This study examined the effect of sensory affect stimulation (SAS) delivered through the volar surface of the wrist on pregnancy-induced nausea and vomiting. Twenty-three women with significant nausea and vomiting in the first 14 weeks of pregnancy were enrolled in a randomized, crossover study comparing an active SAS unit and an inactive placebo unit. Twenty-one women experienced improvement in symptoms, 20 (87%) with the SAS unit and 10 (43%) with the placebo device. Nine women had an improvement with both devices. Eleven women reported an improvement with SAS only, while one woman had placebo improvement only. SAS applied to the wrist can effectively improve pregnancy-induced nausea and vomiting as compared to a placebo device.
本研究考察了通过手腕掌侧进行感觉情感刺激（SAS）对妊娠引起的恶心和呕吐的影响。23名在妊娠前14周有严重恶心和呕吐症状的女性参与了一项随机交叉研究，该研究比较了一个有源SAS装置和一个无源安慰剂装置。21名女性症状有所改善，使用SAS装置的有20名（87%），使用安慰剂装置的有10名（43%）。9名女性使用两种装置症状均有改善。11名女性报告仅使用SAS症状改善，而1名女性仅使用安慰剂症状改善。与安慰剂装置相比，应用于手腕的SAS能有效改善妊娠引起的恶心和呕吐。
