This study is a case-control study, involving persons with persons with cerebellar lesions and healthy controls. The study contains 1 descriptive and 3 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, with period and phase auditory manipulations. In the latter twp sessions, apart from outcome measures of synchronization the following will be collected as well: brain activity using EEG recordings, spatio-temporal gait parameters, perceived fatigue, perceived motivation and perceived speed of walking.
