The Portable Children’s Biofeedback Therapy Device market comprises compact, wearable systems that capture physiological signals—such as EEG, heart‑rate variability, and skin conductance—to deliver real‑time feedback for managing anxiety, ADHD, autism spectrum disorders, and other neurodevelopmental conditions in children. Growing clinical validation and parental preference for non‑pharmacologic interventions have heightened its relevance in pediatric care. According to recent industry analyses, the Portable Children’s Biofeedback Therapy Device market size reached approximately USD 210 million in 2025, and the market forecast projects a CAGR of 8.5% through 2033, underscoring a robust growth outlook and accelerating industry expansion. Key macro drivers include rising prevalence of childhood neurodevelopmental disorders, increased reimbursement for digital therapeutics, and rapid advances in miniaturized sensor technology. The sector is further shaped by three dominant forces: (1) technological convergence of AI‑enabled analytics with wearable hardware, (2) evolving regulatory frameworks that streamline device approvals for pediatric use, and (3) shifting consumer behavior toward at‑home therapeutic solutions.
