Evaluating a New Knee-Ankle-Foot Brace to Improve Gait in Children With Movement Disorders

Background: - Cerebral palsy (CP) is the most common motor disorder in children. CP often causes crouch gait, an abnormal way of walking. Knee crouch has many causes, so no single device or approach works best for everybody. This study s adjustable brace provides many types of walking assistance. Researchers will evaluate brace options to find the best solution for each participant, and whether one solution works best for the group. Objective: - To evaluate a new brace to improve crouch gait in children with CP. Eligibility: Children 5 17 years old with CP. Healthy volunteers 5 17 years old. Design: All participants will be screened with medical history and physical exam. Healthy volunteers will have 1 visit. They will do motion analysis, EMG, and EEG described below. Participants with CP will have 6 visits. Visit 1: <TAB>1. Motion analysis: Balls will be taped to participants skin. This helps cameras follow their movement. <TAB>2. EMG: Metal discs will be taped to participants skin. They measure electrical muscle activity. <TAB>3. Participants knee movement will be tested. <TAB>4. Participants will walk 50 meters. <TAB>5. Participants legs will be cast to make custom braces. Visit 2: Participants will wear their new braces and have them adjusted. Steps 1 3 will be repeated. EEG: Small metal discs will be placed on the participants scalp. They record brain waves. Participants will have electrical stimulation of their knees and practice extending them. Participants will take several walks with the braces in different settings. Visits 3 5: participants will repeat the walking and some other steps from visit 2. Visit 6 will repeat visit 2.

Cerebral Palsy and the Study of Brain Activity During Motor Tasks

Background: - Two ways to study the brain while people are moving are near-infrared spectroscopy (NIRS) and electroencephalography (EEG). NIRS uses light to look at blood flow in the brain when it is active. EEG records electrical activity in the brain. Both have been used safely for many years, even in very young children. NIRS or EEG can be used while a person is moving to show which parts of the brain are the most active. Researchers want to use NIRS and EEG to study brain activity during movement in people with cerebral palsy and healthy volunteers. Learning more about how people with and without cerebral palsy use their brain to control their muscles may lead to new ways of training people with cerebral palsy to move better. Objectives: - To study how the brain controls body movement in people with and without cerebral palsy. Eligibility: Individuals at least 5 years of age who have cerebral palsy. Healthy volunteers at least 5 years of age. Design: This study has three parts. People with cerebral palsy will be selected for all three. Healthy volunteers will be asked to do only two of them. Everyone who participates will have NIRS and/or EEG exams during movement. People with cerebral palsy may also have biofeedback sessions to train coordination of movement and brain activity. Participants will be screened with a physical exam and medical history. Urine samples may be collected. All participants will have at least one session of NIRS and/or EEG imaging studies. Sessions may also include the following tests: Magnetic resonance imaging to look at the brain Electromyography to measure electrical activity of the muscles Motion analysis of specific body parts Ultrasound to measure activity of the muscles Motorized, robotic, and electrical stimulation of the muscles Other clinical tests of muscle movement as needed. Participants with cerebral palsy will have biofeedback sessions. These sessions will help them learn to coordinate muscle movement and brain activity.

Short-Burst Interval Treadmill Training Cerebral Palsy

Ambulatory children with cerebral palsy (CP) walk predominately in low intensity stride rates with little variability, thus limiting their walking activity and ability to participate in daily life. In contrast, typically developing (TD) children engage in short bursts of intense walking activity interspersed with varying intervals of low intensity walking within daily life. In order to optimize motor learning, active participation, task-specific training and multiple repetitions or massed practice is required to learn new motor skills. Short bursts of vigorous intensity locomotor treadmill training (SBLTT) alternating with low/moderate intensity was specifically designed to mimic activity patterns of TD children in a massed practice format. Pilot data suggests that SBLTT is feasible and enhances walking capacity and performance in daily life for children with CP. This project will examine the effect of SBLTT versus an equivalent dosage of traditional locomotor treadmill training (TLTT) on the primary outcomes of walking capacity and performance in children with CP and whether the effects of SBLTT on walking capacity and performance are mediated by improvements in in muscle power generation. The scientific premise is that SBLTT, that approximates the walking intensity patterns of typically developing (TD) children through a home-based massed practice protocol, will be more effective than TLTT in improving walking capacity and performance. We hypothesize that SBLTT strategies for children with CP modeled on walking patterns of TD children, will be positively mediated by muscle power generation and subsequently improve walking capacity and community walking performance and mobility. Specific aims. Aim #1. Determine the immediate and retention effects of short-burst interval LTT (SBLTT) on walking capacity in ambulatory children with CP. Aim #2. Examine the effects of treatment on community-based walking activity performance and mobility. Aim #3. Explore whether the effects of SBLTT on walking capacity and performance are mediated by muscle power generation. The proposed research will be the first step in a continuum of research that is expected to direct locomotor training protocols and rehab strategies across pediatric disabilities and positively effecting the community walking performance and mobility for children with CP.

Use of Transcranial Magnetic Stimulation and Constraint Induced Movement Therapy in Pediatric Unilateral Cerebral Palsy

Cerebral Palsy (CP) is the most common cause of childhood physical disability. Early CP diagnosis and intervention are crucial to improving outcomes in these patients. Constraint-induced movement therapy (CIMT) has become a standard therapeutic intervention for children with unilateral CP. CIMT utilizes restraining of the unaffected upper limb to stimulate the use of the paretic upper limb enhancing neuroplasticity in the affected cerebral hemisphere. Transcranial magnetic stimulation (TMS) is a safe non-invasive technique that stimulates the brain using repetitive magnetic pulses to enhance neuroplasticity. TMS has been shown to improve symptoms of children with neurodevelopmental disorders such as CP. It is predicted that a combined therapy that uses CIMT and TMS is could improve mobility in children with unilateral CP. To determine if combined therapy is beneficial to children with CP and if use of this therapy is feasible for families, the investigators would like to conducted a feasibility trial. In this trial the investigators will enrol 10 children who have unilateral CP, the participants will either receive: CIMT and TMS or; CIMT and fake TMS, fake TMS consist of a child sitting near the TMS machine but not receiving any TMS. The aim of this project is to determine if it is feasible to conduct a large randomized control trial to compare the effects of combined CIMT and TMS versus CIMT and fake TMS.The investigators also hope that by conducting this trial they can identify any benefits that the addition of TMS may have in children with CP.

Development of a Robotic Ankle Assist Device

The overall objectives of this work is to establish feasibility of a robotic ankle assist device (RAAD) to improve mobility in free-living settings and to establish the RAAD as an effective tool to provide increased dose and precision of targeted ankle therapy. The first specific aim is to complete a personal-use feasibility analysis of ankle mobility assistance. It is hypothesized the children will be able to safely walk faster and travel farther in the community when using the RAAD device vs. without the device. The second specific aim is to gather feedback to design and prototype a minimum viable product for use in clinical and community settings. The third specific aim is to quantify the potential for the RAAD system to increase the effectiveness of clinical gait therapy. Individuals with CP will complete three training sessions: RAAD assistance, RAAD resistance and standard of care. Muscle activity and step activity will be measured during each session. It is hypothesized that the RAAD assistance and resistance therapy will improve ankle plantar-flexor muscle activity and treatment session quality compared to traditional physical therapist-guided gait training. The fourth specific aim is to assess the benefits of repeated gait training with RAAD assistance and resistance. Individuals with CP will participate in a 4-week assistance or resistance intervention and mobility outcomes will be quantified pre and post intervention. It is hypothesized that both assistance and resistance training will improve mobility outcomes.
