Of the 5.7 million stroke survivors in the United States, up to 80% exhibit significant weakness in one arm (called "hemiparesis"). This devastating impairment undermines performance of valued activities and quality of life. Although rehabilitation is commonly provided, conventional affected arm rehabilitative strategies have negative evidence, or no evidence, supporting their use. Thus, there remains a need for evidence-based rehabilitative strategies for arm hemiparesis. Newer rehabilitative approaches emphasize repetitive, task-specific practice (RTP) incorporating the affected arm. However, many of these promising regimens require participation in intensive therapies, and most are only efficacious on the least impaired patients. Thus, there remains a need for an efficacious, practical RTP technique to address moderate affected arm hemiparesis. To address the above shortfalls, one of the investigators team members piloted an innovative brace integrating electromyography (EMG) and robotics. In his case series, 8 stroke patients exhibiting moderate arm impairment successfully participated in RTP, with the brace (called the "Myomo") detecting and augmenting their movement attempts. Aided by the Myomo, participation in the RTP regimen reduced subjects' affected arm impairment and spasticity. The next logical step is to test Myomo + RTP efficacy using randomized controlled methods and an appropriate sample size.
Stroke is the leading cause of disability in the United States, producing motor impairments that compromise performance of valued activities. Hemiparesis (or weakness in one arm) is particularly disabling, is the primary impairment underlying stroke-related disability, and the most frequent impairment treated by therapists in the United States. This study will test efficacy of a promising technique in reducing arm disability and increasing function, thereby improving outcomes and health, reducing care costs, for community dwelling patients with stroke-induced hemiparesis.
The purpose of this study is to determine whether split belt or conventional treadmill training can be used to treat walking pattern deficits from stroke and to determine whether this improves gait asymmetry and metabolic efficiency.
The purpose of this study is to test an innovative, advanced FNS microstimulator technology developed by the Alfred Mann Foundation (Santa Clarita, CA) called, the Radio Frequency Microstimulation (RFM) Gait System that promises to provide FNS training for restoration of functional gait components in a manner at least as efficacious as current investigational FNS systems. The design features of the RFM Gait System are intended to address the problems with the current FNS systems. The RFM implant devices are small enough to be inserted using only a 5 mm incision[3]. Because both the electrode (anode and cathode) are contained within the microstimulator, there are no lead wires traversing the skin, joints, or torso/limb junctures. Individual RFMs can be inserted at the motor points and nerves of each of the paretic muscles in the involved limb and coordinated using radio frequency technology.
This is a pilot study of repetitive transcranial magnetic stimulation (rTMS) to test tolerance and efficacy in children who have hemiparesis from acquired or presumed perinatal stroke.
The primary objective of this proposal is to investigate the safety of use of transcranial Direct Current Stimulation (tDCS)in children with hemiparesis. The research question, "Is transcranial Direct Current Stimulation safe for use in children with congenital hemiparesis?" relates to two hypotheses: 1. tDCS will not produce a major adverse event, including seizure activity. 2. No change in paretic or nonparetic hand function or cognitive status will occur.
The purpose of this study is to examine if practicing joint movements using specially designed devices can help in the recovery of muscle function in the arm/hand after a stroke. Subjects may qualify for participation in this study because they had a stroke and have had difficulty using their affected arm/hand ever since.
The purpose of this study is to determine whether split belt training can be used to treat walking pattern deficits from stroke and to determine whether different schedules and types of long term training on a custom split belt treadmill are likely to change/improve walking symmetry.
The aim of this study was to investigate the effects of gait training on ground level, combining BWS and FES in people following chronic stroke.
