“…In summary, this investigation found that: (I) ABI, BMI, gender, and current smoking status were independent predictors of the distance to onset of claudication pain and the distance to maximal pain, (2) the regression equations for predicting the distances to onset and to maximal claudication pain were successfully cross-validated on an independent group of similar PAOD patients, and (3) use of the regression equations to predict the measured claudication pain distances were more accurate than compared to the self-report method.…”

Practical Equations to Predict Claudication Pain Distances from a Graded Treadmill Test

et al. 1996

Treadmill testing is used to estimate the severity of claudication, but routine use is not practical or cost-effective in all settings. Thus, the purposes of this study were: (1) to develop and cross-validate prediction equations for treadmill claudication pain distances in a heterogeneous cohort of peripheral arterial occlusive disease patients, and (2) to determine if the regression equations were more accurate in assessing claudication distances than self-reported distances of patients. Medical history, vital signs, resting ankle/brachial systolic pressure index (ABI), and claudication distances during a graded treadmill test were obtained on a validation group of 178 claudicants and on a cross-validation group of 94 c1audicants. The independent predictors of claudication pain distances of the validation group were ABI, body mass index, gender, and current smoking status, with multiple correlation coefficients of R=0.73 and R=0.82 for the distances to onset and to maximal pain, respectively. These equations were successfully cross-validated on an independent group of claudicants, as the predicted distances to onset of claudication pain (167.2±102.6 m) and to maximal pain (354.6±154.3 m) were similar (p=0.99) to measured distances (169.1±127.8 m and 356.6±181.0 m, respectively). However, the selfreported distances to onset (89.5±126.3) and to maximal claudication pain (189.2±284.3) were 1-2 blocks less than either the measured or predicted distances (p

“…To evaluate walking capacity, the patients underwent a treadmill (WTL model, Imbrasport, Brazil) test using a specific progressive protocol for individuals with IC, in which speed is constant at 3.2 km/h and grade is increased 2% at each two minutes until maximal pain 16 . All individuals were already familiar with this protocol before the study.…”

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 different 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.
