"Grooving in My Body": A Mixed-Methods Pilot Study of Vibroacoustic Therapy's Effects on Emotion Regulation and Attention in Autistic Children.

: Autistic children often face challenges with attention and emotion regulation, which can impact their socio-communication skills and overall well-being. Vibroacoustic therapy (VAT), a sensory-based intervention using low-frequency sound vibrations, may offer a novel approach to address these challenges. The objective of this pilot study is to explore the feasibility and potential efficacy of VAT in improving attention and emotion regulation in autistic children aged 9-12 years. : Eighteen children were recruited with assistance from the school psychologist, using purposive sampling to identify participants with autism spectrum disorder and attentional challenges. The study was conducted at a primary school in Pretoria, South Africa, in March 2023. Participants were divided into treatment (n = 9) and control (n = 9) groups. The treatment group underwent 10 VAT sessions over six weeks. Attention was assessed using the NEPSY-II and Joint-Attention Test (JTAT), focusing on sustained, selective, alternating, and joint attention. Qualitative data were collected through observations and creative semi-structured interviews to understand the children's experiences of VAT. Tests were conducted at baseline, midway, post-intervention, and one week post-intervention. Statistical analysis was conducted using a Generalised Linear Mixed Model (GLMM) in R version 4.3.1, with significance assessed using a Likelihood Ratio Test ( < 0.05) to assess attention improvements. : Quantitative analysis revealed significant improvements in joint attention in the treatment group (X = 11.64, df = 3, = 0.008). Qualitative findings highlighted positive experiences related to emotion regulation, with children reporting a sense of calm and enjoyment during VAT sessions. Teachers also noted improvements in attention and engagement. : VAT appears to be a feasible and acceptable intervention for autistic children, with potential benefits for attention and emotion regulation. These findings support further research to validate its efficacy and explore its adaptability for diverse sensory profiles. VAT may hold promise as a holistic therapeutic tool in autism intervention programmes.
