Fast Arm Motor Skill Training in Chronic Stroke Survivors

Не применимо Завершено NCT05013762

Кратко

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.

Change in Arm Reaching Movement Time.

Change from baseline (assessed during the week preceding the intervention) to 3 days post-intervention, representing an average interval of 12 days · seconds

Change in Movement Smoothness

Change from baseline (assessed during the week preceding the intervention) to 3 days post-intervention, representing an average interval of 12 days · number of peaks

Change in Speed Accuracy Trade-off

Change from baseline (assessed during the week preceding the intervention) to 3 days post-intervention, representing an average interval of 12 days · Fitts' slope (sec/index of difficulty)
