The effects of Okada Purifying Therapy (OPT), a form of subtle energy (biofield) therapy that originated in Japan, were investigated. Electroencephalograms and the Profile of Mood States scores were measured using a crossover design during OPT and placebo sessions.
Nineteen (19) healthy Japanese adults (mean age±standard deviation: 40.8±11.2 years; 10 females) with no previous experience of biofield therapy participated in this study.
Each session lasted 15 minutes. A single-blind, randomized design with a protocol consisting of regular cycles with eyes open followed by eyes closed was used. The power spectral value was calculated in θ (4.0-7.9 Hz), α (8.0-12.9 Hz), and β (13.0-29.9 Hz) frequency ranges.
The power spectral value of the α band at F(p1), F(p2), F(7), F(z), F(8), C(3), C(z), C(4), and P(z) increased significantly in the OPT session compared with the placebo session. Mood state was improved after both sessions, and no significant difference was found between the two sessions.
OPT was more effective in increasing α waves in the frontal and central cortex than a placebo treatment.
研究源于日本的微妙能量（生物场）疗法之一——冈田净化疗法（OPT）的效果。采用交叉设计，在 OPT 和安慰剂治疗期间测量脑电图和心境状态剖面图评分。
19 名（19 名）无生物场治疗经验的健康日本成年人（平均年龄±标准差：40.8±11.2 岁；10 名女性）参加了这项研究。
每次治疗持续 15 分钟。采用单盲、随机设计，方案包括睁眼常规循环，随后闭眼。计算θ（4.0-7.9 Hz）、α（8.0-12.9 Hz）和β（13.0-29.9 Hz）频段的功率谱值。
与安慰剂治疗相比，OPT 治疗在 F(p1)、F(p2)、F(7)、F(z)、F(8)、C(3)、C(z)、C(4)和 P(z)的α频段的功率谱值显著增加。两种治疗后情绪状态均得到改善，但两种治疗之间无显著差异。
与安慰剂治疗相比，OPT 在增加额中和中央脑区的α波方面更有效。
