The hypersensitive, palpable nodules known as myofascial trigger points (MTrPs) are located along muscular bundles. They frequently affect the shoulder girdle & cervical muscles. The muscle most usually affected is the trapezius. Trigger points in the neck are thought to be present in 85% of patients who visit pain clinics, and they affect women more frequently than males. In this study we see the effect of Instrumented assisted soft tissue mobilisation (IASTM) on upper trapezius myofascial trigger point. Most studies in our review study reported the IASTM’s usefulness in treating upper trapezius trigger points, but additional research is required.
