Differences in gait and postural balance parameters between PD and healthy control groups.

The symbol * indicates a significant difference using t-test or U test (0.01 was used as the significance level). Due to similarity between conditions, only normal habitual gait and the eyes-open condition for the balance test are presented. Mean (SD) are presented. PD: Parkinson’s disease CI: confidence interval COG: center of gravity AP: anterior-posterior ML: medial-lateral RCI: reciprocal compensatory index OL: open-loop.
