本研究的目的是提供一个详细的空间和时间中断眼手协调时，使用假肢手在一个连续的精细运动技能。21名身体健全的参与者进行了15次试验的捡硬币任务来自南安普顿手评估程序与他们的解剖手和假肢模拟器，同时佩戴眼动跟踪设备。凝视行为结果显示，当使用假体时，性能改善伴随着显著更大的手聚焦凝视和显著更长的时间从操作中脱离凝视以计划即将到来的动作。研究结果强调了区分眼手协调中断的关键指标，这些指标可能对假肢使用培训产生影响。
The aim of this study was to provide a detailed account of the spatial and temporal disruptions to eye-hand coordination when using a prosthetic hand during a sequential fine motor skill. Twenty-one able-bodied participants performed 15 trials of the picking up coins task derived from the Southampton Hand Assessment Procedure with their anatomic hand and with a prosthesis simulator while wearing eye-tracking equipment. Gaze behavior results revealed that when using the prosthesis, performance detriments were accompanied by significantly greater hand-focused gaze and a significantly longer time to disengage gaze from manipulations to plan upcoming movements. The study findings highlight key metrics that distinguish disruptions to eye-hand coordination that may have implications for the training of prosthesis use.
