Instrument Assisted Soft Tissue Mobilization (IASTM) is a skilled myofascial intervention used for soft tissue treatment, based on the principles of James Cyriax's cross-friction massage. IASTM is said to have evolved from Gua sha, a method used in Chinese medicine. It involves the use of instruments, typically made of stainless steel, featuring beveled edges and contours that can conform to various anatomical locations on the body, allowing for deeper penetration. This technique is employed for detecting and treating soft tissue disorders. Studies have explored the cellular-level benefits of IASTM, where controlled microtrauma to affected soft tissue structures initiates an inflammatory response. Clinical studies have also demonstrated improvements in range of motion, strength, and mobility through IASTM. The therapy's advantages include reduced pain and inflammation, increased blood and lymph flow, improved range of motion, reduced post-activity muscle soreness, better sleep, and overall health improvement. It's important to note that IASTM may not be suitable for everyone, as it has specific contraindications and precautions that should be considered before undergoing the treatment.
