Brief Summary

Relapsing-remitting multiple sclerosis (RRMS) is associated with changes of the corticospinal tract integrity, which is quantified by means of corticospinal plasticity. Several factors, such as exercise and interlimb coordination can influence such corticospinal plasticity. Previous work in healthy and in stroke participants showed that the greatest improvement of corticospinal plasticity occurred during in-phase bilateral arm exercises. Here, the investigators propose a concurrent multiple baseline design study which has the advantage to verify the cause-effect inference by the staggered duration through separate baseline phases. The proposed study includes five people with RRMS, who will follow an intervention protocol which includes in-phase bilateral movements of the upper limbs, adapted to different sports activities and to functional training. The aim of the study is to investigate the effects of in-phase bilateral exercises on corticospinal plasticity and on clinical measures, using transcranial magnetic stimulation and standardized clinical assessment. To meet quality standards, the present study has been designed and will be conducted according to the "What Works Clearinghouse" criteria for single case studies.

Outcome Measures

Primary Outcomes (1)

  • Corticospinal Plasticity

    The investigators will assess the corticospinal plasticity using single pulse Transcranial Magnetic Stimulation (TMS). Following TMS recommended guidelines concerning safety and experimental conditions, bilateral cortical excitability and bilateral central motor conduction time (CMCT) will be assessed. Using electromyography (EMG) signals, the investigators will analyze bilateral cortical excitability and bilateral CMCT to determine corticospinal plasticity. The resting motor threshold (rMT) and the Motor Evoked Potential (MEP) amplitude of Abductor Pollicis Brevis muscle will define cortical excitability, while the MEP latency will be used to calculate the CMCT. To ensure methodological consistency, the investigators will collect all data by performing the same methodological procedures for both conditions (i.e., cortical excitability and CMCT) bilaterally (one side per assessment), across participants and across all time points.

Study Arms (1)

In-phase bilateral RRMS Participants A-E

EXPERIMENTAL

The study follows a concurrent multiple baseline design across subjects, which involves five people with RRMS as five different case studies.

Behavioral: In-phase Bilateral Exercises of the upper limbs

Interventions

The intervention protocol consists of in-phase bilateral exercises for the upper limbs, which are adapted to different sport activities and to fitness functional exercises, organized in a circuit training. Specifically, each session will consist of 1-3 sets, consisting of 10-15 repetitions of 9 different exercises targeting large muscle groups of the upper limbs. The specific exercises will include sports activities of basic technical skills of basketball (e.g., different types of passing, catching and throwing the ball) and volleyball (e.g., different types of passing and receiving the ball), whereas the fitness exercises will include shoulder rows, shoulder lateral raises, elbow flexions, elbow extensions, using resistance elastic bands, as well as exercises with the patients' own body weight (e.g., pushups, TRX). The intervention phase for each participant will consist of 12 consecutive weeks, for 3 times per week, 30-60 minutes each session.
