To compare biofeedback assisted relaxation training (BART) with distraction therapy for pain during botulinum neurotoxin A (BoNT-A) treatment. This was a crossover randomized controlled trial. Eligible participants were 7 years and older with neurological conditions. Participants were randomized to receive BART or distraction during their first BoNT-A treatment, followed by the alternative intervention in their subsequent BoNT-A treatment. BART was delivered via BrightHearts, an interactive heart-rate-responsive application. Outcomes were pain (Faces Pain Scale - Revised), fear (Children's Fear Scale), and anxiety (numerical rating scale, State-Trait Anxiety Inventory). Demographics, paired t-tests, and linear mixed models were used to compare outcomes. Thirty-eight participants (mean [SD] age 13 years 5 months [3 years 4 months], 20 males, 34 with cerebral palsy) completed both interventions. There were non-significant differences in overall pain (mean difference - 0.05, 95% confidence interval [CI] -0.91 to 0.80, p = 0.902) and worst pain (mean difference 0.37, 95% CI -0.39 to 1.13, p = 0.334) when using BART and distraction therapy. There were non-significant differences in fear and anxiety between interventions. Younger age, heightened pre-procedural state anxiety, and Gross Motor Function Classification System levels III and IV were associated with poorer outcomes (p < 0.05). Participants who received BART before distraction therapy reported lower pain and anxiety scores during both BoNT-A treatments (p < 0.05). Children reported similar pain when using BART and distraction therapy. Those who used BART before distraction therapy reported lower pain and anxiety during both treatments. Children reported similar pain (overall; worst) when using biofeedback assisted relaxation training (BART) and distraction therapy. Children who used BART before distraction therapy reported lower pain and anxiety over both botulinum neurotoxin A treatments. Younger age, pre-procedural state anxiety, and Gross Motor Function Classification System levels III and IV predicted a worse pain experience. Distraction therapy and BART were acceptable non-pharmacological interventions for procedural pain management. © 2022 Mac Keith Press.
