18 Clinical Trials for Various Conditions
The objective of this study is to investigate the effects of personalized, adaptive, current-steering functional electrical stimulation (FES) of the lower leg to improve gait in people with foot drop.
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.
The purpose of this research study is to test the utility of an ankle robot in people with ankle weakness and foot drop from a peripheral nervous system injury due to neuromuscular or orthopedic injury.
Deficits in ankle control after stroke can lead to foot drop, resulting in inefficient, aberrant gait and an elevated falls risk. Using a novel ankle robot and newly invented adaptive control system, this study tests whether robotic-assisted treadmill training will improve gait and balance functions in chronic stroke survivors with foot drop impairment. It is hypothesized that, compared to treadmill training alone, integrating adaptive ankle robotics with treadmill training will reduce drop foot during independent overground walking, resulting in greater mobility, improved postural control, and reduced fall risk.
The objective of this study is to determine the effectiveness of the NESS L300 (L300) in improving gait parameters, function, and quality of life among stroke subjects (greater than or equal to 3 months post stroke)with drop foot.
This study is designed to see if children with acute lymphoblastic leukemia who have developed foot drop during treatment for their leukemia consume less oxygen when walking with or without an ankle brace designed to support their foot during walking. In this study children with foot drop are asked to walk for six minutes with and without brace on their ankle. During each walk, the amount of oxygen used is measured. The child wears a face mask which is attached to a device that records how much oxygen they use. The amount of oxygen used during the walk with the brace on will be compared to the amount of oxygen used with the brace off.
The primary aim of this study is to: 1. Collect pilot data on the effect of task-specific lower extremity training using the Anklebot on subjects with Multiple Sclerosis (MS) and who have foot drop; 2. Collect pilot data on the use of combination therapy on improving gait in subjects with MS. This therapy will use both Anklebot training and robot-assisted gait training. Hypothesis: Both trainings will result in improved walking performance, but the combination therapy will result in greater gains than ankle training alone.
The objective of this research is to determine if electrical stimulation can improve the strength and coordination of the lower limb muscles, and the walking ability of stroke survivors. The knowledge gained from this study may lead to enhancements in the quality of life of stroke survivors by improving their neurological recovery and mobility. The results may lead to substantial changes in the standard of care for the treatment of lower limb hemiparesis after stroke.
The randomized study (in Phase II of the U44) compares the efficacy and durability of 9 weeks (18 sessions) of robot-assisted physical therapy (PTR) versus physical therapy (PT) alone on foot drop as assessed by gait biomechanics (ankle angle at initial contact, peak swing ankle angle, number of heel-first strikes - % total steps, gait velocity) and blinded clinician assessment (dorsiflexion active range of motion, ankle muscle strength, assistive device needs).
The purpose of this study is to compare acute nerve decompression versus nonoperative treatment in the management of peroneal nerve palsy after total knee arthroplasty (TKA). We hypothesize that acute nerve decompression patients will have better long-term outcomes to patients treated non-operatively for peroneal nerve palsies after TKA.
This is a small pilot randomized controlled trial which will enroll both subacute (\<6 mos) and chronic (\>6 mos) stroke survivors with ankle dorsiflexion weakness. The subjects will be randomized to Contralaterally Controlled Neuromuscular Electrical Stimulation (CCNMES) versus control. The primary objective of this study is to compare the effect of 6-weeks of lower extremity CCNMES, applied in an anti-phase application, on motor impairment and functional mobility to a control group.
The purpose of this study is to examine the changes in reflex pathways in the paretic ankle plantarflexors in individuals with post-stroke hemiparesis using operant conditioning. We are recruiting 5 individuals with chronic post-stroke hemiparesis with foot drop in the affected leg to participate in the reflex training procedure. The study involves 40 visits with a total study duration of about 4 months.
The ability to voluntarily move the ankles is important for walking. After spinal cord injury (SCI), this ability is impaired because of changes in the communication between the brain, spinal cord, and body. Whole body vibration (WBV) is a treatment that increases voluntary muscle control and decreases uncontrollable muscle movement in people with SCI. The purpose of this study is to understand how WBV can impact ankle control and uncontrollable muscle movement.
PURPOSE: The purpose of this study will be to identify whether patients in the subacute stage of stroke, who demonstrate foot drop, will have better gait outcomes when using a Double Adjustable AFO, or a Posterior Leaf Spring AFO. A secondary purpose will be to determine whether one week of practice significantly changes gait outcomes with either of the AFO conditions. INCLUSION CRITERIA: Twenty participants over the age of 18, of any gender and ethnicity, diagnosed with first time unilateral stroke, 4 - 20 weeks post-stroke onset, resulting in hemiparesis with foot drop will be recruited for this study. EXCLUSION CRITERIA: 1. Not able to receive a double adjustable AFO through their insurance 2. Unable to follow two steps commands 3. Unable to ambulate 20 feet with or without assistive device with a minimum level of assistance of contact guard assistance. 4. Cerebellar Stroke 5. Inability to ambulate prior to stroke 6. receiving chemotherapy at the time of study OUTCOME MEASURES: 1. Six Minute walk test 2. Gait Symmetry and Gait velocity measured with GAITRite for self paced velocity walk and fast paced velocity walk. DATA COLLECTION: Data will be collected three times over two weeks period. First Visit: Demographics, Fugl-Meyer Lower Extremity Assessment of sensorimotor function, Mini Mental State Examination 6MWT and GAITRite measurements using Both types of AFO in a random order. Afterwards participant will be given one type of AFO (randomly selected) to practice walking for a week. Second Visit: 6MWT and GAITRite measurements using the type of AFO they were practicing with. Then the other type of AFO will be given to practice walking for a week. Third Visit: 6MWT and GAITRite measurements using the second type of AFO that they were practicing with the week prior. Patient will be asked which type of AFO they prefer to use.
Our proposal quantitatively analyzes gait dynamics of hemiplegic individuals in response to the Function Electrical Stimulation (FES) intervention and identifies the responders to the intervention. This study will improve our knowledge of FES intervention and help clinicians strategize the FES interventions more effectively based on the responders' gait characteristics, thus supporting the NINDS' fundamental goal of translating basic and clinical discoveries into better ways to prevent and treat neurological disorders.
Ankle dorsiflexor weakness (paresis) is one of the most frequently persisting consequences of stroke. The purpose of this exploratory study is to compare two different treatments -- Contralaterally Controlled Neuromuscular Electrical Stimulation (CCNMES) and Cyclic Neuromuscular Electrical Stimulation (cNMES) -- for improved recovery of ankle movement and better walking after stroke.
This study is being done to test the possible benefits of task-specific focused ankle training using the Ankle-Bot on subjects with Multiple Sclerosis who have "foot-drop." The study also compares the effectiveness of task-specific focused ankle training using the Ankle-Bot with conventional focused ankle therapy in improving the gait of subjects with MS.
The presence of foot drop limits normal gait. Our prior data has suggested that approximately 30% of MS patients have foot drop. Although we have observed that "task-specific" rehabilitation using the Lokomat can improve ambulation in chronic MS patients, subjects with "foot drop" have difficulty translating task-specific training to normative gait patterns over ground, despite improving speed and endurance. One of the key limitations of the Lokomat is a lack of robot-assisted training for the ankle joint. The Anklebot, an MIT-developed rehabilitation robot for the ankle, has the potential to address this. The device can move throughout three planes and train ankle flexion, extension, inversion and eversion; however, therapy with the Anklebot alone does not train the knee or hip. We plan to test whether subject foot drop and overall gait benefit more from Anklebot therapy alone or a combination of Anklebot and Lokomat.
