Auditory-motor Coupling in Multiple Sclerosis With Cerebellar Lesions

Study Overview
=================
Brief Summary
-----------------
This study is a case-control observational study, involving persons with multiple sclerosis and healthy controls. The study contains 1 descriptive and 4 experimental sessions. In the descriptive session, participant's clinical motor and cognitive functions are collected. In the first experimental session, participant's beat perception and synchronisation abilities is examined within a finger tapping paradigm. In the following experimental sessions participants synchronsiation abilities is examined during walking paradigms, to music and metronomes, at different tempi and alignment strategies. In the latter three sessions, apart from outcome measures of synchronization the following will be collected as well: spatio-temporal gait parameters, perceived fatigue, perceived motivation and perceived speed of walking.
