abstract background: mental workload is a general concept in the literature of ergonomics and human factors that are affected by external working demands, environmental, psychological and organizational factors, organizational and mental abilities. the aim of this study was to assess the mental workload and its impact on musculoskeletal disorders among nurses employed at different parts of the ...

Computer models of the musculoskeletal system are broadly used to study the mechanisms of musculoskeletal disorders and to simulate surgical treatments. Musculoskeletal models have historically been created based on data derived in anatomical and biomechanical studies of cadaveric specimens. MRI offers an abundance of novel methods for acquisition of data from living subjects and is revolutioni...

Musculoskeletal ultrasound (US) can serve as an excellent imaging modality for the musculoskeletal clinician. Although MRI is more commonly ordered in the United States for musculoskeletal problems, both of these imaging modalities have advantages and disadvantages and can be viewed as complementary rather than adversarial. For diagnostic US, relative recent advances in technology have improved...

background: today, the prevalence of musculoskeletal disorders is one of the health issues of concern in any society. one of the main causes of musculoskeletal disorders and conditions can be named unpleasant working conditions. the aim of this study was to report the prevalence of musculoskeletal disorders including working postures and lifting-related musculoskeletal disorders among workers o...

background sarcoidosis is a multisystem disease affecting different organs with different frequency rates depending on geographical location. musculoskeletal abnormalities includes osseous lesions (small and large bone sarcoidosis), sarcoidal arthropathy, and sarcoidal myopathy. musculoskeletal involvement is reported in a significant number of patients. objectives this study aimed to determine...

background: the impact of work-related musculoskeletal disorders (wrmsds) on functional performance of nigerian welders is unknown. this study investigated the prevalence, pattern and impact of wrmsds on functional efficiency among welders in alimosho local government, lagos state, nigeria.   materials and methods: this cross sectional survey involved 177 welders in a rural-urban area in nigeri...

OBJECTIVE Worldwide, the use of sonography for the evaluation of the musculoskeletal system has been growing. However, radiologists in North America have been relatively slow to incorporate musculoskeletal sonography into their practices. The purpose of this article is to show the advantages of musculoskeletal sonography. CONCLUSION Musculoskeletal sonography is an important complementary too...

Background Musculoskeletal problems are common in children. The majority are self-limiting and related to trauma; however the symptoms can be feature of serious medical conditions. It has been previously shown that musculoskeletal examination is poorly documented. Musculoskeletal examination is a station on the RCPCH clinical exam. Teaching resources on how to perform musculoskeletal examinatio...

Research indicates that, despite physiotherapists’ comprehensive training in the basic sciences, manipulative (currently “musculoskeletal”) therapy is still dominated in the clinical setting by its original, now obsolete, structure-based “biomedical” model. This is further inexplicable in the light of evidence that not only the underlying “philosophy” but also several of the fundamental require...

Recent studies have shown that the constant inertia assumption made in typical muscle dynamic models can lead to significant discrepancies in accuracy of simulation or inverse dynamics. This paper proposes a general framework for musculoskeletal dynamic simulation that takes into account changes in muscle inertia that occur during movement. We first develop a general shape-varying muscle mass m...
