ObjectiveTo examine the effect of adding aerobic exercise to conventional physiotherapy treatment for patients with chronic low back pain (LBP) in reducing pain and disability.DesignRandomized controlled trial.SettingA physiotherapy outpatient setting in Hong Kong.ParticipantsPatients with chronic LBP (N=46) were recruited and randomly assigned to either a control (n=22) or an intervention (n=24) group.InterventionsAn 8-week intervention; both groups received conventional physiotherapy with additional individually tailored aerobic exercise prescribed only to the intervention group.Main Outcome MeasuresVisual analog pain scale, Aberdeen Low Back Pain Disability Scale, and physical fitness measurements were taken at baseline, 8 weeks, and 12 months from the commencement of the intervention. Multivariate analysis of variance was performed to examine between-group differences.ResultsBoth groups demonstrated a significant reduction in pain (P<.001) and an improvement in disability (P<.001) at 8 weeks and 12 months; however, no differences were observed between groups. There was no significant difference in LBP relapse at 12 months between the 2 groups (χ(2)=2.30, P=.13).ConclusionsThe addition of aerobic training to conventional physiotherapy treatment did not enhance either short- or long-term improvement of pain and disability in patients with chronic LBP.Copyright © 2011 American Congress of Rehabilitation Medicine.
