This study was to examine the kinematics, muscle activities, and perceived physical exertion in different regions of the spine during patient transfers by nursing students between a bed and a wheelchair, with or without a transfer belt in a laboratory setting. Results showed that with the effect of the belt, the % maximum voluntary contraction of the lumbar erector spinae was reduced significantly by nearly 10%. Muscle activity was significantly increased in thoracic erector and multifidus spinae during wheelchair-to-bed transfer, compared to bed-to-wheelchair transfers. There was no significant effect of belt or task on the spinal angular displacement in different spinal regions. Using the transfer belt was associated with a significantly decreased score for perceived exertion. In conclusion, this study supports the use of a transfer belt contributing to lower muscle activity and lower perceived physical exertion in the low back.
本研究旨在探讨护生在实验室环境中于病床与轮椅之间搬运患者时，使用或不使用转运带对脊柱不同区域的运动学、肌肉活动和感知体力消耗的影响。结果表明，在腰带的作用下，腰椎竖脊肌的最大自主收缩百分比减少了近 10%。与从轮椅转移到病床相比，在从病床转移到轮椅时，胸段竖脊肌和多裂肌的肌肉活动显著增加。腰带或任务对不同脊柱区域的脊柱角位移没有显著影响。使用转运带与感知用力的评分显著降低相关。总之，本研究支持使用转运带有助于降低腰部肌肉活动和感知体力消耗。
