TMS and Exercise for Post-stroke Pain
Study Details
Study Description
Brief Summary
There are over 7 million people living with stroke in the United States. Per year, approximately 17,000 Veterans are admitted to the VA for acute stroke. Chronic pain after stroke can occur between 10-50% of stroke survivors. Post-stroke pain (PSP) can lead to further complications in a stroke survivor's recovery. Exercise has improved PSP and associated symptoms such as mobility, fatigue, and quality of life. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique using electromagnetic induction for cortical neurostimulation. The use of rTMS has been explored shown to be effective in treating chronic PSP but is limited in effect duration. Our proposal will test the hypothesis that rTMS is feasible and safe to be paired with exercise. Additionally, the investigators believe a complementary effect can develop to enhance the neurostimulation duration of rTMS.

Outcome Measures
Primary Outcome Measures
- Visual Analogue Scale for Pain [through study completion, an average of 12 weeks]
The visual analog scale (VAS) is a validated, subjective measure for pain. Scores are based on self-reported measures of symptoms that are recorded with a single handwritten mark placed at one point along the length of a 10-cm line that represents a continuum between the two ends of the scale-"no pain" on the left end (0 cm) of the scale and the "worst pain" on the right end of the scale (10 cm)
Other Outcome Measures
- modified Rankin Scale [through study completion, an average of 12 weeks]
Measures the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. Score Description: 0 No symptoms at all No significant disability despite symptoms; able to carry out all usual duties and activities Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance Moderate disability; requiring some help, but able to walk without assistance Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance Severe disability; bedridden, incontinent and requiring constant nursing care and attention Dead
