105 دانشجو شامل 50 دختر و 55 پسر با دامنه سنی 18 تا 35 سال (30/3+-88/21) در این تحقیق شرکت کردند. هدف از این تحقیق عبارت بود از: الف) تعیین هنجارهای سه تست بالینی واکنش تعادلی شامل tilt board tip (tbt) و flat board reach (fbr) و tilt board reach (tbr) ب) مقایسه واکنشهای تعادلی در دختران و پسران این سه تست بر روی آزمودنیهای انجام گرفت و چهار زاویه زیر اندازه گرفته شد: زاویه بین تخته ...
هدف: تحقیقات بر روی tilt board که اختصاصاً جهت تمرینات تعادلی طراحی گشته بسیار محدود است. هدف ما در این مطالعه بررسی اثر تمرین با tilt board بر مولفه های استاتیک و دینامیک تعادل بعد سکته بود. روش: در این مطالعه ?? بیمار همی پلژی شرکت داشتند که بطور تصادفی به دو گروه مداخله و کنترل دسته بندی شدند. بیماران با استفاده از آزمون های کلینیکی، دستگاه force plate و biodex قبل و بعد درمان مورد ارزیابی ...
measurements of the tilt angle of potential fields can be a useful aid to their interpretation. there are several varieties of the methods in use, such as tilt angle, and the derivative of tilt angle. tilt angle filters are used for exact edge detection of the rectangular bodies artificially by writing a matlab code. the gravity effects of these models are computed by standard algorithms. the e...
Background and Aims: Accurate bone measurements are essential for determining the optimal size and length of proposed implants. The radiologist should be aware of the head position effects on image dimensions in each imaging technique. The purpose of this study was to evaluate the effect of mandibular plane angle on image dimensions in linear tomography.Materials and Methods: In this in vitro s...
The orientation of the flat solar collectors affects the amount of solar radiation received and absorbed by them. In this study, the optimum tilt angles of flat plat solar collectors in Kashan for the fixed monthly, seasonal, semi-yearly and yearly adjustments have been determined. If the solar calculations are based on the measured data, they produce more accurate results however in many parts...
Background & Aim: Magnetic resonance imaging(MRI) in the coronal plane before and after contrast is currently considered to be the most specific and sensitive technique for imaging pituitary gland. However, because of the false negative results of this method in the detection of pituitary microadenomas and the importance of finding these microadenomas, infundibular deviation or tilt in MRI ...
purpose: controversy has recently risen about the presence of compensatory ocular countertorsion (coct) after head tilt. this study was performed to define the functional range of this phenomenon. methods: cycloplegic autorefraction was performed on 80 eyes with regular astigmatism 2d. objective autorefraction was performed in normal position, right and left head tilt positions of 5º, 10º, 15º,...
Introduction: Using backpacks has arisen complaints regarding musculoskeletal pains among students. The aim of this study is to investigate the relationship between demographic information and bag weight with Neck Disability Index (NDI), angles and head and neck postures among students. Material and Methods: This descriptive-analytical and cross-sectional study was conducted among 80 students ...
In this paper, the application of D-optimal models, as an alternative to response surface models (RS models) for design of experiment (DOE) was examined. Two D-optimal models for tilt-rotors in the wind tunnel experiment, as a form of quadratic functions, were generated based on a chosen optimality criterion. This optimality criterion was used to generate the optimized sampled points in the des...
