Investigating the Feasibility of Locomotor Training for Children Under 5 Years With Complex Neurodisabilties

Purpose: Children with neurodisabilities, including cerebral palsy and rare diseases, often experience significant mobility limitations. Locomotor training, including a combination of partial body weight–supported treadmill training and overground walking in a supported stepping device, may support functional development. This study evaluated the feasibility of a 6-week locomotor training program for young children with neurodisabilities and significant motor impairments. Methods: A single-group pre–post study included 71 children (mean age = 2.8 years). Feasibility was assessed using Bowen’s framework across 4 domains: limited efficacy testing, practicality, acceptability, and adaptability. Outcome measures included Goal Attainment Scaling, Canadian Occupational Performance Measure, 10-m walk test, and 6-minute walk test. Results: All outcome measures improved. Goal Attainment Scaling scores increased from 12.8 to 56.2, with 85% achieving goals. Canadian Occupational Performance Measure and mobility outcome measures exceeded clinically meaningful thresholds. The program was well-tolerated (mean therapy hours = 14.1), was adaptable across a heterogeneous cohort, and there were no major adverse events. Conclusions: Locomotor training involving partial body weight–supported treadmill training and overground walking in supported stepping devices is feasible and beneficial for young children with neurodisabilities and significant motor impairments. Further studies are warranted to explore long-term efficacy and generalizability.
