The Baltimore activity scale for intermittent claudication: a validation study.

Neighborhood psychosocial hazards and cardiovascular disease: the Baltimore Memory Study.

OBJECTIVES We examined associations between cardiovascular disease and neighborhood psychosocial hazards, such as violent crime, abandoned buildings, and signs of incivility, to evaluate whether features of place are associated with older adult health. METHODS We analyzed first-visit data from the Baltimore Memory Study of randomly selected residents aged 50 to 70 years (n=1140) of 65 contigu...

Assessment of free-living daily physical activity in older claudicants: validation against the doubly labeled water technique.

BACKGROUND The purpose of this study was to compare physical activity assessed by monitoring devices and questionnaires with the criterion method of physical activity using doubly labeled water (DLW) in free-living peripheral arterial occlusive disease (PAOD) patients. METHODS Twenty-two older nonsmoking PAOD patients with intermittent claudication (age = 68.7 +/- 7.3 years, ankle/brachial in...

Muscle blood flow during exercise in intermittent claudication. Validation of the 133-xenon clearance technique: clinical use by comparison to plethysmography and walking distance.

Increasing walking in patients with intermittent claudication: Protocol for a randomised controlled trial

BACKGROUND People with intermittent claudication are at increased risk of death from heart attack and stroke compared to matched controls. Surgery for intermittent claudication is for symptom management and does not reduce the risk of cardiovascular morbidity and mortality. Increasing physical activity can reduce claudication symptoms and may improve cardiovascular health. This paper presents t...

Patterns of ambulatory activity in subjects with and without intermittent claudication.

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, lightweight step activity monitor attached ...
