AMEsobreRuedas Early Powered Mobility in Children with Spinal Muscular Atrophy Type I: Protocol of a Randomized Controlled Trial.

Background : Young children with spinal muscular atrophy type 1 (SMA1) have limited independent mobility and participation that may lead to cognitive development delays. Implementing early powered mobility in interventions may help them to learn self-initiated movement, play, and having fun to participate in natural settings. The aim of this study is to evaluate the effectiveness of an early power mobility intervention for increasing participation, functional ability, and quality of life in young children with SMA1. Methods : AMEsobreRuedas is a randomized waiting list controlled clinical trial. A sample of 24 children (10 months-5 years old, with SMA1) will be randomly allocated to two groups. The experimental group will perform a family-centered intervention with powered mobility for 16 weeks in their natural environment: a 12-week-structured program three times a week; and a 4-week follow-up with free use of the powered mobility device. The control group (waiting list) will keep their routine and will receive the same intervention after the experimental group. Five assessments will be carried out at baseline and weeks 4, 8, 12, and 16. Primary outcomes are participation (YC-PEM); functional ability (PEDI-CAT); and quality of life (PedsQL-Neuromuscular module). Results : It is expected that this study will provide further knowledge about the positive impact of powered mobility for the analyzed variables. Moreover, family engagement in the intervention and establishment of functional goals may help to add valuable information about real needs in future research. Conclusions : Early powered mobility could increase the opportunities for children with SMA1 to learn to move independently and participate in their natural environment.
