The Action Research Arm Test (ARAT) can provide subjective results due to the difficulty assessing abnormal patterns in stroke patients. The aim of this study was to identify joint impairments and compensatory grasping strategies in stroke patients with left (LH) and right (RH) hemiparesis. An experimental study was carried out with 12 patients six months after a stroke (three women and nine men, mean age: 65.2 ± 9.3 years), and 25 healthy subjects (14 women and 11 men, mean age: 40.2 ± 18.1 years. The subjects were evaluated during the performance of the ARAT using a data glove. Stroke patients with LH and RH showed significantly lower flexion angles in the MCP joints of the Index and Middle fingers than the Control group. However, RH patients showed larger flexion angles in the proximal interphalangeal (PIP) joints of the Index, Middle, Ring, and Little fingers. In contrast, LH patients showed larger flexion angles in the PIP joints of the Middle and Little fingers. Therefore, the results showed that RH and LH patients used compensatory strategies involving increased flexion at the PIP joints for decreased flexion in the MCP joints. The integration of a data glove during the performance of the ARAT allows the detection of finger joint impairments in stroke patients that are not visible from ARAT scores. Therefore, the results presented are of clinical relevance.
动作研究手臂测试（ARAT）可能会因为评估中风患者异常模式的困难而产生主观结果。本研究旨在识别左（LH）和右（RH）偏瘫中风患者的关节损伤和代偿抓握策略。一项实验研究共纳入了 12 名中风后 6 个月的患者（3 名女性和 9 名男性，平均年龄：65.2±9.3 岁）和 25 名健康受试者（14 名女性和 11 名男性，平均年龄：40.2±18.1 岁）。使用数据手套评估患者在执行 ARAT 时的表现。与对照组相比，LH 和 RH 中风患者的 Index 和 Middle 手指的 MCP 关节的屈曲角度明显较低。然而，RH 患者的 Index、Middle、Ring 和 Little 手指的 PIP 关节的屈曲角度较大。相比之下，LH 患者的 Middle 和 Little 手指的 PIP 关节的屈曲角度较大。因此，结果表明 RH 和 LH 患者使用代偿策略，即增加 PIP 关节的屈曲度来补偿 MCP 关节的屈曲度减小。在执行 ARAT 期间整合数据手套可以检测到中风患者在 ARAT 评分中无法看到的手指关节损伤。因此，所呈现的结果具有临床意义。
