Journal Article 2017 06 18 <strong>Introduction:</strong> The prevalence of Parkinson's disease in recent years, especially among elderly people, has increased. The aim of the present study was to determine the effect of 8 weeks of core stability training on intrinsic motivation in Parkinson's disease. <strong>Methods</strong>: This was an experimental and field research with pre- post-test method and control group. 20 patients with aged between 55 to 75 years were selected through purposive sampling with mild to moderate disease and were randomly divided to two experimental and control groups. Hohen & Yahr (H&Y) index for assessing the severity and stage of disease were used. The experimental group participated in 8 weeks and 3 sessions per week of core stability training. Before and after the training, the pre- and post-test of intrinsic motivation questionnaire (McAuley et all, 1989) was used to assess. The mixed ANOVA test with repetitive measures in last factor was used. <strong>Findings</strong>: The findings related to intrinsic motivation (and subscales) index in Parkinson's disease showed that statistically significant differences were found between the two groups in favor of experimental group, such a way that the experimental group had more motivation score than the control group. <strong>Conclusion</strong>: Probably in this study, increased mobility experiences and also improve strength leading to increased intrinsic motivation (interest and enjoyment, perceived competence, effort). <strong>Introduction:</strong> The prevalence of Parkinson's disease in recent years, especially among elderly people, has increased.
