BACKGROUND Obesity associated with joint pain of the lower extremities is likely due to excessive mechanical load on weight bearing joints. Additional mechanical factors may explain the association between obesity and joint pain. FINDINGS We characterized the association between obesity and non-traumatic lower extremity (LE) joint pain in adolescents and examined the modifying effect of hyper...

Pregnancy induces numerous modifications in the musculoskeletal system of female body. Since one essential roles lumbopelvic structure is to support mechanical loads upright position, this study was designed simulate response complex growing foetus pregnant women. The authors hypothesized that posture (i.e., lordosis and muscle involvement) under pregnancy conditions might be adjusted minimize ...

Objectives. Overweight negatively affects musculoskeletal health; hence obesity is considered a risk factor for osteoarthritis and chronic low back pain. This was conducted to determine if obesity affects neuropathic pain, usually considered unrelated to the weight-load on the musculoskeletal system. Methods. Using a cut-off body mass index value of 25, 44 patients with neuropathic pain were gr...

abstract background and purpose: work-related musculoskeletal disorders (wmsds) are a group of painful disorders of muscles, tendons, and nerves. carpal tunnel syndrome, tendonitis, thoracic outlet syndrome, and tension neck syndrome are examples. almost all work requires the use of the arms and hands, therefore, most wmsd affect the hands, wrists, elbows, neck, and shoulders. the aim of the cu...

This study presents a pilot investigation into the effectiveness of unloader knee braces for osteoarthritis subjects. The unloading effect of the brace was modeled by applying a knee abduction moment as a function of the brace deflection angle, eliminating the need for load sensors on the knee brace. The use of a detailed musculoskeletal model provided the means to evaluate the relative importa...

Occupational Health has been annually organized with the objective of making a contribution to the advancement of occupational health through academic and practical knowledge exchanges in the field as well as fostering the friendship among Japan, Korea and China. collaborated to make it successful 1). In 2000, China officially joined the conference with the approval of the steering committee an...

This study investigated the impact of body armor weight and load magnitude and distribution on the lower extremities during walking. Range of motion (ROM) was assessed while seven healthy, male, right-handed, military university students walked while wearing seven different garments of varying weights (0.06 kg, 9 kg, 18 kg, and 27 kg) and load distributions. Decreased pelvic rotation found with...

Ten fishermen aged between 19 and 48 years of age, were examined in the field during inland fishing activity, which they perform individually. Physiological strain in terms of heart rate varied between 86 and 115 beats/min with mean net cardiac cost of 32 beats/min. The average relative cardiac cost was 36%. Analysis of physiological responses revealed that the recommended limits of cardiac str...

The purpose of this prospective cohort study was to investigate physical, occupational, and psychosocial risk factors for musculoskeletal injuries (MSI) in deployed female soldiers. Before deployment, participants completed performance testing and surveys and after deployment an additional survey detailing occupational demands and MSI. Data analyzed found 57/160 (36%) suffered 78 MSI. In unadju...
