Summary

This project will study the feasibility of motor rehabilitation in people with cerebellar ataxia using real-time functional magnetic resonance imaging neurofeedback (rt-fMRI NF) in conjunction with motor imagery. To do so, data will be collected from healthy adults in this protocol, to be compared with data from cerebellar ataxia participants.

Conditions

• Healthy

Interventions

Type	Name	Description
DEVICE	Neurofeedback treatment	During the fMRI scan, the tasks consist of: 1. Overt finger tapping in time with a flashing cue. 2. Motor imagery (of finger tapping). During overt finger tapping, feedback will consist of a slider bar that indicates tapping accuracy to target speed (1 or 4Hz). During motor imagery, neurofeedback will consist of a slider bar that indicates the success of recruiting predicted brain regions (consistent with those engaged during overt tapping).
BEHAVIORAL	At-home therapy	Participants are assigned to groups where they will practice each day for 3 weeks at-home. 1. Group 1: Imagery only. 2. Group 2: Overt finger tapping only. 3. Group 3: Imagery plus overt finger tapping. During imagery, participants will view the task while imagining that they are finger tapping in time with the flashing cue, using the imagery strategies identified during their previous neurofeedback session. During overt tapping, participants will finger tap in time with the flashing cue. A final assessment of overt tapping will be performed the day after therapy ends.
