Manual Physical Therapy in the Treatment of Functional Constipation in Children: A Pilot Randomized Controlled Trial

Abstract

Objectives: Make a preliminary assessment of the efficacy of manual physical therapy (MPT) compared to conventional pharmacologic treatment (CPT) in chronic pediatric functional constipation (CPC). Design: A pilot randomized and controlled trial was conducted. Settings/Location: Subjects were recruited in a tertiary university hospital in the north of Spain. Subjects: Forty-seven children (2-14 years) were included. Participants were assessed by Pediatric Gastroenterologist. They were recruited in a tertiary university hospital. Subjects were randomly allocated. MPT was performed in a private clinic. Interventions: Control group (CG) received CPT and intervention group (IG) received MPT, consisting in nine sessions of MPT with a 45-min initial session and 30 min for the rest of sessions distributed weekly during the first and second months and biweekly in the third month. Outcome Measures: At times 0-1-3 months and 5 years, results obtained were checked and compared, according to the defecatory pattern ("Symptom Severity Score" SSS), quality of life (Pediatric Quality of Life Inventory Scale), Bristol Stool Form Scale (BSFS), and the defecation frequency (DF). Results: Results from SSS, BSFS, and DF revealed no statistically significant differences between groups in median values at any follow-up. However, there were significant changes over time. The full sample median for SSS was reduced from baseline 24 (interquartile range 20-27) to 11 (6-13) at month 1, 7 (3-13) at month 3, (8 CG; 5 IG), and 5 (1-12) at year 5. The BSFS scale increased from 2 (1-3) at baseline to 4 (3-4) at month 1 and year 5. DF increases progressively from 1 per week to 5 in the fifth year. Higher rates of quality of life were observed at month 3 in IG for the total, physical, and emotional functioning scores and at fifth year for total, emotional, social, and school functioning scores. Conclusions: This study gives preliminary evidence of no difference between MPT and CPT for improvement in measures of CPC, although there was some advantage for MPT in quality of life. Study results justify the conduct of a full-scale efficacy trial of MPT, as well as a noninferiority trial comparing MPT and CPT.
