BACKGROUND AND PURPOSE Pain sensitization may be one of the reasons for persistent pain after technically successful joint replacement. We analyzed how pain sensitization, as measured by quantitative sensory testing, relates preoperatively to joint function in patients with osteoarthritis (OA) scheduled for joint replacement. PATIENTS AND METHODS We included 50 patients with knee OA and 49 wi...

Rheumatoid arthritis (RA) is a chronic multisystem disease characterized by persistent joint inflammation associated with severe pain. Because RA is an immune-mediated joint disease and because type II collagen is considered an autoantigen, rodent models of arthritis using collagen type II-specific monoclonal antibodies are valuable for studying the pathogenesis of autoimmune arthritis and for ...

Dizziness and/or unsteadiness are common symptoms of chronic whiplash-associated disorders. This study aimed to report the characteristics of these symptoms and determine whether there was any relationship to cervical joint position error. Joint position error, the accuracy to return to the natural head posture following extension and rotation, was measured in 102 subjects with persistent whipl...

Acromioclavicular joint injuries represent nearly half of all athletic shoulder injuries, often resulting from a fall onto the tip of the shoulder with the arm in adduction. Stability of this joint depends on the integrity of the acromioclavicular ligaments and capsule as well as the coracoclavicular ligaments and the trapezius and deltoid muscles. Along with clinical examination for tenderness...

BACKGROUND Joint hypermobility syndrome describes a disorder in which musculoskeletal pain occurs in a generalized joint hypermobility substrate. The clinical picture comprises variable manifestations which involve mainly but not exclusively the musculoskeletal system, and evolve over the person's lifetime. CASE PRESENTATION Describing the case of a 20-year-old female with generalized arthro-...

Osteitis condensans of the sternoclavicular joint was first described by Brower et al in 1974. It is a rare benign disorder primarily affecting women of child-bearing age. Persistent pain and swelling in the medial part of the clavicle are the most common presenting symptoms and may represent an inflammatory process in the joint among other proposed etiologies. Radiological findings include scl...

Diagnosis and treatment of intra-articular hip problems in young patients present a challenge to hip surgeons. Previous studies have shown that non-invasive investigations such as radiography, computed tomography and magnetic resonance imaging provide limited help. Non-operative treatment is likely to result in persistent symptoms, and surgical options for intra-articular hip problems involve o...

For joint estimation of state variables and unknown parameters, adaptive observers usually assume some persistent excitation (PE) condition. In practice, the PE condition may not be satisfied, because underlying recursive problem is ill-posed. To remedy lack condition, inspired by ridge regression, this paper proposes a regularized observer with enhanced parameter adaptation gain. Like in typic...

objective: to determine the levels of polychlorinated biphenyls (pcbs) and polybrominateddiphenyl ethers (pbdes) as persistent organic pollutants (pops) in serum of primiparous women at the third trimester of pregnancy and identify the main determinants of pops levels such as socio-demographic, lifestyle, and diet in tehran. materials and methods: one- hundred eighty five serum samples from two...
