title: Effect of biofield therapy in the human brain.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  OPT was more effective in increasing α waves in the frontal and central cortex than a placebo treatment.
