Abstract
Power grip and pinch force are considered as important parameters of hand function. The aims of the present study were to compare the maximum hands strength of Taiwanese workers with the results from different countries and to establish the prediction models on the maximum muscle strength for different type of force exertion for Taiwan manufacturing workers.
One hundred and ninety-eight participants (99 males/99 females) were recruited to measure three different types of maximum strength (power grip, palmar pinch, lateral pinch). The participants were in five different groups (20–24, 25–34, 35–44, 45–54, 55–64).
Study results revealed that hand strength of power grip, lateral pinch and palmar pinch of right-hand exertion were 31.9 ± 12.6 kgw, 7.1 ± 2.2 kgw and 6.6 ± 2.0 kgw, respectively. Most of the maximum hands strengths of Taiwanese workers were smaller than those in Europeans and American. Using power grip force predict lateral pinch (Adjusted R2 = 0.717) and palmar pinch (Adjusted R2 = 0.609).
