Movement generation is the complex result of the interaction between viscoelastic properties of muscle, inertial properties of the musculo-skeletal system and spatial trajectory planning. The Equilibrium Hypothesis (EP) may simplify the control of complex biomechanical model. It however do not solve a priori the problem of trajectory planning and on-line control of speech movements. The control...

Objectiv e- To eval uate the effects of Artemisia sieberi extract on experimental dermal wounds healing .Design- Experimental study.Animals- 30 male Spragne-Dawly rats.Procedures- Two uniform 7 mm diameter skin defect were created on the back of each animal by skinpunch (total of 60 wounds). Then, the extract of the plant was applied once daily on half of the wounds forhistopathological and bio...

Objective- To evaluate the healing potential of oleaster leave water soluble extract on skin wounds. Design- Experimental study. Animals- 30 male Spragne-Dawly rats, randomly assigned in two equal groups. Procedures- Under general anesthesia, and following surgical preparation, two uniform skin defects were made by 7mm skin punch. The water soluble extract was then applied on half of the wo...

Purpose. To evaluate correlation between tomographic gradation of keratoconus (KC) and its corresponding air-puff induced biomechanical response. Methods. Corneal tomography and biomechanics were measured with Scheimpflug imaging in 44 normal and 92 KC corneas. Deformation waveform was also analyzed with Fourier series. A custom KC severity scale was used from 1 to 3 with 3 as the most severe g...

During developmental stages, biomechanical stimuli on cardiac cells modulate genetic programs, and deviations from normal stimuli can lead to cardiac defects. Therefore, it is important to characterize normal cardiac biomechanical stimuli during early developmental stages. Using the chicken embryo model of cardiac development, we focused on characterizing biomechanical stimuli on the Hamburger-...

BACKGROUND Thoracic aortic rupture and aortopulmonary fistulation are rare conditions in horses. It mainly affects Friesian horses. Intrinsic differences in biomechanical properties of the aortic wall might predispose this breed. The biomechanical and biochemical properties of the thoracic aorta were characterized in warmblood horses, unaffected Friesian horses and Friesians with aortic rupture...

Perturbed biomechanical stimuli are thought to be critical for the pathogenesis of a number of congenital heart defects, including Hypoplastic Left Heart Syndrome (HLHS). While embryonic cardiomyocytes experience biomechanical stretch every heart beat, their molecular responses to biomechanical stimuli during heart development are poorly understood. We hypothesized that biomechanical stimuli ac...

[Purpose] Little is known about the effects of biomechanical foot orthoses in scoliosis, as determined by raster stereography. The objective of this study was to investigate the effect of individually manufactured biomechanical foot orthoses on scoliosis angle, trunk imbalance, and pelvic obliquity by comparing them with general insoles by using DIERS formetric 4 dimensional in patients with sc...

OBJECTIVE To investigate the effects of the system tilt and back recline angles on the biomechanics of wheelchair propulsion for a group of older, disabled patients. It was hypothesized that increasing both the system tilt and backrest recline angles would have a positive effect on the biomechanical efficiency of manual wheelchair propulsion. DESIGN Three kinetic variables were estimated duri...
