安慰剂研究的最新进展已经证明了大脑改变生理的能力。在这项研究中,我们结合了预期操纵模型与verum和假针灸治疗,以解决:1)如何以及在多大程度上治疗和预期效果-包括主观疼痛强度水平(疼痛感觉等级)和客观生理激活(功能磁共振成像)-相互作用;以及2)无论安慰剂治疗单独给予还是与活性治疗联合给予,预期的潜在机制是否保持相同。结果表明,尽管真针+高期望和假针+高期望引起了同等程度的主观镇痛报告,fMRI分析表明,在右臂施加校准的热痛刺激时,真针引起疼痛相关脑区的fMRI信号降低,我们的研究为针刺的不同机制的存在提供了脑成像证据镇痛和期望诱发安慰剂镇痛。我们的研究结果还表明,在不同的治疗情况下(真针和假针治疗),参与预期的脑网络可能会有所不同。
Recent advances in placebo research have demonstrated the mind’s power to alter physiology. In this study, we combined an expectancy manipulation model with both verum and sham acupuncture treatments to address: 1) how and to what extent treatment and expectancy effects --including both subjective pain intensity levels (pain sensory ratings) and objective physiological activations (fMRI) -- interact; and 2) if the underlying mechanism of expectancy remains the same whether placebo treatment is given alone or in conjunction with active treatment. The results indicate that although verum acupuncture + high expectation and sham acupuncture + high expectation induced subjective reports of analgesia of equal magnitude, fMRI analysis showed that verum acupuncture produced greater fMRI signal decrease in pain related brain regions during application of calibrated heat pain stimuli on the right arm. We believe our study provides brain imaging evidence for the existence of different mechanisms underlying acupuncture analgesia and expectancy evoked placebo analgesia. Our results also suggest that the brain network involved in expectancy may vary under different treatment situations (verum and sham acupuncture treatment).
