How does it work?

Instruments successfully dissect fascial restrictions and scar tissue. The ergonomic shape of the instruments gives the clinician control to find restrictions and enables the clinician to treat the area appropriately with the right pressure.

The application of controlled microtrauma to involved soft tissue structure triggers the local inflammatory response stimulation. Microtrauma triggers reabsorption of aberrant fibrosis or excess scar tissue and allows a cascade of healing processes leading to remodelLing of involved soft tissue structures. Adhesions in the soft tissue that have formed due to surgery, immobilization, repeated strain or other mechanisms are dissolved, making it possible for full restoration of function.

Understanding the Mechanism and Benefits of IASTM at BodyMechanics

At BodyMechanics, we utilize Instrument-Assisted Soft Tissue Mobilization (IASTM) as part of our integrated treatment approach to support soft tissue recovery, reduce discomfort, and improve mobility. This technique is backed by physiological mechanisms that enhance the body’s natural healing response, all while offering benefits for both patients and practitioners.

How IASTM Works at a Physiological Level

IASTM involves the use of specialized tools to apply targeted pressure to soft tissues. This controlled microtrauma initiates an inflammatory response that stimulates the body’s natural repair processes. Key outcomes include:

• Increased fibroblast activity
• Enhanced collagen production and remodeling
• Reduction of fascial restrictions, adhesions, and scar tissue buildup

Fibroblasts—the primary cells in the extracellular matrix—play a crucial role in soft tissue repair. These cells help generate essential components like collagen and elastin. When stimulated through IASTM, fibroblasts can help reorganize damaged tissue structures and support the regeneration of healthy tissue. They also respond to mechanical stimuli (like pressure, stretch, or fluid movement) by triggering biochemical processes necessary for healing.

Neurophysiological Effects of IASTM

IASTM not only impacts the tissue structurally—it also affects the nervous system. The technique stimulates mechanosensitive neurons in the skin and underlying tissues. These include:

• Mechanoreceptors, which influence touch sensitivity and movement awareness
• Nociceptors, which are involved in the perception of pain

By stimulating these neural pathways, IASTM may help reduce pain sensitivity and improve local tactile awareness. Some patients report enhanced sensation, reduced muscle soreness, and improved function following treatment.

Vascular and Circulatory Response

Another important benefit of IASTM is its ability to increase local blood flow. This improved tissue perfusion supports the delivery of oxygen and nutrients to the area, aiding in the healing of injured or restricted soft tissue. This vascular response contributes to faster recovery and greater mobility over time.

Clinical Outcomes Observed at BodyMechanics

Patients who undergo IASTM at BodyMechanics often experience improvements in:

• Range of motion
• Muscle strength
• Pain perception and tolerance
• Overall functional mobility

These outcomes are particularly helpful for individuals recovering from sports injuries, post-surgical stiffness, repetitive strain injuries, or chronic tension in muscles and fascia.

Therapist Benefits and Enhanced Precision

IASTM also offers distinct advantages for practitioners. By using instruments rather than applying all pressure manually, therapists are able to:

• Deliver more precise, deeper treatment with less strain on their hands and joints
• Reduce the risk of overuse injuries, particularly in the thumbs and fingers
• Improve tactile feedback through enhanced vibratory sensation, allowing better identification of areas with tissue restrictions or adhesions

This mechanical efficiency helps ensure consistent, high-quality care while maintaining the therapist’s long-term physical well-being.

Types of Tools

There are numerous firms for IASTM like RockTape®, HawkGrips®, Graston®, Técnica Gavilán®, Functional and Kinetic Treatment with Rehab (FAKTR)®, Adhesion Breakers®, enhanced soft-tissue mobilization or ASTYM®, and Fascial Abrasion Technique™. Each of these firms utilizes a unique approach to treatment with varying design for instruments.

IASTM can be fabricated from different materials such as stainless steel, titanium, plastic, buffalo horn, stone, quartz, and jade. The most popular IASTM instruments utilized are stainless steel.

Practical Application

IASTM can’t be performed alone, it has to be incorporated with motion and strengthening program to aid tissues remodelling.

When IASTM is utilized passes 6 steps

• Examination
• Warm-up is performed for 10-15 minutes by light jogging, elliptical machine, stationary bike or an upper body ergometer
• IASTM, performed at 30-60 degrees angle for 40-120 seconds
• Stretching, 3 sets for 30 seconds
• Strengthening, high reps with low load exercise
• Cryotherapy, 10-20 min

It is crucial to disinfect the instrument between patients to prevent infection transfer. Disinfect the instrument with intermediate-level disinfectants (such as isopropyl alcohol), and then wash it with soap and water to wash away any remnants of the chemical disinfectant off the instrument. If the tools come into contact with blood, bodily fluids, mucous membranes, or non-intact skin then disinfect it using high-level disinfectant.
