Summary
# Editorial Summary Therapeutic horseback riding (THR) has shown promise as an intervention for children with autism spectrum disorder, yet replication of efficacy across different settings and deeper understanding of its mechanisms remain important. This randomised controlled pilot trial assigned 16 children aged 6–16 years (eight per group) to either 10 weeks of THR or barn-based activity without horse interaction, collecting weekly saliva samples before and 20 minutes after sessions to measure cortisol response alongside behavioural assessments. Compared to controls, THR participants demonstrated significant improvements in hyperactivity and social awareness, with marginal gains in irritability and social communication, though no measurable changes in speech production. Notably, the analysis revealed a biobehavioural relationship specific to the riding group: children who presented with higher pre-lesson irritability or hyperactivity showed proportionally smaller cortisol reductions following their lesson—suggesting that while THR produces behaviour benefits, the neuroendocrine (HPA axis) response varies according to baseline behavioural state. These findings partially replicate earlier trial results and point toward cortisol regulation as a potential biological mechanism underlying THR's effects on hyperactivity and irritability, which has implications for practitioners seeking to understand which children may benefit most and how to tailor frequency or intensity of intervention based on presenting behaviours and stress physiology.

Practical Takeaways
- •Therapeutic horseback riding appears effective for reducing hyperactivity and improving social awareness in children with autism; effects may be mediated through HPA axis regulation
- •Children with higher baseline irritability or hyperactivity may show different physiological responses to riding; individual assessment may help identify responders
- •THR benefits appear behavioral and physiological rather than linguistic, so should be combined with other speech-language interventions rather than used as a replacement
Key Findings
- •THR participants showed significant improvements in hyperactivity and social awareness compared to barn activity controls over 10 weeks
- •Greater pre-lesson irritability and hyperactivity were associated with smaller post-lesson cortisol reduction in the THR group but not controls
- •Cortisol response patterns suggest HPA axis dysregulation may be a target mechanism for THR effects on behavior in children with ASD
- •Language production outcomes (word count) showed no significant differences between THR and control groups
