OCCUPATIONAL APPLICATIONSWhen compared to not using a soft-hand exoskeleton, the IronHand caused both increases and decreases in forearm muscle activity while completing automotive assembly tasks. Surprisingly, although there were reductions in muscle activity when wearing the IronHand, only a few of these decreases resulted in muscle activity changing such that they fell to below recommended ergonomic thresholds. Despite this, some individuals in our study clearly benefited from the device, and this suggests that there is potential for widespread use of such a device if fine tuned to the individual and task demands. Much work is still required for a design that will allow for optimal physical benefit.
职业应用
与不使用软手外骨骼相比，在完成汽车装配任务时，“铁手”导致前臂肌肉活动既有增加也有减少。令人惊讶的是，尽管佩戴“铁手”时肌肉活动有所减少，但只有少数这些减少导致肌肉活动变化到低于推荐的人体工程学阈值。尽管如此，我们研究中的一些个体显然从该设备中受益，这表明如果根据个体和任务需求进行微调，这种设备有广泛应用的潜力。要设计出能带来最佳身体益处的产品仍有许多工作要做。
