Based on a general methodology using natural co-ordinates, a three-dimensional whole body response model for the articulated human body is presented in this paper. The joints between biomechanical segments are defined by forcing adjacent bodies to share common points and vectors that are used in their definition. A realistic relative range of motion for the body segments is obtained introducing...

Mounting evidence connects the biomechanical properties of tissues to the development of eye diseases such as keratoconus, a common disease in which the cornea thins and bulges into a conical shape. However, measuring biomechanical changes in vivo with sufficient sensitivity for disease detection has proved challenging. Here, we present a first largescale study (~200 subjects, including normal ...

PURPOSE The biomechanical environment within the optic nerve head (ONH) may play a role in retinal ganglion cell loss in glaucomatous optic neuropathy. This was a systematic analysis in which finite element methods were used to determine which anatomic and biomechanical factors most influenced the biomechanical response of the ONH to acute changes in IOP. METHODS Based on a previously describ...

Older adults demonstrate increased amounts of postural sway, which may ultimately lead to falls. The purpose of this systematic review was to investigate the effect of different foot orthoses on lower limb biomechanical variables, lower limb muscular activity, and balance in elderly people. Examining texts based on the search on the Magiran, Google Schoolar, Pubmed, Scopus, and SIVILICA sites w...
