As a licensed Physical Therapist, I have seen first-hand the benefits of using Instrament-Assisted Soft Tissue Mobilization, or IASTM.
IASTM is a specialized myofascial release technique used during physical therapy treatments, massages, and reflexology. In IASTM, the provider will use a stainless steel tool to allow for deeper penetration of the muscle to decrease pain and increase mobility. This treatment can be especially effective after an injury where you develop tightening of the tissue or restricted range of motion. IASTM can increase circulation and improve cellular activity, thus decreasing the formation of scar tissue.
