Fast Training Promotes Recovery of Arm Movements Post-stroke Via Cerebellar-mediated Anticipatory Feedforward Control
In Brief
A clinical study evaluating Fast intervention and Active Monitoring for Cerebrovascular Stroke. Completed, enrolled 44 participants across 1 site.
Detailed Summary
Every year, almost 800,000 people experience a stroke in the United States, which lead to upper-limb impairments, making recovery of motor function a priority in stroke rehabilitation. 1) The primary objective of this study is to determine whether fast arm movement training on a tracking task ("Speed-training"), in chronic stroke survivors with mild to moderate paresis, will generalize to improve arm function better than dose-equivalent accuracy training on the same task. 2) study the effect of intensive arm training on the recovery of anticipatory feedforward control. 3) Determine the involvement of cerebellar-cortical circuits in the recovery of arm movements due to speed training.

Timeline
Arms & Interventions
Participants will perform 400 complex movements per day over 4 days over a one-week period. The task requires participants to navigate their hand through a "track" projected on the surface of a table with a width of 5cm. Participants receive adaptive score based on their movement time. .
The accuracy-biased group receives a dose equivalent intervention with a emphasize on accuracy. The width of the track projected on the table is narrower (less than 2cm) and the adaptive score received are based on their accuracy to say within the boundary of the track.
Interventions
This intervention is based on recent body of evidence that high-speed movements during training are effective at improving arm movements in individuals with chronic stroke.Participants will be rewarded for movements performed within a short amount of time.
This is an observation-only group. The training received in this group will be dose equivalent to the active group.
