The study by Tefft et al. (2011, in this issue) is one of the few studies that have explored the impact of pediatric powered mobility on families. The parents who participated in their study reported increased satisfaction with their children's social and play skills, ability to move independently, sleeping patterns, and public perception of their children after 4-6 months of powered wheelchair use. In addition, parents rated the wheelchair as having a positive impact on child and family quality of life. Previous research suggests that powered mobility may have positive effects on a variety of child outcomes including perceptual awareness, energy expenditure, functional mobility, participation in age-appropriate activities, and communication and social skills (for a summary of research evaluating effects of pediatric powered mobility see Henderson, Skelton, & Rosenbaum, 2008). It is generally accepted that exploration and interaction with the environment are crucial for child development and powered mobility can provide children with physical disabilities with opportunities to do so.Research conducted with young children with physical disabilities has demonstrated that children as young as 23 months can learn how to use powered mobility devices effectively (Butler, 1986). Despite the potential benefits of early powered mobility use reported in the literature, powered mobility appears to be underutilized (Palisano et al., 2003;Rodby-Bousquet & Hägglund, 2010). Therapists may prefer to pursue more physically active forms of mobility with young children to avoid or defer orthopedic problems and prevent adverse effects on gross motor development. Although the research to date does not provide conclusive answers about the effects of powered mobility use on orthopedic status and motor development, Bottos, Bolcati, Sciuto, Ruggeri, and Feliciangeli (2001) reported that gross motor abilities did not decline after powered wheelchair use. Most importantly, it is essential to consider that powered mobility use does not preclude exploration of other mobility options. A child who uses a powered wheelchair at school to keep up with friends may walk with a walker at home and participate in adapted physical activities within their community. Individuals without disabilities regularly make
