人类前瞻性实验研究。确定用于护理支持的混合辅助肢体（HAL）是否可以在患者转移期间减少腰椎负荷。护士中工作相关性腰痛（LBP）的患病率很高。特别是，转移患者由于腰椎负荷大而造成LBP的高风险。尝试减少腰椎负荷对于避免LBP的风险至关重要。因此，我们调查了HAL对护理支持的影响。19名志愿者（16名男性，3名女性）将一个60公斤重的娃娃从坐姿提升到站立姿势。第一次转移是在没有HAL for Care Support的情况下进行的，第二次转移是在HAL for Care Support辅助机器人的情况下进行的。我们评估了转移性能，视觉模拟量表（VAS）评分腰椎疲劳，躯干和髋关节的肌电图分析。四名参与者（两名男性，两名女性）成功地使用了HAL护理支持，即使他们没有HAL护理支持就无法执行任务。所有参与者的平均腰部疲劳VAS评分为62 mm，而没有HAL护理支持的参与者为43 mm。在HAL护理支持的腰部辅助下，转移过程中的主观腰部疲劳显著降低。功效分析表明，统计功效足以检测腰椎疲劳VAS评分的差异（0.99）。在使用HAL进行护理支持转移期间，仅左侧臀大肌的活动显著增加。在使用HAL for Care Support进行转移期间未发生不良事件。用于护理支持的HAL能够在模拟患者转移中减少腰椎负荷。
Prospective experimental study in humans. To determine whether the hybrid assistive limb (HAL) for Care Support can reduce lumbar load during a patient transfer. The prevalence of work-related low back pain (LBP) among nurses is high. In particular, transferring patients poses a high risk for LBP due to the large lumbar load. Attempts to reduce the lumbar load are crucial to avoid the risk of LBP. Therefore, we investigated the effects of the HAL for Care Support. Nineteen volunteers (16 men, three women) lifted a 60-kg doll from a seated position to a standing position. The first transfer was performed without the HAL for Care Support, and the second was performed with the HAL for Care Support assistive robot. We evaluated transfer performance, the visual analog scale (VAS) score for lumbar fatigue, and electromyogram analyses of the trunk and hip. Four participants (two men, two women) succeeded with the HAL for Care Support even though they were unable to perform the task without it. The mean lumbar fatigue VAS score for all participants without the HAL for Care Support was 62 mm, while that with it was 43 mm. With lumbar assistance from the HAL for Care Support, subjective lumbar fatigue during the transfer decreased significantly. A power analysis indicated adequate statistical power to detect a difference in the VAS score for lumbar fatigue (0.99). The activity of the left gluteus maximus alone increased significantly during transfers with the HAL for Care Support. No adverse events occurred during use of the HAL for Care Support for transfers. The HAL for Care Support was able to reduce lumbar load in a simulated patient transfer.
