The prevalence and incidence of musculoskeletal disorders is high with computer workers, and poor sitting posture can be considered a factor contributing to low back discomfort. In the clinical literature, maintaining a neutral spinal curvature has been considered an optimal sitting posture. This study investigated the flexion and lateral flexion of trunk movements and trunk muscle activity dur...

OBJECTIVES: Subordinate status and submissiveness are stressful and are often associated with ill-health. However, when there is a physical or social threat posed by more powerful others, showing submissiveness may be a good strategy to avoid or terminate conflict. One way to show submissiveness is to assume a subordinate body posture, which may also help regulate one’s own stress responses by ...

With the aim of determining the connection between the indicators of body posture and latent structure of morphological variables in children aged 7 and 8 years, first and second grade of primary school, a set of 17 morphological measures and 12 body posture indicators were longitudinally applied to a sample of 110 boys and 114 girls. The latent structure of morphological variables in both sexe...

OBJECTIVE To develop work guidelines for wrist posture based on carpal tunnel pressure. BACKGROUND Wrist posture is considered a risk factor for distal upper extremity musculoskeletal disorders, and sustained wrist deviation from neutral at work may be associated with carpal tunnel syndrome. However, the physiologic basis for wrist posture guidelines at work is limited. METHODS The relation...

INTRODUCTION Foot disorders are common among older adults and may lead to outcomes such as falls and functional limitation. However, the associations of foot posture and foot function to specific foot disorders at the population level remain poorly understood. The purpose of this study was to assess the relation between specific foot disorders, foot posture, and foot function. METHODS Partici...

OBJECTIVES To determine the reliability and validity of the Saliba Postural Classification System (SPCS). METHODS Two physical therapists classified pictures of 100 volunteer participants standing in their habitual posture for inter and intra-tester reliability. For validity, 54 participants stood on a force plate in a habitual and a corrected posture, while a vertical force was applied throu...

PURPOSE Recurrent stone formers commonly present with calculi on the same side and the etiology of recurrent unilateral urolithiasis is unclear. Despite comprehensive metabolic evaluations, many patients will not be readily categorized into a treatable group. Data from the literature support that sleep posture may result in alterations of renal hemodynamics. We investigate the correlation of sl...

Proper execution of voluntary movement requires a sensorimotor transformation based on the initial limb state. For example, successfully reaching to a stable target requires the recruitment of different muscle groups depending on limb position at movement initiation. To test whether this transformation could occur at the spinal level, we stimulated the cervical spinal cord of anesthetized monke...

INTRODUCTION Body posture is an individual characteristic for everyone, it shows great differentiation - especially in people during their progressive development. As a result, the variability of the development and lack of physical activity impose body posture defects in children and youth. In the literature there is a great lack of measureable data on the relations between correct body postur...

BACKGROUND AND PURPOSE Poor sitting posture has been implicated in the development and perpetuation of neck pain symptoms. This study had 2 purposes: (1) to compare change in cervical and thoracic posture during a distracting task between subjects with chronic neck pain and control subjects and (2) to compare the effects of 2 different neck exercise regimens on the ability of people with neck p...
