Definition:
IASTM is a manual therapy technique that involves the use of specialized instruments to assist clinicians in detecting and treating soft tissue dysfunction. These instruments allow for deeper and more precise treatment of muscles, fascia, tendons, and ligaments compared to traditional hands-on techniques.

Instrument-Assisted Soft Tissue Mobilization (IASTM) is a specialized technique used in physiotherapy to treat soft tissue dysfunctions using hand-held instruments. These tools are typically made of stainless steel or hard plastic with beveled edges, allowing therapists to effectively detect and treat fascial restrictions, scar tissue, and chronic inflammation. The technique involves applying controlled microtrauma to the affected area, which stimulates a localized inflammatory response. This response promotes tissue remodeling, enhances blood flow, and facilitates the healing of dysfunctional soft tissues. IASTM is commonly used for conditions such as tendinopathies, ligament sprains, muscle strains, plantar fasciitis, and myofascial pain. It can improve range of motion, reduce pain, and restore normal function when combined with stretching and strengthening exercises. While generally safe, IASTM may cause temporary redness, bruising, or soreness, and it should be used cautiously in individuals with certain conditions like open wounds, infections, or bleeding disorders. Overall, IASTM is an effective and evidence-supported technique to enhance soft tissue recovery and performance.
