Background: This study examined the associations of objectively measured neighborhood built environment characteristics with objectively measured physical activity (PA) in older people with and without lower limb osteoarthritis (LLOA), and assessed whether these relationships differ between both groups.
Methods: Data from the Dutch component of the European Project on OSteoArthritis ...
Objectives: Pain has been known to predict low physical activity (PA) in juvenile idiopathic arthritis (JIA) and high levels of pain are related to maladaptive coping rather than disease severity. Objectively monitored PA in JIA has recently been shown not to be related to pain intensity, emphasizing the need to ...
Background: Sedentary behavior is associated with increased risk of functional decline and disability. Individuals with rheumatoid arthritis (RA) spend more time sedentary than healthy adults. Self-reported assessment of sedentary behavior has not been well-developed in this patient population.
Methods: 172 adults with RA wore an accelerometer for 7 days and completed a ...
Objective: To study the cross-sectional association between physical activity measured with an accelerometer, structural knee abnormalities, and cartilage T2 values assessed with 3T magnetic resonance imaging (MRI).
Methods: We included 274 subjects from the Osteoarthritis Initiative cohort without definite radiographic osteoarthritis (Kellgren/Lawrence grades 0 and 1) and with at most mild pain, ...
Objective: The study objective was to quantify the association between daily physical activity measured by accelerometer and 1-year changes in symptoms among people with knee osteoarthritis.
Methods: Participants from the Osteoarthritis Initiative had knee radiographs and physical activity assessed using GT1M ActiGraph (Pensacola, FL) uniaxial accelerometers at the 48-month ...
Objective: Fatigue is a common symptom in systemic lupus erythematosus (SLE), and engaging in physical activity may reduce fatigue. We aimed to characterize relationships between fatigue, other health status measures assessed with the Patient Reported Outcomes Measurement Information System (PROMIS) instruments, and accelerometer-based physical activity measurements in patients with SLE. ...
Introduction: The aims of the present study were: (a) to examine the agreement between subjective (assessed via the International Physical Activity Questionnaire; IPAQ) and objective (accelerometry; GT3X) physical activity (PA) levels in patients with rheumatoid arthritis (RA), and (b) to evaluate the associations of RA patients’ subjective and objective ...
Background: Physical activity (PA) is beneficial in reducing pain and improving function in lower limb osteoarthritis (OA), and is recommended as a first line treatment. Self-administered questionnaires are used to assess PA, but knowledge about reliability and validity of these PA questionnaires are limited, in particular for patients with OA. ...
Background: More than 650,000 total knee arthroplasties are performed annually to alleviate pain and disability associated with osteoarthritis; a chronic, degenerative condition that compromises the quality of life of 37% of adults over age 60. Despite the decrease in knee pain commonly associated with total knee arthroplasty, little is known about subsequent alterations ...
Objective: To investigate whether objectively measured time spent in light intensity physical activity is related to incident disability and to disability progression.
Design: Prospective multisite cohort study from September 2008 to December 2012.
Setting: Baltimore, Maryland; Columbus, Ohio; Pittsburgh, Pennsylvania; and Pawtucket, Rhode Island, USA.
Participants: Disability onset cohort of 1680 community dwelling ...
