Introduction: Grip strength is commonly used to evaluate the integrated performance of muscles by determining maximal grip force that can be produced in one muscular contraction. Purpose: The purpose of the study was to determine the effect of different shoulder positions on grip strength measurement in healthy individuals. Sample: 50 healthy subjects were included (19 males 31 females).

Methods: Grip strength in 5 different position of shoulder flexion with elbow extension was measure with the help of Jamar dynamometer.

Data analysis: Repeated measure ANOVA and post hoc analysis was done (α=5%, p=.05).

Results: The mean grip strength in 0° flexion (64.6±2.86 lb/inch2), 45° flexion (63.82±2.92 lb/inch2), 90° flexion (66.86±3.06 lb/inch2), 135° flexion (66.17±3.05 lb/inch2) and 180° flexion (67.82±2.92 lb/ inch2). Repeated measure ANOVA showed significant differences for grip strength in 5 positions (p=.0001). Post hoc comparison by bonferroni showed that there is significant difference between 0° versus 180° (p=.048), 45° versus 90° (p=.0001), 45° versus 180° (p=.0001).

Conclusion: The study concluded that shoulder has an effect on grip strength and maximum grip strength can be obtained in 180° of shoulder flexion with elbow extension
