Filter by:Researchers at the University of Maryland Rehabilitation and Orthopaedic Institute are looking for individuals who have suffered a stroke and have leg and ankle weakness (foot-drop), to participate in a pilot study to examine the safety and effectiveness of an ankle robot walking program on walking function This is the first in human test of walking training over-ground using a wearable, lightweight, battery operated ankle robot exoskeleton; with assistance by trained research personnel for safety. This exercise device is aimed at assisting the foot during walking to reduce foot drop and improve walking safety in chronic, mild to moderately impaired stroke survivors who have foot drop. Possible risks of participating in this study are described in this document. The greatest risks include the risk of falling, muscle soreness, skin irritation, or cardiovascular complications. Before starting, you will have a medical history and medical assessments performed to determine if this study is safe for you. All sessions will be assisted by trained research personnel under supervision of a physical therapist, with medical personnel locally on call.
This study aims to assess whether the NeuroLutions Upper Extremity Rehabilitation System (known as IpsiHand) will help stroke patients regain strength and functional movements in their arm. The IpsiHand system involves using a hand robotic device that is controlled by brain waves, known as a Brain-Computer Interface (BCI). By using the device, participants will be harnessing brainwaves from the side of their brain not affected by stroke to control the robotic device on the hand that is weaker from the stroke.
Objective: The goal of this study is to implement and test a neuro-mechanical gait assist (NMGA) device to correct walking characterized by muscle weakness, incoordination or excessive tone in Veterans with hemiparesis after stroke that adversely affects their ability to walk, exercise, perform activities of daily living, and participate fully in personal, professional and social roles. Research Plan: A prototype NMGA device will be used to develop a finite state controller (FSC) to coordinate each user's volitional effort with surface muscle stimulation and motorized knee assistance as needed. Brace mounted sensors will be used to develop a gait event detector (GED) which will serve the FSC to advance through the phases of gait or stair climbing. In addition, a rule-base intent detection algorithm will be developed using brace mounted sensors and user interface input to select among various functions including walking, stairs climbing, sit-to-stand and stand-to-sit maneuvers. The FSC controller tuning and intent algorithm development and evaluation will be on pilot subjects with difficulty walking after stroke. Outcome measures during development will provide specifications for a new prototype NMGA design which will be evaluated on pilot subjects to test the hypothesis that the NMGA improves walking speed, distance and energy consumption of walking. These baseline data and device will be used to design a follow-up clinical trial to measure orthotic impact of NMGA on mobility in activities of daily living at home and community. Methodology: After meeting inclusion criteria, pilot subjects will undergo baseline gait evaluation with EMG activities of knee flexors and extensors, ankle plantar and dorsiflexors and isokinetic knee strength and passive resistance. They will be fitted with a NMGA combining a knee-ankle-foot-orthosis with a motorized knee joint and surface neuromuscular stimulation of plantar- and dorsi- flexors, vasti and rectus femoris. Brace mounted sensor data will be used for gait event detector (GED) algorithm development and evaluation. The GED will serve the FSC to proceed through phases of gait based on supervisory rule-based user intent recognition algorithm detected by brace mounted sensors and user input interface. The FSC will coordinate feed-forward control of tuned stimulation patterns and closed-loop controlled knee power assist as needed to control foot clearance during swing and stability of the knee during stance. Based on data attained during controller development and evaluation, a new prototype NMGA will be design, constructed and evaluated on pilot subjects to test the hypothesis that a NMGA device improves safety and stability, increases walking speed and distance and minimizes user effort. Clinical Significance: The anticipated outcome is improved gait stability with improved swing knee flexion, thus, increasing the safety and preventing injurious falls of ambulatory individuals with hemiplegia due to stroke found in large and ever-increasing numbers in the aging Veteran population. Correcting gait should lead to improved quality of life and participation.
The purpose of this study is to investigate if two courses of five consecutive sessions of noninvasive spinal stimulation paired with peripheral nerve stimulation at the forearm provided by an investigational device (Doublestim™/ MyoRegulator™ System - PathMaker Neurosystems Inc.) are able to improve wrist stiffness and motor function, when combined with intensive robotic wrist training program in participants with chronic spastic hemiparesis after stroke.
The objective of this pilot randomized controlled single blinded, parallel-group study is to detect change of the Action Observation (AO) and Repetitive Task Practice (RTP) combined practice schedule on upper limb motor impairment outcomes in chronic, moderately impaired stroke survivors.
This research project will investigate neurofeedback training in stroke rehabilitation during which patients receive feedback in real time from their brain activity measured with ElectroEncephaloGraphy (EEG). The investigators hypothesize that the feedback training allows to internally stimulate brain motor networks in order to promote functional recovery of the hand.
A multi-site, interventional, non-comparative, single-arm trial to evaluate the safety of the Keeogo™ Dermoskeleton in subjects with hemiparesis due to ischemic or hemorrhagic stroke.
The overall objective of the proposed study is to carry out usability and design-evaluation assessments of the BURT robotic device for delivering long-term intervention in stroke survivors. The BURT is an upper extremity robotic device that enables the user to see and feel engaging games that encourage intensive therapy. The investigators intend to recruit up to 10 stroke survivors over the course of the study. Participants will train their arm with the BURT for 18 sessions over approximately 6 weeks then participate in a question/answer formatted discussion with research staff to discuss the usability of the device. The investigators will also assess participant's arm function at baseline and after the training sessions.
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).
