This dataset has information about 30 subjects while they were performing four gait tasks. There are three groups: ten people with Parkinson's disease with Freezing of Gait history (GFOG+), ten people with Parkinson's disease without Freezing of Gait (GFOG-), and ten people without Parkinson's disease, the healthy subjects, for the control group (GC). They are age and sex matched. To collect data, inertial sensors (accelerometer and gyroscope) were used; they were coupled to three smartwatches that have a movement disturbance monitoring system. Data was collected during the OFF and ON medication states for the Parkinson's disease volunteers. The annotation is also accessible; it takes into account the task events and the FOG episodes.
