OBJECTIVE To determine if low frequency (≤100 Hz) pulsed subsensory threshold electrical stimulation produced either through pulsed electromagnetic field (PEMF) or pulsed electrical stimulation (PES) vs sham PEMF/PES intervention is effective in improving pain and physical function at treatment completion in adults with knee osteoarthritis (OA) blinded to(More)
The object was to assess whether cross-sectional area (CSA) and water diffusion properties of leg muscles in young and older women change with increased time spent in supine rest. Healthy young (n = 9, aged 20–30 years) and older (n = 9, aged 65–75 years) women underwent MRI scanning of the right leg at baseline, 30 and 60 min of supine rest. Muscle CSA was(More)
Hyperkyphosis is a common spinal disorder in older adults, characterized by excessive forward curvature of the thoracic spine and adverse health outcomes. The etiology of hyperkyphosis has not been firmly established, but may be related to changes that occur with aging in the vertebrae, discs, joints, and muscles, which function as a unit to support the(More)
The objective of this study was to estimate the associations between muscular fat infiltration, tibia bone mineral quantity and distribution, and physical function in healthy older women. Thirty-five women (aged 60–75 years, mean 70 years) were recruited from the community. Percent intramuscular fat (%IntraMF) within the right leg tibialis anterior, soleus,(More)
The association between posture and physical function during daily activities in people at risk for osteoporotic fracture is not clear. We report the reliability of measuring posture using the digital inclinometer and how these measures relate to performance-based and self-reported physical function. This study aims to determine the reliability of a simple(More)
The International Classification of Functioning, Disability and Health (ICF) framework facilitates systematic assessment of functioning across four components. ICF Core Sets are proposed to be beneficial for clinicians in multidisciplinary care settings because they provide a common language for communication. A clinical vignette of a postmenopausal woman(More)
Background Hyperkyphosis reduces the amount of space in the chest, mobility of the rib cage, and expansion of the lungs. Decline in pulmonary function may be greater in persons with more severe kyphosis; however, no prospective studies have assessed this association. We conducted a longitudinal study to quantify the impact of kyphosis severity on decline in(More)
OBJECTIVE To evaluate the association between thoracic kyphosis and physical function. DESIGN Prospective cohort. SETTING Framingham, Massachusetts. PARTICIPANTS Framingham Heart Study Offspring and Third Generation cohort members who had computed tomography (CT) performed between 2002 and 2005 and physical function assessed a mean 3.4 years later (N(More)
Skeletal muscle is one of the larger organs of the body and is integrally involved in metabolic processes in both health and disease. The ability to accurately and precisely measure skeletal muscle structure is essential for understanding the changes that occur naturally over the lifespan as well as those observed in chronic disease, and in response to(More)
