The Effects of a Pedal-Less Bicycle Intervention on Stability Scores Among Children with Autism Spectrum Disorder
The purpose of this preliminary investigation was to determine if a program using pedal-less bicycles could improve stability scores among children with ASD.
A sample of eight children with ASD (average age, 7 ± 1.15) were recruited. The investigators tested each participant on a posturography plate for five consecutive weeks. The group used pedal-less bicycles, three times per week for five consecutive weeks. A MANOVA determined if center of pressure (CoP) or limit of stability (LoS) scores improved within the group.
LoS anterior, LoS posterior, right sagittal, and left sagittal indicated statistically significant improvements over time; the greatest improvement was seen in left sagittal assessments which improved from an average of 1.75 during baseline to an average of 3.03 at week 5.
There was evidence of a significant association between pedal-less bicycles and mean LoS scores among children with ASD. This investigation determined the use of pedal-less bicycles can improve stability scores among children with ASD within a 5-week session, if performed at least three times per week.
