Abstract
Background: The authors previously reported the early results of a trial of a brief psychological intervention to increase physical activity in patients with intermittent claudication. After 4 months, participants in the intervention group walked a mean of 1576 more steps per day than control group participants. The present study followed the original participants to determine whether this behaviour change was maintained over 2 years. Methods: This was a randomized single-centre parallel-group trial. Fifty-eight patients newly diagnosed with intermittent claudication were assigned randomly to one of two groups. The control group (30 patients) received usual care: lifestyle advice and consultation with a vascular surgeon to agree a treatment plan. The treatment group (28) received usual care plus a brief psychological intervention designed to modify illness and walking beliefs, and develop a personalized walking action plan. The primary outcome was daily steps measured by pedometer. Secondary outcomes included revascularization rate, quality of life and perceived pain-free walking distance. Follow-up was conducted at 1 and 2 years. Between-group differences were analysed by analysis of co-variance. Results: Participants in the brief psychological intervention group walked significantly more than those in the control group. The mean difference at 1 year was 1374 (95 per cent confidence interval 528 to 2220) steps per day and the difference at 2 years was 1630 (495 to 2765) steps per day. Conclusion: Modifying illness and walking beliefs, and assisting patients to develop a personalized walking action plan led to increases in walking behaviour in patients with claudication that were maintained for 2 years.
