Abstract:
A muscle force transducer was developed as a research tool to detect and quantify tremors in divers working under hyperbaric conditions. The tremor device measures micortremor superimposed upon a neuromuscular response maintained within a specific force band. It incorporates a simple motor skill task, which requires the diver subject to maintain, for a predetermined number of seconds, a constant downward pressure with the tip of the middle finger upon a lever which is preset to a specific force. Variations in the subjects ability to maintain the zero reading are considered tremor. Measurement of tremor against an established baseline of an individual diver can provide an indication of neurological change, which may interfere with underwater work performance. Author
