In this cross-over study, we evaluated two types of knee brace commonly used in the conservative treatment of osteoarthritis of the medial compartment. Twelve patients confirmed radiologically as having unilateral osteoarthritis of the medial compartment (Larsen grade 2 to grade 4) were studied. Treatment with a simple hinged brace was compared with that using a valgus corrective brace. Knee ki...

The purpose of this investigation was to determine the differences in joint moment and power patterns during walking with and without a functional knee brace and when the brace was deliberately misaligned with the knee axis of rotation. Five participants were asked to walk over a force platform with and without the brace as well as during a condition where the axis of rotation of the brace had ...

Aim To evaluate the effectiveness of nighttime bracing in AIS. Methods: Inclusion criteria were patients diagnosed with AIS and skeletal immature. With an apex of the primary curve from TH7 and below and with a Cobb angel between 2045 degrees. The patients were asked to wear the brace at least 7-8 hours pr. night. No other previous treatments were accepted and a follow up at least 6 months out ...

Background High correction bracing is the most effective conservative treatment for patients with scoliosis during growth. Still today braces for the treatment of scoliosis are made by casting patients while computer aided design (CAD) and computer aided manufacturing (CAM) is available with all possibilities to standardize pattern specific brace treatment and improve wearing comfort. Objecti...

The supporting formwork system as one of the most commonly used temporary structures in process building construction, its safety accidents frequently occur. wheel-buckled steel pipe is a new type developed under this background, and scissor brace kind component system, have played an important role improving bearing capacity system. This paper uses ABAQUS finite element analysis software to es...

Background Little is known about the in-brace correction effects of braces used for the treatment of kyphosis. While Bradford et al. have found their attempts effective, treating Scheuermann's kyphosis with Milwaukee braces, they did not report on in-brace corrections. According to White and Panjabi, it seems the appropriate approach is to try to correct a curvature of > 50° with the help of di...

BACKGROUND The aim of the study was to retrospectively investigate the changes in pulmonary function and its influencing factors in patients with adolescent idiopathic scoliosis (AIS) undergoing preoperative brace treatment or not. METHODS Total 237 AIS patients (43 boys, 194 girls) who underwent operations and had a complete record of pulmonary function tests were enrolled and were divided i...

Compared with traditional buckling-restrained brace (BRB), the steel-angle-assembled (SAA-BRB) is an innovative BRB light-weight, accurate control of geometrical dimensions, easy installation, and convenient disassembly. The SAA-BRB comprises external restraining system a cruciform-sectional inner core. Four steel angles assemble connection high-strength bolts, spacers are installed between cor...

Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...
