Background/Objectives: Adolescents with autonomic disorders who attend Intensive Interdisciplinary Pain Treatment (IIPT) programs report improvements in functioning. However, it is unclear whether they experience corresponding improvements in physiological measures. As such, the aim of this pilot study was to examine changes in physiological measures in youth attending an IIPT program who demonstrated excessive postural tachycardia on an active stand test. The secondary goal was to examine associations between physiological measurements and self-reported measures of chronic orthostatic intolerance (cOI) and functioning. Methods: At admission and discharge, eighteen adolescents and young adults (AYAs) attending IIPT (M age = 17.39 years; SD = 2.15 years) completed an active stand test, measures of breathing rate and muscle tension, as well as self-reported measures of cOI symptoms and functioning. Results: AYAs showed significant reduction in active stand test heart rate increase (p < 0.001; d = 1.07) and maximum heart rate (p = 0.002, d = 0.76) from admission to discharge. Improvements were also observed in resting respiration rate (p = 0.001, d = 89) and resting trapezoid tension (p = 0.03, d = 0.49). Although patients showed significant improvements on self-report measures of functioning (p < 0.001, d = 1.78), changes on subjective report of cOI symptoms did not reach significance. Exploratory analyses that only included patients with a POTS diagnosis were consistent with the overall results. Conclusions: Youth who demonstrated excessive postural tachycardia on active stand test at admission to an IIPT showed significant improvements from admission to discharge in their active stand maximum heart rate and heart rate increase, as well as respiration rate, muscle tension, and reports of their functioning. Future research is necessary to examine the mechanisms of change that contribute to symptom improvement.

Objectives: Intensive interdisciplinary treatment is emerging as an effective treatment of chronic pain in youth. These programs often include a parental component with the belief that targeting parental distress and responses to a child’s pain will improve outcomes. However, few studies have evaluated the impact of a parental intervention in the interdisciplinary treatment of pediatric chronic pain. The present study consists of a nonrandomized pre-post design to evaluate change in psychological and behavioral functioning of parents who participated in intensive parent programming that utilized cognitive-behavioral therapy and acceptance and commitment therapy, delivered within the context of an interdisciplinary intensive 3-week pain treatment program for youth with chronic pain. Materials and Methods: Two hundred twelve parents and their children participated in the study, with 116 participants completing 3-month follow-up measures. Parents completed measures of depressive symptoms, pain catastrophizing, protective responses, and psychological flexibility at admission, discharge, and 3 months after the program. Child functional disability was assessed at the same time points. We examined change in parent factors over time, while controlling for change in child distress. Results: Parents reported significant improvements in all areas of functioning from admission to discharge and improvements were maintained at 3-month follow-up. Discussion: This study provides evidence suggesting parent interventions can be effective in reducing parent distress and behaviors known to be associated with child outcomes.
