Sound-assisted soft tissue mobilization: an innovative approach for musculoskeletal disorders
Article Sidebar
Main Article Content
Abstract
Musculoskeletal disorders remain a major contributor to injury, functional limitation, and long-term disability worldwide. This viewpoint explores emerging approaches to soft tissue mobilization, with a particular focus on sound-assisted soft tissue mobilization (SASTM) as a novel physiotherapy intervention. A broad review of the literature was undertaken, encompassing all available forms of evidence on soft tissue mobilization techniques without restrictions on study design or database source. Instrument-assisted soft tissue mobilization (IASTM), SASTM, manual cross-fiber massage, and related techniques are widely integrated into contemporary rehabilitation programs. Both IASTM and SASTM operate on similar biomechanical principles, applying controlled mechanical forces to soft tissues to disrupt adhesions, enhance local circulation, and facilitate tissue healing. While IASTM employs steel-based instruments to detect and treat soft tissue restrictions through tactile feedback, SASTM utilizes ceramic polymer tools that identify tissue irregularities through sound-based feedback. Although each modality has defined indications and contraindications, SASTM may offer greater specificity in targeting adhesions. Nevertheless, its application should remain adjunctive, used alongside established therapeutic interventions and only by appropriately trained practitioners in accordance with prevailing professional regulations and state bylaws.
