Written by AI, not yet AICS's view · claude-haiku-4-5-20251001
This review examines how powered mobility devices should be understood for children with spinal muscular atrophy type I (SMA), especially now that new disease-modifying treatments have changed survival outcomes. The authors argue that powered mobility is not just transportation but a developmental intervention that enables children to explore, play, interact socially, and participate in daily life. The review proposes shifting rehabilitation from focusing only on motor function toward enabling children's participation, autonomy, and quality of life within their families and communities.
Key points
Disease-modifying therapies have changed SMA type I from a survival-focused condition to one where participation and quality of life are now priorities
Early powered mobility facilitates exploration, play, social interaction, autonomy, and participation in children with severe motor disabilities
Benefits of powered mobility extend beyond driving skills to supporting quality of life and family well-being when used in meaningful daily contexts
Independent mobility acts as a facilitator of developmental opportunities through interaction between the child, family, and environment
Rehabilitation models for SMA should shift from motor-centered approaches toward participation-oriented models
Limitations
This is a narrative review that synthesizes existing evidence rather than presenting original research data. The document does not provide specific quantitative outcomes or detailed information about the characteristics of children studied in the referenced research programs.
Abstract
Background: Disease-modifying therapies have profoundly changed the natural history of spinal muscular atrophy (SMA) type I, shifting rehabilitation priorities beyond survival and motor function toward participation, autonomy, and quality of life. However, rehabilitation models have not evolved at the same pace, and the role of early powered mobility in this new clinical scenario remains insufficiently conceptualized. Methods: This narrative review integrates current evidence on early powered mobility in children with severe motor disabilities with contemporary rehabilitation frameworks, including the International Classification of Functioning, Disability and Health (ICF), participation-based therapy, family-centered care, and the concept of on-time mobility. Evidence from the AMEsobreRuedas research program is incorporated to develop a conceptual framework for early powered mobility in children with SMA type I receiving disease-modifying therapies. Results: Current evidence suggests that early powered mobility should be understood as a developmental rehabilitation intervention rather than solely as an assistive technology for transportation. Independent mobility facilitates exploration, play, social interaction, autonomy, and participation, while positively influencing family experiences and expectations. Findings from the AMEsobreRuedas program further indicate that the benefits of powered mobility extend beyond driving skill acquisition, supporting participation, quality of life, and family well-being when implemented within meaningful daily contexts. Based on this evidence, a conceptual framework is proposed in which independent mobility acts as an early facilitator of developmental opportunities, with participation emerging through the interaction between the child, family, and environment. Conclusions: In the era of disease-modifying therapies, rehabilitation in SMA should move from a motor-centered approach toward a participation-oriented model. Early powered mobility represents a key intervention for promoting developmental opportunities and meaningful participation rather than simply compensating for motor impairment. The proposed conceptual framework may support clinical decision making and provide a foundation for future rehabilitation research in pediatric neuromuscular disorders.
