check for muscle tears.

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

Injury Medical Chiropractic and Functional Medicine Clinic

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. They can also work with other medical professionals to integrate a treatment plan to resolve musculoskeletal problems.

Key Exercises in the Treatment of Achilles Tendonitis: A Protocol

Can incorporating an exercise program like the Alfredson Protocol help athletes and individuals who have hurt their Achilles tendon find pain relief and healing so they can return to regular physical activities?

Exercise Protocol Achilles Tendonitis

Achilles tendonitis occurs when the tendon at the back of the ankle gets injured. It is common in runners. For individuals who have Achilles tendonitis, walking and running can be painful. You might have to stop engaging in exercise and physical activities like sports. Depending on your job, having the condition may make working harder. Here are a few of the signs and symptoms of the condition:

  • Pain in the back of the lower leg, just above the heel.
  • Pain with running, jumping, or pointing the toes.
  • A small lump on the Achilles tendon just above the heel.

The first line of treatment is to rest and ice the tendon. Anti-inflammatory medications can help reduce pain. (American Academy of Orthopaedic Surgeons, 2022) Physical therapy can include strengthening exercises, ultrasound heat therapy, and deep massage. Exercises stretching the nearby muscles will help gradually increase the stress the tendon can handle, eventually reducing inflammation and swelling. Stretching and flexibility exercises will help an Achilles tendon heal. (University of Michigan, 2023)

The only way to determine if an individual has injured their Achilles tendon is to see a doctor. If the injury is Achilles tendonitis, a physical therapist may be recommended. A physical therapist can train individuals on the Alfredson protocol, an exercise protocol program for those with Achilles tendonitis (tendinopathy) that research has shown is helpful for those with the condition. The therapist will train on how to exercise to strengthen the tendon. The exercises stretch the Achilles tendon to help it handle forces and stress, known as eccentric loading. (Stevens M., & Tan C. W. 2014)

Inflammation

Tendonitis is inflammation of a tendon. However, studies have shown that the tendon might not be inflamed in those with the condition. When an area of the body is inflamed, inflammatory cells are present. Individuals usually feel pain in the inflamed area. For those with Achilles tendonitis, the tendon will present with pain, but not necessarily because the tendon is inflamed. Under a microscope, researchers examined tissue from the tendons of those with Achilles tendonitis. They did not find inflammatory cells in the tissue. (Stevens M., & Tan C. W. 2014) This means that although individuals felt pain, they were not inflamed. If there are no inflammatory cells in the tendon, this could explain why those with Achilles tendonitis often do not find relief from the anti-inflammatory treatment of non-steroidal anti-inflammatory drugs (NSAIDs). Studies have shown that gentle exercise protocols for the tendon are more helpful. However, researchers are not sure why these exercises are so beneficial. (O’Neill S., Watson P. J., & Barry S. 2015)

Eccentric Exercise

A chiropractic physical therapy team can help individuals heal the injury with eccentric loading exercises. Eccentric loading exercises work the muscles and tendons to help them get stronger. Once healing has begun, they can help strengthen the tendon. Individuals start slowly with easy exercises and then work up to harder ones. They will have the patient lengthen or stretch out the muscle. As the patient moves, the muscles and tendons contract or shorten. The Alfredson protocol consists of eccentric loading exercises for the Achilles and the muscles that support it.

Alfredson Protocol

Before exercising, talk to a doctor or physical therapist to know if it’s safe. How to do the Alfredson protocol:

  1. First, stand on a small step or curb.
  2. Stand with the balls of your feet on the edge.
  3. Your heels should hang over the edge.
  4. Hold onto something for balance.
  5. Keep the knees straight.
  6. This will load a muscle part of the Achilles tendon called the gastrocnemius.
  7. Using both feet, lift the heels and rise onto the balls of the feet.
  8. Keep the foot with the painful Achilles tendon on the step.
  9. Lift the non-injured foot off the step.
  10. Slowly lower down using the injured ankle.
  11. The heel should move towards the floor.
  12. The ball of the foot should remain in contact with the edge of the step.
  13. Return the non-injured foot to the step.
  14. Repeat the exercise.

Do three sets of 15 reps with the knees straight. Then, do the Alfredson protocol again with the knees slightly bent. This will work a muscle called the soleus, which connects to the gastrocnemius. Perform three sets of 15 repetitions. Perform both exercises twice a day. This could be in the morning and the evening. The Alfredson protocol is most beneficial when done for about 12 weeks. (Stevens M., & Tan C. W. 2014)

Injury Medical Chiropractic and Functional Medicine Clinic

The Alfredson exercise protocol can be done at home with a step or raised platform to put the feet on safely. Individuals should consider working with a personal trainer to ensure safety and get the most out of the workouts. 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.
