Dependence of motion sickness in automobiles on the direction of linear acceleration.

1982

Thirty-eight normal volunteers were tested in an ambulance car while being accelerated in one of the following positions: (1) sitting upright facing forward in the car, (2) lying supine on a stretcher head forward, (3) supine position head backward. Consecutive short periods of negative horizontal acceleration (0.7–0.95 g) were achieved by brisk braking manoeuvres of the car, followed by weak reacceleration (0.15 g). Motion sickness symptoms were observed and recorded after each experiment using a special motion sickness scaling index which was weighted according to the strength of any particular symptom. The results indicate that horizontal linear acceleration in a car, such as experienced…

Ten-year follow-up of health-related quality of life among ambulatory persons with multiple sclerosis at baseline

2016

Purpose The aim of this 10-year follow-up study was to determine changes in health-related quality of life (HRQoL) over time among ambulatory persons with MS (PwMS) at the baseline using generic and disease-specific instruments. Methods Of 109 independently walking PwMS included in a population-based study in 2002, 77 (70.6 %) were re-assessed in 2012. HRQoL was captured using the 36-Item Short Form Survey Instrument (RAND-36), 15D instrument (15D), and the Multiple Sclerosis Quality of Life-54 (MSQOL-54). Repeated-measures ANOVA and effect size (ES) calculations (Cohen’s d) were used in the statistical analysis. Results The RAND-36 physical health composite score (p = 0.003, ES = 0.26) and…

Assessing Somatic, Psychosocial, and Spiritual Distress of Patients with Advanced Cancer

2012

Objective: For adequate distress assessment in palliative care, we developed a screening evaluation tool. Methods: Proven methods of scale construction led to a 53-item pilot form of the Advanced Cancer Patients’ Distress Scale (ACPDS). We used Hornheide Questionnaire (HQ), Palliative Outcome Scale (POS), and Minimal Documentation System (MIDOS) for validation. Advanced cancer patients (N = 168) from 3 centers for palliative medicine (aged 23-89, 51% female) filled out the questionnaire. Results: With a principal component analysis (PCA), we extracted 5 distress scales (emotional reactions/physical restrictions, communication deficits, negative social reactions, pain, and gastrointestinal s…

Quality of Life in Individuals Affected by Arnold Chiari Malformation: Comparison and Validation of a Measurement Instrument.

2017

BACKGROUND Introduction. Arnold Chiari Malformation (ACM) type I is a pathology whose symptomatology has repercussions for the quality of life of those affected by it. Quality-of-life measurement instruments can allow the severity of the impact of Chiari type I malformation on patients' lives to be monitored. The Chiari Symptom Profile (CSP) is a valid and reliable instrument designed for this purpose. The aim of the study was to adapt the CSP to Spanish and to explore the reliability and validity of this construct in the context of Spanish-speaking patients with ACM. METHODS The English CSP instrument has a good internal validity and consistency. We used a standardized procedure for the li…

Clinical verification of a unilateral otolith test.

1992

Abstract In a previous study13 we reported promising results for a new test to differentiate in vivo unilateral otolith functions. That study pointed to a need for further validation on known pathological cases. In this presentation we will detail the results gathered on a group of clinically verified vestibular defectives (verum) and a normal (control) group. The subjects in the verum group were former patients of the ENT clinic of the university hospital. These subjects had usually suffered from neurinoma of the VIIth cranial nerve or inner ear infections. All had required surgical intervention including removal of the vestibular system. The patients were contacted usually two or more yea…

Health-Related Quality of Life and Somatization in Patients With Long-Term Low Back Pain

2001

Study Design. For this study, a prospective cohort of 109 patients was recruited consecutively at an orthopedic inpatient unit of a university hospital. Three self-report instruments were administered to patients with sciatica believed to be caused by a herniated lumbar disc to examine their quality of life and psychic stress at baseline and at the 1-year follow-up visit. Objectives. To investigate whether patients who have undergone a previous discectomy experience greater psychic stress than patients with no surgery, and to determine whether the groups differed regarding their health-related quality of life at the follow-up visit. Summary of Background Data. Previous studies have describe…

Metoclopramide and diphenhydramine in the treatment of hyperemesis gravidarum: effectiveness and predictors of rehospitalisation.

2007

Abstract Objectives Hyperemesis gravidarum (HG) is the second most common reason for hospitalisation during pregnancy. Since 2002, a new HG treatment protocol consisting of metoclopramide plus diphenhydramine was put in place at CHU Sainte-Justine, affiliated to University of Montreal, Quebec, Canada. The objectives of this study were to evaluate the effectiveness of this new HG protocol regarding length of hospitalisation for HG, rate of rehospitalisation, evolution of nausea and vomiting symptoms, and rate of adverse events. Study design A retrospective cohort study was conducted from 2002 to 2006 on the population of pregnant women diagnosed with HG, and treated at CHU Sainte-Justine wit…

Genre-dependent effects of 3D film on presence, motion sickness, and protagonist perception

2016

Do the increasingly popular 3D movies change how we perceive the content of the movie? We presented short (3.21 min) film sequences to observers equipped with shutter glasses. Three genres (horror, action, and documentary) were crossed with three between-subjects viewing conditions (director’s 3D, artificial 3D, and 2D). Observers had to rate how the film impressed them in terms of arousal, motion sickness, presence, and immersion. They also judged the personality, attractiveness, and intelligence of the protagonist in all viewing conditions. Not surprisingly, horror films produced more arousal and presence than action films. Documentaries scored lowest on presence. Action movies produced t…

A Case Study on Vestibular Sensations in Driving Simulators.

2022

Motion platforms have been used in simulators of all types for several decades. Since it is impossible to reproduce the accelerations of a vehicle without limitations through a physically limited system (platform), it is common to use washout filters and motion cueing algorithms (MCA) to select which accelerations are reproduced and which are not. Despite the time that has passed since their development, most of these algorithms still use the classical washout algorithm. In the use of these MCAs, there is always information that is lost and, if that information is important for the purpose of the simulator (the training simulators), the result obtained by the users of that simulator will no…
