|---|---|
| To evaluate, through surface electromyography, the immediate effects of using wrist orthosis on muscle coordination and magnitude, as well as on the variability of these values, of the myoelectric activity of biceps brachii, triceps brachii, anterior deltoid, middle deltoid, posterior deltoid, upper trapezius, middle trapezius, lower trapezius, latissimus dorsi, pectoralis major, serratus anterior and infraspinatus muscles when a person holds or not holds an object in his hand, during the acceleration and the deceleration phases of the reach-to-grasp tasks described in the project, performed wearing and without wearing the wrist orthosis.;To evaluate the immediate effects of using the wrist orthosis on the three-dimensional kinematics of the upper extremity (angles and angular variability - scapulo-thoracic, glenohumeral, elbow and wrist joints) when a person holds or not holds an object in the hand, during the acceleration and the deceleration phases of the reach-to-grasp tasks described in the project, performed wearing and without wearing the wrist orthosis. ;To evaluate, through end-point kinematics, the immediate effects of using the wrist orthosis on the spatio-temporal parameters of the hand's trajectory in the space with and without holding an object in the hand (displacement, velocity and acceleration), during the acceleration and the deceleration phases of the reach-to-grasp tasks described in the project, performed wearing and without wearing the wrist orthosis.;To evaluate if changes in the end-point kinematics, three-dimensional kinematics, muscle coordination and myoelectrical activity caused by the immediate use of the wrist orthosis are related to the phases of acceleration and deceleration of the movement when the person is holding and when the person is not holding an object in the hand, performed wearing and not wearing the wrist orthosis. ;To evaluate the immediate effects of using the writ orthosis on inter-articular coordination in the phases o | — |

| To evaluate, through the DASH questionnaire, the effect of wearing the wrist orthosis for 7 days on the functionality of the upper extremity during the performance of the tasks described in the experimental procedure. It is expected to find a greater score after 4 and 7 days of wearing the orthosis compared to the score obtained after 7 days of washout. The baseline DASH score is also expected to be equal the score after 7 days of washout.;To evaluate, through the DASH questionnaire, the immediate effect of using the wrist orthosis on the functionality of the upper extremity during the performance of the tasks described in the experimental procedure. It is expected to have a greater score when the person wear the orthosis to perform the tasks compared to when the person is performing the tasks without wearing the wrist orthosis. | — |
