Brief Summary:
The upper limb (UL) plays an important role in the daily functioning of patients with Multiple Sclerosis (MS) and negatively influences their quality of life. Effective arm-hand training programs are needed. Various robotic systems have been developed for UL rehabilitation, mainly used in patients with stroke. Preliminary work in MS has focused on proximal sections of the arm. No study has evaluated the use of robotics for improving manual dexterity and their effects on cortical activity. The results of this research project could be relevant for the advancement of knowledge about UL functional recovery in individuals with MS and to determine the pattern of muscle activation underlying functional recovery.

Multiple Sclerosis Rehabilitation Device: Robot assisted treatment (Amadeo®) Other: Conventional treatment Not Applicable

Detailed Description:
Studies regarding the effectiveness of conventional and robot-based upper limb (UL) rehabilitation in individuals with MS is very limited.In the last 15 years, conventional rehabilitation of the UL in patients with neurological disorders has been enriched by the development of robots as they can provide high-intensity, repetitive, interactive and task-specific exercises.They are increasingly used in rehabilitation after stroke, therefore may also be good candidates for neuromotor rehabilitation of patients with MS. Furthermore, these devices can provide various feedbacks that can guide patients during the sensorimotor training and allow quantitative measurement of motor performance during training.One of these devices is the Amadeo®, a modern, mechatronic end-effector robotic device designed to improve sensorimotor functions in patients with restricted movement in individual fingers or in the entire hand.Another important issue concerns cortical plasticity, which plays a fundamental role in motor learning and neurorehabilitation.To date, the specific mechanisms leading to UL recovery after neurological rehabilitation are still unclear.The development of new EEG instruments allows brain activity to be tested under specific rehabilitation tasks contributes to give new insight in the dynamics of cortical networks reorganization promoted by rehabilitation.The main aim of the study is to perform a single blind RCT on 60 outpatients with MS (age:18-65 years;EDSS<8) in order to compare the efficacy of high-intensity robot-assisted training with conventional treatment on sensorimotor hand recovery, disability in ADLs and QoL.The secondary aim is to explore the underlying neuronal mechanisms of UL recovery by using EEG investigations and innovative robotic equipment. 10 controls (age 18-65 yrs) will undergo one session of the same Video-EEG acquisition to collect normative data to compare with data collected on patients.Each participant will receive 40-minute sessions over an 8 week period (3 days/week). Each session will consist of 30 minutes of hand training and 10 minutes of passive upper limbs mobilization.The experimental group will receive robot-assisted therapy by Amadeo.The control group will receive conventional rehabilitation.Before treatment, immediately after treatment, 1 month after treatment patients will be evaluated with a comprehensive protocol of all ICF domains as well as acquisition by Video-EEG acquisition combined with Amadeo® robotic training device.Primary outcome measures:Fugl-Meyer Assessment Motor Scale.Secondary measures: UL electromyographic analysis,Tremor Severity Scale, Nine Hole Peg Test, Amadeo® hand muscle strength (Newton), Motricity Index, Visual anolgue Scale for tiredness and fatigue; TEMPA, Motor Activity Log, Action Research Arm test, Multiple Sclerosis Quality of Life-54 and the assessment of Life Habits. Parametric tests and nonparametric tests will be performed according to variable distribution (p<.05)
