Active clinical trials for "Stroke"

Many chronic stroke survivors have poor walking balance, contributing to an increased risk of falls and fear of falling. One factor contributing to these balance deficits is a reduced ability to place the feet appropriately when walking. This study investigates whether enhancing the sensory information available to chronic stroke survivors while they walk improves their foot placement accuracy and balance.

Whole body vibration (WBV) has been found to be useful in promoting bone health and muscle performance in older adults. To date, no study has examined the effects of different WBV frequencies on the properties of the muscle-bone unit in stroke patients. The overall aim of the proposed study is to compare the efficacy of different vibration frequencies on properties of the muscle function and bone turnover among people with chronic stroke. It is hypothesized that the higher-vibration frequency protocol will lead to significantly better outcomes related to the bone turnover and muscle function.

This trial studies the impact of motivational strategies designed by the gaming industry on adherence to a home tele-rehabilitation program designed to improve hand function in persons with stroke. A growing literature suggests that the extended practice of challenging hand tasks can produce measurable changes in hand function in persons with stroke. Current health care delivery systems do not support this volume of directly supervised rehabilitation, making it necessary for patients to perform a substantial amount of activity at home, unsupervised. Unfortunately, adherence to unsupervised home exercise regimens is quite poor in this population. The investigator's goal is to assess the impact of several well-established game design strategies: 1) Scaffolded increases in game difficulty 2) In-game rewards 3) Quests with enhanced narrative. The investigator's will utilize these enhancements to study their impact on motivation to perform a tele-rehabilitation- based home exercise program, adherence to the program and changes in hand function. The proposed study will utilize a system of novel rehabilitation technologies designed to facilitate home exercise performance. Subjects will perform 3 simulated rehabilitation activities supported by a passive exoskeleton, an infrared camera and software that will allow subjects to exercise at home. The investigator's will investigate: 1) Differences in measures of motivation elicited by motivationally enhanced simulations and un-enhanced control versions.2) The impact of motivational enhancements on actual adherence to a tele-rehabilitation program in persons with stroke and 3) The impact of motivational enhancement on improvements in hand function achieved by these subjects. This proposal will address a critical gap in modern rehabilitation - adherence to autonomous rehabilitation programs. Patient participation in unsupervised rehabilitation is one of the assumptions underpinning our health care system. This said, no data collected to date supports that adherence is acceptable. The technology and methodology in this proposal are an important step towards leveraging extensive research and development done by the computer gaming industry into improved rehabilitation practice.

prospective randomized double-blind sham-controlled study aimed to investigate the effects of Repeated Muscle Vibration (rMV) on motor recovery in acute stroke patients, treated within 72 hours from symptoms onset

Up to 40% of stroke survivors suffer from aphasia, making recovery of language abilities a top priority in stroke rehabilitation. Conventional speech and language therapy may have limited effectiveness. Leveraging multimodal data (behavioral, neuroimaging, and genetics), this study aims to 1) evaluate the efficacy of combining tDCS with speech therapy, 2) examine neural changes associated with recovery, 3) identify factors influencing response to treatment.

This study is to compare the effects of Interactive video balance-based exercise (IVBE) intervention and conventional rehabilitation on the balance and functional performance in stroke survivors. Fifteen participants will receive Interactive video balance-based exercise, while the other half will receive conventional rehabilitation.

The study enabled assessment of changes in body mass composition, metabolic syndrome and lipid profile in patients after stroke, following rehabilitation in hospital.

Currently, the guideline recommended re-perfusion such as intravenous thrombolysis and mechanical thrombectomy as the most effective treatment for acute ischemic stroke. However, the two methods are restricted by a strict time window, which greatly limits the number of the patients receiving treatment. The abundant studies have suggested that good collateral circulation can provide compensatory blood supply to save the ischemic penumbra and reduces the infarct volume, which improves the prognosis. How to improve collateral circulation in an efficient and safe way is a clinical challenge. Our recent experiment results of the animal and preliminary clinical experiments show that head-down position may significantly increase cerebral perfusion and improve neurological function. Clinically, head-down position is simple and easy to operate, and theoretically may increases brain perfusion and improve collateral circulation. A pilot randomized clinical trial is designed to investigate the effect of head-down position combined with routine rehabilitation in patients with ischemic stroke.The study is designed to explore the efficacy and safety of head-down position in patients with acute ischemic stroke

The intervention trial will examine the effectiveness and feasibility of integrating stroke survivors into an existing hospital-based cardiac rehabilitation program at Novant Health in Charlotte, NC. Stroke survivors will be recruited through hospital system providers and physical therapists (PTs) for entry into a multidisciplinary, three-month cardiac rehabilitation program. This program consists of three sessions per week of supervised cardiovascular endurance and strength training, stretching, relaxation and education. Participants will be stroke survivors, have completed formal physical and occupational rehabilitation (if applicable), and have treating provider approval.

This study seeks to explore the efficacy of several control mechanisms for the device and the impact of a device training program on its utility as a neuroprosthetic and training tool for upper limb recovery.
