There is a robust body of research on various forms of healing from around the world. Some of the studies are published in medical and nursing journals, others are available as masters and doctoral dissertations. Daniel J. Benor, MD is a pioneer in compiling published research studies and exploring their implications in his series of books: Healing Research: Volumes I-IV. (See this and other references, below.)

Recent studies
O’Mathuna, D.P. (2000). Evidence-based practice and reviews of therapeutic touch. Journal of Nursing Scholarship, Third quarter, 279-285.
Considers ways in which research can be presented in order to make decisions about therapies and practices, with a critical analysis of some of the reported findings in the literature to date.

Wilkinson, D., Knox, P., Chatman, J., Johnson, T., Barbour, N., Myles, Y., & Reel, A. (2002). The clinical effectiveness of Healing Touch. Journal of Alternative and Complementary Medicine, 8(1), 33-47. 
Healing Touch’s effect on immune function was explored using a repeated measures design with 22 individuals who were randomized to no treatment, standard HT, and HT plus music (HT+) Outcome measures were secretory IgA (sIgA) and self-reports of stress, perceptions of health enhancement, and qualitative questionnaires. The results indicated a significant interaction effect of the treatment stage and the practitioner training level (p<0.021) Stress rating (using a scale of 1-10) was reduced after treatment for both HT and HT+ (p<.000). SIgA also changed significantly in the HT group. In the qualitative analysis relaxation was the most prominent theme and 53% reported pain relief with one having a dramatic reduction in chronic pain experience. Placebo effect was evaluated by including predictor questions. The overall treatment responders did not differ from the non-responders on placebo scores (p=< 0.417)

Woods, D.L. & Dimond, M. (2002). The effect of therapeutic touch on agitated behavior and cortisol in persons with Alzheimer’s disease. Biological Research for Nursing, 4(2), 104-114. 
Found salivary and urine cortisol levels had a decreasing trend over time with 10 patients with Alzheimer’s, which correlated with a significant decrease in overall agitated behavior.

Meta-analyses of healing studies
Abbot, Neil C, Healing as a therapy for human disease: a systematic review, Journal of Alternative and Complementary Medicine 2000, 6(2), 159-169. 
59 RCTs; Small sample sizes in the 15 studies in the dissertations and pilot group may have contributed to the lack of significant effects in 11 of them.

Astin, John A/ Harkness, Elaine/ Ernst, Edzard, The efficacy of "distant healing": a systematic review of randomized trials, Annals of Internal Medicine 2000, 132, 903-910. 
23 studies: 5 with prayer healing, 11 with non-contact Therapeutic Touch, and 7 miscellaneous distant healing approaches. A positive effect was found in 57 percent of these.
For the 16 trials with double blinds, average effect size 0.40 (p < .001). For 10 TT studies meeting selection criteria, average effect size 0.63 (p < .003). For prayer studies effect size 0.25 (p < .009). For "other" studies average effect size 0.38 (p < .073).

Braud, William and Schlitz, Marilyn. A methodology for the objective study of transpersonal imagery, Journal of Scientific Exploration 1989, 3(1), 43-63. 
Electrodermal activity (EDA) – 323 sessions with 4 experimenters, 62 influencers and 271 subjects. Of the 15 studies, 6, (40 per cent) produced significant results. Of the 323 sessions, 57 percent were successful (p = .000023).

Jonas, Wayne B and Crawford, Cindy C. Science and spiritual healing: a critical review of spritual healing, “energy” medicine, and intentionality, Alternative Therapies (Supp) 2003, 9(3), A56-71. Meta-analyses for: 
Intercessory or healing prayer - Of 13 randomized studies, 46% statistically significant effects, mean effect size across trials of .30. Quality of research judged "fair." (Reviewer John Astin)
“ Energy” healing approaches - Of 19 RCTs (all but one on TT) 58% statistically significant, mean effect size .60. Quality judged "poor to fair." (Reviewers Sarah Warber, et al)
Therapeutic qigong - Of 58 studies, almost all reported positive results. Quality of research judged "poor." (Reviewer Juliann Kiang)
Electrodermal Activity - Of 24 studies, 37.5% significant results. Quality of research judged "fair to good." (Reviewer Stefan Schmidt)

Peters, R. (1999). The effectiveness of therapeutic touch: A meta-analytic review. Nursing Science Quarterly, 12(1), 52-61.
Nine studies of the 36 studies identified that were empirically based research studies were used. Therapeutic touch was found to have a positive, medium effect on physiological and psychological variables.

Schlitz, Marilyn/ Braud, William, Distant intentionality and healing: assessing the evidence, Alternative Therapies 1997, 3(6), 62-73. 
19 experiments where one person sought to influence another's electrodermal activity (EDA) (p < .0000007).

Winstead-Fry, Patricia/ Kijek, Jean, An integrative review and meta-analysis of Therapeutic Touch research, Alternative Therapies 1999, 5(6) 59-67. 
Of 29 dissertations and studies addressing efficacy, 19 showed at least partial support for the research hypothesis. The other 10 rejected the hypotheses. Deficiencies in reporting details of the studies make it very difficult to compare studies. A moderate combined effect size was found (0.39) in the 13 studies that included means and standard deviations for treatment and control groups (p < .001).
