background: although upper-extremity disability correlates with psychosocial aspects of illness the association with sleep disturbance in upper extremity disability is less certain. to evaluate whether sleep disturbance is associated with upper-extremity disability among patients with upper extremity illness, accounting for sociodemographic, condition-related, and psychosocial factors. methods:...

The foot is an engineering marvel that allows the body to perform many physical activities over a wide variety of terrain with remarkable efficiency. The functions of the foot and the lower extremity are biomechanically integrated; thus normal lower-extremity function requires normal foot function and vice versa. Because the subtalar joint is the main pedal joint allowing the triplanar translat...

BACKGROUND There are relatively few standard, objective measures for studying physical function among older adults with multiple sclerosis (MS), yet such measures are necessary considering the shift in prevalence and associated consequences of both MS and older age on physical function. We undertook a preliminary examination of the construct validity of Short Physical Performance Battery (SPPB)...

BACKGROUND Age-related hyperkyphosis has been associated with poor physical function and is a well-established predictor of adverse health outcomes in older women, but its impact on health in older men is less well understood. METHODS We conducted a cross-sectional study to evaluate the association of hyperkyphosis and physical function in 2,363 men, aged 71-98 (M = 79) from the Osteoporotic ...

BACKGROUND Age-related declines in lean body mass appear to be more rapid in men than in women but our understanding of muscle mass and function among different subgroups of men and their changes with age is quite limited. The objective of this analysis is to examine racial/ethnic differences and racial/ethnic group-specific cross-sectional age differences in measures of muscle mass, muscle str...

BACKGROUND Meat is an important source of high-quality protein and vitamin B but also has a relatively high content of saturated and trans fatty acids. Although protein and vitamin B intake seems to protect people from functional limitations, little is known about the effect of habitual meat consumption on physical function. The objective of this study was to examine the prospective association...

Background: We compared the amount of variation in Patient-Reported Outcomes Measurement Information SystemPhysical Function (PROMIS PF) Computer Adaptive Test (CAT) accounted for by The Tampa Scale for Kinesiophobia(TSK) and its short form (TSK-4) independent of other factors. Questionnaire coverage, reliability, and validitywere compared for both TSK and TSK-4 using mean sca...

BACKGROUND Little is known regarding the longitudinal effects of back pain on physical function among older persons. We sought to determine whether back pain leading to activity restriction (i.e., restricting back pain) is associated with decline in lower extremity physical function among community-dwelling older persons. METHODS In this prospective study with an 18-month follow-up period, pa...

Background. Extremity sarcoma represents a heterogeneous group of rare cancers that carries a relatively high morbidity with regards to physical function. Quality of Life (QoL) as an outcome is an important consideration in this cohort. We aimed to identify the correlates of QoL in extremity sarcoma cohorts. Methods. A systematic review of the literature on extremity sarcoma in adults from five...
