The article aims to find the buckling loads for pinned?rotationally restrained shallow circular arches in terms of rotational end stiffness, geometry and material distribution. loading is a concentrated vertical force placed at crown. A geometrically nonlinear model presented which relates not only axial but also bending moment membrane strain. load-strain relationship established between strai...

OBJECTIVES/HYPOTHESIS The majority of laryngectomy patients fail to use a hands-free valve on a daily basis, mainly due to fixation problems of the adhesive baseplate housing. To support adhesive housings during hands-free speech a new external neck brace (ENB 2.0) was developed. The effect of the brace was assessed in terms of a qualitative assessment, adhesive lifetime, maximum phonation time...

Background: A thoracic curve degree of greater than 45° leads to thoracic hyperkyphosis, and its common treatment method is orthotic treatment. The acceptance rate of spinal orthosis depends on in-brace correction, patient`s compliance and quality of life. Objective: In this study, we aimed to compare in-brace correction, compliance and quality of life in patients with thoracic hyperkyphosis ...

Results For the 22 symmetric CAD TLSOs, initial in brace correction of thoracic curves was 9.1 degrees, with average out of brace thoracic curve 25.2 degrees, and lumbar curve correction of 10.3 degrees, with average out of brace lumbar curve 27.8 degrees. The percentage of correction in CAD versions was 36.1% thoracic, and 37.1% lumbar. For the 12 asymmetric, TLSOs molded supine with manipulat...

STUDY DESIGN Retrospective controlled cohort study comparing the in-brace correction of two samples of scoliosis patients with braces of different computer aided design (CAD). PURPOSE In-brace correction and compliance correlate with outcome. The more standardized CAD braces that are available should enable improved in-brace correction and outcome. This study compared recent CAD brace develop...

The previously formulated model of the gravity-driven collapse of the twin towers of the World Trade Center on 9/11/2001 was shown to match all the existing observations, including the video record of the crush-down motion of the top part of tower during the first few seconds, the seismically recorded duration of collapse, the size distribution of particles caused by impact comminution of concr...

BACKGROUND The CMCR brace (Corset MonocoqueCarbone respectant la Respiration -which means Monoshell Carbon Brace respecting Breathing) is an innovative brace, used in orthopaedic treatment for progressive thoracic, thoraco-lumbar or combined scoliosis, whatever their etiology. It can be used at the very young age without disrupting the chest growth, but should be kept for reducible scoliosis in...

Bad Sobernheim Stress Questionnaire (BSSQ)-Deformity and BSSQ-Brace are the most widely used instruments for evaluating stress levels in adolescent idiopathic scoliosis (AIS) patients under brace treatment, and good reliability and validity have been demonstrated across different cultures. Great stress has been found among many adolescents, becoming a major concern for professionals. However, n...

Methods A total of 76 consecutive adolescent idiopathic scoliosis patients who were treated with brace included in this study. 20 of 45 patients who were treated with SpineCor brace, and 13 of 31 patients who were treated with rigid brace, were able to finish pulmonary function test (PFT). PFT is administered to 33 patients before and immediately after wearing the brace. TLC, RV, RV/TLC, FVC, F...
