Department of Anesthesiology, University Hospital Vrije Universiteit, Amsterdam, The Netherlands Objective: To assess the testretest reliability of two questionnaires for measuring activity limitations in patients with Complex Regional Pain Syndrome type 1 (CRPS I) of the lower extremity. Design: Patients filled out the Walking Stairs Questionnaire and the Questionnaire Rising and Sitting Down twice during a one-week period. Setting: Outpatient pain clinic of a university hospital. Patients: Twenty-one outpatients with CRPS I of the lower extremity. Results: The Walking Stairs Questionnaire and the Questionnaire Rising and Sitting Down were reliable in terms of testretest reliability as expressed by Spearman's r (range 0.790.90 and 0.850.89 respectively) and the ICC (range 0.780.84 and 0.840.87 respectively). Conclusion: Both questionnaires form a reliable tool for measuring activity limitations of patients with CRPS I of a lower extremity.
