Introduction
Grip strength can be used in determining the effectiveness of the different
treatment strategies or procedures. Grip strength test provide and objective index of the
strength of the upper extremities. (Singapore Med J 2002 Vol. 43) Studies have
attempted to determine the differences in strength of left or right hand preference as well
as dominant or non-dominant preference. Crosby et. Al investigated normative values of
significant differences between dominant and non dominant hands. In their study, hand
grip strengths of the dominant hand were six percent higher than non dominant hand.
An experiment will be conducted to determine grip strength. The more upper

The averages for the participants in the
study showed that the non-dominant hand was 29.85kg, which was less than the results
for the dominant hand with 32.27kg. The data was broken down even further when
determining the difference between genders. The females within the group average for
the dominant hand was recorded as 26.61kg and the non-dominant hand results was
22.11kg. Male results differed in that they had a greater strength for the non-dominant
hand 43.75kg verses the dominant hand only measuring 41.38kg. In comparison with the
gender difference the female participants had a closer range of grip strength than the male
counterparts. The study also yielded results that the non dominant hand preference only
accounted for 5.8 percent of the overall hand dominance of the group.
The reasons for these results could be because men have bigger muscles than
women. The women that had higher grip strength probably work more highly demanding
jobs than the ones with very low grip strength results. The muscular build of a person
allow them to exert more strength while squeezing the dynamometer firing more
