Physiological compliance and team performance.

Physiological compliance (PC) refers to the correlation between physiological measures of team members over time. The goals of this study were to examine ways of measuring PC in heart rate variability (HRV) data and the relationship between PC and team performance. Teams were tasked with entering both real and simulated rooms and "shooting" individuals with a weapon and identifying individuals without a weapon.

High dose ondansetron for reducing motion sickness in highly susceptible subjects.

Background: Ondansetron is currently being explored as a treatment for motion sickness due to its proven prophylactic effect on post-operative nausea, the nausea and vomiting associated with chemotherapy, and its lack of side effects. This study sought to compare the effectiveness of placebo, dimenhydrinate, and ondansetron for preventing motion sickness in highly susceptible subjects.

Methods: A total of 63 subjects with a history of frequent motion sickness and positive report of self-treatment of motion sickness with over-the-counter medications were divided into 3 groups of 20 (3 were disqualified).
