Abstract:
PURPOSE: We wanted to investigate the grip and pinch strength of hands and establish the clinical normative data for Korean people. MATERIALS AND METHODS: A sample of 234 Korean males and 281 Korean females (age: 10 to 84) were tested. Grip strength and pinch strength were tested twice with 5 minute interval between tests. RESULTS: Generally, hand strength peaked at 30 to 39 of age for both males and females. The average grip strength was 48.8 kg for males and 28.23 kg for females and they were 11% stronger than 12 years before in both groups. Tip pinch strength peaked in the forties, but key pinch and tripod pinch peaked in the thirties. All the peak hand strength was obtained in the 30 to 39 age group of females. Among the pinch strengths, key pinch was the strongest. For the right-handed people, the grip and pinch strengths of the right hand were stronger than those of the left hand. However, for the left-handed people, the left hand was stronger than the right hand only for the tripod pinch (p<0.005). CONCLUSION: The hand strength of Koreans peaked in the 30 to 39 age group. Key pinch was the strongest among the three pinch strengths. Right-handed people have a stronger right hand than the left hand, but the left-handed people have almost the same hand strength in both hands, except for the tripod pinch.
