Effect of Instrument Assisted Soft Tissue Mobilization on Neck Pain and Range of Motion in Patients with Chronic Upper Trapezitis – A Randomised Control Trial

Background: Trapezitis is an inflammation of the trapezius muscle that leads to the development of myofascial trigger points, often aggravated by poor posture, repetitive strain, or prolonged desk work. A forward head posture further exacerbates muscle tension, resulting in pain, stiffness, and a reduced range of motion. In addition to dry needling and instrument-assisted soft tissue mobilization, other therapeutic approaches such as stretching exercises, postural correction, and strengthening techniques can help alleviate symptoms and prevent recurrence. Lifestyle modifications, including ergonomic adjustments and stress management, also play a crucial role in long-term recovery and muscle health. Methodology: Sixty patients with neck pain and a positive jump sign were randomly assigned to two groups. Group A received conventional therapy, while Group B underwent instrument-assisted soft tissue mobilization (IASTM) in addition to traditional therapy. Group B received three treatment sessions over 10 days. Both groups were provided with Interferential Therapy (IFT), hot pack therapy, and self-trapezius stretching exercises. Result: Both groups showed statistically significant improvement, but the IASTM group was more effective in reducing pain and improving range of motion. Based on the results of the present study, both IASTM and conventional therapy are effective in treating upper trapezitis. However, IASTM has shown greater effectiveness in reducing pain and improving the range of motion. This suggests that IASTM may be particularly beneficial for addressing latent trigger points, as it is applied to the muscle belly. Additionally, IASTM helps reduce local pain, enhances range of motion, and influences neuronal activity. It impacts soft tissues by inducing microtrauma, which stimulates fibroblast proliferation, thereby promoting tissue repair. Conclusion: IASTM is a highly effective treatment option for reducing pain and improving the range of motion in patients with upper trapezitis. Compared to conventional therapy, IASTM proves to be a more effective approach in enhancing muscle function and promoting tissue healing, making it a valuable therapeutic intervention.
