Mobility Intensive Training (Mob-IT) Protocol for Children with Cerebral Palsy: Feasibility and Fidelity Results

The Mobility Intensive Training (Mob-IT) protocol is an innovative intervention focused on motor learning to improve the mobility of children with cerebral palsy (CP). The objective was to describe the feasibility and intervention fidelity of Mob-IT. A single-subject experimental study was conducted with four children with CP, a median age of 11 (7–13) years, and a Gross Motor Function Classification System I–III. The Mob-IT included 24 h of practice of mobility goals, delivered three times a week in 2 h sessions over four weeks. Feasibility was assessed using the Qualitative Feedback Questionnaire (QFQ), evaluating adherence, acceptability, adverse effects, the clarity of procedures, and intervention time. The Canadian Occupational Performance Measure (COPM) was used to assess participant and caregiver satisfaction. Fidelity was measured by the type of feedback provided (intrinsic vs. extrinsic), task challenge level, and intervention volume. Participants reported good acceptance, few adverse effects, and satisfaction with the outcomes. The intervention adhered to the proposed principles, with a focus on extrinsic feedback and tasks showing progression over time. Time was well spent, being 78% focused on activities and using mostly extrinsic-focused feedback. The Mob-IT protocol was considered feasible and faithful to its principles. As this is a feasibility study, the results indicate the need to expand the intervention to a larger, randomized study.
