BACKGROUND Vascular access surveillance by ultrasound dilution blood flow rate (Qa) measurement is widely recommended; however, optimal criteria for detecting stenosis and predicting thrombosis in arteriovenous fistulae (AVFs) are still not clearly defined. METHODS In a blinded trial, we evaluated the accuracy of single Qa measurement, Qa adjusted for mean arterial pressure (Qa/MAP), and decr...

OBJECTIVE To describe the clinical and radiographic features of a group of juvenile idiopathic arthritis (JIA) patients who developed unilateral destructive wrist synovitis. METHODS All wrist radiographs performed yearly between 1986 and 2002 in JIA patients who had wrist involvement were retrospectively reviewed to identify patients who had unilateral erosive wrist synovitis, defined as a di...

Background—The relation between lesion length and effectiveness of brachytherapy is not well studied. Methods and Results—We compared serial (postintervention and follow-up) intravascular ultrasound findings in 66 patients with native coronary artery in-stent restenosis (ISR) who were treated with Ir (15 Gy delivered 2 mm away from the radiation source). Patients were enrolled in the Washington...

BACKGROUND Posttraumatic ulnar carpal translocation is a very rare condition that is caused either by fracture-dislocation injury or by purely ligamentous injury of the wrist. Its prognosis is poor and development of posttraumatic pancarpal wrist joint osteoarthritis is inevitable, and options for treatment are total wrist fusion or total wrist arthroplasty. METHODS A 24-year-old male sustain...

BACKGROUND Carpal tunnel syndrome (CTS) is a common work-related peripheral neuropathy. In addition to grip force and repetitive hand exertions, wrist posture (hyperextension and hyperflexion) may be a risk factor for CTS among workers. However, findings of studies evaluating the relationship between wrist posture and CTS are inconsistent. The purpose of this paper was to conduct a meta-analysi...

Abstract Background The use of smartphones has become widely popular, especially among young people, for multiple purposes other than communication, including gaming and internet browsing. hand wrist weakness is one the main complications associated with increased smartphones. This occurs due to repetitive flexion extension wrist, thumb, fingers, leading a significant musculoskeletal pathology....

OBJECTIVE This study compares the effect of wrist immobilization with non-immobilization on shoulder abduction, shoulder flexion, and shoulder rotation during feeding. METHOD Twenty right-hand-dominant participants with no upper-extremity dysfunction performed a controlled feeding activity under 2 separate wrist conditions: (1) while wearing a static wrist orthosis and (2) with the wrist not ...

In a reaching movement, the wrist joint is subject to inertial effects from proximal joint motion. However, precise control of the wrist is important for reaching accuracy. Studies of three-joint arm movements report that the wrist joint moves little during point-to-point reaches, but muscle activities and kinetics have not yet been described across a range of movement directions. We hypothesiz...

OBJECTIVE To assess the personal, physical and psychosocial factors associated with wrist or hand pain in Australian hospital-based nurses. METHODS Wrist or hand pain, associated disability and sickness absence, demographic, occupational, physical, psychosocial and personal factors among nurses working for three hospitals in Melbourne, Australia, were assessed in a cross-sectional study. Fact...
