Brief Summary:
This is a multi-center, randomized, double-blind (patient and evaluator), sham-controlled study to be conducted in stroke patients with upper-extremity spasticity. The main objectives of this study are to evaluate the performance and safety of the MyoRegulator® device in active- versus sham-treated patients after 5 consecutive days of treatment. The MyoRegulator® device is a non-significant risk (NSR) investigational non-invasive neuromodulation device that uses multi-site direct current (multi-site DCS) stimulation for the treatment of muscle spasticity.
Detailed Description:
Stroke is the fifth leading cause of death in the U.S. and a leading cause of serious long-term disability. There are over 7.5 million patients in the U.S. living with stroke, and an estimated 795,000 additional cases of stroke occur annually in the U.S. Of these cases, approximately 610,000 represent initial attacks and 185,000 represent recurrent stroke according to the CDC.
Spasticity is a common finding in patients with stroke, arising in about 30% of stroke patients, and occurring usually within the first few days or weeks. It is a disorder of motor function that results from injury to the spinal cord or brain, and causes decreased motor performance as well as pain, discomfort and muscle weakness that greatly interferes with functional recovery. Spasticity can range from mild to severe and can cause striking impairments in functional movement.
An initial clinical trial of safety and feasibility suggests that five sessions of treatment with the MyoRegulator® device temporarily reduces spasticity and overall stiffness of the affected extremity with optimal reductions in spasticity occurring 2-3 weeks post stimulation intervention.
MyoRegulator® is a non-significant risk (NSR) investigational non-invasive neuromodulation device using multi-site direct current stimulation (multi-site DCS) for the treatment of spasticity. Multi-site DCS utilizes trans-spinal direct current stimulation (tsDCS) paired with transcutaneous peripheral direct current stimulation (pDCS). This study was designed to evaluate the efficacy and safety of MyoRegulator® in the treatment of post-stroke upper-limb spasticity.
The primary performance endpoint is defined as the reduction in wrist joint spasticity as measured using the Modified Ashworth Scale and will use a responder analysis. The study will be considered to have a successful outcome if a significant number of actively treated subjects respond to MyoRegulator® treatment as compared to the sham treated subjects following 5 days of treatment.
The primary safety endpoint is defined as the incidence of device-related serious adverse events. The safety of the device will be demonstrated if there are no incidents of serious adverse events caused or contributed to by the device treatment that are clinically unacceptable in light of the treatment benefits.
In order to evaluate the relationship between response to treatment and BDNF genotype, subjects will be asked to provide a saliva sample and give consent for BDNF genotyping.
