Psychophysical frequency and sustained exertion at varyng wrist postures for a drilling task / Robert J. Marley, Jeffrey E. Fernández

Sumario: Two laboratory experiments were conducted: first, to utilize the psychophysical approach to establish maximum acceptable frequency for a sheet metal drilling task and, second, to examine the effect of sustained, static exertion upon objective and subjective measures under similar task conditions. In both experiments, the wrist posture required by the task was varied. Twelve healthy females served as subjects. Results show that the psychophysically adjusted task frequency was significantly lower when wrist deviation was required, particularly flexion
