Scapular Muscles Strength of Different Age Groups in the Indian Population

Background: Poor scapular muscular strength and scapular dyskinesis are the causes of scapular discomfort. Objective: The aim of this study was to assess the normative values of isometric scapular muscle strength and examine the impact of body mass index (BMI), age, weight, height, and gender on scapular strength. Method and Materials: A portable dynamometer was used to test the isometric scapular muscular strength of the adult volunteers. A multivariate analysis was conducted to examine the impact of age, weight, height, gender, and BMI on scapular muscular strength, and normative strength values were determined. Results: For both genders, normative ranges were discovered, which would serve as a guide in the risk assessments of muscle weakness and strength. Compared to females, men are less likely to experience strength and weakness. Scapular muscular strength was favorably correlated with both age and weight. Muscle strength is not influenced by height or BMI. Conclusions: This study will offer the basic framework for the normative ranges of scapular muscle strength in the adult population, assisting in the prevention, maintenance, and treatment of scapular muscle weakness. The clinician will be able to compare the muscle strength of various age groups using this standard.
