Correlation between the Hand Grip Strength and the Shoulder Rotator Cuff Function
Keywords:hand grip, lateral rotator strength, rotator cuff, shoulder, hydraulic hand held dynamometer
Aim of the Study: To know if there is correlation between handgrip strength and shoulder rotator cuff
Materials and Method: total of 60 healthy, male volunteers with no history of shoulder, upper limb or neck
injury comprised the study group. The mean (SD) age was 20 ± 0.64 years (range 20 years to 25 years).
Grip strength (measured with hand grip dynamometer) and lateral rotator strength (measured with Manual
Muscle Testing) was measured at neutral, 90abduction, and 90abduction with 90external rotation.
Results: The correlation test reviled that there is significant correlation between handgrip strength and lateral
rotator cuff function in neutral and 90? abduction and lateral rotation. While it showed negative correlation
between in 90? abduction position.
Conclusion: This cross-sectional study concluded that there is positive correlation between neutral and 90?
abduction and negative correlation in 90? abduction position.
