Much of the research on Reiki so far has been conducted with a focus on pain reduction, anxiety and depression. This is not to say that Reiki only helps these things, but as research in the field of Reiki is relatively new, scientists tend to start with just a few symptoms and focus on these due to the costs of trials and ethics around treating patients with serious conditions in such trials.

About the Research

Research into Reiki and related complementary therapies is continuing. Studies vary considerably in their design, sample size, treatment methods and outcomes, so their findings need to be considered in context.

The studies below provide a starting point for exploring the research. They include investigations into Reiki itself, as well as related approaches such as Healing Touch, Therapeutic Touch and massage. Findings from one therapy should not automatically be assumed to apply to another.

Where possible, we link to the original publication so that you can review the study’s methods, results and conclusions for yourselves. The inclusion of a study does not necessarily mean that JRUKA endorses all of its findings or that Reiki has been established as an effective treatment for a particular medical condition.

Reiki Research Studies

The following studies investigate Reiki directly, including its use alongside conventional care and its potential effects on symptoms such as pain, anxiety and fatigue.

Immediate symptom relief after a first session of massage or Reiki in hospitalised patients

Published: 2018
Research topic: Pain, nausea, fatigue, anxiety, depression and wellbeing
Study setting: Rural academic medical centre, United States

What the study investigated

This five-year clinical experience study examined changes in symptoms after one session of Reiki or massage among hospitalised patients who requested or were referred to the healing arts team.

What the researchers reported

Patients experienced improvements in symptoms including pain, nausea, fatigue, anxiety, depression and overall wellbeing. The reported improvements were similar for Reiki and massage in both cancer and non-cancer patients. The researchers also reported greater improvements in fatigue and anxiety following Reiki than massage.

Research context

This was a clinical experience study rather than a randomised controlled trial. Its findings provide useful information about the reported patient experience but should be considered alongside other research.

Reiki research referenced in Energy Medicine East and West

Published: 2011 book reference
Research topic: Pain, blood pressure and immune function

What the reference discusses

In Energy Medicine East and West, John A. Ives and Wayne B. Jonas discuss research into energy medicine approaches, including Reiki. The book references studies examining outcomes such as pain, blood pressure and immune function, including randomised controlled trials.

Research context

This is a secondary reference to research rather than a single original study. The specific studies and their methods should be reviewed before drawing conclusions about Reiki’s effectiveness.

Effects of Reiki vs Physiotherapy on lower back pain

Published: 2018
Research topic: Lower back pain and activities of daily living
Study design: Randomised controlled trial

What the study investigated

Sixty patients with intervertebral disc hernia were randomly assigned to receive Reiki, physiotherapy or drug treatment. The study examined pain levels and activities of daily living.

What the researchers reported

The study reported that both Reiki and physiotherapy produced greater reductions in pain than drug treatment. Reiki and physiotherapy produced similar levels of pain reduction.

Research context

The study was relatively small, and its findings should be considered alongside other research before drawing broader conclusions.

The effects of Reiki and back massage on women's pain and vital signs after abdominal hysterectomy

Published: 2021
Research topic: Pain, analgesic use and vital signs
Study design: Randomised controlled trial

What the study investigated

This study compared Reiki, back massage and a control group among women following abdominal hysterectomy.

What the researchers reported

The researchers reported statistically significant differences in pain intensity and analgesic use between the groups. They also reported differences in vital signs, with the Reiki group showing decreases in the assessed measures.

Research context

The findings relate to the specific study population and intervention. Further research is needed to understand how the results may apply in other settings.

Cancer pain relief after Healing Touch and Massage

Published: 2018
Research topic: Cancer pain
Therapies studied: Healing Touch and Oncology Massage
Study design: Comparative clinical study

What the study investigated

This study compared Healing Touch and Oncology Massage in 572 cancer patients, examining their effects on pain.

What the researchers reported

Both Healing Touch and Oncology Massage were associated with significant reductions in pain. The study reported that pain relief tended to occur immediately, within one session.

Research context

This study investigated Healing Touch and Oncology Massage, not Reiki. Its findings should therefore not be presented as direct evidence of Reiki’s effectiveness.

The effects of Therapeutic Touch on back pain in adults on a neurological unit

Published: 2018
Research topic: Chronic back pain
Therapy studied: Therapeutic Touch
Study design: Experimental pilot study

What the study investigated

This study involved 29 adults with chronic back pain. Fourteen received standard drug treatment, while 15 received standard treatment plus four healing sessions over four consecutive days.

What the researchers reported

The study reported greater reductions in pain in the group receiving the additional healing sessions. The researchers concluded that the findings indicated a potentially meaningful effect that warranted further research.

Research context

This study investigated Therapeutic Touch, not Reiki, so its findings should not be presented as direct evidence of Reiki’s effectiveness.

Further Research

Review of randomised controlled studies of biofield therapies

Published: 2014
Research topic: Biofield therapies, including Reiki

What the review investigated

A pilot review examined randomised controlled studies of several biofield therapies, including external qigong, Healing Touch, Johrei, Reiki and Therapeutic Touch.

What the researchers reported

The review examined 18 trials and reported that approximately two-thirds demonstrated at least partial effectiveness. The authors concluded that further research was warranted.

Research context

This was a review of several different therapies, not Reiki alone. The findings should therefore be interpreted as part of the wider research landscape rather than as definitive evidence for Reiki.

Research Disclaimer

The studies and summaries on this page are provided for information purposes. Research into Reiki and related complementary therapies varies in quality and design. The inclusion of a study does not necessarily mean that JRUKA endorses its findings or that Reiki has been established as an effective treatment for a particular medical condition.

Reiki should not be used as a substitute for appropriate medical care. Anyone considering Reiki alongside medical treatment should discuss this with their healthcare professional.
