High Intensity Laser vs Instrument-assisted Soft Tissue Mobilization on Trapezius Myofascial Pain Syndrome

The therapeutic dose of laser therapy depends on power density, tissue color, and type. Darker skin may absorb the laser in the epidermal layer, but HILT can pass through without absorption. Research has improved power density and dose, with the World Association of Laser Therapy recommending a 5-7 J/cm2 dose for optimal therapeutic outcomes.

Instrument-assisted soft tissue mobilization is a popular alternative to traditional manual therapy techniques, derived from Cyriax cross-friction massage. It uses hard tools to manipulate soft tissue, varying in direction, force, and pattern, and allowing pressure to disperse to underlying tissues. Modern Instrument-assisted soft tissue mobilization instruments vary in material and design, and are used to improve musculoskeletal conditions and outcomes. Patients receive Instrument-assisted soft tissue mobilization with an M2T blade, positioned at a 45° angle, and instructed to apply an ice pack if experiencing burning sensations.

conventional physical therapy, which includes ultrasound, isometric neck exercises, chin tucks, stretching of neck muscles, and neck stabilization exercises, were used for groups A, B and C
