1. The ability of eleven normal subjects to match the position of the proximal interphalangeal joints was tested. The right index finger (target finger) was moved to a given position and the subject was required to match this with the left index finger (matching finger). 2. Digital nerve block of the matching finger resulted in substantial impairment in(More)
Position matching at the proximal interphalangeal joint of the index finger in human subjects was tested by passive displacement of the right (target) finger and active matching of the left index finger. In 5 subjects it was found that position matching was grossly impaired after digital nerve block of the matching finger. Typically, subjects hyperextended(More)
This study proposed to determine the extent to which multiple gait trials provide further information than that obtained from a single trial of walking. Gait data were collected using a video camera and force platform system on 10 subjects including a below knee amputee. The data supported several conclusions. If the purpose of gait research is to(More)
The present review is concerned with the effects of noise, especially moderate intensity noise on performance. The review covers recent empirical results and theoretical approaches, and examines the importance of the nature of the noise, individual differences in response to noise, and other factors which modify the effects of noise. A central theme of the(More)
1. Proprioceptive acuity was tested at the proximal interphalangeal joint of the index finger of normal subjects. 2. Examination of the ability of the subjects to match finger positions (position matching procedure) revealed that digital nerve block (DNB) of the finger resulted in characteristic alignment errors at the extremes in all subjects. 3. When one(More)
