This study was designed to evaluate the grip and pinch strength differences between sides for the right and left handed population. Methods: The study included 128 right and 21 left hand dominant volunteers. Grip strength of the participants were measured by using a Jamar dynamometer. Pulp pinch strength measurements were performed by manual pinchmeter. Results: When the study group was totally evaluated, a statistically significant difference was found between the grip and pinch strengths of dominant and nondominant hands in favour of the dominant hand. For further information we grouped 149 participants as right and left handed and investigated the number of subjects with stronger nondominant hand for each group. The percentage of stronger nondominant hand grip was 10.93% and 33.33% for right and left handed groups respectively. The results were less significant for pinch strength with 28.12% and 28.57% for right and left handed subjects respectively. Conclusion: We concluded that the dominant hand is significantly stronger in right handed subjects but no such significant difference between sides could be documented for left handed people.

It is widely accepted that, grip and pinch strength measurements provide an objective index of the functional integrity of the upper extremity (1) . The Jamar dynamometer has been found to give the most accurate and acceptable measures of grip strength and pinchmeter is used to quantify the finger pinch strength (2-4) . Recent studies have attempted to provide a definitive picture of the difference between dominant and nondominant hand strengths. Crosby et al investigated normative values of hand grip, pulp and key pinch and claimed that the population as a whole demonstrated significant differences between the dominant and nondominant hands (5) In their study, hand grip and
