Abstract

Wearable sensors are increasingly applied to rehabilitation for arm movement analysis. However, simple and clinically relevant applications are scarce. To investigate the feasibility of single smart watch-based parameters for functional assessment in upper limb rehabilitation for musculoskeletal injuries using a commercial smart watch. Ten patients with unilateral shoulder pain and range-of-motion limitations were enrolled. They wore Galaxy Watch® and performed three sets of upper extremity tasks consisting of gross activities-of-daily-living tasks, Wolf Motor Function Test (WMFT), and Upper Extremity Functional Index (UEFI), and the acceleration and angular velocities were acquired. The motion segment size (MSS), representing motion smoothness from a clinical perspective, and various sensor-based parameters were extracted. The correlation between the parameters and clinical outcome measures were analyzed. The percent relative range (PRR) of the significant parameters was also calculated. For overhead and behind body activity task set, mean MSS for elbow flexion/extension axis significantly correlated with WMFT score (R = 0.784, p = .012). For planar tasks, mean MSS for the forearm supination/pronation (R = 0.815, p = .007) and shoulder rotation (R = 0.870, p = .002) axes significantly correlated with WMFT score. For forearm and fine movement task set, mean MSS of the elbow flexion/extension angle showed significant correlation with WMFT (R = 0.880, p < .001) and UEFI (R = 0.718, p = .019). The total performance time (R = −0.741, p = .014) also showed significant correlation with WMFT score. The PRR for mean MSS in forearm supination (71.5%, planar tasks) and mean MSS in x-direction (49.8%, forearm and fine motor movements) were similar to the PRR of WMFT (58.5%), suggesting sufficient variation range across different degree of impairments. The commercial smart watch-based parameters showed consistent potential for use in clinical functional assessments.

基于智能手表的肌肉骨骼损伤后上肢功能障碍评估：试点研究

可穿戴传感器越来越多地应用于手臂运动分析的康复治疗中。然而，简单且与临床相关的应用却很少。目的是研究在肌肉骨骼损伤的上肢康复中，使用商用智能手表对基于智能手表的单一参数进行功能评估的可行性。研究人员招募了 10 名患有单侧肩部疼痛和活动范围受限的患者。他们佩戴 Galaxy Watch® 执行了三组上肢任务，包括日常生活活动任务、沃尔夫运动功能测试（WMFT）和上肢功能指数（UEFI），并采集了加速度和角速度。从临床角度提取了代表运动平滑度的运动节段大小（MSS）以及各种基于传感器的参数。分析了这些参数与临床结果测量之间的相关性。还计算了重要参数的相对范围百分比（PRR）。在头顶和身后活动任务组中，肘关节屈/伸轴的平均 MSS 与 WMFT 分数显著相关（R = 0.784，p = 0.012）。在平面任务中，前臂上举/下垂轴（R = 0.815，p = .007）和肩部旋转轴（R = 0.870，p = .002）的平均 MSS 与 WMFT 分数明显相关。在前臂和精细动作任务组中，肘关节屈伸角度的平均 MSS 与 WMFT（R = 0.880，p < .001）和 UEFI（R = 0.718，p = .019）呈显著相关。总表现时间（R = -0.741，p = .014）与 WMFT 分数也有显著相关性。前臂上举的平均 MSS（71.5%，平面任务）和 X 方向的平均 MSS（49.8%，前臂和精细运动）的 PRR 与 WMFT 的 PRR（58.5%）相似，表明不同程度的障碍有足够的变化范围。基于商用智能手表的参数在临床功能评估中显示出一致的应用潜力。
