Accelerometer-assessed daily physical activity in relation to pain cognition in juvenile idiopathic arthritis

  • Published on Jun 2016

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 ...


Comparison of Subjective and Objective Measures of Sedentary Behavior Using the Yale Physical Activity Survey and Accelerometry in Patients with Rheumatoid Arthritis

  • Published on Apr 2016

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 ...


Association of Physical Activity Measured by Accelerometer, Knee Joint Abnormalities, and Cartilage T2 Measurements Obtained From 3T Magnetic Resonance Imaging: Data From the Osteoarthritis Initiative

  • Published on Sep 2015

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, ...


Objectively Measured Physical Activity and Symptoms Change in Knee Osteoarthritis

  • Published on Feb. 2, 2016

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 ...


Fatigue, patient reported outcomes, and objective measurement of physical activity in systemic lupus erythematosus

  • Published on Feb. 10, 2016

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. ...


Subjective and objective levels of physical activity and their association with cardiorespiratory fitness in rheumatoid arthritis patients

  • Published on March 13, 2015

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 ...


Reliability and validity of the Physical Activity Scale for the Elderly (PASE) in patients with hip osteoarthritis.

  • Published on Feb, 21, 2012

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. ...


Lack of Physical Activity Level Alteration Post-Total Knee Arthroplasty

  • Presented on May 29, 2014

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 ...


Relation of physical activity time to incident disability in community dwelling adults with or at risk of knee arthritis: prospective cohort study

  • Published on April 29, 2014

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 ...


Safety and feasibility of a home-based six week resistance training program in juvenile idiopathic arthritis

  • Published on Dec. 20, 2013

Background: Juvenile idiopathic arthritis (JIA), among the most common chronic diseases of childhood, can be associated with attenuated physical activity levels, reduced fitness, decreased functionality and pain. This pilot study aimed to determine the safety, feasibility and effect of a six week resistance training program in children with JIA. Methods: ...
