The real-time estimation of muscle forces could be a very valuable tool for rehabilitation. By seeing how much muscle force is being produced during rehabilitation, therapists know whether they are working within safe limits in their therapies and patients know if they are producing enough force to expect improvement. This is especially true for rehabilitation of Achilles tendon ruptures where,...

BACKGROUND Musculoskeletal disorders are prevalent and represent the most common health problem among the working population in industrially-developing countries, with considerable costs and impact on quality of life. Despite the high incidence of disability insurance claims among Brazilian manufacturing-sector workers, only a few studies assessed musculoskeletal disorders prevalence. OBJECTI...

Purpose – This paper focuses on an engineering application of the vertebrate musculoskeletal system. The musculoskeletal system has unique mechanisms such as bi-articular muscle, antagonistic muscle pairs and muscle-tendon elasticity. The “Artificial Musculoskeletal System” is achieved through the use of the pneumatic artificial muscles. The study provides a novel method to describe the force p...

Let Γ be a 3-dimensional Kleinian punctured torus group with accidental parabolic transformations. The deformation space of Γ in the group of Möbius transformations on the 2-sphere is well-known as the Maskit slice M1,1 of punctured torus groups. In this paper, we study deformations Γ of Γ in the group of Möbius transformations on the 3-sphere such that Γ does not contain screw parabolic transf...

[Purpose] The purpose of this study was to establish the reliability and validity of the Short Musculoskeletal Function Assessment questionnaire, which was translated into Korean, for patients with musculoskeletal disorder. [Subjects and Methods] Fifty-five subjects (26 males and 29 females) with musculoskeletal diseases participated in the study. The Short Musculoskeletal Function Assessment q...

This paper proposes methods and technologies that advance the state of the art for modelling the musculoskeletal system across the spatial and temporal scales; and storing these using efficient ontologies and tools. We present population-based modelling as an efficient method to rapidly generate individual morphology from only a few measurements and to learn from the ever-increasing supply of i...

BACKGROUND In the literature there are discussions on the choice of outcome and the need for more longitudinal studies of musculoskeletal disorders. The general aim of this longitudinal study was to analyze musculoskeletal neck pain, in a group of young adults. Specific aims were to determine whether psychosocial factors, computer use, high work/study demands, and lifestyle are long-term or sho...

AIMS (1) To determine the proportion of children evaluated for musculoskeletal pain in a paediatric primary care clinic over a three year period; (2) to describe the number of office visits due to musculoskeletal pain; (3) to categorise the more common presenting complaints; and (4) to characterise the aetiology of musculoskeletal pain in a paediatric primary care clinic. METHODS Retrospectiv...

The model of volumetric material growth is introduced in the framework of finite elasticity. The new results obtained for the model are presented with complete proofs. The state variables include the deformations, temperature and the transplant matrix function. The wellposedness of the proposed model is shown. The existence of local in time classical solutions for the quasistatic deformations b...

This paper presents a comparison of learning methods to detect stress from video sequences of people with a close-up of their face. The video sequences consist of people subjected to various psychological tests that induce high and low stress situations. We use a model-based tracking system to get the face movements and deformations in a parameterized form. We compare different learning methods...
