Summary
The Baltimore Activity Scale for Intermittent Claudication (BASIC) shows moderate to good reliability for assessing physical activity in patients with intermittent claudication. Reliability is higher in women, younger individuals, and those with lower ankle-brachial index.
Area of Science:
- Vascular Medicine
- Rehabilitation Science
- Clinical Assessment Tools
Background:
- Intermittent claudication, a symptom of peripheral artery disease, significantly impacts patients' quality of life and physical function.
- Accurate assessment of physical activity levels is crucial for managing intermittent claudication and evaluating treatment efficacy.
- The Baltimore Activity Scale for Intermittent Claudication (BASIC) is a questionnaire designed to measure physical activity in this population.
Purpose of the Study:
- To evaluate the test-retest reliability of the Baltimore Activity Scale for Intermittent Claudication (BASIC).
- To identify patient characteristics that may influence the reliability of the BASIC questionnaire.
Main Methods:
- A total of 38 patients with peripheral artery disease and intermittent claudication participated.
- The BASIC questionnaire was administered twice by the same evaluator to each patient, with a 7-day interval between assessments.
- Concordance coefficients were calculated to assess reliability for individual questions and the total score.
Main Results:
- The concordance coefficients for individual BASIC items ranged from 0.43 to 0.85.
- The total BASIC score demonstrated a concordance coefficient of 0.60.
- Higher reliability (concordance coefficients) was observed in women (0.66), younger patients (0.63), and those with a lower ankle-brachial index (0.64).
Conclusions:
- The BASIC questionnaire exhibits moderate to good reliability for assessing physical activity in individuals with intermittent claudication.
- Patient demographics and physiological measures, such as sex, age, and ankle-brachial index, are associated with the reliability of the BASIC scale.
