Abstract
Man moves his hands and arms to create things. These movements may be constructed as activities to change the environment favorably. Such movements result from coordinated control of the musculoskeletal system, by the hierarchical CNS. Man develops his working ability through learning; evaluation of the coordinated working ability of the highly advanced motor and sensory CNS in addition to the ability to conduct a series of simple movements may produce valuable results which could be helpful in evaluating finger working ability. The sensor pegboard test method was developed in this study. The upper-limb motions of the subjects, as they perform various specified tasks were measured and evaluated at the micromotion level (micromotion is defined here as the smallest motion element that can be distinguished with the sensor pegboard). This method can produce immediate results, which are not obtainable by conventoinal time and motion study methods, and can evauate many aspects of the capability of the upper-limb of workers. Using this method, the change in the upper-limb capability as a result of aging was quantitatively determined, and its overall picture was clarified.
