The objective of the current study was to measure (1) the Grip strength of type2 diabetes mellitus patients and (2) to find correlation of grip strength with duration of diabetes. Co-relational study design. Total of 280 subjects who fulfills the inclusion criteria participated in the study, out of which 140 subjects are known cases of recent or old type2 diabetes mellitus and 140 cases are normal subjects. Grip strength of normal subjects as well as diabetic subjects suffering with type2 diabetes mellitus was measured for both left and right hand with the help of a hydraulic hand dynamometer by a standardized procedure. Values of grip strength in normal as well as diabetic subjects were compared for differences between left and right hand using related t test. Differences of grip strength between diabetics and normal subjects, between males and females subjects were seen using independent t test, also correlation of grip strength with the duration of diabetes was calculated using Pearson product moment correlation. The results of the study showed normal subjects having more grip strength than diabetics in both males as well as females; also female subjects are having less grip strength than male subjects in both normal and diabetic subjects. Results of the study also show that right hand has more grip strength than left hand in both normal subjects as well as in diabetics for both males and females. Further it was seen that a week negative correlation exists between grip strength and the duration of diabetes i.e. as the duration of diabetes increases grip strength decreases.
