We used an instrumented wheelchair ergometer and 3D motion analysis system to collect joint kinematic and temporal data, as well as hand rim and joint kinetics, in 47 manual wheelchair users (MWCUs) (15 with upper-limb impairment and 32 without upper-limb impairment). The group with upper-limb impairment propelled with a higher stroke frequency and reduced hand-rim contact time, and smaller pea...

Objective: To evaluate the effect of the sequential treatment of temporomandibular joint ankylosis with secondary deformities by distraction osteogenesis Methods: We retrospected 40 patients with temporomandibular joint ankylosis, whose age varied from 9 to 53 years old (average 24.5 years old), in department of Oral and Maxillofacial Surgery, Stomatological Hospital, the Fourth Military Medica...

INTRODUCTION The distal radioulnar joint is of paramount importance for the proper function of the upper extremity. There is a wide variety of procedures for the treatment of its advanced pathology but none of them is capable of providing a stable load-bearing joint. CLINICAL CASE We present the case of a 54 year old man who was treated by a semiconstrained bipolar distal radioulnar joint art...

Lumbar zygapophyseal joints have long been considered a source of low back pain with or without leg pain. The objective of this prospective study was to investigate the therapeutic effectiveness of lumbar zygapophyseal joint radiofrequency denervation (RFD) followed by physical therapy, for the treatment of refractory lumbar zygapophyseal joint mediated low back pain secondary to lumbar zygapop...

PURPOSE The aim of this study was to investigate prophylactic treatment effects in Korean patients with severe hemophilia A. METHODS A prospective study of 32 severe hemophilia A patients was conducted with the approval of the Institutional Review Board at the Eulji University Hospital. Two patients received primary prophylaxis; whereas, the other 30 patients were divided into 2 groups-second...

Examination of a painful hip is fairly concise and reliable at detecting the presence of a hip joint problem. Hip joint disorders often go undetected, leading to the development of secondary disorders. Using a thoughtful approach and methodical examination techniques, most hip joint problems can be detected and a proper treatment strategy can then be implemented based on an accurate diagnosis. ...

Primary synovial chondromatosis is a rare condition of idiopathic synovial chondrometaplasia and usually occurs during the third to fifth decades of life. Conversely, secondary synovial chondromatosis results from the growth of separated particles from articular cartilage or osteophytes in patients with joint diseases, such as degenerative osteoarthritis, and occurs mostly in elderly people. We...

The principles of physical rehabilitation therapy can be applied to the horse to provide a reduction in discomfort and dysfunction associated with the various forms of joint disease. Physical agents,such as ice, heat, electricity, sound, light, magnetic fields, compression, and movement, can be used by the rehabilitation therapist to attempt to control pain, reduce swelling, and restore optimal...

The present work summarises a numerical procedure aimed to the residual strength assessment of a cracked butt joint, based on R-curve analysis and plastic collapse prediction. In a linear elastic fracture analysis, the SIF’s (Stress Intensity Factors) evaluation is based on the use of the Dual Boundary Element Method, as implemented in the BEASY code. A two -dimensional approximation (plane str...

Osteoarthritis or degenerative joint disease is a condition characterised by degeneration of articular cartilage often associated with the formation of new bone at joint surfaces on margins. Commonly encountered in dogs, osteoarthritis may have a gradual onset, but may also occur acutely. Osteoarthritis can be a primary disease of joint cartilage, but is more after secondary to abnormal stresse...
