Changes in the skin temperature (Tsk) are known to be connected with diseases and subsequently infrared thermography (IRT) has been proposed to be a diagnostic aid, e.g. in musculoskeletal disorders (MSD). However, mostly due to conflicting results of previous studies, IRT lost credibility. Now interest in IRT is growing again but valid methodological studies are needed in order to avoid new di...

Construction workers face more health issues compared to the other workers. And cost compensation for injuries of are also beyond limit. Continuous and long-term exposure body parts construction may lead occurrence Work-Related Musculoskeletal Disorder. WMSD is a group painful disorders muscles, tendons, nerves. This study deals with analysis primary residential works. Objective: To analyse pre...

BACKGROUND Stability or changes of health behaviours have not been studied in association with incidence of disability pension (DP). The aims were to (1) investigate if stability or changes in health behaviours predict DP due to musculoskeletal diagnosis (MSD), (2) to evaluate if an association exists for DP in general, and (3) after taking familial confounding into account. METHODS The study...

Motor-manual felling and wood processing is a high-risk work process where the chainsaw, in connection to other variables working environment, key constant source of risk danger for forest chainsaw operators. Pursuant foregoing, purpose this research investigate compare detected musculoskeletal disorder (MSD) symptoms among workers Croatia according their employer (state company – Hrvatske šume...

Background: Work-related musculoskeletal disorders are the most important problems in the health workforce. These discomforts cause many working days losses, increase absenteeism from work, and impose annual economic costs. Awkward posture is the most important factor among the risk factors for work-related musculoskeletal disorders. This study aimed at implementing an interventional ergonomic ...

We consider a nonpreemptive single-machine scheduling problem to minimize mean squared deviation of job completion times about a common due date with maximum tardiness constraint (MSD/Tmax problem), where the common due date is large enough so that it does not constrain the minimization of MSD. The MSD/Tmax problem is classi®ed into three cases according to the value of maximum allowable tardin...

Background: We studied musculoskeletal diseases (MSD) and injuries among fishermen and seamen with focus on low back disorders, carpal tunnel syndrome (CTS), rotator cuff syndrome and arthrosis. Methods: Cohorts of all male Danish seamen (officers and nonofficers) and fishermen employed 1994 and 1999 with at least six months employment history were linked to the Occupational Hospitalisation Reg...

OBJECTIVE The use of hand held devices (HHD) such as mobile phones, game controls, tablets, portable media players and personal digital assistants have increased dramatically in past decade. While sending a text message or using the controls of the HHD the users need to use their thumb and other palm muscles extensively. The objective of this study was to describe the risk factors and clinical ...
