Animal studies to show the benefit of Reiki or Massage have not been conducted to the extent that human studies have. Some have been on laboratory animals, which although useful information, I feel I do not want to condone and include on here. A small number are emerging but much more work needs to be done.
The following studies have been published on PubMed® a government website which comprises more than 32 million citations for biomedical literature from MEDLINE, life science journals, and online books. It has been available to the public online since 1996, PubMed was developed and is maintained by the National Center for Biotechnology Information (NCBI), at the US National Library of Medicine (NLM), located at the National Institutes of Health (NIH)
I have included some studies which demonstrates on humans the benefits that Reiki can give alongside massage as well as Reiki alone.
I will include other relevant ones as they are published.
- Reiki's effect on patients with total knee arthroplasty was looked at immediate postoperative period, as managing postsurgical pain with pain medication can contribute to complications. The hospital was researching whether a more effective approach might include a combination of pharmacologic and nonpharmacologic measures, such as Reiki therapy.
When you include Massage with Reiki, you can sometimes get better results.
- Using Massage or Reiki in Hospitalized patients to give immediate Symptom Relief After a First Session. Most controlled studies and practice-based reports include oncology and surgical patient populations but this one was in a more heterogeneous hospitalized patient population in A 396-bed rural academic and tertiary medical centre in the United States.
