OBJECTIVE To provide a rationale for the examination of posture from a dynamic (behavioral) perspective and to relate the vertebral subluxation to postural instability and motion sickness via inefficiency. DATA COLLECTION A manual search of available reference texts and a computer search of literature from Index Medicus, PsycINFO, and ISI Science Citation Index Expanded were collected with an...

Scientists believe that low levels of a brain chemical called serotonin may make people susceptible to developing migraine headaches. Many people with migraine also have a problem with motion sickness, but it is not clear why this might be. We know that many drugs to treat motion sickness increase brain levels of serotonin, an important brain chemical. It is possible that low brain levels of se...

E-mail address: [email protected] The most cited theory on motion sickness is the conflict theory by Reason and Brand (1975) [1], stating that motion sickness occurs due to a conflict between the senses and stored patterns of motion. In addition, there seems to be evi...

BACKGROUND AND PURPOSE This case report describes physical therapy for motion sickness in a 34-year-old woman. The purpose of the report is twofold: (1) to provide an overview of the literature regarding motion sickness syndrome, causal factors, and rationale for treatment and (2) to describe the evaluation and treatment of a patient with motion sickness. CASE DESCRIPTION AND OUTCOMES The pat...

Motion sickness can be caused by a variety of motion environments (e.g., cars, boats, planes, tilting trains, funfair rides, space, virtual reality) and given a sufficiently provocative motion stimulus almost anyone with a functioning vestibular system can be made motion sick. Current hypotheses of the 'Why?' of motion sickness are still under investigation, the two most important being 'toxin ...

The brainstem is a structurally complex region, containing numerous ascending and descending fibres that converge on centres that regulate bodily functions essential to life. Afferent input from the cranial tissues and the special senses is processed, in part, in brainstem nuclei. In addition, brainstem centres modulate the flow of pain messages and other forms of sensory information to higher ...

This report refers to a body of investigations performed in support of experiments aboard the Space Shuttle, and designed to counteract the symptoms of Space Adapatation Syndrome, which resemble those of motion sickness on Earth. For these supporting studies we examined the autonomic manifestations of earth-based motion sickness. Heart rate, respiration rate, finger pulse volume and basal skin ...

The stress of motion sickness was experimentally provoked by Coriolis effect. Significant and reproducible increases from the basal serum level (delta mean +/- S.E.) of antidiuretic hormone delta - ADH: 48.2 +/- 4.6 pg/ml; p less than 0.0005), of growth hormone (delta - hGH: 10.0 +/- 1.2 ng/ml; p less than 0.0005), of prolactin (delta - hPRL: 186.5 +/- 29.9 muU/ml; p less than 0.0005), and of c...

BACKGROUND Motion sickness may crucially affect the operational performance of soldiers at sea and this differs between individuals and environments. OBJECTIVES To report on the prevalence and understand the risk factors for motion sickness among Singaporean sailors (seafarers) and attached army servicemen (non-seafarers) onboard naval platforms. METHODOLOGY Cross sectional study using self...
