: 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. Muscle Nerve 51 : 168–175, 2015
