Physical function and perceived pain following inpatient intensive interdisciplinary pain treatment for children and adolescents.

Abstract

Background: Chronic pain among children and adolescents negatively impacts overall functioning and quality of life. Although Intensive Interdisciplinary Pain Treatment (IIPT) programs aim to reduce functional impairment and perceived pain, overall evidence is limited and restricted by small sample sizes and limited diversity in pain diagnoses.

Objective: To determine whether children and adolescents with chronic pain participating in an inpatient IIPT program experience improvements in their physical function and perceived pain.

Design: Cross-sectional, secondary analysis.

Setting: Inpatient acute rehabilitation.

Participants: Children and adolescents with chronic pain (n = 258; females/males = 204/54; age = 16.5 ± 2.6) admitted to a 4-week inpatient IIPT program from November 2011 to January 2023.

Intervention: Participants attended individual and group sessions involving physical therapy, occupational therapy, aquatic therapy, cognitive behavioral therapy, school-related tasks, and meditation. The sessions focused on improving strength, endurance, and function, while helping participants modify physical sensations, catastrophic thinking, and maladaptive behaviors.

Main outcome measures: Collected at admission and discharge: pain intensity (Numerical Pain Rating Scale; scale: 0-10), lower extremity function (Lower Extremity Functional Scale [LEFS]; scale: 0-80), upper extremity function (Upper Extremity Functional Index [UEFI]; scale: 0-80), motor proficiency (Bruininks-Oseretsky Test of Motor Proficiency, Second Edition short form [BOT-2 SF]; scale: 0-70), and occupational performance and satisfaction (Canadian Occupational Performance Measure [COPM]; scale: 0-10 for both).

Results: Overall, participants reported significant improvements (p < .05) in median LEFS (median change [MC] = +30.5; 25th, 75th percentile range [PR] = 19, 42), UEFI (MC = +21; PR = 12.8, 31), BOT-2 SF (MC = +9; PR = 5, 15), COPM performance (MC = +4; PR = 2.8, 5.4), and COPM satisfaction (MC = +5.6; PR = 3.8, 7.2). Moreover, participants reported significant reduction (p < .05) in median pain intensity (MC = -3; PR = 1, 5). For a majority of participants, MC surpassed previously reported minimally clinical important difference thresholds.

Conclusions: Findings highlight the relevance of inpatient IIPT programs in enhancing physical function and reducing perceived pain in children and adolescents with chronic pain.
