Brief Summary

Multiple sclerosis (MS) is a chronic neurological disease characterized by inflammation and degeneration within the central nervous system. Over the course of the disease, most patients with MS successively accumulate inflammatory lesions and axonal damage with an increasing degree of disability. Thus, pharmacological treatment options are currently adopted to limit inflammation and to decrease the relapse rate, or simply to alleviate symptoms. On the other hand, neurorehabilitation aims to maintain and possibly improve the residual capacities of neurological patients in order to preserve personal and social activities, constituting an important part of quality health care for MS patients. However, to date, there is no definite agreement on which specific exercise therapy program can be considered the most successful in improving activities and participation. Several studies suggest that a training based on voluntary movements produces greater improvements than a passive treatment. Aerobic exercise training has been also shown to have significant neurophysiological effects in different populations. Furtherly, sports activity may increase adherence and motivation, especially in a young population such as the MS community. However, feasibility of sports activity has not been investigated yet and, in general, the potential interest of these approaches for MS patients remains to determine.

This study aims at promoting physical activity in people with MS. Specific objectives are: (i) to evaluate the motor behavioral and neural changes induced by aerobic exercise combined with upper limb motor training based on task-oriented exercises; (ii) to assess the feasibility of leisure time physical activity (e.g. water sports activities) largely involving upper limb function.

Participants will receive task-oriented treatment, but only the experimental group will perform also aerobic training in order to evaluate the effect of aerobic exercise. Moreover, the role of sports activities will be preliminary investigated, by promoting the participation of the included patients to local or national events focusing on adapted aerobic sports specifically involving upper limb function (e.g., water sports such as sailing, windsurfing, canoeing). Clinical measures will be performed before and after interventions.

TUG-cog is a simple evaluative test used to measure functional mobility during dual-task performances

Change in the Modified Fatigue Impact Scale (MFIS) scoreBaseline (T0), after 5 days of sports activity (Ti, if applicable), after 8 weeks (T1), after 16 weeks (T2)

The MFIS is a patient reported outcome on the effects of fatigue in terms of physical, cognitive, and psychosocial functioning (Minimum value: 0; maximum value: 84; higher scores mean a worse outcome).

Change in the Dual-task Impact of Daily Activities Questionnaire (DIDA-Q) scoreBaseline (T0), after 5 days of sports activity (Ti, if applicable), after 8 weeks (T1), after 16 weeks (T2)

DIDA-Q is a self-report measure of the perceived difficulties of dual-tasking (Minimum value: 0; maximum value: 76; higher scores mean a worse outcome)

Structural and functional plasticity of the Central Nervous System (CNS)Baseline (T0), after 8 weeks (T1), after 16 weeks (T2)

Brain structure and function will be investigated using Magnetic Resonance Imaging (MRI) and Transcranial Magnetic Stimulations (TMS) in order to detect possible changes induced by the intervention.

MRI measures: axial single-shot spin-echo echo-planar diffusion tensor imaging (DTI) to obtain DTI-derived parametric maps (in particular, fractional anisotropy, axial diffusivity, radial diffusivity and mean diffusivity) TMS measures: motor evoked potential of 1mV at rest (S1mV) in the opponens pollicis (OP) before and after paired associative stimulation (PAS), a protocol known to induce a plastic increase of the primary motor cortex (M1) excitability. PAS consists of an electric stimulus delivered on the median nerve of the right arm 25ms (PAS 25) coupled with a magnetic stimulus administered on M1 in correspondence to the OP area. Two-hundred couples of stimuli will be administered to each participants for a total duration of 14 minutes.
