Reports of posteffects following training sessions in Navy and Army flight simulators were obtained from pilots to determine the time course of recovery from simulator sickness. Results imply that posteffects may be a more serious problem than previously considered; 45% of all those queried (N greater than 700) reported having experienced symptoms of simulator sickness; 25% of the symptoms lasted more than 1 h after leaving the simulator; and 8% lasted more than 6 h. Postexposure symptoms were classified into three categories: visuomotor (based on disturbances in oculomotor control; e.g., eyestrain), disorientation (based on disturbance in postural control; e.g., dizziness), and nausea (vagal/autonomic symptoms). A safety risk may be posed particularly by the moderately high frequency of symptoms involving postural disequilibrium. Guidelines for coping with risks are discussed.

Virtual reality is a promising tool for improving efficacy of exposure therapy for childhood anxiety disorders (CADs), particularly for exposures that are challenging to orchestrate in vivo. The present study compared virtual reality exposure (VRE) to verbal imaginal exposure (IE) on anxiety elicited, homework completion, and preparation for subsequent exposures. Forty-five youth with CADs completed both types of exposure in session (order randomly assigned), practiced one form of exposure as homework (randomly assigned), and returned a week later to repeat both exposures (in randomized order), provide user feedback, and complete a related in vivo exposure.

To simplify the Chinese version of the Visually Induced Motion Sickness Susceptibility Questionnaire (VIMSSQ), develop the simplified Chinese version of VIMSSQ, and evaluate its performance. A cross-sectional study was conducted between May and July 2023. The Chinese version of the VIMSSQ was distributed to 783 university students at North China University of Science and Technology.

Mobility is essential for individuals with physical disabilities, and wheelchairs significantly enhance their quality of life. Recent advancements focus on developing sophisticated control systems for effective and efficient interaction. This study evaluates the usability and performance of three wheelchair control modes manual, automatic, and voice controlled using a virtual reality (VR) simulation tool.

Introduction: In space, under weightlessness conditions, human brain activity is changed due to the shifting of body fluid and blood toward the cephalic region. This shifting leads to changes in cerebral hemodynamics and, consequently, neurophysiological function, which impacts mental functions like cognition and decision-making capabilities of space travelers. The present study reports the effect of acute exposure to simulated microgravity on cognitive functions and event-related potentials.

Introduction: Vestibular migraine (VM), particularly its chronic variant, poses a diagnostic challenge. Patients suffering from VM may not have the characteristic headaches associated with the dizziness. In these cases, a marker for migraine pathology in general could help appropriately diagnose certain types of dizziness as migrainous despite these patients not meeting current diagnostic criteria for VM.
