Assessment of hand power is very crucial for evaluating the functional outcome of any surgical procedure of upper limb. After performing any surgical procedure the most reliable method to evaluate the outcome is to compare the post- operative function with an already known set standard. The purpose of our study is to assess the power of prevailing and non-prevailing hand of adult Pakistani population. Material and Methods: 400 subjects (168 women and 232 men) were approached from the patients waiting area of different hospitals. Demographics, hand dominance and hand strength were recorded from every subject using a generic questionnaire. Results: 94% of the subjects were right-hand prevailing and 6% were left-hand prevailing. Hand grip strength of right hand was higher regardless of hand dominance and was significantly high in males than in females with the ratio 1. 7: 1. In both right- and left-hand prevailing groups, the prevailing hand was consistently stronger than the non-prevailing side. Comparing our results with the Malaysian study the grip strength of Pakistani population is 13% greater in males and 15% greater in females. However when comparing with the west, our grip strength was found to be 25% less than that of the western population. Conclusion: Statistics obtained from western or even Asian natives cannot be enforced to an equivalent Pakistani population. Regional standardizing statistics are crucial for allusion and serve as unbiased figures for desired rehabilitation. Demographics including profession, gender, age, hand dominance, weight and height must all be taken into an account when endowing normal values for grip strength.
