periodic evaluation and monitoring the health and economic outcome of joint replacement surgery is a common and popular process under the territory of joint registries in many countries. in this article we introduce the methodology used for the foundation of the national iranian joint registry (ijr) with a joint collaboration of the social security organization (sso) and academic research depar...

the kinematics and dynamics of two industrial cooperating robots are presented in this paper. the noc (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. the joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. to this end, minimizing the cr...

in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...

background : joint proprioception plays an important role in limb movement and awareness of position sense. diabetes has a lot of complications such as lossof sensoryfunction, which canleadtoimpaired balance, thus the aim of this study to evaluated joint proprioception and balance in diabetic patients. methods: twenty type ii diabetic patients and20healthy controls participated in this case-con...

background: benign joint hypermobility syndrome (bjhs) is a disorder due to laxity of supporting connective tissue of joints. inguinal hernia is also proposed due to weak supporting tissue that may be a clinical presentation of a more widespread problem of connective tissue. materials and methods: in a cross-sectional study, prevalence of benign hypermobility joint syndrome (bhjs) was assessed ...

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...

primary musculoskeletal lymphoma presenting as monoarthritis is very rare. less than 20 cases have been reported. the ultrasound appearances have not been reported to date. we present a young female of primary knee lymphoma with synovial involvement presenting as monoarthritis. the ultrasound and mri features are discussed.

conclusions roll stitch technique had superior outcome compared to the modified kessler technique, when performed in the mcpj area. level of evidence: therapeutic (level iii) background proper suturing technique is needed to ensure good outcome in extensor tendon surgery. different techniques have been reported for the repair of extensor tendon injuries at the level of the metacarpophalangeal j...

a fundamental assumption in prosthetic dentistry is that the axis-orbital plane will usually be parallel to the horizontal reference plane. most articulator systems have incorporated this concept into their designs and use orbitale as the anterior reference point for transferring the vertical position of the maxilla to the articulator. clinical observations of cantonese patients suggest that in...
