Objective To determine if there is muscle mass reduction in patients with ankylosing spondylitis (AS) compared to the general population and to examine the relationship between skeletal muscle mass, quality of life (QOL), strength, and mobility in patients with AS. Methods A total of 30 AS patients were enrolled in this study. Skeletal muscle mass was measured by bioelectrical impedance analysis, and it was expressed as the skeletal muscle mass index (SMI). QOL was assessed using the EuroQOL (EQ-5D). To measure mobility, the …

Background The phase angle (measured via bioelectrical impedance analysis [BIA]) is an indicator of cell membrane function and used for prognostic evaluation of diseases. Locomotive syndrome (LS) has been advocated in the evaluation of physical ability. This study aimed to determine the relationship between LS and the phase angle as well as muscle mass, muscular strength, and motor function. Methods In this prospective cohort study, 541 patients undergoing a health checkup participated. All participants were …

… However, in contrast to other tests, handgrip strength is not directly dependent on the symptoms of spinal stenosis, but rather reflects generalized muscle strength. Therefore, our results suggest a possible association between generalized muscle weakness and the pathogenesis of LSS. Handgrip strength was the only factor that was correlated with both ODI and QOL in the LSS group. A comprehensive understanding of the mechanism that explains the relationships among handgrip strength, back pain, and QOL is yet to be reached … Therefore, although it is impossible to attribute …

To assess the relationship of total fat mass (TFM) and total lean mass (TLM) with bone mineral density (BMD) and bone mineral content (BMC), we studied 770 postmenopausal white women after total body measurements by dual-energy X-ray absorptiometry. Height-independent bone mineral density (HIBMD) was also tested. The effects of TFM and TLM on the dependent variables HIBMD, BMD, and BMC were assessed by the univariate general linear model (UGLM). Age, age at menopause, height, and bone area were entered in the …

This study aimed to investigate the characteristics of skeletal muscle mass, muscle strength, and physical performance among community-dwelling older women. Data were collected from 306 older adults, and the data of 214 older women were included in the final analysis. Participants' calcaneus bone mass was measured using ultrasonography. Based on their T-scores, participants were divided into the following three groups: normal (T-score>− 1), low (− 2.5< T-score≤− 1), and very low (T-score≤− 2.5) bone mass. Further, participants' …

Purpose To evaluate knee strength, ligament stability, and functional outcomes in patients older than 50 years who underwent anterior cruciate ligament (ACL) reconstruction, and to compare these results with those obtained from a younger patient group (< 40 years). Methods Forty patients older than 50 years and 50 patients younger than 40 years who underwent ACL reconstruction were retrospectively studied. Isokinetic extensor and flexor muscle strength were evaluated. The peak torque was determined at speeds of 60°/s and …

Body weight is positively associated with bone mineral density but the relationship between obesity and bone mineral density is unclear. Leptin and adiponectin are potential independent contributors to bone mineral density. We assessed the correlations of body …

Background Bone mineral density (BMD) is influenced by many factors. Despite the reported association between body components and BMD, most of these studies investigated the relationship between absolute muscle mass or fat mass and BMD in postmenopausal women or elderly subjects. The aim of this study is to investigate the association between muscle mass deficits (MMD) estimated from bioelectrical impedance analysis (BIA) and lumbar spinal BMD in Korean adults 20 to 49 years of age. Methods This cross-sectional …

ABSTRACT BACKGROUND AND OBJECTIVES: This study is necessary considering the expressive number of rural workers that are not assisted by a health professional despite the presence of musculoskeletal changes such as low back pain. Thus, the objective was to check if there is a relationship among low back pain levels, anthropometric measures and range of motion of rural workers. METHODS: A cross-sectional study with rural workers that used the visual analog scale to measure low back pain. The data on body mass index, fat …

Longitudinal studies on bone mass decline for healthy women are sparse. We performed a retrospective longitudinal study to evaluate the factor associated with bone mass changes at the lumbar spine in healthy Korean pre-and perimenopausal women over the age of 40. We examined the relation of blood tests including thyroid function tests at baseline and follow-up to the annual percentage changes in average BMD of L2-L4 (A% ΔLSBMD). Four hundred and forty-three subjects without diseases or medications pertaining to bone metabolism …
