The aim of the study is to evaluate the prevalence and anatomical locations of muscle tenderness among adults with nonspecific neck/shoulder pain but without any traumatic injuries and other serious chronic disease.
To find various causes for nonspecific neck/shoulder pain.
Many adults experience bothersome neck/shoulder pain. It is the one of the common symptom in primary care. It can be due to an intrinsic shoulder problem but pain can also be referred from other structure, such as the neck, diaphragm or heart. METHODS: This study required 50 patients those who are suffering from non specific shoulder or neck pain by examining the tenderness for the selected shoulder muscle. Inclusion criteria for this study was confined to the patients with nonspecific shoulder pain with age limit 30–55, and duration of pain about more than 6 months. Exclusion criteria for selection of patients for this study were limited to traumatic injuries, any other chronic disease cardiovascular disease, osteoporosis, arthritis and pregnant women. Then examination for muscle tenderness was done by palpating the selected muscles which are Upper Trapezius, Neckextensor, Levator scapulae and Infraspinatus. Based on the patients response during palpation, the examiner used a score of 1–3 corresponding to “ no pain”, moderate pain”, and “ severe pain”. RESULTS: In our present study we found that neck extensors(=0.712>0.500)and levator scapulae(=0.886>0.500) were significant in Chi square test for muscle tenderness for nonspecific shoulder pain. Whereas Upper trapezius and infra Spinatus are found to be not significant for muscle tenderness. While our study also determined that females have tenderness score much more that males. And while comparing the percentage of tenderness score the muscles between sides (right and left side) upper trapezius and neck extensor were significant at the left side where as the levator scapulae and infra spinatus were more significant in right side of the shoulder.
Many studies show that only upper trapezius play a major role in shoulder/neck pain. But there are other related muscles that are also significant or a cause for shoulder/neck pain. Therefore as a conclusion of our study, not only upper trapezius is significant, but also neck extensor, levator scapulae and infra spinatus are also significant for tenderness during shoulder/neck pain. Future research should not only focus on upper trapezius but also on levator scapulae, infra spinatus and neck extensor.
