Chronic motion sensitivity refers to a sensation of unwellness caused by physical or discerned motion and has a prevalence of 28% in the general population and it is more common in women (27.3%) compared to men.
The investigators theorize that individuals with chronic motion sensitivity will have an impaired inner ear reflex and will be less physically active. Hence, the purpose of this study is to;
Chronic motion sensitivity (CMS), also known as motion sickness, refers to a sensation of unwellness caused by physical or discerned motion. CMS has a prevalence of 28% in the general population and it is more common in women (27.3%) compared to men.
Based on established evidence that individuals with chronic motion sensitivity demonstrate impaired postural stability with vestibular system impairment adjudged to be an inciting stimulus for chronic motion sensitivity, and individuals who practiced more physical and sporting activities have less motion sickness susceptibility than individuals who did not, the investigators theorize that individuals with chronic motion sensitivity will have an impaired inner ear reflex, causing them to be more reliant on other sensory systems like their muscles and joints, and their vision, we also theorize that individuals who are physically active will be less susceptible to chronic motion sensitivity.
The purpose of this study is to;
Participants between the age of 20 and 40 with and without a self-reported history of chronic motion sensitivity (i.e, experiencing nauseousness and/or dizziness during while using various means of transportation such as, car, train, bus, boat, and airplane and/or, recreational fun-fair rides and/or when exposed to conflicting visual images). Participants will be excluded if they report a medical diagnosis of central nervous system disorder, impaired cervical spine range of motion, migraines, seizure disorder, vestibular dysfunction, or any musculoskeletal dysfunction that can limit their participation in the study.

Participants will be recruited from Loma Linda University and surrounding communities. The study will be conducted in the Loma Linda University Physical Therapy Department's Neuroscience Research Laboratory. Participants between the age of 20 and 30 with and without a self-reported history of chronic motion sensitivity (i.e, experiencing nauseousness and/or dizziness during while using various means of transportation such as, car, train, bus, boat, and airplane and/or, recreational fun-fair rides and/or when exposed to conflicting visual images)

Exclusion Criteria:
Participants with a self-reported history of chronic motion sensitivity and who scored greater than or equal to the 30th percentile on the Motion sickness susceptibility questionnaire short form.
Participants without a self-reported history of chronic motion sensitivity and who scored less than or equal to the 25th percentile on the Motion sickness susceptibility questionnaire short form.
Bertec vision advantage
Scores on 4 parametters- Baseline visual acuity (Logarithm of the minimum angle of resolution LogMAR)- A measure of optotype size with lower values signifying smaller optotype size and better vision with the head static, Visual processing time (Mili seconds) this is the time taken to identify the size of the optotype, Dynamic visual acuity (Logarithm of the minimum angle of resolution LogMAR)-A measure of optotype size with lower values signifying smaller optotype size and better vision with the head dynamic, Gaze stability test (Degrees per second), this is the highest speed at which the participant can identify the optotype while the head is moving.
Time frame: 1 day
Computerized dynamic posturography with immersion virtual reality
Average scores under 2 conditions- Condition one- Eye open, Stable platform, Condition 2 Eye open, sway referenced platform. Each condition measured gives a score known as the equillibrum score measured as age matched normative data with higher scores signifying stronger balance , and a lower scores signifying weaker balance
Time frame: 1 day
International Physical activity questionaire short form
Questionaire to assess physical activity
Time frame: 1 day
Motion sickness susceptibility questionnaire short form
Questionnaire used to asses motion sickness susceptibility
Time frame: 1 day
Plan to share: Undecided
