OBJECTIVES To determine the test-retest reliability of the distance covered and the steps taken to complete a 6-minute walk test by peripheral arterial occlusive disease (PAOD) patients with intermittent claudication. To determine the relationship between the total distance and steps covered during the 6-minute walk test and clinical measures of PAOD(More)
OBJECTIVES The Health ABC Long Distance Corridor Walk (LDCW) was designed to extend the testing range of self-paced walking tests of fitness for older adults by including a warm-up and timing performance over 400 meters. This study compares performance on the LDCW and 6-minute walk to determine whether the LDCW encourages greater participant effort. (More)
PURPOSE This study compared the patterns of ambulatory activity in subjects with and without intermittent claudication. METHODS The study participants were 98 subjects limited by intermittent claudication and 129 controls who were matched for age, gender, and race. Subjects were assessed on their ambulatory activity patterns for 1 week with a small,(More)
BACKGROUND Physical activity is associated with health-related quality of life (HRQL) in clinical populations, but less is known whether this relationship exists in older men and women who are healthy. Thus, this study determined if physical activity was related to HRQL in apparently healthy, older subjects. METHODS Measures were obtained from 112 male(More)
BACKGROUND This prospective, randomized, controlled clinical trial compared changes in primary outcome measures of claudication onset time (COT) and peak walking time (PWT), and secondary outcomes of submaximal exercise performance, daily ambulatory activity, vascular function, inflammation, and calf muscle hemoglobin oxygen saturation (StO2) in patients(More)
PURPOSE To determine the walking economy before and after the onset of claudication pain in patients with peripheral arterial disease (PAD), and to identify predictors of the change in walking economy following the onset of claudication pain. METHODS A total of 39 patients with PAD were studied, in which 29 experienced claudication (Pain group) during a(More)
PURPOSE This study was conducted to determine the association between the characteristics of calf muscle hemoglobin oxygen saturation (StO(2)) and exercise performance in patients with intermittent claudication. METHODS The study comprised 39 patients with peripheral arterial disease limited by intermittent claudication. Patients were characterized on(More)
PURPOSE This study was undertaken to determine the natural history of physical function in older men limited by intermittent claudication. METHODS Forty-three men limited by intermittent claudication (mean age, 69 +/- 7 years) were recruited and followed up for 18 months. At baseline the patients reported a history of intermittent claudication for 6.1 +/-(More)
The purpose of this study was to determine whether physical activity level was directly and independently related to the ankle/brachial systolic blood pressure index (ABI) in subjects without peripheral arterial occlusive disease (PAOD). A total of 353 subjects between the age of 38 and 88 years (63.7 +/- 9.1 years; mean +/- standard deviation) who had ABI(More)
OBJECTIVE This study compared the exercise performance of patients with peripheral arterial disease (PAD) who have different types of exertional leg pain. METHODS Patients with PAD were classified into one of four groups according to the San Diego Claudication Questionnaire: intermittent claudication (n = 406), atypical exertional leg pain causing(More)
