The robotic assisted transfer device was developed as an updated lift technology to reduce adjustments in posture while increasing capabilities offered by transfer devices. The purpose of this study was to compare the trunk biomechanics of a robotic assisted transfer device and a mechanical floor lift in the transfer of a care recipient by a caregiver during essential transfer tasks.
Investigators enrolled 28 caregiver/care recipient dyads to complete 36 transferring tasks. Surface electromyography for the back muscles and motion data for trunk range of motion were collected for selected surfaces, phase, and direction tasks using a robotic assisted transfer device and a mechanical floor lift.
Robotic assisted transfer device transfers required significantly smaller range of trunk flexion (P < 0.001), lateral bend (P < 0.001), and axial rotation (P = 0.01), in addition to smaller distance covered (P < 0.001), average instantaneous velocity (P = 0.01), and acceleration (P < 0.001) compared with a mobile floor lift. The robotic assisted transfer device transfers required significantly smaller peak erector spinae (left: P = 0.001; right: P < 0.001) and latissimus dorsi (right: P < 0.001) and integrated erector spinae left (P = 0.001) and latissimus dorsi right (P = 0.01) electromyography signals compared with the floor lift.
The robotic assisted transfer device provides additional benefits to mobile floor lifts which, coupled with statistically lower flexion, extension, and rotation, may make them an appealing alternative intervention.
机器人辅助转移装置作为一种更新的提升技术被开发出来，以减少在调整姿势的同时增加转移设备提供的功能。本研究的目的是比较机器人辅助转移装置和机械地板升降机在护理人员进行基本转移任务时转移护理接受者时的躯干生物力学。
研究人员招募了 28 对护理人员/护理接受者，以完成 36 项转移任务。使用机器人辅助转移装置和机械地板升降机，对选定表面、相位和方向任务的背部肌肉进行表面肌电图和躯干活动范围的运动数据收集。
与移动地板升降机相比，机器人辅助转移装置转移需要的躯干前屈（P < 0.001）、侧屈（P < 0.001）和轴向旋转（P = 0.01）的范围明显较小，转移距离（P < 0.001）、平均瞬时速度（P = 0.01）和加速度（P < 0.001）也较小。与地板升降机相比，机器人辅助转移装置转移需要的竖脊肌（左侧：P = 0.001；右侧：P < 0.001）和背阔肌（右侧：P < 0.001）以及左侧竖脊肌（P = 0.001）和右侧背阔肌（P = 0.01）的集成肌电图信号明显较小。
机器人辅助转移装置为移动地板升降机提供了额外的好处，与统计上较低的屈伸和旋转相结合，可能使它们成为一种有吸引力的替代干预措施。
