Effects of Training in Modifying Work Methods and Behaviors During Common Patient Handling Activities
MetadataShow full item record
This research investigated the effects of training (Video and Lecture/Practice) on modifying working behaviors and biomechanical stress. Two tasks were examined (wheelchair to bed and lift up in bed) with two types of assistance (one-person or two-person) and two levels of patient's dependence (semi-dependent or dependent). Changes in behaviors were examined immediately following training (1-2 days delay) and after a short period of time (4-6 weeks) and evaluated using the criteria of subjective ratings of exertion, and postural and biomechanical measures. Results indicated that training led to several significant changes in the knee, hip, elbow and torso angles, whole body, shoulders and low back RPE, shear forces and shoulder moments. No differences were observed in these measures after a short period of time, suggesting retention of the information presented during the training programs. Results as a whole suggest that training can positively affect the working postures and biomechanical stress during common patient handling tasks. All the postural changes and biomechanical measures were advantageous in terms of reducing musculoskeletal stress. It was also found that after a short period of time (4-6 weeks) still retained the information presented during the training programs. Training using a combination of lecture and practice in some cases achieved better results than Video-based training.
