Clinical Trial Summary

This study will compare bilateral priming followed by task specific training to health care education followed by the same task specific training protocol. The intention is to understand the effects of priming on upper limb training post-stroke.

Description:

Techniques to enhance use dependent plasticity have been examined in stroke rehabilitation research. The purpose of these techniques is to prime the cortex prior to training. The priming techniques previously described in the literature include medication (i.e. amphetamines), transcranial electric or magnetic stimulation, and manipulation of somatosensory input. Here, the investigators examine a priming technique which is non-invasive and free of side effects. The technique described in this study uses bilateral, symmetrical, rhythmic movement "bilateral priming" and its purpose is to ready the motor cortex for functional limb training. A "rocker" is used so that the less affected limb can drive the affected one in symmetrical wrist flexion and extension. In this project, the investigators intend to compare bilateral upper limb priming with task specfiic training to a health care education website program followed by the same task specific training as the experimental group.This active comparator (health care education) will receive stroke related health education via a website from the American Heart Association. Transcranial Magnetic Stimulation willl include measurement of transcallosal inhibition persistence from the affected hemisphere to the less affected hemisphere and vice versa ( less affected to affected). The investigators expect the bilateral priming group to have greater changes in transcranial magnetic stimulation measures and greater improvements in behavioral measures at all time points.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change Score of Chedoke Arm and Hand Activity Index Nine (CAHAI 9) Baseline to Follow-up (2 Timepoints)	The change score (Follow-up - Baseline) for the Chedoke Arm and Hand Activity Index 9 is reported. The change score scale ranges 0(min) to 63 (max). Higher scores indicate greater ability. Follow-up is at 6 weeks post treatment cessation. The scale measure bilateral activity performance.	value at 6 weeks minus value at baseline
Secondary	Change Score (Value at Follow-up - Value at Baseline) Fugl Meyer Upper Extremity Test of Function	Change score between 2-time points (6 weeks follow up - baseline) Change score scale: minimum is 0 and maximum is 66. Higher scores indicate better outcomes.	value at 6 weeks minus value at baseline
