Early evidence suggests the use of cognitive strategies has potential to improve skill performance in people living with the effects of stroke, but no specific protocol has been identified. This study aimed to explore the potential of using the Cognitive Orientation to daily Occupational Performance (CO-OP) protocol to improve the functional performance of adults with chronic stroke.
A single case experimental design study with two replications was conducted. Three community-dwelling participants were recruited. Each selected three functional goals for the focus of the CO-OP intervention. Multiple video recorded data points were collected at baseline, during intervention, post-intervention and at 1-month follow-up.
The nine goals selected varied widely, e.g. using a computer mouse, bicycling and yoga. An independent observer used the observational Performance Quality Rating Scale (PQRS) to rate performances throughout. Using the 2 SD band method to analyse the data, each participant showed significant performance improvements in at least two goals during the course of the intervention and at follow-up. Two participants had an additional goal show significant improvement at follow-up.
Results provide preliminary evidence that CO-OP is associated with significant performance improvements in self-selected functional goals.
早期证据表明，认知策略的使用有可能改善中风后遗症患者的技能表现，但尚未确定具体方案。本研究旨在探讨使用日常职业表现认知取向（CO-OP）方案改善慢性中风成人功能表现的潜力。
进行了一项有两次重复的单病例实验设计研究。招募了三名社区居住参与者。每人选择三个功能目标作为CO-OP干预的重点。在基线、干预期间、干预后和1个月随访时收集多个视频记录的数据点。
所选的九个目标差异很大，例如使用电脑鼠标、骑自行车和做瑜伽。一名独立观察者使用观察性表现质量评定量表（PQRS）对整个过程中的表现进行评分。使用2标准差带方法分析数据，每位参与者在干预过程中和随访期间至少在两个目标上表现出显著改善。两名参与者在随访时有另外一个目标表现出显著改善。
结果提供了初步证据，表明CO-OP与自我选择的功能目标的显著表现改善相关。
