简要总结
Background:
People with cerebral palsy, spina bifida, muscular dystrophy, or spinal cord injury often have muscle weakness and problems controlling how their legs move. This can affect how they walk. The NIH has designed a robotic device (exoskeleton) that can be worn on the legs while walking. The wearable robot offers a new form of gait training.
Objective:
To learn whether a robotic device worn on the legs can improve walking ability in those with a gait disorder.
Eligibility:
People aged 3 to 17 years with a gait disorder involving the knee joint.
Design:
Participants will be screened. They will have a physical exam. Their walking ability will be tested.
Participants will have markers taped on their body; they will walk while cameras record their movements. They will undergo other tests of their motor function and muscle strength.
The study will be split into three 12-week phases. During 1 phase, participants will continue with their standard therapy.
During another phase, participants will work with the exoskeleton in a lab setting. Their legs will be scanned to create an exoskeleton with a customized fit. The exoskeleton operates in different modes: in exercise mode, it applies force that makes it difficult to take steps; in assistance mode, it applies force meant to aid walking; in combination mode, it alternates between these two approaches.
During the third phase, participants may take the exoskeleton home. They will walk in the device at least 1 hour per day, 5 days per week, for 12 weeks.
Participants walking ability will be retested after each phase....
详细描述
Study Description:
This randomized crossover trial will determine whether 12 weeks of overground gait training with a robotic exoskeleton outside of the clinical setting has a beneficial effect on walking ability, muscle activity, and overall gross motor function. Participants will be randomized into two groups, one that receives the exoskeleton therapy first before crossing over to continue standard therapy and one that continues standard therapy before completing the exoskeleton intervention. An in-lab training and accommodation period will be completed prior to the exoskeleton being sent home for use outside the clinical setting. We will monitor exoskeleton use during the intervention period for compliance and safety. Assessments of gait biomechanics, neuromuscular activity and functional mobility will be completed before and after the intervention and at 6 weeks post- intervention. It is hypothesized that the 12-week exoskeleton intervention outside the clinic setting will show greater improvements than the standard therapy.
Objectives:
Primary Objective: To evaluate the effectiveness of a longitudinal robotic exoskeleton gait training paradigm in improving crouch gait from CP or knee extension deficiency from SB, iSCI or MD in children, assessed as improvement in knee angle during walking before and after the intervention period.

结局指标
主要结局
To evaluate the effectiveness of a longitudinal exoskeleton training program in the community, as opposed to a standard regimen of therapy of the same magnitude, at improving knee extension deficiency in children with CP, SB, iSCI or MD.
时间窗: 36 Weeks
The primary endpoint will be knee extension range of motion. This will be assessed using knee angle at two positions in the gait cycle: knee angle at initial contact and peak knee angle during stance
次要结局
- To evaluate improvement in overground walking of children with CP, SB, iSCI or MD as a function of average gait speed while walking with the robotic exoskeleton(15 Weeks)
