A double-blind placebo controlled evaluation of acupressure in the treatment of motion sickness.
We used 36 subjects in a double-blind placebo controlled experiment to evaluate the effectiveness of acupressure as a prophylaxis against motion sickness. There were two independent variables with two levels each: acupressure vs. placebo, and motion sickness high vs. low susceptible subjects. The provocative stimulus was rotation about two orthogonal axes. Signs and symptoms of motion sickness were scored both by the subject and the observer. In spite of previous reports to the contrary, acupressure provided no protection against motion sickness for either high or low susceptible subjects.
