The participant will be instructed how to execute static or the dynamic exercises while wearing the WPM-SEMG-V2 device. The WPM-SEMG-V2 device will be initially tested in a small number of healthy volunteers to evaluate the technical and clinical performance of the device in different settings (i.e., static and dynamic muscle contractions). Preliminary information gathered in the first part of the investigation may eventually guide further device modifications. The second part will capture preliminary clinical performance of the device in post-stroke patients. The main aim is to study the behaviour of the neuromuscular system in voluntary muscle activations and demonstrate the clinical relevance of the HD sEMG signals to support the process of rehabilitation of post-stroke subjects.
The goal of this clinical trial is to learn about the WPM-SEMG-V2 device (Wireless Portable and Multi-Channel, WPM) designated to acquire high-density (HD) surface electromyography (sEMG) signals in healthy volunteers and post-stroke patients. The main objectives are: 1) to technically and clinically validate the WPM-SEMG-V2 device in healthy volunteers; 2) to demonstrate the clinical relevance of the HD sEMG signals to support the process of rehabilitation of post-stroke patients. Participants will be asked to perform simple exercises using the muscles of the hand or the leg in static or dynamic contractions while wearing the WPM-SEMG-V2 device.
