Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: High frequency rTMS
Each subject is provided with three different brain stimulation interventions in a single arm, single session crossover design study.
One of the sessions was 5 Hz rTMS
|
3 types of interventions on different sessions
peripheral sensory electrical stimulation and vibration of the stroke-affected hand administered concurrently with each rTMS
|
Other: Low frequency rTMS
Each subject is provided with three different brain stimulation interventions in a single arm, single session crossover design study.
One of the sessions was 1 Hz rTMS

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Two-point Discrimination
Time Frame: up to 1 hour after intervention
|
Baseline measure is collected immediately before the intervention. There are two data collections following each intervention, one datacollection is immediately after the intervention and the second one is at 1 hour after intervention. Two-point discrimination was measured with Disk-Criminator disks (Baltimore, MD) by determining the subjects' ability to perceive two points on the disk as two separate points rather than as a single point. The distances between the two points ranged between 2 and 15 mm. One and two sensory points were presented in a pseudo-random order to subjects' 4th digit volar fingertip surface. A threshold is determined when seventy percent accuracy is exhibited for identifying the difference between single versus double point stimulation. |
up to 1 hour after intervention

Change From Baseline in N20 Somatosensory Evoked Potential(SSEP) Peak Latency
Time Frame: up to 1 hour after intervention
|
Baseline measure is collected immediately before the intervention. Following each intervention, data is collected immediately after each intervention and at 1 hour after intervention. SEPs were recorded with a Cadwell Sierra Wave (Cadwell, Kennewick, WA) (LSCDVAMC) or with Powerlab 4/25T (AD Instruments Inc. Colorado Springs, CO) and a Grass Stimulator (Natus Neurology, Middleton, WI) (CC)44. The recording electrodes (1 cm diameter, gold cup electrodes filled with conductive paste) were placed 2 cm posterior to C3 & C4 (10-20 international system of EEG electrode placement) and the reference electrode at Fz (Figure 1). Stimulus was applied to the median nerve at the wrist. Ground electrodes were placed at the lateral epicondyle of the stimulated arm. The evoked response from 500 stimuli were recorded and averaged for a single trial. Three SEP trials were recorded then analyzed. Latencies (in milliseconds) were determined for N20. |
