Abstract/Notes

OBJECTIVE: The purpose of this study was to assess long-term outcomes of a 6-week multimodal program (manual therapy, exercises, and self-management strategies) in patients with neurogenic claudication due to degenerative lumbar spinal stenosis.

METHODS: This study evaluated 49 patients with neurogenic claudication who completed a 6-week multimodal program between 2010 and 2013. Outcomes included Oswestry Disability Index (ODI), Zurich Claudication Questionnaire (ZCQ), and Numeric Rating Scale. Mean differences, paired t tests, and the Wilcoxon rank-sum test were used to compare outcomes at baseline, 6 weeks, and long-term follow-up.

RESULTS: Twenty-three patients completed the follow-up questionnaire (47% response rate). Median follow-up was 3.6 years (interquartile range: 3.3-4.6). The mean age was 73.5 years (standard deviation: 8.5). Between baseline and long-term follow-up, there were statistically significant and clinically important improvements in disability (ODI: -23.7 [95% confidence interval (CI): -15.7 to -31.6]; ODI walking item: -1.96 [95% CI: -1.34 to -2.57]; ZCQ function scale: -0.42 [95% CI: -0.10 to -0.70]) and pain (leg pain: -3.53 [95% CI: -1.80 to -5.20]; ZCQ symptom scale: -0.71 [95% CI: -0.30 to -1.10]), but not low back pain (Numeric Rating Scale: -1.03 [95% CI: -1.00 to 3.10]). There was no statistically significant change in any outcomes between 6 weeks and long-term follow-up.

CONCLUSION: In a sample of patients with neurogenic claudication participating in a 6-week multimodal program, clinically important improvements in leg pain and disability, but not low back pain while walking, were maintained in the long term (median duration of 3.6 years) when compared to baseline.
