In 2 experiments, participants stood upright with their eyes open or closed and fating forward or to the side; the 2nd experiment also included a manipulation of optical structure. At issue were the effects of different conditions of visual exproprioperception on motions of the body's center of pressure. Also at issue was the utility of 2 characterizations of postural control under the vision m...

We compared anteroposterior and mediolateral range of motion and velocity of the center of pressure (COP) on the horse's back between riders without disabilities and riders with cerebral palsy. An electronic pressure mat was used to track COP movements beneath the saddle in 4 riders without disabilities and 4 riders with cerebral palsy. Comparisons between rider groups were made using the Mann-...

By proposing efficient methods for estimating Body Segment Inertial Parameters' (BSIP) estimation and validating them with a force plate, it is possible to improve the inverse dynamic computations that are necessary in multiple research areas. Until today a variety of studies have been conducted to improve BSIP estimation but to our knowledge a real validation has never been completely successf...

background: perfectionism is a character of personality thatindicates striving  to be perfect  and having  high standards for practice .it is a tendency to evaluate one' s andothers behavior critically. aim of this study was investigating theeffectiveness of quality of life therapy on the perfectionism.methods: this was a semi experimental research with pretest andposttest with control group.  ...

introduction: hypertension as a major coronary artery disease (cad) risk factor is more prevalent in iran. in recent years, the effect of antioxidants in reducing cad and their risk factors has been considered. therefore, this triple blind placebo-controlled clinical trial was performed to determine the effects of antioxidant vitamin e on blood pressure in patients with mild hypertension. mater...

Background: Smoking is one of the preventable causes of disease in middle and low-income countries. This study was conducted in smokers and non-smokers to observe the changes in total count of leukocytes in cigarette smokers in relation to body mass index (BMI) and blood pressure (BP). Methods:The study populations were from different sources including diagnostic center and general hospital, an...

Three-dimensional simulations of the single-phase laminar flow and forced convective heat transfer of water in microchannels with small rectangular sections having specific hydraulic diameters and distinct geometric configurations were investigated numerically. The numerical results indicated that the laminar heat transfer was to be dependent upon the aspect ratio and the ratio of the hydraulic...

introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been  introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the  substitution  of  the  blood  pressure  changes  in  the  central  arteries  such  as  carotid  with  the  blood  pressure  changes in the brachial results in error in the blood...
