• Description:
  Injuries of neck and shoulder significantly contribute to morbidity among healthcare workers. Working conditions for these occupations typically require exposure to physical and psychosocial demands. In this study, bed-to-stretcher patient transfer tasks were studied under the presence and absence of psychosocially stressful conditions. Surface electromyography data from three neck muscles were collected. This data was further processed and analyzed using the discrete wavelet transform (DWT) to quantify neuromuscular fatigue. The results showed that the power of the fatigue frequency band (12-23 Hz) was significantly affected presence of psychosocial stress; indicating that neck and shoulder muscles were more fatigued during combined physical and psychosocially stressful exertions than during physical exertions alone.
