Conditions
Cerebellar Lesions

Other: Synchronisation abilities
Registration Number
NCT04887753
Lead Sponsor
Hasselt University
Brief Summary

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.

A Likert scale will be used, and participants will be asked to rate their perceived motivation of walking after each experimental walking conditions

Perceived cognitive and physical fatigueweek 3

A visual analogue scale will be used, and participants will be asked to rate their perceived cognitive and physical fatigue levels before and after each experimental walking conditions

Perceived walking speedweek 3

A Likert scale will be used, and participants will be asked to rate their perceived walking speed relative to their usual walking after each experimental walking conditions
