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 ...



Assessing Physical Activity in Persons with Rheumatoid Arthritis Using Accelerometry

  • Published on August 2010

Purpose: To empirically investigate if the nonwear threshold and the ‘valid day’ definition for accelerometer data from the general adult US population are appropriate for accelerometer data from persons with rheumatoid arthritis (RA). Methods: This study analyzed data from 107 persons with RA participating in the baseline (2006-2008) accelerometer assessment from ...


Do Activity Levels Increase After Total Hip and Knee Arthroplasty?

  • Published on Dec. 19, 2013

Background: People with osteoarthritis (OA) often are physically inactive. Surgical treatment including total hip arthroplasty or total knee arthroplasty can substantially improve pain, physical function, and quality of life. However, their impact on physical activity levels is less clear. Questions/Purposes: We used accelerometers to measure levels of physical activity ...


Relationship of Meeting Physical Activity Guidelines and Quality Adjusted Life Years

  • Presented on Oct. 27, 2013

Background/Purpose Regular physical activity is associated with reduced chronic disease burden and mortality. Recognizing the importance of physical activity, there are US federal guidelines for adults that also include persons with arthritis. Improving physical activity may be key to improving overall public health and reducing health care spending. Quality ...


Physical Activity and Physical Function in Older Adults With Knee Osteoarthritis

  • Published on Augus 6, 2013

Purpose: To assess correlates of physical activity, and to examine the relationship between physical activity and physical functioning, in 160 older (66 ± 6 years old), overweight/obese (mean body mass index = 33.5 ± 3.8 kg/m2), sedentary (less than 30 mins of activity, 3 days a week) individuals with knee osteoarthritis. Methods: Physical activity was measured with accelerometers ...


Association of pain with frequency and magnitude of knee loading in knee osteoarthritis

  • Published on July, 2011

Objective Although the relationship between pain and the magnitude of medial knee loading has been previously studied, the contribution of frequency of loading has not. The objective of this study was to determine whether the addition of loading frequency (steps/day) to loading magnitude (knee adduction moment [KAM] impulse) helps ...
