The purpose of the research is to develop a new medical device prototype to restore functional movement of an arm made weak due to a chronic stroke
This is a Phase III clinical trial to compare the efficacy of two dosages of a new infant rehabilitation protocol - I-ACQUIRE - to usual and customary forms of infant rehabilitation in infants who experienced Perinatal Arterial Stroke (PAS).
This study is a necessary and important step in the development of a new therapy for upper limb functional recovery in patients with severe motor impairment. It is the first clinical trial of non-invasive brain stimulation (repetitive transcranial magnetic stimulation or rTMS) delivered to excite the undamaged hemisphere (specifically the contralesional higher motor cortices or cHMC) in stroke. Therefore, this study will determine whether the positive results obtained in our short-term pilot study can be made to last longer and produce functional benefits in severe patients with the application of brain stimulation in combination with long-term rehabilitation therapy. Rehabilitation therapy administered is called contralaterally controlled functional electrical stimulation (CCFES). Determining whether combining rTMS facilitating the cHMC with CCFES produces synergistic gains in functional abilities in severe patients is necessary for acceptance by the clinical community and to move this technology toward commercialization and widespread dissemination. The proposed study will determine whether the combination of rTMS facilitating the cHMC with CCFES produces greater improvements in upper extremity function in severe participants who are ≥6 months from stroke onset than the combination of rTMS facilitating the damaged hemisphere (specifically the ipsilesional primary motor cortex, iM1) and CCFES or the combination of sham rTMS and CCFES. The secondary purposes are to define which patients benefit most from the treatments, which may inform future device and treatment development and clinical translation, and to explore what distinct effects the three treatments have on the brain. To accomplish these purposes, we are conducting a clinical trial that enrolls severe stroke patients.
This study will evaluate the feasibility of dual tDCS to improve arm motor function in chronic stroke patients. In addition it will collect pilot data on the blood biomarkers associated with treatment effect.
The Take Off Pounds after Stroke (TOPS) trial is a Prospective Randomized Open-Label Blinded Endpoint (PROBE) study that will test a 12-week high protein, calorie restricted, partial meal replacement program, compared to enhanced standard care, for efficacy in achieving clinically significant weight loss without impairment of motor recovery in patients with elevated body mass index (BMI) and upper extremity weakness following a recent ischemic stroke.
The purpose of the study is to determine the effects of pairing gait training with different forms of visual feedback about leg movements in individual post-stroke to modify/normalize their gait pattern over time.
This is a feasibility study to alter the Microsoft Kinect software to be used as a rehabilitation tool. The prototype used is still in the early developing stage. The purpose of this research study is to develop a prototype of altered Microsoft Kinect Software and determine its use in improving the function of the study subjects' weaker extremities. The altered software will allow a viewing of the mirror image of the involved limb as it is moved. However, the image that is viewed will reflect normal movement even if the limb cannot move normally. By viewing normal movement of the weaker limbs the "mirror neuron" network in the brain will become activated and will ultimately improve the function of the weaker side.
This project is a continuing study from the FEATHERS project (NCT02290353) which focuses on developing novel home therapy program for persons with hemiparesis. This study will focus on examining motor behaviour and adaptation in neurodevelopmental hemiparesis (cerebral palsy, acquired brain injury (ABI)). New algorithms for motion control involved in encouraging active movement are developed and will be tested, but the study has the same therapeutic goal and focus as the original FEATHERS project of creating an engaging at-home bimanual upper limb training program. By incorporating existing gaming technology, we hope to discover novel ways to adapt commercial motion tracking controllers and visual feedback into engaging rehabilitative learning tools. This study will focus on a basic science aspect of human bimanual movements that can be incorporated into future applications of the full FEATHERS project devices. We believe that together these approaches will yield interventions that significantly improve functional ability and lead to improved quality of life.
Stroke is the leading cause of long-term disability in the U.S. Individuals with hemiparesis due to stroke often have difficulty bearing weight on their legs and transferring weight from one leg to the other. The ability to bear weight on the legs is important during functional movements such as rising from a chair, standing and walking. Diminished weight transfer contributes to asymmetries during walking which commonly leads to greater energy expenditure. Moreover, deficits in bearing weight on the paretic leg contribute to lateral instability and are associated with decreased walking speed and increased risk of falling in individuals post-stroke. These functional limitations affect community participation and life quality. Thus, restoring the ability to bear weight on the legs, i.e., limb loading, is a critical goal for rehabilitation post-stroke. The purpose of this research is to identify the impairments in neuromechanical mechanisms of limb loading and determine whether limb loading responses can be retrained by induced forced limb loading.
