Abstract
The purpose of this study was to compare the physiological stresses on nurses in two techniques to assist clients to sit up. Twelve female college students served as subject for this study. Each subject performed two different transfer techniques to assist client to sit up. One was traditional technique (A method), another was new technique according to body mechanics (B method). Oxygen uptake (VO2), heart rate, and myoelectric signals [left trapezius (TM), right biceps brachii (RB), left biceps brachii (LB), left rectus femoris (RF), and left erector spinae (ES)] were measured during performing the transfer technique.
VO2 and heart rate in A method were greater significantly (p<0.05) than those in B method. Integrated EMG (iEMG) of RB and ES in A method were greater significantly (p<0.001) than those in B method, while iEMG of RF in A method was lower (p<0.05) than that in B method.
These results suggest that physiological stresses in B method lower than A method. It was thought that the difference how to use the lower limb (RF) between both methods effects on the physiological stresses.
