How IASTM Works

IASTM uses stainless steel instruments with specially contoured edges to glide over the skin and detect areas of soft tissue restriction — you can actually feel and hear the difference between healthy tissue and areas of scar tissue or fascial adhesion as the instrument passes over them.

Once a restriction is identified, the instrument is used to apply targeted pressure that breaks down the adhesion, stimulates blood flow to the area, and triggers the body’s natural healing response. This promotes the remodeling of scar tissue into healthy, functional tissue that moves the way it should.

IASTM is almost always combined with targeted exercise immediately after treatment — the combination of manual release and active movement is what produces the most lasting results.

Treatment sessions typically take 10 to 20 minutes and are performed as part of a broader physical therapy or treatment session.

What to Expect

One of the most common questions patients have about IASTM is about the bruising and redness that often appears after treatment. This is completely normal — and actually a sign that the treatment is working.

The discoloration you see after IASTM is called petechiae — small areas of bleeding under the skin caused by the instrument breaking down adhesions and stimulating blood flow to the area. It looks more dramatic than it is. Most patients experience mild to moderate redness or bruising that fades within a few days. The treated area may feel tender for 24 to 48 hours after treatment, similar to how muscles feel after a deep tissue massage.

Most patients notice improved range of motion, reduced tightness, and decreased pain either during the session or within the first day or two after treatment. Results continue to improve with successive sessions as the tissue remodels over time.

Treatment intensity is always adjusted based on your tolerance — we work within a range that is effective but manageable, and communication during the session is encouraged.

Conditions IASTM Commonly Treats

IASTM is particularly effective for conditions involving chronic soft tissue restriction, scar tissue, or fascial adhesions. It is commonly used for:

• Chronic muscle tightness and trigger points
• Scar tissue from surgery or injury
• IT band syndrome
• Plantar fasciitis
• Achilles tendinopathy
• Tennis elbow and golfer’s elbow
• Rotator cuff tendinopathy
• Patellar tendinitis
• Hamstring and calf strains
• Neck and upper back stiffness
• Post-surgical adhesions and restricted mobility
• General restricted range of motion

IASTM is almost always used as part of a broader treatment plan rather than as a standalone treatment — it works best when combined with targeted exercise and other manual therapy techniques.

IASTM vs. Massage — What’s the Difference?

A common question is how IASTM differs from regular massage or deep tissue work. The key difference is specificity and depth of effect. Massage uses hands to apply pressure broadly across soft tissue — it is excellent for general tension relief and circulation. IASTM uses rigid instruments that can detect and treat specific areas of restriction at a level of precision that hands alone cannot achieve.

The instruments also allow the clinician to work at a different angle and depth than manual techniques — reaching into tissue planes and fascial layers that are difficult to access with fingers alone. This makes IASTM particularly effective for stubborn, chronic restrictions that have not fully responded to massage, stretching, or standard manual therapy.

IASTM at Noor Physical Therapy is always performed by Dr. Brian Noor, DPT — a licensed physical therapist with extensive training and experience in the technique. This is not a spa service — it is a clinical treatment with a specific therapeutic goal.

Our Goal

Our goal with IASTM is the same as with everything else we do — to address the actual cause of your restriction or pain, not just temporarily relieve it. Soft tissue that moves well heals better, responds better to exercise, and stays healthier over time.

If you have chronic tightness, scar tissue from a previous injury or surgery, or a soft tissue restriction that has been limiting your movement or contributing to pain, IASTM may be a valuable addition to your treatment plan. As your physical therapist in West Los Angeles, we will evaluate whether it is appropriate for your specific situation and integrate it into a plan designed to produce lasting results.
