A home exercise programme is no more beneficial than advice and education for people with neurogenic claudication: results from a randomised controlled trial.

OBJECTIVE

To compare the effectiveness of a physiotherapy programme with a control treatment of advice and education in patients with neurogenic claudication symptoms.

DESIGN

Pragmatic randomised controlled clinical trial.

SETTING

Primary care-based musculoskeletal service.

PATIENTS

Adults aged 50 or over with neurogenic claudication symptoms causing limitation of walking.

INTERVENTIONS

Condition-specific home exercises combined with advice and education, or advice and education alone.

MAIN OUTCOME MEASURES

The primary outcome was the difference in improvement of symptom severity scores on the Swiss Spinal Stenosis Scale at eight weeks. Secondary outcomes included measures of physical function, pain and general well-being at eight weeks and 12 months.

RESULTS

There was no significant difference between groups in the Swiss Spinal Stenosis symptom severity scale at eight weeks (t = 0.47, p = 0.643): mean change (SD) control group -0.18 (0.47), treatment group -0.10 (0.66), difference (95% CI) 0.08 (-0.19, 0.35); baseline-adjusted difference 0.06 (-0.19, 0.31)]. An unplanned subgroup analysis suggested that for patients with the top 25% of baseline symptom severity scores, the physiotherapy exercise programme resulted in an improvement in the primary outcome, and modest but consistently better secondary outcomes at both time-points compared to the control group. The effectiveness in different subgroups requires further direct evaluation.

CONCLUSIONS

In the treatment of patients with neurogenic claudication symptoms, a physiotherapist-prescribed home exercise programme is no more effective than advice and education.

ETHICAL APPROVAL

The study was approved by Leeds Central Ethics Committee and informed consent was given by all participating patients.
