BACKGROUND The role of knee bracing in anterior cruciate ligament reconstructions is controversial. HYPOTHESIS Functional bracing will have an effect on subsequent knee injury in skiers with anterior cruciate ligament reconstruction. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS From 1991 to 1997, 11606 skiers at a major destination ski resort underwent preseason knee screening...

AIM Rehabilitation of adolescent idiopathic scoliosis (AIS) requires a careful choice from among the possible treatments, such as bracing and exercises, according to the patient's needs. According to the literature, there is little evidence regarding the efficacy of these rehabilitation instruments. During the past few years, a full series of studies has been carried out to investigate their ef...

optimization of structures for minimum weight has become important in the recent designs. in this study, a genetic optimization algorithm for weight minimization of steel frames has been used. the genetic algorithm is an optimization and search technique based on the principles of genetics and natural selection. constraints regarding material strength and serviceability are taken from “aisc cod...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction is associated with a high incidence of second tears (graft tears and contralateral ACL tears). These secondary tears have been attributed to asymmetrical lower extremity mechanics. Knee bracing is one potential intervention that can be used during rehabilitation that has the potential to normalize lower extremity asymmetry; however, lit...

Introduction The review evaluates the up-to-date evidence for the treatment of spinal deformities, including scoliosis and hyperkyphosis in adolescents and adults. Material and Methods The PubMed database was searched for review articles, prospective controlled trials and randomized controlled trials related to the treatment of spinal deformities. Articles on syndromic scoliosis were excluded...

Objective: The current study is aimed at evaluating the effect of active muscle on the dynamics of the pre-impact bracing car occupant using numerical simulations. The objective of the study includes identifying the sensitivity of occupant injury metrics to the level of pre-impact bracing action. Problem Outline: Bracing or pre-impact muscle tensing, one of the key reflexive actions adopted fre...

BACKGROUND Traditionally, odontoid fractures have been treated with different bracing techniques resulting in variable degrees of successful healing. Surgical intervention is becoming more widely practiced as a primary intervention. The purpose of this report was to survey our recent experience in southern Alberta to determine potential outcome differences in management strategies. METHODS We...
