Background: One of the most important factors in the proper functioning of the military is the accurate assessment of feedback. Among these, the proper knee joint Proprioception is one of the most important factors in this regard. This study was performed to Evaluation of knee joint Proprioception Changes in military forces following a period of a static and dynamic stretching of hamstrings, qu...
Objectives Proprioception improvement in lower limb joints plays an important role in reducing falling risk in the elderly. Since proprioception improvement in the lower limb joints have the most relevance to better balance in the elderly, this study aimed to investigate the role of ankle and knee joint proprioception on balance improvement in the elderly after an aquatic exercise program. Met...
Background: Pigmented villonodular synovitis is a tumor that arises from the synovial membrane of the joint or tendon sheaths. Two main forms include a diffuse form that involves the whole synovial lining of a joint, bursa, or tendon sheath, and a less common localized form. The diffuse form typically involves the large joints, while the localized one typically occurs around the small joints of...
Beta-2 adrenoceptors in blood vessels are one of the active factors that play a role in regulation of tissue blood flow. in diabetic angiopathy, responsiveness of these receptors is decreased, while that is increased in inflammation. According to these opposite effects, the aim of this study was to investigate the vasodilatory response of knee joint blood vessels to salbutamol (Beta-2 adreno...
Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (PSO) algorithm. The ...
Drilling and blasting have numerous applications in the civil and mining engineering. Due to the two major components of rock masses, namely the intact rock matrix and the discontinuities, their behavior is a complicated process to be analyzed. The purpose of this work is to investigate the effects of the geomechanical and geometrical parameters of rock and discontinuities on the rock mass blas...
Background: The ultimate goal of the treatment of infectious knee arthritis is to protect the articular cartilage fromadverse effects of infection. Treatment, however, is not always hundred percent successful and has a 12% failurerate. Persistent infection is more likely to happen in elderly patients and those with underlying joint diseases,particularly osteoarthritis. Eradica...
Abstract Two cases (20 and 15 years old) of shoulder joint synovial chondromatosis were initially treated with arthroscopic debridement. One was further treated with a second arthroscopy and partial synovectomy (case 1) the second was fully treated by arthroscopic surgery (case 2). The postoperative control X- ray revealed no loose body and the joint was normal. One of the cases (case 1) was a...
this study evaluated the effects of end to end joint types of athel stripes at three level (end to end basic, end to end mitrated and end to end half lap joint) used in core layer veneered with three wood species (fir, beech and oak) and glued with three different ratio of melamine formaldehyde/urea formaldehyde resin (0:100, 25:75 and 50:50) on the bending strengths of bloakboard. according to...
Background and Objectives: The cause and pathophysiology of rheumatoid arthritis has not been fully understood and an experimental model of this disease is essential for research on the problem. In this research study, establishment and histopathological changes of chronic arthritis due to intra-articula...
