INTRODUCTION
A depth-ranging sensor (Kinect) based upper extremity motion analysis system was applied to determine the spectrum of reachable workspace encountered in facioscapulohumeral muscular dystrophy (FSHD).
METHODS
Reachable workspaces were obtained from 22 individuals with FSHD and 24 age- and height-matched healthy controls. To allow comparison, total and quadrant reachable workspace relative surface areas (RSAs) were obtained by normalizing the acquired reachable workspace by each individual's arm length.
RESULTS
Significantly contracted reachable workspace and reduced RSAs were noted for the FSHD cohort compared with controls (0.473 ± 0.188 vs. 0.747 ± 0.082; P < 0.0001). With worsening upper extremity function as categorized by the FSHD evaluation subscale II + III, the upper quadrant RSAs decreased progressively, while the lower quadrant RSAs were relatively preserved. There were no side-to-side differences in reachable workspace based on hand-dominance.
CONCLUSIONS
This study demonstrates the feasibility and potential of using an innovative Kinect-based reachable workspace outcome measure in FSHD.
引言
应用一种基于深度测距传感器（Kinect）的上肢运动分析系统，以确定面肩肱型肌营养不良症（FSHD）患者可触及工作空间的范围。
方法
获取了22例FSHD患者以及24例年龄和身高匹配的健康对照者的可触及工作空间。为便于比较，通过将获取的可触及工作空间除以个体的臂长，得出总可触及工作空间和象限可触及工作空间的相对表面积（RSA）。
结果
与对照组相比，FSHD队列的可触及工作空间明显缩小，RSA降低（0.473±0.188 vs. 0.747±0.082；P<0.0001）。根据FSHD评估子量表II+III分类，随着上肢功能恶化，上象限RSA逐渐降低，而下象限RSA相对保留。基于利手的可触及工作空间没有左右差异。
结论
本研究证明了在FSHD中使用基于Kinect的创新型可触及工作空间结果测量方法的可行性和潜力。
