A common problem among children with nervous system disorders is difficulty walking on their own. This has impacts beyond mobility including short and long-term health conditions associated with physical inactivity and different developmental experiences as a result of the mobility impairments. A robotic trainer can both provide rehabilitation and be an assistive device to help compensate for difficulties. Figuring out how to prescribe it is critical to improve daily life for children with significant disabilities. Preliminary use of robotic trainers have shown many benefits, such as better head control and improved independence in transfers, which greatly increases ability to live independently. Additionally, vital functions that are frequently impaired in those with less physical activity, such as sleep and bowel habits, seem to improve. Finally, these children enjoy using them. This project aims to determine who is most likely to benefit from training with a robotic trainer and investigate key details about the dose of training that is needed. Families that are already using or hope to use robotic training need this data to help improve their access to the intervention. Clinicians need this systematic approach to building evidence to ensure a future multi-centre randomized control trial is well designed. This study is needed to help improve the lives of those who live with significant disabilities. The objective is to evaluate the feasibility and impacts of delivering robotic gait training at home. Integral in this study is capturing the user perspectives. This will both provide preliminary evidence-based advice to potential users, their families, and clinicians as well as provide key metrics to design a definitive multi-centre randomized control trial. The investigators will provide robotic gait trainers, specifically Trexo robotic gait trainers, to participants and their families to use in their home communities for 12 weeks to evaluate the feasibility and impacts of intensive robotic gait training in people who cannot walk independently. Assessments will be completed throughout the duration of study, including before, during, and after the training intervention, with the goal of evaluating a wide range of feasibility considerations and impacts from robotic training.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Training Time | Time spent in the trainer each session, total time spent in the trainer (weekly, monthly). | Assessed throughout the 12 weeks (Week 5 through Week 16) robotic training period. | |
Primary | Training Frequency | Frequency of training sessions (days/week). | Assessed throughout the 12 week (Week 5 through Week 16) robotic training period. | |
Primary | Canadian Occupational Performance Measures (COPM) | Structured questions and rating scales to determine problem areas and goals for training. Identified problems are scored on a 10 point scale, 1 being not able to complete the task at all. | Assessed at enrollment (Week 0), before Robotic Gait Training period (~Week 4), following Robotic Gait Training period (~Week 16), and at 3-months post-training (~Week 28). | |
Primary | Goal Attainment Scaling | Rating of success in achieving an outcome or desired goal (identified using the COPM), where 0 = the expected level of achievement, -2 = much less achieved than expected, and +2 = much more achieved than expected. | Assessed at enrollment (Week 0), before Robotic Gait Training period (~Week 4), following Robotic Gait Training period (~Week 16), and at 3-months post-training (~Week 28). | |
Primary | Early Clinical Assessment of Balance (ECAB) | Clinical balance assessment to determine participant's balance capabilities. | Assessed monthly from time of enrollment through 3-months post-training. | |
Secondary | Number of Participants Enrolled and Completed | Assessment of number of participants that start the study and how many are able to complete the study. | Assessed throughout the study duration, an average of 7-9 months depending on time of enrollment.. | |
Secondary | Caregiver Priorities & Child Health Index of Life with Disabilities (CP-CHILD) | Qualitative assessment of impacts of robotic gait training on participants and families. | Assessed before (~Week 4) and after (~Week 16) robotic gait training. | |
