The objective of this study is to determine the impact of vibratory feedback on the quality and intensity of a common motor rehabilitation task of the upper-arm (hand-to-mouth) in stroke patients. For that purpose the investigators use the SWORD system that combines 3D motion quantification wearable sensors and a vibratory module. The investigators hypothesize that vibratory stimuli during a motor rehabilitation task increase significantly the number of correct movements performed per unit of time. The design of the study is a cross-over randomized clinical trial. With the SWORD system in place each patient will perform the hand-to-mouth task twice (with vibratory feedback and without it), the order being random. The number of correct movements and other motor outcomes will be assessed continuously under both conditions.

Number of correct movements
Number of correct movements performed within the duration of each hand-to-mouth task.
Time frame: At the end of each hand-to-mouth task.
Total number of movements
Total number of correct and incorrect movements performed within the duration of each hand-to-mouth task.
Time frame: At the end of each hand-to-mouth task.
Range of motion in degrees
Average, standard deviation and variance of the range of motion, measured in degrees, of all the correct movements performed during the duration of each hand-to-mouth task.
Time frame: At the end of each hand-to-mouth task.
Time between correct movements in seconds
Average, standard deviation and variance of the time between correct movements, measured in seconds, of all the correct movements performed during the duration of each hand-to-mouth task.
Time frame: At the end of each hand-to-mouth task.
Cumulative amplitude of correct movements in degrees
Sum of the amplitudes of all correct movements performed within the duration of each hand-to-mouth task.
Time frame: At the end of each hand-to-mouth task
Cumulative amplitude of all movements performed in degrees
Sum of the amplitudes of all correct and incorrect movements performed within the duration of each hand-to-mouth task.
Time frame: At the end of each hand-to-mouth task.
Number of pause events during the task
Number of episodes during the execution of each hand-to-mouth task where the patient stopped doing movements and/or the time between correct movements exceeded the mean plus one standard deviation measured within the same hand-to-mouth task.
Time frame: At the end of each hand-to-mouth task
Fatigue
Assessment of fatigue by the patient through an analogic scale from 0 (no fatigue) to 4 (interruption due to fatigue).
Time frame: At the end of each hand-to-mouth task.
Pain
Assessment of pain by the patient through an analogic scale from 0 (no pain) to 4 (interruption due to pain).
Time frame: At the end of each hand-to-mouth task.
Number and type of other distresses
Recording and description of any kind of discomfort reported by the patient or detected through vital parameter and arterial oxygen saturation monitoring.
Time frame: At the end of each hand-to-mouth task.
