Abstract: An electrophysiological monitoring apparatus for designing a workstation (21, 21p). The monitoring apparatus preferably is a surface electromyography apparatus which includes pairs of electromyography electrodes sensors (31a, 31b; 32a, 32b; 33a, 33b) with appropriate grounding formed for attachment to a worker (24), a signal processor (37) connected to the electrodes and formed to process output signals from the electrodes and produce muscle loading profiles (101, 111, 121, 131) therefrom. The apparatus further includes a workstation (21, 21p) having an adjustable physical geometry capable of variation so as to change the manner of movement of the worker's muscles during performance of the task. The apparatus (21, 37) is used in a method to select a workstation configuration most desirable for extended use by the worker. The optimized overall workstation (21p) may be customized and used to train an individual worker (24) to lower his or her muscle loading profiles during performance of the task.
