T he effectiveness of brace treatment for scoliosis was controversial until recently. Brace treatment had not been proven to prevent progression of the scoliotic curve. 1 There had been no standardized study of this issue, and there were no significant differences among the types of braces used. 1 The unwillingness of children to wear braces raised concern, especially among physicians, about wh...

Custom-made and off-the-shelf functional knee orthoses from four manufacturers were evaluated. Anterior tibial translation testing was performed using a pneumatic mechanical surrogated knee. The mechanical surrogate was interfaced with a servohydraulic materials testing system, which applied all anterior/posterior displacements to an ultimate anterior load of 400 N. Comparison of the individual...

We examine links between the theory of braces and set-theoretical solutions Yang–Baxter equation, fundamental concepts from quantum integrable systems. More precisely, we make connections with Hecke algebras identify new groups associated to set-theoretic coming braces. also construct a novel class discrete systems derive symmetries for corresponding periodic transfer matrices.

This paper presents a performance-based placement design method for the control of the earthquake responses of a multistory building using tuned electromagnetic inertial mass dampers (T-EIMDs). The T-EIMD consists of a ball screw mechanism, a gear, a flywheel, and an electric generator installed in a cylinder, and a spring element connected in series. The ball screw mechanism converts the axial...

During human movement, the leg can be represented as a mechanical spring, with its stiffness potentially contributing to sports performance and injury prevention. Although many individuals perform athletic activities with joint stabilizers, little is known about the effects of prophylactic lower extremity braces on leg stiffness. The objective of this study was to investigate the effect of ankl...

Decreases in patellofemoral pain have been demonstrated with bracing; however, the mechanisms of pain reduction remain unclear. Our purpose was to evaluate the hypothesis that patellofemoral bracing decreases peak pressure on the retropatellar surface through an increase in patellofemoral contact area. Nine cadaveric knees were tested during simulated free-speed walking with no brace, a knee sl...

AIM This study was designed to adapt the original English-language COAS (Children's Orthodontic Attitude Survey) for third- grade schoolchildren to the Italian cultural environment and to investigate its properties in typical populations, as well as to evaluate children self-perception of their dental appearance. STUDY DESIGN The COAS questionnaire for third-grade schoolchildren was translate...

Purpose To determine if metal artifact reduction can minimize magnetic susceptibility artifacts in the orbits for an eye plaque brachytherapy patient with metallic dental braces. Material and methods A 62-year-old female patient with a choroidal melanoma in the right eye received a 1.5 T magnetic resonance imaging (MRI) simulation for 3D eye plaque brachytherapy planning. The protocol include...

Arthritic knee braces are pa...

We characterize the director structures in electroconvection patterns of nematic liquid crystals by means of polarising microscopy. This study was stimulated by a theory put forward by Rossberg et al. [1] who propose a mechanism for chevron texture formation. We characterize the relation between the wave vector modulation and in-plane twist modulations of the director field. In addition to the ...
