Introduction: Promoting physical wellness for preschool-aged children with developmental disorders (DD) is a known challenge. Interventions are more likely to succeed when physical activity opportunities are available to children within the context of their typical environments. We evaluated the feasibility and preliminary effect of 1 potential solution: structured creative dance classes delivered within a preschool environment. Methods: Using a non-randomized feasibility study design, we offered physical activity in the form of creative dance classes for children with and without DD within an inclusive preschool. Classes lasted 30 minutes and were held once a week or 7 weeks. We measured attendance (primary), observed active participation (% of class duration), and balance (Pediatric Balance Scale). Non-parametric descriptive statistics are expressed as median (interquartile range). Balance was evaluated regarding (a) difference between groups at baseline (Mann-Whitney statistic) and (b) intervention effect for children with DD (1-tailed, paired t-test). Results: Twelve preschoolers (age range = 3-5 years) participated: 4 with DD and 8 with neurotypical development. Attendance was 93% (79%-100%) for children with and 100% for children without DD. Per class, rate of active participation in dance activity was 33% (28%-45%) for children with and 80% (71%-82%) for children without DD. Starting balance scores were lower ( P = .014) for children with DD (42 (39-45)) compared to those without (51 (50-52)). Post-intervention, balance scores improved for the children with DD to 50 (50-51) (df = 3, p = .014, t-statistic = 2.35); each child with DD surpassed minimal detectable change for balance. Conclusion: Creative dance classes, delivered within an inclusive preschool environment, are feasible for some preschool-aged children with DD to participate in and efficacious as a physical training challenge at low activity doses. More study is warranted of this potential solution to meet the need for physical wellness promotion among young children with DD.
