Abstract

Background: The levels of physical activity of patients with intermittent claudication (IC) are usually reduced. The Baltimore Activity Scale for Intermittent Claudication (BASIC) was designed to measure physical activity levels of patients with IC, but its validation was conducted against only two days of monitoring with an accelerometer, and it remains unclear whether BASIC provides information about weekly physical activity levels.

Objective: To analyze the correlation between physical activity levels of patients with IC estimated using BASIC or a pedometer for one week.

Methods: This study included 150 patients with IC aged 30 to 80 years. Sociodemographic data, comorbidities, cardiovascular risk factors and BASIC scores were recorded. Pedometers were used for seven consecutive days, and data were analyzed for three diferent periods (all days, weekdays and weekends).

Results: BASIC scores and mean number of steps were correlated on all days (rho=0.343, p<0.001), weekdays (rho=0.336, p<0.001) and weekends (rho=0.317, p<0.001).

Conclusion: In patients with IC, physical activity levels estimated using BASIC correlate with weekly physical activity levels.
