The effectiveness of walking stick use for neurogenic claudication: results from a randomized trial and the effects on walking tolerance and posture. OBJECTIVES: To determine the immediate effects of using a stick on walking tolerance and on the potential explanatory variable of posture, and to provide a preliminary evaluation of the effects of daily walking stick use on symptoms and function for people with neurogenic claudication. DESIGN: A 2-phase study of neurogenic claudication patients comprising a randomized trial of 2 weeks of home use of a walking stick and a crossover study comparing walking tolerance and posture with and without a walking stick. SETTING: A primary care-based musculoskeletal service. PARTICIPANTS: Patients aged 50 years or older with neurogenic claudication symptoms (N = 46; 24 women, 22 men, mean age 71.26y) were recruited. INTERVENTION: Walking stick. MAIN OUTCOME MEASURES: Phase 1 of the trial used the Zurich Claudication Questionnaire symptom severity and physical function scores to measure outcome. The total walking distance during a shuttle walking test and the mean lumbar spinal posture (measured by using electronic goniometry) were used as the primary outcome measurements in the second phase. RESULTS: Forty of the participants completed phase 1 of the trial, and 40 completed phase 2. No significant differences in symptom severity or physical function were shown in score improvements for walking stick users (stick user scores minus control scores) in the 2-week trial (95% confidence interval (CI) -0.24 to 0.28 and -0.10 to 0.26, respectively). In the second phase of the trial, the ratio of the shuttle walking distance with a stick to without a stick showed no significance (95% CI 0.959 to 1.096) between the groups. Furthermore, the use of a walking stick did not systematically promote spinal flexion; no significant difference was shown for mean lumbar spinal flexion for stick use versus no stick (95% CI 0.351 degrees to 0.836 degrees). CONCLUSIONS: The prescription of a walking stick does not improve walking tolerance or systematically alter the postural mechanisms associated with symptoms in neurogenic claudication.
