Kinect-based rapid movement therapy to improve balance in stroke survivors

M.Phil.Stroke survivors have higher risks of falling compared to healthy older adults. About 50-75% of individuals with stroke have fallen at least once within 6 months after discharge. With reduced limb control, postural stability and coordination, stroke survivors have impaired balance and increased fall risk. Faster response and movement time may be trained in chronic stroke survivors using a task-specific training to improve their balance recovery ability. Fast response time, being the task trained in addition to range of motion (ROM), is considered to be one of the most important motor training principles. The objective of this study is to investigate the effectiveness of interactive Rapid Movement Therapy (RMT) on balance compared to conventional balance training in individuals with chronic stroke. A total of 32 stroke survivors completed the assessor-blinded randomized clinical trial. All participants received twenty 1-hour sessions of either rapid movement therapy (RMT, n = 16) or conventional balanced training (CBT, n = 16). Assessments were performed before (PRE) and after (POST) the intervention, and also at 3-month follow-up. Berg Balance Score and Timed-Up and Go test were the primary outcome measure, while secondary outcome measures were composed of Activities Balance Confidence (ABC) Scale, Activities of Daily Living Scale (ADL), Fugl-Meyer Assessment (FMA) as well as “lean-and-release” fall assessment’s kinematic measures. Both RMT and CBT balance gave stroke survivors improvements in terms of overall balance performance, motor functioning, and fall risk as reflected in BBS, and FMA. We would like to investigate whether RMT could improve balance for stroke survivors. The results showed that the RMT has overall balance performance and motor functioning similar to the CBT. RMT could require less human resources with affordable technology.与健康的老年人相比，卒中患者摔倒的风险更高。大约50-75％的卒中患者在出院后6个月内至少会跌倒一次。随着肢体控制能力降低，姿势稳定性和协调性减弱，卒中患者的平衡能力受损，导致跌倒风险增加。通过特定任务的训练可以使慢性卒中患者锻炼更快的反应和运动时间，以提高他们平衡恢复的能力。快速响应时间，作为除ROM之外的任务训练，被认为是最重要的运动训练原则之一。本研究的目的是研究交互式快速运动训练（RMT）与卒中患者常规平衡训练的平衡效果比较。共有32名卒中患者完成了随机双盲临床试验。所有参与者都进行了20堂,时长为1小时的快速运动治疗（RMT，n = 16）或者常规平衡训练（CBT，n = 16）。功能评估分别在训练前（PRE）和训练后（POST）进行，并且在3个月后随访。 Berg平衡评分（BBS）和Timed-Up and Go测试为主要的评估手段，次要评估手段包括活动平衡信心（ABC）量表，日常生活活动（ADL）量表，Fugl-Meyer评估（FMA）以及“倚靠释放”跌倒评估的运动测量。从BBS和FMA评估结果来看，RMT和CBT两组平衡训练均可使卒中患者在整体平衡表现、运动功能和跌倒风险方面上得到改善。我们研究RMT是否可以改善卒中患者的平衡能力。结果显示，RMT在总体平衡性能和运动功能的改善上与CBT类似，但RMT可以减少人力开支獲得相同效果。Junata, Melisa.Thesis M.Phil.
