Biofeedback in pediatric populations: a systematic review and meta-analysis of treatment outcomes

Biofeedback is commonly used for both pediatric and adult patients with a myriad of diagnoses in clinical settings. The majority of previous research has focused on the use of biofeedback in adults, with only a small body of literature examining the usefulness of biofeedback in treating children. The current systematic review and meta-analysis seeks to quantitatively examine the usefulness of biofeedback in addressing pediatric conditions. A systematic review of biofeedback interventions in children was conducted using four databases (Ovid MEDLINE, EMBASE, PsycINFO, and Cochrane CENTRAL). Outcomes included changes in symptoms of associated conditions or changes in physiological functioning. Out of 3,128 identified articles, 23 studies (with 24 effect sizes) were eligible for inclusion in the meta-analysis. Using a random effects model, the overall effect of pediatric biofeedback was statistically significant with a large effect size. Despite the large effect size, general study quality was low, limiting interpretation of findings. Despite widespread clinical use of biofeedback in pediatric populations, research is still limited concerning the efficacy of biofeedback in children. While findings suggest potential positive effects of biofeedback to address pediatric conditions, high-quality studies are necessary to fully support the use of biofeedback in children.
