About

Chronic low back pain (CLBP) is the most common medical problem observed among musculoskeletal pain and spinal pain problems. It can reduce the movements due to muscular imbalances, decreased activity of daily living, and effects on health-related quality of life. It is the major cause of activity limitation, work absence, and reported clinical issues. Most of the cases of low back pain remained undiagnosed and received only symptomatic management.

Full description

There is limited literature on advanced soft tissue release techniques provided by primary healthcare practitioners specific to low back pain. Some of the studies are based on soft tissue mobilization using a mechanically assisted method, but they have limited outcomes, acute effects, and small sample sizes, which limit their generalization. Further literature is limited in the comparison of IASTM and SASTM. Further, there are limited techniques that can facilitate practitioners to identify the restrictions.

Firstly, instrument-assisted soft tissue mobilization (IASTM), due to its body contour and shape, recognizes specific tissue lesions and restriction sites while targeting specific points rather than using manual methods that cover a larger contact area. Using the mechanotransduction phenomenon, its mechanical stimuli initiate biochemical signals that trigger cellular responses and ultimately functional improvement. Biomechanically, fascial elasticity, fascial stiffness, and viscosity absorb and distribute forces. While tissue hydration level is increased, that is compromised in chronic low back pain.

Secondly, sound-assisted soft tissue mobilization could be an intervention for treating musculoskeletal disorders. The SASTM technique has the potential to be a game-changer in pain management after IASTM. The sound decreases as adhesions are broken. While breakdown of scar tissue can be a facilitator for ease of movement patterns.
