Objective: This systematic review and meta-analysis investigates the effects optokinetic stimulation in people with vestibular disorders, with a specific focus on people with visually induced dizziness.

Data Sources: A systematic review was conducted using three electronic databases, CINAHL, PubMed and Physiotherapy Evidence Database (PEDro), from 2000 up to February 2024.

Review Methods: Randomised controlled trials were included, which compared: (a) adults above 18 years old with vestibular disorders, (b) the study evaluated interventions using optokinetic stimulation, (c) the intervention was compared with usual care; placebo or to no intervention, (d) the study included at least one outcome measure evaluating vestibular symptoms and (e) published in English.

Background: Anger is commonly experienced by family caregivers of people living with dementia yet its effect on caregivers' physical health remains unknown.

Objective: The primary aim of this study was to systematically review current evidence on the effects of anger and hostility on caregivers' physical health.

Methods: We searched Medline, EMBASE, PubMed, and PsycINFO up to January 2022.

Background: Although scoliosis is a 3-dimensional (3D) deformity, little research has been performed on the use of 3D imaging in brace curve correction. The purpose of the present study was to determine the effect of axial-plane parameters on the outcomes of bracing with a thoracolumbosacral orthosis for adolescent idiopathic scoliosis.

Methods: This prospective longitudinal cohort study included patients with adolescent idiopathic scoliosis who fulfilled the criteria for bracing according to the Scoliosis Research Society, and was conducted from the time the patient began wearing the brace through a minimum follow-up of 2 years or until a surgical procedure was performed.

Aims: The purpose of this study was to evaluate the incidence and analyze the trends of surgeon-reported complications following surgery for adolescent idiopathic scoliosis (AIS) over a 13-year period from the Scoliosis Research Society (SRS) Morbidity and Mortality database.

Methods: All patients with AIS between ten and 18 years of age, entered into the SRS Morbidity and Mortality database between 2004 and 2016, were analyzed. All perioperative complications were evaluated for correlations with associated factors.

Study Design: Retrospective study with prospective radiographic data collection.

Objective: To compare fusion level determination criteria using the fulcrum bending radiograph (FBR) and the last substantially touched vertebra (STV) as the lowest instrumented vertebra (LIV) in the radiographic outcomes of correction surgery for Lenke 1A and 2A scoliosis patients with a minimum of 2-year follow-up.

Summary Of Background Data: The STV has been proposed as the LIV in Lenke 1A and 2A curves to avoid postoperative distal adding-on.

Background: Existing scoring systems have suboptimal accuracy in prognosticating patients with spinal metastases. Currently, there is no superior method in predicting survival. This study aims to compare the accuracy of survival prediction by expert oncologists versus the revised Tokuhashi scores with actual survivals in a cohort of symptomatic spinal metastases patients.

Background: Bracing has been shown to decrease significantly the progression of high-risk curves to the threshold for surgery in patients with adolescent idiopathic scoliosis (AIS), but the treatment failure rate remains high. There is evidence to suggest that Schroth scoliosis-specific exercises can slow progression in mild scoliosis. The aim of this study was to evaluate the efficacy of Schroth exercises in AIS patients with high-risk curves during bracing.

Previous studies have highlighted the importance of lung-draining lymph nodes in the respiratory allergic immune response, whereas the lung parenchymal immune system has been largely neglected. We describe a new in vivo model of respiratory sensitization to Blomia tropicalis, the principal asthma allergen in the tropics, in which the immune response is focused on the lung parenchyma by transfer of Th2 cells from a novel TCR transgenic mouse, specific for the major B. tropicalis allergen Blo t 5, that targets the lung rather than the draining lymph nodes.
