Effect Of Instrument Assisted Soft Tissue Mobilization (IASTM) In Trapezitis -A Literature Review

ABSTRACT Background: Trapezitis is defined as “an inflammation of neck and upper back muscle” i.e. trapezius which involves myofascial pain syndrome. The majority of the time, pain arises due to working in a static position, stress, tension, and non-ergonomic posture. The present review of literature has been undertaken to discover the effect of Instrument Assisted Soft Tissue Mobilization(IASTM) in Trapezitis.Aim and Objectives: To explore the effect of IASTM in reducing pain, inflammation, and muscle tension in trapezitis, while promoting tissue healing and improving overall function. Material and Methods: A systematic search was conducted using databases such as PubMed, ResearchGate, Google Scholar, and Scopus. Articles published between 2019 and 2025 were reviewed, focusing on randomized controlled trials (RCTs) relevant to IASTM. Only English-language publications were included. Keywords used in the search strategy included "IASTM," "trapezitis," "myofascial pain," and "soft tissue mobilization." Conclusion: IASTM is an effective intervention for managing trapezitis, with evidence supporting its role in pain reduction, functional improvement, and tissue healing. Keywords: Trapezitis, Instrument-Assisted Soft Tissue Mobilization (IASTM), Range of Motion, Pain, Myofascial Pain Syndrome.
