Abstract

Purpose: The purpose of this study was to investigate the relationship between pull test and falls in the previous year in patients with Parkinson's disease over Hoehn & Yahr Stage three. Subjects: The participants were 24 patients with Parkinson's disease over Hoehn & Yahr stage 3. Methods: We investigated the relationship between pull test and falls, and determined the optimal cutoff point for prediction of people at high risk of fall from the receiver operating characteristic (ROC) curve. Results: The distribution of the pull test was significantly different between fallers and non-fallers. Using a cutoff score of 1, the pull test showed high sensitivity and specificity for identifying fallers (sensitivity: 94.7%, specificity: 60.0%). Conclusions: We suggest that the pull test with a cutoff score of 1 might be a useful tool for distinguishing people at high risk of fall in the patients with Parkinson's disease over Hoehn & Yahr Stage 3.
