Action Observation Treatment (AOT) is a rehabilitative strategy which has been proposed as a promising approach to improve motor performance in neurological conditions, including multiple sclerosis (MS).
In this clinical trial, the investigators aim to explore the role of a home-based AOT with virtual reality (VR) in improving upper limb motor function in people with MS (PwMS). The objectives are:
All participants will undergo treatment sessions for 3 weeks (5 consecutive days/week, total=15 sessions lasting 30 minutes each). Those in the VR-AOT group will observe, imagine and execute two upper limb motor tasks in each session. Those in the VR-LO group will perform the same tasks, but they will observe inanimate landscapes beforehand instead.

| Home-based Action Observation Treatment with virtual-reality for upper limb rehabilitation | Other | Observation of a VR scenario depicting multiple repetitions of a specific upper limb motor task belonging to typical activities of daily living, followed by mental imagination of the action observed and then by the execution of the same task, using objects provided in a kit. In each session, patients will watch 2 different videos and will perform the two corresponding actions. The time scheduled for observation, imagery and execution of each action will be of 5, 3, and 7 minutes, respectively, so that each session will last about 30 minutes. New actions, chosen from a dataset of 50 stimuli showing progressively increasing levels of difficulty, will be weekly administered on the basis of patient's degree of motor impairment, to involve different manual skills. 30 minutes sessions, 5 times a week for 3 consecutive weeks (15 sessions in total). |

This is a randomized, controlled, single-blinded, parallel study. A total sample size of 60 PwMS is planned, with 30 participants randomly assigned to each of the treatment arms (ratio 1:1) through a computer-generated list managed by a physician external to the study.

| Home-based landscape observation with virtual-reality for upper limb rehabilitation | Other | Observation of virtually explorable landscapes followed by rest with eyes closed without focusing on any thought in particular and then execution of the same actions requested to VR-AOT-group. In each session, patients will explore 2 different landscapes and perform 2 different actions. The time scheduled for observation, rest and action execution will be of 5, 3, and 7 minutes, respectively, so that each session will last about 30 minutes.New actions, chosen from a dataset of 50 stimuli showing progressively increasing levels of difficulty, will be weekly administered on the basis of patient's degree of motor impairment, to involve different manual skills. 30 minutes sessions, 5 times a week for 3 consecutive weeks (15 sessions in total). |
