INSTRUMENT ASSISTED SOFT TISSUE MOBLIZATION (IASTM)

Instrument Assisted Soft Tissue Mobilization (IASTM): Precision Treatment for Stiff, Restricted Tissue

Instrument Assisted Soft Tissue Mobilization (IASTM) is a hands-on treatment that uses specialized tools to help identify and treat tight, restricted, or injured soft tissue. By applying controlled pressure along muscles, tendons, and connective tissue, IASTM helps restore normal movement and reduce pain.

This technique is especially helpful when tissues feel thick, stiff, or resistant to stretching.

How IASTM Works

During IASTM, your physical therapist:

  • Uses a specially designed instrument to scan and treat restricted tissue

  • Applies precise pressure to break down adhesions and scar tissue

  • Stimulates healing by improving blood flow and tissue mobility

The instruments allow for a more specific and effective treatment than hands alone.

What Conditions Does IASTM Help With?

IASTM is commonly used to address:

  • Muscle tightness and stiffness

  • Tendon irritation and tendinopathy

  • Scar tissue following injury or surgery

  • Chronic soft tissue pain

  • Overuse and repetitive strain injuries

It is frequently used on the shoulders, hips, knees, calves, Achilles tendon, plantar fascia, forearms, and back.

Why IASTM Is Different

IASTM stands out because it:

  • Targets specific dysfunctional tissue, not general areas

  • Helps detect restrictions that may be difficult to feel by hand

  • Prepares tissues for movement, strengthening, and sport-specific training

This makes it an excellent complement to active rehabilitation and return-to-sport care.

What Does IASTM Feel Like?

Patients often describe IASTM as:

  • A scraping or pressure sensation

  • Mild to moderate discomfort that eases quickly

  • Followed by improved mobility and reduced stiffness

Temporary redness or mild soreness can occur and is a normal response.

How We Use IASTM in Your Care

IASTM is not a stand-alone treatment. It is combined with:

  • Therapeutic exercise

  • Mobility and stability training

  • Strength progression

  • Sport- or activity-specific movement work

The goal is to improve tissue quality so your body can move and load more effectively.

Is IASTM Right for You?

IASTM may be appropriate if you:

  • Feel stiff or restricted despite stretching

  • Have persistent tendon or soft tissue pain

  • Are returning to sport or training

  • Want a targeted, evidence-based treatment approach

Your physical therapist will determine if IASTM fits your condition and goals.

Our Philosophy

We don’t just loosen tissue—we restore function.

IASTM helps create the mobility and tissue health needed for long-term recovery, performance, and injury prevention.
