Functional Improvement Techniques (FIT) is a complementary technique of a specific hands-on and instrument-assisted manual therapy treatments in order to improve the function of soft tissue (muscles, tendons, ligaments, fascia, and nerves) and joint. The core effect of FIT is of quick and significant functional improvement of soft tissue and joint in overall performance by breaking up myofascial restrictions and scar tissue adhesions resulting from repetitive motion and muscular over-use which cause pain and restrict body movements. FIT involves a physical examination by using hands and stainless steel instruments to identify the area of soft tissue and joint restriction. Precise digital pressure and delicate stainless steel instrumental scraping are applied to the area of the restriction having the patient to perform specific active and passive movements against the practitioner's digital and instrumental resistance to shorten and lengthen the affected soft tissue
