The effects of posture, duration, and force on pinching frequency
MG Klein, JE Fernandez - International Journal of Industrial Ergonomics, 1997 - Elsevier
A laboratory experiment was conducted utilizing the psychophysical approach to establish
the maximum acceptable frequency (MAF) for a pinching task. The type of pinch used was
the lateral pinch. The psychophysically adjusted pinching frequency was determined by the
method of adjustment for each of 18 combinations of wrist posture, force, and duration.
Twelve healthy males served as subjects. The results indicated that the MAF was
significantly reduced as the angle of wrist flexion, pinching force, and task duration …
