Stroke Clinical Trial - Heart-Brain Retraining for Stroke Rehabilitation

Status Completed

Clinical Trial Summary

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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
