Active clinical trials for "Motion Sickness"

A multi-center, randomized, double-blind, placebo-controlled study to evaluate the efficacy of tradipitant in the treatment of motion sickness.

This multi-site Phase 3 clinical trial is a randomized, double-blind, placebo-controlled study to identify the safety and efficacy of DPI 386 nasal gel (intranasal scopolamine gel) for the prevention and treatment of nausea associated with motion sickness. The study will be conducted aboard military ships undergoing military operations or aboard commercial boats rented for the study to obtain data in a real world environment. The study will have three arms: DPI-386 nasal gel, placebo nasal gel, and Transderm Scop® (1.0 mg/72 hours; transdermal scopolamine patch [TDS], the current standard of care for the treatment of motion sickness). The study will include 120 subjects per arm, for a total of 360 subjects (n=360). A double-dummy design will be used to mask the treatment assignment. All subjects will receive both a patch and nasal gel: DPI-386 Nasal Gel + placebo patch, placebo nasal gel + placebo patch, or TDS patch + placebo nasal gel.

Participants were selected from the military navy crewmembers prior to commencing of active sailing. A vestibular time constant was calculated based on velocity step testing on a rotatory chair at baseline, 3 months and 6 month following active sailing duty. A seasickness questionnaire (WIKER) was completed during follow-up visits. study participants were divided to three groups based on WIKER score - susceptible , non-susceptible and habituating. Vestibular time constant was compared between study groups.

This a case control study on seasickness susceptibility. 86 healthy maritime personal were divided to seasickness susceptible and non susceptible groups based on a seasickness questionnaire (Golding) and motion sickness score. All subjects from both groups underwent video head impulse testing (vHIT). VHIT parameters - gain, asymmetry ect were compared between both groups.

Sea sickness represents a major limitation on the performance of ships' crew. One of the challenges faced by the physician in the motion sickness clinic when prescribing anti-sea sickness medication is to select the appropriate drug for the patient. Difficulties arise due to high variability in the response to different drugs. In the case of sea sickness, the current procedure is to examine the drug's efficacy in each individual during real time exposure to sea conditions. A number of studies have documented the presence of sea sickness drug receptors in the vestibular nuclei, which determine the vestibular time constant. Two clinical vestibular tests which evaluate the time constant are the Velocity Step and OKAN tests. The purpose of the proposed study is to evaluate the influence of motion sickness drugs on the vestibular time constant, as a possible bioequivalent of drug potency in the individual subject. Eighty crew members will be recruited and divided into groups responsive and non-responsive to the sea sickness drugs scopolamine and meclizine. Subjects having a Wiker score of 7 in waves 1 meter high without drug treatment, and no improvement in symptoms after treatment will be defined as non-responsive to sea sickness drugs. Subjects having a Wiker score of 7 in waves 1 meter high without drug treatment, and a Wiker score of 4 or less after treatment, will be defined as responsive to drug therapy. Kwells, Bonine and placebo, will be assigned to each subject in a random, double-blind fashion. Each group will perform the Velocity Step and OKAN tests before, one and two hours after drug or placebo administration.

Sea sickness syndrome is present for 80% of persons on board when the boat rotation missions Astrolabe, sometimes there is a risk of very significant dehydration. A special unit specialized in the fundamental study of the vestibular system (inner ear), sensory organ at the base of visual-vestibular conflict inducing this syndrome, also provides medical support for parabolic flights (flight reproducing weightlessness) where this syndrome is strongly present. The goal of the study is to assess the frequency of occurrence of this sea sickness syndrome on the Astrolabe, to understand the triggers (type of boat movements, personality traits, anxiety / stress) without changing habits on board for those on board taking a antinaupathique treatment given by the ship's doctor. This study will be done in collaboration between INSERM U 1075 (France) and the Laboratory of military research VIPER specialized in extreme environments (Belgium). The ultimate goal will be to provide the best recommendations and the best treatment regimen to alleviate as best as possible the symptoms of people on board of the Astrolabe so scientists on board can perform their work.

Current virtual reality device makes motion sickness and visual fatigue having limitation for recreation and other clinical approaches. Still there is no standardized quantification of motion sickness and visual fatigue measurement with objective approach. Current biofeedback accompanied with virtual reality would be promising tool for stress relief.
