Abstract
Background: Following a spinal cord injury, regaining hand function is a top priority. Current hand assessments are conducted in clinics, which may not fully represent real-world hand function. Grasp strategies used in the home environment are an important consideration when examining the impact of rehabilitation interventions.
Objective: The main objective of this study is to investigate the relationship between grasp use at home and clinical scores.
Method: We used a previously collected dataset in which 21 individuals with spinal cord injuries (SCI) recorded egocentric video while performing activities of daily living in their homes. We manually annotated 4432 hand-object interactions into power, precision, intermediate, and non-prehensile grasps. We examined the distributions of grasp types used and their relationships with clinical assessments.
Results: Moderate to strong correlations were obtained between reliance on power grasp and the Spinal Cord Independence Measure III (SCIM; P < .05), the upper extremity motor score (UEMS; P < .01), and the Graded Redefined Assessment of Strength Sensibility and Prehension (GRASSP) Prehension (P < .01) and Strength (P < .01). Negative correlations were observed between the proportion of non-prehensile grasping and SCIM (P < .05), UEMS (P < .05), and GRASSP Prehension (P < .01) and Strength (P < .01).
Conclusion: The types of grasp types used in naturalistic activities at home are related to upper limb impairment after cervical SCI. This study provides the first direct demonstration of the importance of hand grasp analysis in the home environment.
背景：脊髓损伤后，恢复手部功能是当务之急。目前的手部评估是在诊所进行的，可能不能完全代表现实世界的手部功能。在检查康复干预措施的影响时，在家庭环境中使用的掌握策略是一个重要的考虑因素。目的：本研究的主要目的是探讨家庭握把使用与临床评分的关系。方法：我们使用先前收集的数据集，其中21名脊髓损伤（SCI）患者在家中进行日常生活活动时录制了以自我为中心的视频。我们手动标注了4432个手-对象交互为功率、精度、中间和不可抓握。我们检查了使用的抓握类型的分布及其与临床评估的关系。结果：握力依赖与脊髓独立性测试ⅲ（SCI）之间存在中强相关；P P P P P P P P P P结论：家中自然活动中使用的握力类型与颈椎脊髓损伤后上肢损伤相关。本研究首次直接证明了在家庭环境中手抓分析的重要性。
期刊介绍：
Neurorehabilitation & Neural Repair (NNR) offers innovative and reliable reports relevant to functional recovery from neural injury and long term neurologic care. The journal''s unique focus is evidence-based basic and clinical practice and research. NNR deals with the management and fundamental mechanisms of functional recovery from conditions such as stroke, multiple sclerosis, Alzheimer''s disease, brain and spinal cord injuries, and peripheral nerve injuries.
