The predictive value of self-efficacy in the evolution of rheumatoid arthritis and its relationship with pain and function.

Background And Objectives: Rheumatoid arthritis (RA) primarily affects the upper limbs and can cause disturbances in the performance of daily activities. The main objective of this study was to establish the relationship between self-efficacy, pain intensity, and duration of symptoms in patients with RA and analyse how each influences functional disability, and to determine the predictive value of self-efficacy over the other variables.

Methods: Cross-sectional study with a sample of 117 women diagnosed with RA.

Assessment of the perception of vertical subjectivity in children born preterm.

Children born preterm have increased rates of paediatric mortality and morbidity. Prematurity has been associated with impaired visual perception and visuo-motor integration. The alteration of the perception of verticality translates into alterations of the vestibular system at central and/or peripheral level, which may manifest itself in symptoms such as imbalance, dizziness or even vertigo.

Test-retest of the Subjective Visual Vertical Test performed using a mobile application with the smartphone anchored to a turntable.

Purpose: The alterations of the Subjective visual vertical test are related to vestibular pathology. Our previously validated method to distinguish between healthy and pathological individuals measures the deviation from the Subjective visual vertical using a mobile application installed on a smartphone fixed to a turntable anchored to the wall. The aim of this study was evaluating the intra-observer reliability of our method in individuals with or without vestibular pathology.

Efficacy of the subjective visual vertical test performed using a mobile application to detect vestibular pathology.

Background: The subjective visual vertical (SVV) test is a sensitive test of vestibular dysfunction that allows the evaluation of otolithic organs; however, with the current method, there are technical and logistical limitations that make the application of this test difficult in the conventional clinic.

Objective: The objective of this study is to assess the effectiveness of detecting vestibular pathology using the SVV via a new screening method.

Methods: A consecutive sample of 62 patients with suspected vestibular pathology was included in the study.
