The Editor-in-Chief and the Medical Editors at BioMed Central have retracted this article [1] because the first author did not fully declare his association with Koob Scolitech, which holds the rights in and to the Spinealite brace and has filed for a patent for that brace. Furthermore, the direct association between Koob Scolitech and the Spinealite brace was not made clear in the article. Thi...

We develop a symmetric analog of brace algebras and discuss the relation of such algebras to L∞-algebras. We give an alternate proof that the category of symmetric brace algebras is isomorphic to the category of pre-Lie algebras. As an application, symmetric braces are used to describe transfers of strongly homotopy structures. We then explain how these symmetric brace algebras may be used to e...

To study the design method of sectional area and initial tension of wire rope brace of the prestressed braced steel moment frame structure system, theoretical analysis of this structure system is conducted in this paper. The lateral stiffness formula is derived. It reveals the lateral stiffness is related to the lateral stiffness of bare steel moment frame, story height, the distance between co...

Methods It involved 59 adolescents, (50 girls, 9 boys), ages ranging between 10.0 and 17.0 years, all with Adolescent Idiopathic Scoliosis (AIS) with Cobb angle between 20-58 degrees. The adolescents were wearing the same kind of brace (Chêneau orthosis) for more than 6 months, for at least 16h per day. Three questionnaires were used: Trunk Appearance Perception Scale (TAPS), Bad Sobernheim Str...

OBJECTIVE Endogenous acetone production is a by-product of the fat metabolism process. Because of its small size, acetone appears in exhaled breath. Historically, endogenous acetone has been measured in exhaled breath to monitor ketosis in healthy and diabetic subjects. Recently, breath acetone concentration (BrAce) has been shown to correlate with the rate of fat loss in healthy individuals. I...

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...

BACKGROUND A hip brace, the WISH-type S-form brace, improved hip function scores markedly in patients with painful hip osteoarthritis (OA). To evaluate the biomechanical effects of the brace, gait analysis using a force plate was performed. METHODS For the gait of seven patients with this hip brace, characteristic parameters calculated from three-dimensional (i.e., vertical, forward, and medi...

BACKGROUND we investigated how ruptured Achilles tendons are loaded in a brace. There is an ongoing discussion whether patients should be recommended to bear weight on the injured limb. However, little is known about the effects of bracing on tensional loading of the healing Achilles tendon: it is uncertain if load-bearing actually stresses the Achilles tendon inside a brace. METHODS we measu...
