Implications of predicting hand proficiency from hand function tests and anthropometric measurements

Abstract

The successful performance of everyday activities depends largely on the ability to perform purposeful  movements efficiently and  precisely. These dextrous movements are known to be dependent upon finely-tuned successions of synergistic muscle activity. It is  possible to manipulate the environs with a high measure of hand motion suppleness using various tests. Hand function testing recognizes manual capability (dexterity), hand preference (handedness), hand performance (dominance), and grip strength (efficiency) as essential features of human control of motion. Although anthropometric measurements may be used to accurately  describe the characteristics of individual hands, the large variations reported between and within individuals and populations often present a challenge. In the  assessment of hand proficiency, the researcher needs to consider the usefulness of carrying out hand function tests in isolation vis-à-vis in combination one with  another. This should reveal the independence of the hand function tests and at the same time identify those which can be used to predict hand proficiency for a particular population and a specific function. The use of a combination of hand function testing would lead to a better understanding and determination of hand  proficiency. It would also allow for hand function to be fully  assessed and the interpretations of the tests would not be restricted. The findings of such research may be applied in making a better  placement of individuals in the work/training environment so that they perform tasks that put them at less risk for injury.
