Abstract

Objective: The aim of this study was to compare the effectiveness of a combination of aquatic exercise and pain neurophysiology education with aquatic exercise alone in chronic low back pain patients. Design: Single-blind randomized controlled trial. Setting: Outpatient clinic. Subjects: Sixty-two chronic low back pain patients were randomly allocated to receive aquatic exercise and pain neurophysiology education ( n = 30) or aquatic exercise alone ( n = 32). Interventions: Twelve sessions of a 6-week aquatic exercise programme preceded by 2 sessions of pain neurophysiology education. Controls received only 12 sessions of the 6-week aquatic exercise programme. Main measures: The primary outcomes were pain intensity (Visual Analogue Scale) and functional disability (Quebec Back Pain Disability Scale) at the baseline, 6 weeks after the beginning of the aquatic exercise programme and at the 3 months follow-up. Secondary outcome was kinesiophobia (Tampa Scale of Kinesiophobia). Results: Fifty-five participants completed the study. Analysis using mixed-model ANOVA revealed a significant treatment condition interaction on pain intensity at the 3 months follow-up, favoring the education group (mean SD change: −25.4± 26.7 vs −6.6 ± 30.7, P < 0.005). Although participants in the education group were more likely to report perceived functional benefits from treatment at 3 months follow-up (RR=1.63, 95%CI: 1.01–2.63), no significant differences were found in functional disability and kinesiophobia between groups at any time. Conclusions: This study's findings support the provision of pain neurophysiology education as a clinically effective addition to aquatic exercise.
