Filter by:Impaired hand function is one of the most frequently persisting consequences of stroke. The purpose of this study is to compare two different treatments -- Contralataterally Controlled Functional Electrical Stimulation (CCFES) and Cyclic Neuromuscular Electrical Stimulation (cNMES) -- for improved recovery of hand function after stroke.
The investigators will study motor recovery after robot-assisted therapy after stroke. A small clinical trial will be conducted to quantify the central nervous system changes associated with robotic or standard training, and identify trends across high and low responders in terms of patterns of change in cortical activity and type of white matter connectivity.The investigators hypothesize that robot training will lead to larger improvements as compared to standard occupational therapy. The investigators hypothesize that high responders to the robot training will have reduced compensatory activation in the bilateral area and will connectivity in the motor tracts.
This randomized, single-blind study compares the effectiveness of bilateral training to unilateral training for individuals with moderate hemiparesis. We hypothesize that bilateral training will be superior to unilateral in the proximal extremity but not the distal one.
Aerobic treadmill exercise has been shown to improve walking, cardiovascular fitness and thereby risk factor profiles in chronic stroke patients (Macko et al., Stroke 2005). The proposed project is a randomized controlled trial in geriatric stroke patients with chronic disabilities to investigate potential mechanisms of treadmill therapy. The hypothesis is tested that 3-months of aerobic treadmill exercise induces structural brain plasticity and reorganization. The outcome measures are walking ability, gait pattern, cardiovascular fitness and brain morphology. This study will elucidate fundamental mechanisms of brain adaptations linked to task-repetitive aerobic lower extremity exercise. These mechanisms will not only lead to a better understanding but may also help to identify predictors of treatment response. 40 patients aged over 60 years with lower extremity paresis after a first-ever clinical stroke longer than 6 months prior to study inclusion will be recruited from: 1) The Geriatric Rehabilitation Clinic at the Robert-Bosch Hospital in Stuttgart 2) the Dept of Neurology, University Hospital in Tübingen. Subjects will be randomized to 3 months progressive graded aerobic treadmill exercise training (TAEX; 3 times/week, duration 10-45 min) or an attention control group (CON). Because we expect that localization and size of stroke affect therapy outcomes, stratified randomization will be used to balance entry into groups. We hypothesize that 3 months of treadmill gait training but not conventional care leads to improvements of cardiovascular fitness and gait and to brain reorganization (structural plasticity) in regions in which functional adaptations have been demonstrated using fMRI in previous studies. The specific aims are: - To assess reorganization by comparing cortical thickness, cortical density and fiber tract morphology before (time point 0), and after therapy (3 months) using T1-weighted 3D-MPRAGE images, voxel based morphometry and diffusion tensor imaging. - To correlate brain reorganization with improvements in walking velocity, and analysis of gait patterns (parameters, swing time, stance time, gait symmetry). - To correlate brain reorganization with location and size of the index stroke lesion and of diffuse white matter damage (subcortical vascular encephalopathy). Lesion and white matter damage will be evaluated based on T2-weighted FLAIR sequences.
Impaired hand function is one of the most frequently persisting consequences of stroke. The purpose of this study is to investigate whether two different types of treatment improve recovery of hand function after stroke.
The purpose of this study is to determine if a modified protocol of constraint-induced movement therapy (CIT) is effective in rehabilitation treatment of arm paresis in children with cerebral palsy. In these children one main problem the non-use of the affected arm. Many studies showed that the non-use phenomenon can by reversed by the CIT, a rehabilitation program consisting of 15 days of restraining the unaffected arm plus a daily intensive (6 hours/day) physiotherapy training of the paretic arm. The present study aims at evaluating if a shortened CIT protocol (restraining device plus only 2 weekly hours of physiotherapy) is effective in improving use and function of children paretic arm
The purpose of this study is to assess efficacy, as well as safety, of Ropinirole in improving movement among patients with chronic stroke.
The purpose of this study is to assess the safety and effectiveness of cortical stimulation delivered concurrent with rehabilitation activities to enhance motor recovery in patients suffering from hemiparesis affecting the upper extremity following a stroke.
Stroke is the leading cause of activity limitation among older adults in the United States. NeuroMuscular Electrical Stimulation (NMES) can assist stroke survivors in regaining motor ability and decreasing activity limitation caused by stroke. This study will research the effects of two types of NMES on reducing motor impairment and activity limitation.
The overall goal of this study is to determine whether robotic-assisted gait training is better than standard physical therapy treatments for improving walking ability in hemiparetic stroke patients.
