The wrist is an essential component in performing the activities of daily living (ADLs) associated with a high quality of life. After a neurological disorder, motor function of the hand and wrist can be affected, reducing quality of life. Many experiments have illustrated that more wrist flexion/extension is required than radial/ulnar deviation when performing ADLs; however, how this result translates to efficiency in performing ADLs has not been investigated. Motivated by clinical assessment during neurorehabilitation, in this paper we investigate with able-bodied participants how performing tasks representative of the Jebsen-Taylor Hand Function Test are impacted when a splint constrains the user to a single rotational degree of freedom of the wrist. Twenty participants enrolled in the study, performing five tasks under five conditions, including constraint to pure flexion/extension and radial/ulnar deviation. The importance of wrist movement direction in performing ADLs efficiently found in this study could shape clinical wrist rehabilitation paradigms and wrist rehabilitation robot designs.
手腕是进行与高质量生活相关的日常生活活动（ADL）的重要组成部分。神经疾病后，手部和手腕的运动功能可能会受到影响，从而降低生活质量。许多实验表明，进行ADL时，手腕屈伸比桡偏/尺偏需要更多的活动；然而，这一结果如何转化为ADL执行效率尚未得到研究。受神经康复临床评估的启发，本文我们研究了在使用夹板将用户手腕限制在单一旋转自由度的情况下，健全参与者执行杰布森-泰勒手功能测试代表性任务时会受到怎样的影响。20名参与者参与了该研究，在五种条件下执行五项任务，包括限制为纯屈伸和桡偏/尺偏。本研究发现的手腕运动方向在高效执行ADL中的重要性，可能会塑造临床手腕康复模式和手腕康复机器人设计。
