RESUMEN
This pilot study investigated whether group training, in which participants become role models and coaches, would reduce discomfort as compared to a nontreatment Control Group. Sixteen experimental participants participated in 6 weekly 2-hr group sessions of a Healthy Computing program whereas 12 control participants received no training. None of the participants reported symptoms to their supervisors nor were they receiving medical treatment for repetitive strain injury prior to the program. The program included training in ergonomic principles, psychophysiological awareness and control, sEMG practice at the workstation, and coaching coworkers. Using two-tailed t tests to analyze the data, the Experimental Group reported (1) a significant overall reduction in most body symptoms as compared to the Control Group and (2) a significant increase in positive work-style habits, such as taking breaks at the computer, as compared to the Control Group. This study suggests that employees could possibly improve health and work style patterns based on a holistic training program delivered in a group format followed by individual practice.

This paper reviews the ergonomic and psychosocial factors that affect musculoskeletal disorders at the workstation. First is a model of a physiological assessment protocol that incorporated SEMG monitoring while working at the computer. Next is a study that showed that participants lack awareness of their muscle tension as compared to the actual SEMG levels. The final study illustrated how an intervention program can reduce RSI symptoms, decrease respiration rate, and lower SEMG activity. Recommendations include suggestions that successful safety and prevention programs need multiple components and that participants should to be trained to control physiological responses with respiration and SEMG biofeedback. All participants should master these physiological skills just as they learn how to use the computer.
