Abstract
Objective: To determine the frequency of Pectoralis minor muscle tightness among individuals with asymptomatic shoulder.
Methodology: This cross-sectional study was conducted among 190 individuals with asymptomatic shoulder in Dow university of Health Sciences. A self-administered questionnaire was used for demographical data. Pectoralis minor muscle length was measured and Pectoralis minor index was calculated to assess Pectoralis minor tightness. Data were analyzed using SPSS version 21.
Results: Out of 190 participants, 157(82.6%) were female and 33(17.4%.) male. Mean age, height, weight and body mass index were 26.54+7.17, 160.59+12.43, 58.22+1.231 and 22.18 +3.68, respectively. Frequency of pectoralis minor muscle tightness was 26.8%.
Conclusion: There is low frequency of pectoralis minor muscle tightness among individuals with asymptomatic shoulder.
