Purpose:
To examine the prognosis and prognostic factors for patients with chronic low back pain presenting to a private, community-based, group exercise program.
Methods:
A total of 118 consecutive patients with chronic LBP were recruited. Baseline assessments included socio-demographic characteristics, back pain history and clinical examination findings. Primary outcome measures were pain intensity and disability at 3, 6 and 12 months. Potential prognostic factors to predict pain intensity and disability at 12 months were assessed using a multivariate regression model.
Results:
112 (95 %) participants were followed up at 12 months. The majority of participants were female (73 %), had high educational levels (82 %) and resided in suburbs with a high socio-economic status (99 %). Pain intensity improved markedly during the first 6 months (35 %) with further minimal reductions up to 12 months (39 %). Interestingly, disability improved to a greater degree than pain (48 % improvement at 6 months) and continued to improve throughout the 12 months (60 %). Baseline pain intensity accounted for 10 % of the variance in the 1 year pain outcomes. Duration of current episode, baseline disability and educational level accounted for 15 % of the variation in disability at 12 months.
Conclusions:
During a period of 12 months, patients with chronic LBP presenting to a private, community-based, group exercise program improved markedly, with greater improvements in disability than pain. The predictors investigated accounted for only 10 and 15 % of pain and disability outcomes, respectively.
