Myofascial release and fascial-targeted mechanical interventions in musculoskeletal rehabilitation: mechanisms, modalities, and integrative physiology

Fascia is a continuous connective tissue network that surrounds and integrates muscles, bones, nerves, and organs, contributing to force transmission, postural organization, movement coordination, and sensory processing within the musculoskeletal system. Any alterations in fascial properties, including increased stiffness, adhesions, and densification, have been associated with pain, restricted mobility, and functional impairment in musculoskeletal conditions. These associations have supported the growing use of myofascial release interventions within rehabilitation practice. Mechanical loading of fascial tissues through pressure, shear, vibration, or acoustic stimulation may influence tissue mechanics and sensory signaling. Across manual, instrument-assisted, and device-based modalities, myofascial release interventions apply these mechanical stimuli through different modes while sharing overlapping physiological targets. Proposed mechanisms include modulation of tissue mechanics, sensory receptor stimulation, and neurophysiological effects on muscle tone and pain perception. Evidence reported in the literature indicates that myofascial release interventions are frequently associated with short-term improvements in pain and joint range of motion. In contrast, findings related to long-term functional outcomes and direct, modality-specific structural adaptation of fascial tissues remain inconsistent. Interpretation of available data is further constrained by heterogeneity in intervention protocols, operator dependence, variable outcome measures, and limited use of objective methods capable of quantifying fascial mechanical properties in vivo . Within an integrative physiological framework, myofascial release interventions are most consistently supported as adjunctive components of musculoskeletal rehabilitation rather than stand-alone treatments. Their clinical value appears greatest when used to facilitate movement, reduce symptom burden, and enhance engagement with active rehabilitation strategies such as exercise and movement re-education. Continued advancement in this field will depend on standardized reporting, improved methodological rigor, longer-term follow-up, and the incorporation of objective assessments to clarify mechanisms and guide evidence-based integration.
