Reiki for cancer? No!

This review was aimed at analyzing the scientific evidence on Reiki intervention as a nursing care strategy for people with cancer. For this purpose, the researchers searched six databases, including primary studies, in Portuguese, Spanish and/or English, about the evidence on the use of Reiki intervention as a care strategy for cancer patients, totaling five publications.

The included studies suggest potential benefits of Reiki intervention, such as pain relief, reduction of physical symptoms (fatigue and insomnia) and improvement in emotional aspects, such as anxiety and stress. However, the results are still limited in terms of methodological robustness and generalizability.

The Brazilian authors concluded that, although the findings indicate beneficial effects of Reiki in people with oncological diseases, there is a limited production of clinical trials aimed at the application of this therapy in clinical nursing practice. Reiki can be considered a complementary strategy in nursing care, as long as it is integrated into an individualized therapeutic plan. It is recommended that studies with greater methodological rigor be carried out to evaluate the effectiveness of Reiki applied by oncology nurses.

The authors explain that “Reiki is a practice that uses the laying on of hands and symbols to channel universal life energy to recharge, realign and rebalance the human energy field. Its objective is to undo energetic blockages that compromise the flow of vital energy, and maintain harmony between the body, mind and spirit.” With just 2 sentences, the authors inply that Reiki has a sound scientific basis which they do not question in their paper at all. Yet phenomena such as live energy, regarging, realigning and rebalancing human energy fields, energetic blockages in the human body, flow of vital energy could not be less scientific. In fact, they are pure fantasy and have no basis in reality.

The authors also explain that 20 % (n=1) of the included studies were qualitative, 20 % (n=1) were quasi-experimental, 20 % (n=1) were reports of professional experience, and 40 % (n=2) consisted of randomized clinical trials (RCTs). On closer scrutiny, none of the RCTs was sufficiently rigorous to allow firm, positive conclusions. In other words, there is no good evidence and the conclusion that Reiki is beneficial for cancer patients is nonsense.

The authors note that, in 2017, with the publication of Ordinance No. 849, of March 27, Reiki was officially included in the Brazilian public health network. In view of the above mentioned lack of plausibility combined with a lack of effectiveness, this inclusion seems wholly irresponsible.
