6 physical therapy techniques used to break up scar tissue

Scar tissue is a normal part of the body’s healing process after an injury — but sometimes, it doesn’t behave the way healthy tissue does. If you’re dealing with stiffness, tightness or limited movement after an injury or surgery, you might be wondering how to break up the scar tissue and restore more comfortable motion.

The good news is that physical therapy offers several evidence-informed techniques that can help improve how scar tissue moves and feels. While no method can “erase” scar tissue, a physical therapy can create a treatment plan of different approaches that may support better mobility, flexibility and function over time.

Read on to learn the basics about scar tissue and physical therapy techniques may help break it up.

What is scar tissue, and why can it cause problems?

Scar tissue forms when your body repairs damaged skin, muscles or connective tissue. It’s made primarily of collagen, but unlike healthy tissue, it tends to be less organized and less flexible.

In some cases, scar tissue may:

• Limit range of motion

• Create a feeling of tightness or pulling

• Contribute to discomfort with movement

• Affect nearby muscles and joints

Not all scar tissue causes symptoms. But if it begins to interfere with how you move or feel, it may be helpful to address it with guided care.

6 physical therapy techniques used to break up scar tissue

Physical therapists often use a combination of hands-on techniques, movement strategies and progressive exercises to help improve tissue mobility and function in the affected area.

1. Soft tissue mobilization

Soft tissue mobilization is a type of manual therapy, meaning that the physical therapist uses hands-on techniques to apply targeted pressure and movement to the affected area.

This approach involves massage-like movements that may help:

• Improve tissue flexibility

• Reduce stiffness

• Encourage better movement between layers of tissue

It’s often one of the first steps when addressing restricted scar tissue.

2. Myofascial release

3. 
   

Myofascial release is a type of manual therapy that focuses on the fascia, which is the connective tissue surrounding muscles and organs.

With this technique, a therapist applies gentle, sustained pressure to areas of restriction. Over time, this may help:

• Reduce tension in surrounding tissues

• Improve overall mobility

• Decrease sensitivity in the area

3. Instrument-assisted soft tissue mobilization (IASTM)

IASTM uses specialized tools to apply controlled pressure to the skin and underlying tissue.

You may have heard of tools like Graston® or similar techniques. These tools can help therapists:

• Detect areas of restriction

• Apply consistent pressure

• Stimulate local circulation

Some people notice temporary redness or mild soreness afterward, which is a normal response to IASTM.

4. Stretching and mobility exercises

Targeted stretching helps encourage scar tissue to adapt to movement while improving the overall function of the area.

A physical therapist may guide you through:

• Controlled stretches for the affected area

• Joint mobility exercises

• Movement patterns that reduce compensation

These exercises are often progressed gradually to match your comfort and tolerance as you move along your treatment plan.

5. Strengthening and functional training

Scar tissue in one area can affect everything around it, impacting how muscles and joints work together as you move throughout your daily routines.

Strengthening exercises may help:

• Improve support around the affected area

• Restore normal movement patterns

• Reduce strain on surrounding structures

Over time, these exercises can make everyday activities feel easier and more natural.

6. Dry needling (when appropriate)

In some cases, physical therapists may use dry needling to target areas of tightness associated with scar tissue.

This technique involves inserting thin needles into trigger points in the tissue. It may help:

• Reduce muscle tension

• Improve local blood flow to accelerate healing

• Decrease sensitivity in the area

Not every patient is a candidate for dry needling, and it’s always used based on individual needs while considering co-occurring medical conditions.

FAQs about scar tissue and physical therapy 

• Can physical therapy actually break up scar tissue?

Physical therapy may help improve how scar tissue moves and feels. While it doesn’t remove scar tissue, it can support better flexibility, mobility and function.

• How long does it take to improve scar tissue?

This varies depending on the location, severity and age of the scar. Some people notice changes in a few weeks, while others may need longer-term care.

• Is scar tissue treatment painful?

Some techniques may cause mild discomfort, especially at first. However, treatment is typically adjusted to your tolerance and should not feel overwhelming.

• Can I massage scar tissue myself?

In many cases, yes. A physical therapist can show you safe techniques and guide how much pressure and frequency to use.

• What does scar tissue feel like?

Scar tissue may feel tight, thick or less flexible than surrounding tissue. Some people also notice sensitivity or pulling during movement.

• What causes scar tissue to form?

Scar tissue forms as part of the body’s natural healing process after injury, surgery or inflammation.

• Can scar tissue go away on its own?

Scar tissue doesn’t fully disappear, regardless of treatment, but it may become more flexible and less noticeable over time, especially with movement and therapy.

• Is scar tissue the same as a muscle knot?

Not exactly. Muscle “knots” are often related to tension or trigger points, while scar tissue forms from healing after tissue damage.

• When should I be concerned about scar tissue?

If it limits movement, causes ongoing discomfort or affects daily activities, it may be helpful to seek evaluation from a physical therapist.

• Do all injuries lead to scar tissue problems?

No. Many people heal without long-term issues. Problems are more likely when tissue mobility becomes restricted or movement patterns change.
