Turkish researchers sought to determine the efficacy of acupressure application in pregnant women suffering from nausea, with or without associated vomiting, who were unable to receive conventional medication for these symptoms. Sampling consisted of pregnant women complaining of nausea with or without vomiting. The treatment group comprised 26 women; the control arm 25 and the placebo arm 24. The study occurred over a 9-day period. During this time, the treatment group applied acupressure bands to P6 acupressure point on days 4–6 of the study, with the placebo group receiving acupressure bands to a sham acupressure point, on the upper side of their wrists. Acupressure appeared to be effective in symptom control, and alleviation and placebo effects in reducing the symptoms of nausea and vomiting during pregnancy.
