Upper Limb Robot-Assisted Therapy in Patients with Guillain-Barré Syndrome

Patients will undergo 20 session of 45 minutes each with an exoskeleton for upper limb rehabilitation. The assistance provided by the device is adjusted based on the maximum force (as a percentage of the upper limb's weight) the robot needs to exert to assist the patient's movements. Each session will include exercises designed to improve the range of motion (ROM) of the shoulder, elbow, wrist, and enhance hand coordination. The training parameters, such as difficulty level, duration, and visual stimuli, will be adjusted based on the patient's residual abilities. The selected exercises may involve movements of a single joint along one axis, combined movements of a single joint around 2 or 3 axes, selective exercises for the opening and closing hand, or multi-joint exercises. All exercises will be realized with audiovisual feedback.

Patients will undergo 20 session of 45 minute of a neurorehabilitation intervention with a SHAM treatment under the guidance of the experimental therapist. This will involve passive mobilization using the exoskeleton for the upper limb, without any audiovisual feedback. They will not realize any active movement during the training.
