Abstract

BACKGROUND

Reach-grasp movements are motor components commonly affected after stroke and directly related to the independence of these individuals. Evaluations of these activities can be performed using clinical instruments and assessed by detailed and costly kinematic analyses. The aim of this study was to develop an analysis of reach-grasp movements in post-stroke patients using a simple, inexpensive, and manageable instrument.

RESULTS

A Mann-Whitney test was used to compare paretic and non-paretic limb motor performance. A statistically significant difference was found between the variables of total time (p = 0.02) and speed to reach target 3 (p = 0.04) for task 1, while in task 2 significance was found only in the aspect of speed to reach target 2 (p = 0.04). The correlation between clinical tests and variables of tasks was then performed using Spearman's rank correlation coefficient. At task 1, when compared with the REACH instrument, the close target sub-item; there was a high positive correlation between the parameters of total time (p = 0.028), target velocity 3 (p = 0.028), and target acceleration 3 (p = 0.028). Another instrument that showed a high positive correlation with the target time 3 (p = 0.01) and target acceleration 3 (p = 0.028) variables was the Box and Block Test. When correlated, the data between the task 2 variables and clinical instruments did not present statistically significant data.

CONCLUSION

Our instrument-the Temporal Data Acquisition Instrument-TDAI-fulfilled the expected objectives and can be used as an option to evaluate the movements of reach and grasp of upper limb post-stroke, using an easy and fast application, without the need for calibration.

摘要

背景

伸手抓握动作是中风后常见的运动成分，与这些患者的独立性直接相关。这些活动的评估可以使用临床仪器进行，并通过详细和昂贵的运动学分析进行评估。本研究旨在开发一种使用简单、经济且易于管理的仪器对中风后患者的伸手抓握动作进行分析。

结果

采用曼-惠特尼检验比较患侧和非患侧肢体运动功能。在任务 1 中，总时间（p=0.02）和到达目标 3 的速度（p=0.04）两个变量之间存在统计学差异，而在任务 2 中，仅在到达目标 2 的速度方面具有统计学意义（p=0.04）。然后使用斯皮尔曼等级相关系数对临床测试和任务变量之间的相关性进行了分析。在任务 1 中，与 REACH 仪器相比，接近目标的子项目与总时间（p=0.028）、目标 3 的速度（p=0.028）和目标 3 的加速度（p=0.028）之间存在高度正相关。与目标 3 的时间（p=0.01）和目标 3 的加速度（p=0.028）变量高度正相关的另一个仪器是 Box and Block Test。在相关时，任务 2 变量与临床仪器之间的数据没有呈现出统计学意义。

结论

我们的仪器-时间数据采集仪器-TDAI 达到了预期的目标，并且可以用作评估中风后上肢伸手抓握运动的选项，使用简单快速的应用程序，无需校准。试验注册：特赖里健康科学学院伦理委员会-编号 2.625.609，于 2018 年 4 月 13 日批准；巴西临床试验注册中心-RBR-4995cr 于 2019 年 7 月 4 日批准（http://www.ensaiosclinicos.gov.br/rg/RBR-4995cr/）。
