Heart-Brain Retraining: Forced Aerobic Exercise for Stroke Rehabilitation

The purpose of this study is to gain a better understanding of how different types of exercise can help people after a stroke. The investigators want to study if different types of exercise will improve the use of arm and hand function after a stroke.

Study Overview

Detailed Description

Stroke is the leading cause of disability in the United States with approximately 795,000 new or recurrent strokes per year. An estimated two thirds of patients post-stroke cannot incorporate the affected upper extremity (UE) into their activities of daily living. In addition, stroke survivors experience a 60% decrease in cardiovascular capacity, which contributed to disability and diminished quality of life. Developing rehabilitation techniques to optimize motor recovery while improving cardiovascular endurance would benefit the stroke population.

Animal studies using a forced exercise (FE) paradigm, in which the rodent is exercised on a motorized treadmill at a rate greater than its voluntary rate, indicate an endogenous increase in neurotrophic factors such as brain-derived neurotrophic factor (BDNF) and glial-derived neurotrophic factor (GDNF). These neurotrophic factors are thought to underlie neuroplasticity and motor learning. It is hypothesized that patients with stroke, due to decreased motor cortical output, cannot sustain high rates of voluntary exercise necessary to trigger the endogenous release of neurotrophic factors; therefore, forced-exercise is necessary to augment their voluntary efforts and will be superior to voluntary exercise in facilitating motor recovery. When coupled with repetitive task practice (RTP) of the UE, an effective form of UE rehabilitation, FE will prime the brain for neuroplasticity. We have developed a safe and effective method of delivering forced-exercise to Parkinson's disease (PD) patients (NIH R21HD056316). Clinical and imaging data with PD patients indicate forced-exercise, but not voluntary exercise, triggers a neurophysiologic response in the central nervous system resulting in global improvements in motor and non-motor functioning and increased cortical and subcortical activation. The aim of this project is to conduct a preliminary trial to compare the effects of forced to voluntary exercise when coupled with RTP in promoting the recovery of motor function in patients with stroke.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Wolf Motor Function Test (WMFT)
Time Frame: Baseline, End of Treatment (8 weeks); End of Treatment + 4 week (12 weeks)
This consists of 2 strength tasks and 15 timed tasks of both the affected UE and the unaffected UE. Total Functional Ability Score is reported, scores range from 0-75, with higher scores indicating a better outcome.
Baseline, End of Treatment (8 weeks); End of Treatment + 4 week (12 weeks)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The Fugl-Meyer Assessment (FMA)
Time Frame: Baseline, End of Treatment (8 weeks); End of Treatment + 4 week (12 weeks)
This is a 33 item assessment of post-stroke UE impairment. Total score is reported, scores range from 0-66, with higher scores indicating a better outcome.
Baseline, End of Treatment (8 weeks); End of Treatment + 4 week (12 weeks)

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
The Stroke Impact Scale (SIS)
Time Frame: Baseline, End of Treatment (8 weeks); End of Treatment + 4 week (12 weeks)
This is a self-reported questionnaire evaluating quality of life. Normalized Hand Function is reported, scores range from 0-100, with higher scores indicating a better outcome.
Baseline, End of Treatment (8 weeks); End of Treatment + 4 week (12 weeks)
