Effect of Lower Trapezius and Serratus Anterior Muscle Strengthening on Pain and Function in Patients with Chronic Mechanical Neck Pain

Background Neck pain is considered to be a very frequent and disabling complaint among the general population. Purpose To study the effect of strength training of Lower Trapezius and Serratus Anterior muscles on pain and function in patients with chronic mechanical neck pain. Method 24 chronic mechanical neck pain samples (12 experimental and 12 control groups) participated. The pre and post-assessment was done with Numerical Rating Scale (NRS), Algometer, Push-Pull Dynamometer and Neck Disability Index Scale (NDI) for Pain, Pain Pressure Threshold (PPT), Muscle Strength and Function respectively. The experimental group was given strength training along with conventional physiotherapy whereas the control group underwent only conventional physiotherapy. Results The results showed a statistically significant difference in PPT (p value 0.04), Lower Trapezius strength (p value 0.02), Serratus Anterior strength (p value 0.003) and NDI (p value 0.04). Conclusion Strength training for Lower Trapezius and Serratus Anterior muscles along with conventional physiotherapy should be incorporated in treatment of Chronic Mechanical Neck pain patients.
