2.4.2. Instrumented Assessment
post-stroke
All persons post-stroke were asked to perform a 3D functional motor task, named the object placing task, with the paretic arm. This task simulated a typical activity of daily living and was recorded at both The experimental setup and equipment have been previously described in detail [Muscle activity was recorded using a wireless multichannel sEMG system (CometaWavePlus, Cometa s.r.l., Bareggio, Italy). Surface electrodes were placed according to the SENIAM (Surface Electromyography for the Non-Invasive Assessment of Muscles) specifications [The instants of initiation and termination of each repetition of the object pacing task were computed as the times at which the velocity of the hand marker exceeded or fell below a threshold of 5% of the maximum value [
