Of one hundred patients originally entered for this trial eighty-three with acute musculo-skeletal disorders were treated with either naproxen sodium (SYNFLEX, Syntex), 550 mg initially followed by 275 mg four times daily, or piroxicam (FELDENE, Pfizer), 20 mg twice daily for two days then 20 mg once daily. Patients were assessed at admission, on day 4 and on day 8. Pain on passive movement, te...

Detailed characterization of damage and rupture mechanics of arteries is one the current challenges in vascular biomechanics, which requires developing suitable experimental approaches. This paper introduces an approach using in situ tensile tests in an X-ray micro-tomography setup to observe mechanisms of damage initiation and progression in medial layers of porcine aortic samples. The techniq...

An investigation was made on the relationship between music practice and musculo-skeletal disorders among piano students, with the main aim of developing health education programmes that would improve the performance and health of the students. The investigation covered three areas: (a) Analysis of study organization and main musculo-skeletal complaints achieved by a questionnaire distributed t...

Locomotion is a behaviour resulting from the interaction of the nervous and muculo-skeletal systems and the environment. However the musculo skeletal systems of some terrestrial mammals present an intrinsic ability to realize a dynamic stable locomotion. Actual anthropomorphic passive walkers demonstrate that a pure mechanical system with leg and arms is able to walk down an inclined plane. Num...

Globally, there are an estimated 605 million people aged 60 years and above. Improvements in health care facilities have brought longevity, which is considered to be one of the greatest achievements of the 20 century. Objectives: To assess the morbidity pattern in geriatric people. Methodology: A community based cross sectional study. Results: Out of 208 aged 91 (43.7%) were males, 117 (56.25%)...

The mechanics of defecation and fecal continence are poorly understood. Valvular theories for continence 2 rely on raised intra-abdominal pressure to force the anterior wall of the rectum downwards to close off the anorectal junction. Such theories are not consistent with EMG and radiological data which suggest a striated muscle sphincteric mechanism.3 It has been demonstrated that puborectalis...

The assessment of musculo-articular stiffness (MAS) with the free-oscillation technique is a popular method with a variety of applications. This study examined the sources of variability (load applied and frequency of oscillation) when MAS is assessed. Over two testing occasions, 14 healthy men (27.7±5.2 yr, 1.82±0.04 m, 79.5±8.4 kg) were measured for isometric maximum voluntary contraction and...

Human and animal movement is absolutely fascinating and can hardly be mimicked by technical devices, so far. It has been proposed that part of the movement generation and control can be associated to the non-linear characteristics of the bio-mechanical structures and morphology. Terms like morphological computation (Paul, 2006) and intelligence by mechanics (Blickhan et al., 2007) capture this ...
