Introduction There are a wide variety of brace applications available today with different outcomes and different characteristics. The purpose of this study is to compare in-brace corrections of the series applied today to recent Chêneau series braces as presented in literature. methodology All patients were registered and fulfil the Scoliosis Research Society inclusion criteria for studies on ...

BACKGROUND In contemporary literature few have written in detail on the in-brace correction effects of braces used for the treatment of hyperkyphosis. Bradford et al. found their attempts effective, treating Scheuermann's kyphosis with Milwaukee braces, but their report did not specifically focus on in-brace corrections. White and Panjabi's research attempted to correct a curvature of > 50 degr...

Using Kelsey, Gellatly, and Clark (1958) unit load method, upper and lower bounds for the effective transverse shear moduli of a chevron folded core used in sandwich construction are analytically derived and compared to finite element computations. We found that these bounds are generally loose and that in some cases chevron folded cores are 40% stiffer than honeycomb-like cores.

Seismic excitation can cause significant energy to be released within structures. By using special devices, this consumed and dissipated without deforming structural members significantly. Due this, damage is minimized, casualties are prevented during earthquakes, structures extended in their useful life. Over the past five decades, it has been widely acknowledged that steel yielding dampers am...

The purpose of this study was to compare the results of the Chevron osteotomy to the DuVries' modification of the McBride procedure using identical criteria in two groups of patients. Thirty-two patients (48 feet) that had a Chevron osteotomy and 10 patients (17 feet) who had a modified McBride bunionectomy without metatarsal osteotomy for treatment of mild to moderate hallux valgus were retros...

Results Prior to participating the present study, the mean duration of brace treatment was 25.5 months for the Boston brace and 13.9 months for the Brace 2000. In the Boston brace group, the mean primary right thoracic curve was 35.8°, and the mean secondary curve measured 24.1°. The mean corrective force over the lumbar brace pad in standing position was 394 N, and over the thoracic brace pad ...

Materials and methods This is a retrospective study examining coronal plane spine radiographs of 27 adolescents diagnosed with idiopathic scoliosis and prescribed a Boston Brace-style thoracolumbosacral orthosis. Cobb angle, decompensation of C7, and Overall Balance Summation (OBS) (Carlson and Smith, 2007) were measured on pre-brace, in-brace, and immediately post-brace x-rays for each subject...

concentric bracing is one of the most common lateral load resistant systems in building frames, and areapplied to many structures due to their manufacturing simplicity and economics. an important deficiency in thebracing members is their irregular hysteretic loops under cyclic loading. in order to overcome this problem, it isadvised to restrain braces against buckling under compression, since b...

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...
