Abstract : The goal of this research project is to answer the following questions: (1) does prior loading in terms of a full hand fatiguing load create a significant decrement with regard to a task requiring hand steadiness. If a decrement does exist, (2) what is the expected recovery period; and (3) can the decrement be related to the level of endurance to which the subjects were loaded. In an attempt to answer these questions, eight subjects were tested for level of hand tremor using a steadiness test. The subjects were tested before and after loading of the hand and an analysis was made of the resulting differences in performance levels. The following conclusions were drawn using the results of the study. Decrement in task performance requiring hand steadiness resulted from hand loading. The performance decrement was not prevalent after five seconds. The performance loss can be related to the endurance loading of the hand. (Modified author abstract)
