Reiki (pronounced "RAY-kee") is a form of "energy healing" that uses vibration drawn through the practitioner into the recipient, in accordance with the recipient’s need. Proponents hypothesize that Reike re-establishes the energy balance in areas of the body associated with discomfort, thus promoting healing and increasing quality of life. Researchers have evaluated Reike in patients with cancer for its impact on anxiety, depression, pain, and fatigue.

PHASE OF CARE: Active antitumor treatment
APPLICATIONS: Palliative care
Interventions considered to be BT were healing touch, Reiki, and therapeutic touch. The effect on pain was examined in seven studies. There were some mixed findings, but most showed a reduction in pain over short time periods. Fatigue was assessed in five studies. These demonstrated fatigue reduction post-treatment, but data were conflicting over a longer period of four to eight weeks. Anxiety and depression were examined in seven studies. All but one found a significant reduction in mood disorders, but a study comparing Reiki, sham Reiki, and usual care found no difference between the sham and actual Reiki groups. Most studies were of descriptive or quasi-experimental design; potential confounding variables were not examined, and placebo effects could not be ruled out.
Studies using biofield therapies for relief of pain, anxiety, fatigue, and depression generally showed benefit; however, the evidence is not strong due to the limitations of the studies included.
Low-quality design studies and the short duration of study follow-up
BT therapies have not demonstrated effectiveness in well-designed clinical studies; however, though it is weak, evidence suggests potential benefit. There were no adverse effects of these interventions reported. Biofield therapies are not expensive and are low-risk, so they can be considered in the management of cancer-related symptoms. Well-designed clinical trials are needed to establish efficacy.
Joyce, J., & Herbison, G.P. (2015). Reiki for depression and anxiety. Cochrane Database of Systematic Reviews, 4, CD006833.
Studies reviewed did not ensure that patients studied had depression or anxiety, so validity of examining impact of Reiki intervention on these problems is questionable. Two of the three studies had high risk of bias. No studies showed a statistically significant benefit.
There is insufficient evidence to evaluate efficacy of Reiki for anxiety and depression.
The evidence regarding effects of Reiki for anxiety or depression is insufficient to draw any conclusions. If Reiki is to be seen as a serious option for treatment, well-designed research to investigate effects is needed.

To determine the feasibility of testing a Reiki intervention, a complementary therapy, on women undergoing breast biopsy; to determine the effectiveness of a Reiki intervention in the sample
Two-group design: conventional care group (CCG) and Reiki intervention group (RIG)
Diagnostic
Randomized controlled single-blind trial
Neither group displayed significant distress (as operationalized by the three measures) either before or after breast biopsy. Likewise, the study showed no significant difference in any of the measures between groups (RIG and CCG) over time. Over time (pre- to post–breast biopsy), the A state did not decrease significantly in either group (F (2) = 4.78, p = 0.0119) in regard to the HADS total (F (1) = 6.18, p = 0.0187) or HADS anxiety subscale (F (1) = 12.96, p = 0.0011).
One cannot conclude that Reiki was an effective intervention for reducing biopsy-related distress.
Findings do not support the effectiveness of Reiki under the conditions of the study.
