What this Trial Is About
Researchers are studying how a single session of robot-assisted gait training using the Trexo robotic gait trainer affects rehabilitation in people with physical, cerebral palsy, or developmental disabilities who have trouble walking. The study aims to understand why early benefits of robotic gait trainers occur and to explore different modes of the Trexo device, such as "endurance" mode and "strength" mode, to see their impacts on physical activity, walking, brain function, spasticity, and fatigue. This exploratory trial seeks to improve knowledge on how the Trexo might be modified for better rehabilitation support. Participants will first attend a familiarity and fitting session to get used to the Trexo device and ensure proper fit. Following this, they will complete two testing sessions using different modes of the Trexo: "endurance" mode where the robot moves the participant with a fixed gait pattern, and "strength" mode where the participant assists in the movements. There may be options for additional sessions if participants and their families wish to explore other aspects like brain activity. Each training session lasts up to one hour or until the participant feels they need to stop due to fatigue. During the study, researchers will measure changes in heart rate response to exercise, exercise duration, step counts, perceived exertion, brain and muscle activation, gait characteristics, leg spasticity, and overall physical activity over an average of four weeks. Participants will have three required visits, including the fitting session and two training sessions, with optional additional visits. The study uses randomized assignment to different modes and includes safety monitoring throughout the trial period.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 1 session
Participants complete a single session of robot assisted gait training using the Trexo robotic gait trainer in either "endurance" or "strength" mode. Session length depends on participant fatigue and lasts up to 1 hour.
1 visit (in-person)
Duration - Approximately 4 weeks
Participants are monitored for changes in heart rate response, exercise duration, steps taken, perceived exertion, brain and muscle activation, gait characteristics, spasticity, and physical activity level for approximately 4 weeks after training.
Weekly visits for up to 4 weeks
