During IASTM, a physical therapist uses specialized tools to glide over the skin and underlying tissues. The instruments help identify areas of restricted movement, increased tissue density, or altered muscle tone.

The technique is believed to stimulate a localized response in the treated tissue, which may help improve mobility and promote the body’s natural healing processes. IASTM can also reduce excessive muscle tension and improve how soft tissues move during activity.

Treatment is always tailored to the individual and performed within a broader rehabilitation plan. Your therapist will consider your injury history, movement limitations, and goals when deciding how IASTM fits into your care plan.

IASTM is commonly used for areas affected by scarring, chronic overuse, or limited soft-tissue mobility. Mild soreness or tenderness may occur after treatment, and your therapist will explain what to expect and how to manage post-treatment symptoms.

When used appropriately, Instrument Assisted Soft Tissue Mobilization may support recovery and improve movement quality. Potential benefits include:

• Improved soft-tissue mobility and flexibility
• Reduced muscle tension and stiffness
• Support for recovery from post-surgical or traumatic scarring
• Enhanced outcomes when combined with therapeutic exercise
• Improved tolerance to movement and activity

IASTM is often used for conditions such as chronic tendinopathies, post-operative stiffness, soft-tissue restrictions, and injuries involving reduced tissue mobility. Your ATI physical therapist will determine if this technique is appropriate based on your condition, medical history, and overall plan of care.

Instrument Assisted Soft Tissue Mobilization is one of many tools ATI therapists may use to help patients move more comfortably and return to activity with confidence.
