Augmented soft tissue mobilization is a modality involving the use of specialized tools to assist in the process of releasing soft tissue from tight fascia. Several different augmented soft tissue mobilization techniques exist including Graston and Astym. Incorporation of this modality into a treatment plan for certain musculoskeletal disorders may produce a variety of beneficial effects, such as improving tissue extensibility. Augmented soft tissue mobilization may increase tissue extensibility by realigning damaged collagen fibers and reducing tone resulting in an increase in length of associated soft tissues. This poster presentation will display a review of the literature pertaining to the extent to which augmented soft tissue mobilization is able to increase tissue extensibility.
