COMPARATIVE STUDY OF MAXIMAL GRIP STRENGTH IN THE LEFT AND RIGHT HAND IN LEFT HANDED AND RIGHT HANDED INDIVIDUALS

Background and objectives: Maximal grip strength is an important parameter used during growth, aging, injury, rehabilitation, training or therapeutic trials. Handed ness shows difference in qualities of an individual. Our objective is to compare the value of maximal grip strength between left and right hand of left handed and right handed subjects. Materials and Method: With the use of Jamar dynamometer maximal grip strength is measured in 21 left handed and 78 right handed subjects with standard procedure. Results: In this study we found that when we compare the left and right hand on right handed subject, there is significant difference between values with dominant (right) hand having significantly higher maximal grip strength. But the difference is not significant in left handed subjects. Conclusion: From the study we can conclude that in right handed subjects right hand is significantly dominant than left hand, though further studies are required to establish the values.
