normal range of joint motion is an important factor in joint examination in clinical practice which is related to factors such as age, sex and geographic region. there is no data in the literature on the range of joint motions in healthy iranian adults. we studied joint motions in 100 healthy volunteer subjects, 49 men and 51 women, from 19 and 58 years of age. the joint mobility was examined i...

This paper presents a parametric, two-dimensional random field with Markov properties and variable structure that is useful for statistically modeling ensembles of images and for generating pseudo-random images with desired stochastic and visual properties. The Variable Structure Random Field (VSRF) model has six parameters which provide a high degree of control over the random field statistics...

The presence of trace metal cadmium assay was investigated with a copper immobilized on a graphite carbon electrode (GPC), the modified property of which was determined with handheld voltammetric systems. Following the determination of the analytical stripping conditions of 0.45 V amplitude, 30 Hz frequency, -1.4 V initial potential, and 4.0 mV increment potential, only a 60-s experimental accu...

The appeal of common property ideas may be traced in large measure to the fact that they seem to embody widely held values of equality. On the other hand, empirical examination of common property institutions reveals that they can coexist with significant inequality. In this paper, the relationship between common property and equality is examined. It is argued that the role of common property c...

A new five-point binary subdivision scheme with high continuity and convexity preservation is proposed in this paper. It is shown that the limit curves are C (k = 0, 1, . . . , 7) continuous for the certain range of the parameter. The range of the parameter for the property of convexity preservation of the limit curves is also provided. Experimental results demonstrate the efficiency and flexib...

The purpose of this case study was to describe the three-dimensional biomechanics of common ballet exercises in a ballet dancer with ischial tuberosity apophysitis. This was achieved by comparing kinematics between the symptomatic (i.e. ischial apophyseal symptoms) and contralateral lower limbs, as well as via reported pain. Results suggest consistent differences in movement patterns in this da...

0steoarthritis (OA) is a slowly-progressive degenerative joint disease characterized by a loss of joint cartilage and the subsequent exposure of subchondral bone (1). This eventually results in a self-perpetuating insidious disorder characterized by joint pain. New bone formation occurs in response to the chronic inflammation, and local tissue damage in an attempt to limit both movement and pai...
