Gait cycle in Parkinson's disease and progressive supranuclear palsy : Results of assessment using three axis acceleration sensors

In Parkinson's disease (PD) and associated diseases, the walk rhythm is disturbed, which is known as freezing gait and small steppage gait. The ten meter gait test is commonly used for gait evaluation. It is difficult for this test to capture the walk rhythm objectively. A three axis acceleration sensor can calculate the time of a gait cycle. This device can analyze the walk rhythm simply and objectively. We conducted a conventional walk measurement and analysis of the variation index for the gait cycle using the acceleration sensor in PD and progressive supranuclear palsy (PSP). Subjects and methods
