Practice of lingual orthodontics and practitioners’ opinion and experience with lingual braces in the United States
2020
Background A survey was done on practicing Orthodontists in the United States on their experience with lingual orthodontics. The objectives of this survey study were to assess 1) the satisfaction level with cases treated with lingual orthodontics, 2) factors that influence clinicians' decision to utilize or not utilize lingual braces in their current practices, and 3) intention of using lingual braces in their future practices, if not used currently, in the U.S. Material and methods A survey questionnaire was electronically distributed to 2,200 active U.S. members of the American Association of Orthodontists (AAO). Results 85 orthodontists completed the survey. About 25% of respondents prac…
Spinal Instability and the Issue of Bracing and Bed Rest.
2019
Nearly 20% of cancer patients develop symptomatic spine metastases. Metastatic spine tumors are most commonly extradural tumors that grow quickly and often cause persistent pain, weakness, paresthesias, urinary/bowel dysfunction, and/or paralysis. Surgical intervention aims to achieve more effective pain management, preserve/restore neurological function, provide local tumor control, and stabilize the spinal column. The desired result of treatment is ultimately to improve a patient's quality of life. Neurosurgeons employ multiple decision frameworks and grading scales to assess the need and effectiveness of a variety of surgical interventions ranging from minimally to maximally invasive. Li…
Clinical effectiveness and safety of a distraction-rotation knee brace for medial knee osteoarthritis
2015
Abstract Objective Evaluation of the clinical effectiveness and safety of a new custom-made valgus knee brace (OdrA) in medial knee osteoarthritis (OA) in terms of pain and secondary symptoms. Methods Open-label prospective study of patients with symptomatic medial knee OA with clinical evaluation at 6 and 52 weeks (W6, W52). We systematically assessed pain on a visual analog scale (VAS), Knee injury and Osteoarthritis Outcome Score (KOOS), spatio-temporal gait variables, use of nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesic-sparing effects of the brace and tolerance. Mean scores were compared at baseline, W6 and W52 and the effect size (ES) and 95% confidence intervals (95% CI…
Left Braces and the Yang-Baxter Equation
2021
L’equació quàntica de Yang-Baxter (YBE per les seues inicials en anglès) és una equació important en la física matemàtica introduïda per Yang en 1967. Un dels seus principals problemes oberts és trobar-ne totes les solucions. En 1992, Drinfeld va definir un subtipus de solucions, les conjuntistes, i va proposar el problema de trobar-les totes. Recentment, una subclasse de les solucions conjuntistes ha sigut molt estudiada: les involutives i no degenerades (a partir d’ara, les anomenarem simplement solucions). En 2007, Rump va introduir una nova estructura algebraica, les brides a esquerra, per a estudiar aquestes solucions, i va demostrar que cada brida a esquerra té una solució de la YBE a…
Effect of biomechanical footwear on upper and lower leg muscle activity in comparison with knee brace and normal walking
2021
Abstract Aim To evaluate the activity of knee stabilizing muscles while using custom-made biomechanical footwear (BF) and to compare it when walking barefoot and with a knee brace (Unloader®). Methods Seventeen healthy working-aged (mean age: 29 years; standard deviation: 8 years) individuals participated. The knee brace was worn on the right knee and BF in both legs. Surface electromyography (sEMG) data was recorded bilaterally from vastus medialis (VM), semitendinosus (ST), tibialis anterior (TA) and lateral gastrocnemius (LG) muscles during walking, and repeated-measures ANOVA with a post-hoc t-test was used to determine differences between the different walking modalities (barefoot, bra…
mHealth for the Monitoring of Brace Compliance and Wellbeing in Adolescents with Idiopathic Scoliosis: Study Protocol for a Feasibility Study
2021
Escoliosis idiopática del adolescente; Aplicación móvil; Eficacia del tratamiento Escoliosi idiopàtica de l'adolescent; Aplicació mòbil; Eficàcia del tractament Adolescent idiopathic scoliosis; Mobile application; Treatment effectiveness Attempts to optimize monitoring of brace adherence prescribed to adolescents with idiopathic scoliosis (IS) have generally relied on sensors. Sensors, however, are intrusive and do not allow the assessment of psychological and physical consequences of brace use that might underlie poor adherence. Mobile applications have emerged as alternatives to monitor brace compliance. However, the feasibility and utility of these app-based systems to assess key psychol…
Biomechanical effectiveness of a distraction-rotation knee brace in medial knee osteoarthritis: preliminary results.
2013
Abstract Background Non-pharmacological therapies are recommended for the care of knee osteoarthritis patients. Unloader knee braces provide an interesting functional approach, which aims to modulate mechanical stress on the symptomatic joint compartment. We aimed to confirm the biomechanical effects and evaluate functional benefits of a new knee brace that combines a valgus effect with knee and tibial external rotation during gait in medial osteoarthritis patients. Methods Twenty patients with unilateral symptomatic medial knee osteoarthritis were included and they performed two test sessions of 3D gait analysis with and without the brace at the initial evaluation (W0) and after 5weeks (W5…
Endocarditis due to Abiotrophia defectiva, a biofilm-related infection associated with the presence of fixed braces
2017
Abstract Rationale: Endocarditis with Abiotrophia defectiva represents 4.3% to 6% of all streptococcal endocarditis. The article presents diagnosis issues and the complexity of the treatment. Patient concerns: We present the case of a female white patient, aged 26 years, who developed infectious endocarditis caused by A defectiva, in the last trimester of pregnancy, a biofilm-related infection associated with the presence of fixed braces. Diagnoses: The diagnosis of infectious endocarditis was confirmed by the cardiac ultrasound examination that revealed a voluminous vegetation on the mitral valve, and acute mitral regurgitation caused by chordae tendinae rupture, and also by isolating Abio…
Left braces and the quantum Yang-Baxter equation
2019
[EN] Braces were introduced by Rump in 2007 as a useful tool in the study of the set-theoretic solutions of the Yang¿Baxter equation. In fact, several aspects of the theory of finite left braces and their applications in the context of the Yang¿Baxter equation have been extensively investigated recently. The main aim of this paper is to introduce and study two finite brace theoretical properties associated with nilpotency, and to analyse their impact on the finite solutions of the Yang¿Baxter equation.
Viridans streptococcal infective endocarditis associated with fixed orthodontic appliance managed surgically by mitral valve plasty
2018
Abstract Rationale: Streptococcus viridans, a heterogeneous group of alpha-hemolytic streptococci, is part of the normal flora of the mouth, usually responsible for dental caries (Streptococcus mutans, Streptococcus sanguinis), and pericoronitis, as well as for subacute infective endocarditis. They are responsible for 40-60% of the endocarditis cases occurring on the normal valves, especially in male patients and over 45 years of age. A change in the bacterial flora of the oral cavity is taking part after orthodontic fixed appliances are introduced into the oral cavity, change that is associated with an increased concentration of the acidogenic bacteria. Bacteraemia is the consequence of or…
