This study examines longitudinal data of subjects initially examined in the early subacute period of recovery following a stroke with a test of reach to grasp (RTG) kinematics in an attempt to identify changes in movement patterns during the period of heightened neural recovery following a stroke. Subjects (n=8) were a convenience sample of persons with stroke that participated in an intervention trial. Baseline Upper Extremity Fugl Meyer Assessment (UEFMA) scores ranged between 31 and 52 and ages were between 49 and 83. The UEFMA and RTG test were collected prior to intervention, immediately after the intervention (approximately 18 days later post baseline) and one month after the intervention. RTG data for the uninvolved UE was collected at the one-month session. Subjects reached for objects placed on a table 10 cm from their sternums, picking them up and placing them on a target 30 cm from their acromioclavicular joints. Data was collected using an optical motion capture system. Active makers were placed on each fingertip, metacarpophalangeal, and proximal interphalangeal joint. Four additional passive markers were placed on the dorsum of the hand, the elbow, the shoulder, and the sternum. Subjects demonstrated statistically significant improvements in reaching duration, reaching trajectory smoothness, time after peak velocity and peak grip aperture. All of these measures correlated significantly with improvements in UEFMA. Clinical Relevance- Kinematic measures of reaching and grasping collected early in the subacute period of recovery from stroke may offer insight into specific aspects of the recovery of upper extremity motor function that differ from the information gleaned from clinical scales.
本研究通过测试抓握（RTG）运动学，对中风后早期亚急性期恢复的受试者进行了纵向数据分析，试图确定中风后神经恢复高峰期期间运动模式的变化。受试者（n=8）是参加干预试验的中风患者的便利样本。基线上肢 Fugl Meyer 评估（UEFMA）评分在 31 到 52 之间，年龄在 49 到 83 之间。UEFMA 和 RTG 测试在干预前、干预后立即（约基线后 18 天）和干预后一个月收集。在一个月的会议上，收集了未受累 UE 的 RTG 数据。受试者伸手去拿胸骨前 10 厘米处放置的物体，将其拿起并放在肩峰前 30 厘米处的目标上。数据使用光学运动捕捉系统收集。在每个指尖、掌指和近节指间关节上放置主动标记。在手部背面、肘部、肩部和胸骨上放置了四个额外的被动标记。受试者在伸手持续时间、伸手轨迹平滑度、达到最大速度后的时间和最大握力开口方面都有统计学上的显著改善。所有这些措施都与 UEFMA 的改善显著相关。临床相关性-中风后恢复的亚急性期早期收集的伸手和抓握运动学测量可能提供了对上肢运动功能恢复的特定方面的深入了解，这些方面与临床量表得出的信息不同。
