Brief summary
The goal of this study is to develop and validate a haptic assistive method in order to support walking in patients with Parkinson's disease, delivered to the patient's hips through a wearable robotic pelvis orthosis.
Detailed description
None of the existing robotic devices used for gait rehabilitation in Parkinson's disease is wearable. Thanks to the wearable robotic pelvis orthosis we will use, the rehabilitation sessions can take place in an ecological environment. The other advantage of the proposed assistance protocol is its adaptability: patients will feel their hips pattern to be smoothed by the robot, but they will keep the freedom of continuously steering their main movement variables (like stride frequency, duration, and length). A key measured metric will precisely rely on this variability between stride durations. Indeed, the degree of stride-to-stride variability was shown to reflect the patient's physiological state, and to be correlated with the stage of the disease. Experimental trials will be conducted to assess both the assistive (i.e. the therapy effect during the therapy itself) and rehabilitative (i.e. effect after the therapy) natures of our protocol. The second main objective of this project will be the analysis of the effects of our protocol regarding the stride-to-stride variability of patients with Parkinson's disease.
Interventions
Walking with the robotic device providing the assistive protocol.
Walking exercises without wearing the robotic device.
