Twenty workers, consecutively attending the industrial health care centre for the first time with acute shoulder-neck pains, were subject to extensive rheumatological and ergonomic examinations. In seven patients congenital malformations for diseases causing musculoskeletal symptoms, or both, were probable aetiological factors. In the remaining 13 patients a significantly higher load was found ...

During the Apollo missions, unique locomotion strategies were adopted to efficiently move across the lunar surface (e.g. lunar loping). Bone mass maintenance is thought to be dependent on load bearing activity but it is unclear to what extent the partial gravity (1/6g) environment for the moon will be osteoprotective or how the gait profile of new methods of locomotion affect skeletal loads. In...

background: dairy farming work involves frequent use of poor postures. these postures may increase the risk of developing musculoskeletal disorders among dairy workers. objective: to assess postural load during performance of various tasks related to dairy farming. methods: this cross-sectional study was conducted on a dairy farm in iran. in order to assess postural load, tasks related to dairy...

background: musculoskeletal symptoms are the main cause of loss of working time, and increase in labor costs. poor posture is the most important risk factor for work-related musculoskeletal symptoms. this study aimed at evaluating the role of ergonomic risk factors in different surgical (open surgery, laparoscopy, and microsurgery) in the frequency or resonance frequency of musculoskeletal symp...

BACKGROUND Research suggests there is a high prevalence of anxiety and depression amongst patients with chronic musculoskeletal pain, which can influence the effectiveness of rehabilitation programs. It is therefore important for clinicians involved in musculoskeletal rehabilitation programs to consider screening patients for elevated levels of anxiety and depression and to provide appropriate ...

It has been suggested that the motor system may circumvent the difficulty of controlling many degrees of freedom in the musculoskeletal apparatus by generating motor outputs through a combination of discrete muscle synergies. How a discretely organized motor system compensates for diverse perturbations has remained elusive. Here, we investigate whether motor responses observed after an inertial...

BACKGROUND AND PURPOSE In this study, we examined changes in kinematic and electromyographic (EMG) measurements of the coordination (ie, the relative timing of joint movements and muscle activity) of a squat-lifting task in response to lifting increasing loads. SUBJECTS Fifteen male industrial workers served as a sample of convenience. METHODS Subjects lifted a weighted crate containing 15%...
