The sequence effect (SE), defined as a reduction in amplitude of repetitive movements, is a common clinical feature of Parkinson's disease (PD), being a major contributor to freezing of gait (FOG). During walking, SE manifests as a step-by-step reduction in step length when approaching a turn or gait destination (dSE). The investigators studied the effect of a 4-week rehabilitation program on the destination sequence effect in patients affected by Parkinson's disease with and without Freezing of Gait. All subjects were evaluated with inertial gait analysis for dSE recording.
