Scar Tissue Massage and Management

Physical therapists commonly use scar tissue massage to help remodel scar tissue that has developed in injured tissue. You might have this type of physical therapy after you experience an injury that results in a buildup of scar tissue, including:

• Surgery
• Fracture
• Soft tissue injuries like sprains and strains

This article explains how scar tissue develops and the techniques involved in managing it.

What Is Scar Tissue?

Collagen (a protein found in muscles, bones, and other tissues) forms scar tissue. After an injury, your body lays down collagen that will become normal healthy tissue.

Collagen that develops under typical, healthy circumstances align to give your tissue strength. However, the collagen cells that form in response to an injury do so randomly. This sporadic layering leads to the buildup of scar tissue.

Scar tissue can develop almost anywhere in the body. Some examples of how scar tissue appear include:

• After surgery: Scar tissue will develop where the surgical incision is. For example, if muscles and tendons were cut or repaired, scar tissue would grow there.
• After muscle injuries: In a hamstring tear or rotator cuff tear, scar tissue will develop in the muscle as it heals.
• After a fracture: Bony scar tissue, called a callus, will form on the bone after a fracture.

Is Scar Tissue Permanent?

Scar tissue is not a permanent fixture in the body. After it forms and heals, the scar must remodel.

Remodeling is a natural part of the healing process. During remodeling, your body rebuilds the scar so that it becomes stronger and more similar to the tissue that was there before the injury. This adjustment is necessary so the new tissue can tolerate the stress and forces that the body typically experiences in a day.

Remodeling is essential to ensure that your injured tissue regains normal range of motion, strength, and mobility. When scar tissue doesn’t remodel correctly, it can lead to mobility loss and joint contractures (a shortening and tightening of fibers that make movement difficult).

Scar Tissue Management Techniques

If you have developed scar tissue after an injury or surgery, your physical therapist (PT) may perform a scar massage on the injured tissue to help with the remodeling process. They may also instruct you or a family member how to massage scar tissue properly.

In addition, massaging an unhealed scar may open it and lead to bacteria and infection in your body. That’s a bad thing.

Lubrication

Usually, PTs use a small amount of lubrication during scar massage such as baby oil, lotion, or vitamin E oil. Lubrication keeps the scar and skin flexible and soft during scar tissue massage.

Cross Friction Massage

One effective method of scar massage is called cross friction or transverse friction massage. This technique involves using one or two fingers to massage along the scar line.

PTs commonly use cross friction massage to treat the following:

• Tendonitis
• Muscle strains
• Ligament sprains

The technique is performed for five to 10 minutes. If instructed to do so, you may be able to perform scar tissue massage on yourself two to three times per day.

Myofascial Release

Myofascial release (MFR) manages scar tissue and the adhesions that may accompany it. The technique involves using the hands to massage the skin and underlying tissues around the scar.

Motions are slow, and the amount of force is usually light. Your PT can feel for tissue restrictions, called fascia, in various directions. They can then work to improve movement in those restricted directions.

Instrument Assisted Scar Tissue Massage

A relatively new technique used in physical therapy is called instrument-assisted soft tissue mobilization (IASTM). This technique uses special stainless steel instruments of various shapes and sizes to massage and move tissues. Your PT may use this technique by rubbing your scar tissue with an instrument to “break up” the tissue.

However, research to date hasn’t made a compelling case for the effectiveness of IASTM.

Stretching

Another standard method to help remodel scar tissue is stretching and flexibility exercises. Stretching can help lengthen the injured tissues and improve their overall movement.

Stretching scar tissue may be an essential component of your recovery. Most PTs agree that prolonged, low-load stretching (slow, moderate stretching held for a long time) is necessary to help you fully remodel scar tissue.

Scar Management After Fracture

The scar tissue in the bone is called callus. It is present for four to 12 weeks after a fracture.

If you have broken a bone and have started physical therapy, your therapist may massage the overlying tissue near the callus. This technique helps restore normal mobility. If you have had surgery to repair the broken bone, scar massage over your incision may also help.

Another way to improve callus formation in bone is by performing weight-bearing exercises. The bone grows in response to the stress that is placed on it (Wolff’s law). 

Does Science Support Scar Tissue Massage?

Although more research is needed, some evidence suggests that massages may provide moderate-to-strong pain relief for burn scars. A 2020 meta-analysis examined massage as a type of physical scar tissue management. Specifically, it looked at its effect on: 

• Pain
• Pigmentation
• Pliability (how elastic the scar is)
• Pruritus (itchiness)
• Surface area
• Scar thickness

One study included in the meta-analysis found that massage may significantly improve the pliability of burn scars. The meta-analysis also concluded that massage therapy may have a moderate effect on pruritus.

Two studies in the meta-analysis found that massage could help reduce the thickness of scars, but two other studies found no such benefit. The authors noted that the length of the massage treatment (30 minutes versus 5) may account for the differences in the findings. 

Summary

Scar tissue massage is a form of rehabilitation that uses pulling and stretching to remodel scar tissue. Scar massage helps you regain mobility and strength in your damaged tissue.

PTs use a variety of techniques in scar massage. Additionally, they may instruct you how to do the exercises on your own, at home.

A Word From Verywell

Scar massage has little evidence to support it, but that doesn’t mean it doesn’t work. Anecdotally, plenty of people have found that scar massage helps them move better.

For safety, your wound should be closed entirely before starting scar massage. So, before you receive a scar massage, be sure to check with your doctor to see if it is appropriate in your situation.
