Introduction: The aim of research is to create a learning environment that enhances learning. The present study aims to investigate the impact of contextual interference on spatial accuracy and the re-planning of motor tasks in individuals with Parkinson's disease. Methods: This study is semi-experimental and employs a pre-test/post-test design. A total of 64 individuals with Parkinson's disease (mean age = 62.93 ± 3 years) were selected through convenient sampling and randomly assigned to four equal groups (16 participants each): high similarity-structured, low similarity-structured, high similarity-random, and low similarity-random. Participants completed 180 trials (12 blocks of 15 trials) for three sequential motor tasks. The execution errors of the motor patterns were calculated at all stages. In the acquisition phase, a two-way mixed ANOVA (contextual interference × sequence similarity × 11 acquisition blocks) was used; for the retention phases, a two-way ANOVA (contextual interference × sequence similarity × three phases) was conducted; and for transfer and re-planning, a two-way ANOVA (contextual interference × sequence similarity) was analyzed at the 0.05 level. Results: The results indicated that in the acquisition phase, the high similarity-structured group performed better, and the interaction effect of group and sequence similarity was not significant in the retention and transfer phases. In the re-planning phase, the high similarity-random group performed better. Conclusion: According to the hypothesis of random practice expansion, it enhances memory representation and leads to deeper processing in memory. [ABSTRACT FROM AUTHOR] |
