High, sustained loads in masonry cause time-dependent deformations, which can lead to failure of the construction. This phenomenon mostly occurs in high constructions, such as historical towers, where the dead load imposes significant stresses on the base of the tower [4]. As knowledge and experimental data are lacking to describe this time-dependent behavior in historical masonry, a research p...

Background & Aims of the Study: Musculoskeletal disorder (MSD) is one of the most serious consequences of improper posture or work-related strain with Symptoms of pain in one or more regions of the body. Repeated long-term work-related load can be considered as the main cause of ULWMSDs. This study was aimed to do ergonomic assessment in a manufacturing company in Kashan city u...

The purpose of this review is to name and describe the important factors of musculoskeletal strain originating from pushing and pulling tasks such as cart handling that are commonly found in industrial contexts. A literature database search was performed using the research platform Web of Science. For a study to be included in this review differences in measured or calculated strain had to be i...

Loading/unloading a ladder on vehicles are frequent tasks and involve overhead handling that may expose workers to risk factors of shoulder musculoskeletal disorders. The objective of the present study was to evaluate posture, forces required and perceived exertion when loading and unloading the ladder on a utility truck. Thirteen male overhead line workers from an electric utility in Brazil pa...

Musculoskeletal injuries are a common occurrence in military service members. It is believed that the load carried by the service member impedes stability and alters back and pelvis kinematics, increasing their susceptibility to musculoskeletal injuries, specifically in the lower extremities. The purpose of this study was to examine the effects of two different loads on postural sway, forward t...

BACKGROUND Musculoskeletal disorders (MSDs) are a serious problem among the nursing staff. Mental workload is the major cause of MSDs among nursing staff. The aim of this study was to investigate the mental workload dimensions and their association with MSDs among nurses of Alzahra Hospital, affiliated to Isfahan University of Medical Sciences. MATERIALS AND METHODS This descriptive cross-sec...

AIMS To examine the dimensionality, internal consistency, and construct validity of a new physical workload questionnaire in employees with musculoskeletal complaints. METHODS Factor analysis was applied to the responses in three study populations with musculoskeletal disorders (n = 406, 300, and 557) on 26 items related to physical workload. The internal consistency of the resulting subscale...

OBJECTIVES To describe the prevalence of self reported musculoskeletal complaints in the back, arms or neck, and legs among workers in the spinning industry, and to investigate the relations between these complaints and work related variables. METHODS An interview based questionnaire survey was carried out in two spinning industry factories in Lithuania. RESULTS The study group consisted of...

OBJECTIVE Our aim was to determine the most common musculoskeletal diseases, depending on the type of sports and athletes' age. METHODS The results of examination of 976 athletes aged from 16 to 42 years (average age - 28,9±2,3) with musculoskeletal diseases were analyzed. Medical diagnostic procedures included clinical, laboratory, instrumental (radiography, magnetic resonance imaging, ultra...
