Correlation of Trapezitis with Scapular Dyskinesia and Hand Grip Strength in Academicians

Background: The scapula is vital to the upper limb kinematic chain and gleno-humeral rhythm. Scapular dyskinesia, caused by abnormal scapular movement, often leads to pain. Overhead tasks like writing and grading can cause muscle imbalances. This imbalance disrupts scapular mechanics and grip strength by reducing force transfer efficiency along the arm. Methodology: After obtaining written informed consent from the academicians, the procedure was explained to them, and participants were selected based on the inclusion criteria from various schools and colleges in Ahmedabad. Scapular dyskinesia, trapezitis, and grip strength were assessed using the Lateral Scapular Slide Test, Visual Analog Scale, and Jammar Handheld Dynamometer, respectively. Results: A total of 9 males and 41 females were included in the study. The mean ± SD of age was 31.64 ± 4.52 years, teaching hours were 4.8 ± 0.75 hours per day, and years of experience were 7.26 ± 1.32 years. The data was not normally distributed; therefore, the Spearman rank correlation test was used. LSST1 showed Week positive statistically significant correlation with VAS (r = 0.168, p = 0.243) or grip strength (r = 0.243, p = 0.134). LSST2 showed a Strong positive statistically significant correlation with VAS (r = 0.609, p = 0.001) and grip strength (r=0.312, p = 0.027). LSST3 showed a moderate positive statistically significant correlation with VAS (r = 0.504, p = 0.001) and grip strength (r = 0.323, p = 0.022). Conclusion: In conclusion, trapezitis is positively correlated with scapular dyskinesia and reduced grip strength in academicians. Key words: Lateral scapular slide test, Visual analogue scale, Scapular Dyskinesia, Grip strength.
