background: driving posture discomfort can contribute to musculoskeletal disorders (msds), injuries, lumbar pain and fatigue. the three main objectives of this study were to identify the level of awareness for correct and safe driving posture, health implication to their body parts and to propose a suitable car seat fit dimensions appropriate for malaysian drivers’ population. methods: the two ...

Musculoskeletal pain is commonly reported by police officers. A potential cause of officer discomfort is a mismatch between vehicle seats and the method used for carrying appointments. Twenty-five police officers rated their discomfort while seated in: (1) a standard police vehicle seat, and (2) a vehicle seat custom-designed for police use. Discomfort was recorded in both seats while wearing p...

[Purpose] We assessed the effects of a suspension seat support chair on the trunk flexion angle and gluteal pressure during computer work. [Subjects] Ten males were recruited. [Methods] The suspension seat support was developed to prevent abnormal gluteal pressure and a slumped sitting posture during computer work. The gluteal pressure was measured with a TekScan system and the trunk flexion an...

Although the hype surrounding the promise of electronic commerce seems all pervasive currently, there is an absence of research on automobile eCommerce, especially in developing countries, which covers wide-ranging issues beyond contextual imperatives. This paper tries to fill in the gap, by analyzing the impacts of eCommerce on automobile industry in China, and the factors of eCommerce adoptio...

The identification of chair rise phases is a prerequisite for quantifying sit-to-stand movements. The aim of this study is to validate seat-off and seat-on detection using a single-body-fixed sensor against detection based on chair switches. A single sensor system with three accelerometers and three gyroscopes was fixed around the waist. Synchronized on-off switches were placed under the chair....

BACKGROUND Increasing seat belt use represents an ideal opportunity for preventive health care in family practice. Little evidence exists, however, that primary care physicians can increase safety belt use. METHODS Three hundred twenty-six patients seen in a rural primary care center were randomized to either a control or intervention group. Before their health care examination, patients comp...

Background Active 'hands-on' participation in the 'hot-seat' during immersive simulation-based training (SBT) induces stress for participants, which is believed to be necessary to improve performance. We hypothesized that observers of SBT can subsequently achieve an equivalent level of non-technical performance as 'hot-seat' participants despite experiencing lower stress. Methods We randomize...

OBJECTIVE To investigate the effects of body mass composition and cushion type on seat-interface pressure in spinal cord injured (SCI) patients and healthy subjects. METHODS Twenty SCI patients and control subjects were included and their body mass composition measured. Seat-interface pressure was measured with participants in an upright sitting posture on a wheelchair with three kinds of sea...

OBJECTIVES The objective was to determine the association between the abdominal seat belt sign and intra-abdominal injuries (IAIs) in children presenting to emergency departments with blunt torso trauma after motor vehicle collisions (MVCs). METHODS This was a planned subgroup analysis of prospective data from a multicenter cohort study of children with blunt torso trauma after MVCs. Patient ...

[Purpose] This study was aimed at investigating the influence of seat height and body posture on the activity of the superior trapezius and longissimus muscles. [Subjects and Methods] Twenty two healthy subjects were instructed to perform a total of eight different body postures, varying according three main factors: seat height (low and high seat); trunk inclination (upright and leaning forwar...
