Abstract
|
|
|
The purpose of this study was test utility of 10% rule in assessment of hand grasp strength. The 10% rule states that the dominant hand possesses a 10% greater grip strength than the non-dominant hand.
The subjects for this study consisted of 50 male 50 female college students who agreed participate in this study.
Grasp or grip strength was measured with a factory-calibrated hand dynamometer(Preston Co. production) for cylindrical grasp and JAMAR dynamometer for tip pinch strength.
Results showed an 14.60% strength of cylindrical grasp and 10.61% strength of tip pinch difference between dominant and non-dominant hands. Second showed that the 10% rule is valid for right handed person. except cylindrical strength of female and tip pinch strength of male.
Further research is necessary to determine the characteristics according to hand size and graspping time.
