Effects of Reiki on Mental Health Care: A Systematic Review

Complementary and Alternative Medicine (CAM) Practices: A Narrative Review Elucidating the Impact on Healthcare Systems, Mechanisms and Paediatric Applications

While research on complementary and alternative medicine (CAM) for the general population is expanding, there remains a scarcity of studies investigating the efficacy and utilisation of CAM practices, specifically in the paediatric population. In accordance with the World Health Organization (WHO), the prevalence of the parental utilisation of CAM in their dependents is estimated to reach up to 80%. This literature review identified broad, heterogeneous, and inconclusive evidence regarding CAM's applications and effectiveness, primarily attributed to variance in sociodemographic factors and differences in national healthcare systems. Additionally, the review identified a lack of consensus and polarised positions among mainstream professionals regarding the mechanisms of action, applications, and effectiveness of CAM. This narrative review presents varied results concerning the efficacy of most CAM therapies and their applications; however, some evidence suggests potential benefits for acupuncture, yoga, tai chi, and massage in improving physical and mental health. Moreover, the available evidence indicates that meditation may enhance mental health, while reiki may only influence patients' perceptions of comfort. In light of the intricate and multifaceted nature of herbal medicine, it is imperative to assess its efficacy on a case-by-case basis, taking into account the specific compounds and procedures involved. This comprehensive review serves as a valuable resource for health professionals, offering guidance for personalised healthcare approaches that consider the values and beliefs of patients, thereby facilitating integrated, evidence-based practices aimed at enhancing the quality of healthcare services and patient satisfaction.

Does Reiki Benefit Mental Health Symptoms Above Placebo?

Background

Reiki is an energy healing technique or biofield therapy in which an attuned therapist places their hands on or near the client's body and sends energy to the client to activate the body's ability to heal itself and restore balance. It was developed in Japan at the end of the 19th century by Mikao Usui of Kyoto. Given the enormous international socioeconomic burden of mental health, inexpensive, safe, and evidenced-based treatments would be welcomed. Reiki is safe, inexpensive, and preliminary research suggests it may assist in treating a wide variety of illnesses. Given that Reiki is a biofield therapy, growing in use, and not yet accepted by the dominant biomedical paradigm, it is important to establish its effectiveness over placebo. This study aimed to examine Reiki's effectiveness over placebo in treating symptoms of mental health and to explore parameters for its effectiveness.

Method

A systematic review of randomized placebo-controlled trials (RPCTs) examining Reiki's effectiveness in treating symptoms of mental health in adults was conducted through a systematic search of PubMed, PsycINFO, MEDLINE, CINAHL, Web of Science, Scopus, Embase, and ProQuest. Fourteen studies met the inclusion criteria, and risk of bias was assessed using Cochrane's Revised ROB 2 assessment tool. This was followed by a grading of recommendations, assessment, development and evaluations (GRADE) assessment.

Results

The evidence to date suggests that Reiki consistently demonstrates a greater therapeutic effect over placebo for some symptoms of mental health. The GRADE level of evidence is high for clinically relevant levels of stress and depression, moderate to high for clinically relevant levels of anxiety, low to moderate for normal levels of stress, and low to moderate for burnout, and low for normal levels of depression and anxiety.

Conclusion

The results suggest that, Reiki may be more effective in treating some areas of mental health, than placebo, particularly if symptoms are clinically relevant. To date, there are a small number of studies in each area, therefore findings are inconclusive and, more RCTs controlling for placebo in Reiki research are needed. Most included studies were also assessed as having a risk of bias of some concern. Incorporating Reiki as a complementary treatment to mainstream psychotherapy for depression, stress, and anxiety may be appropriate.

Complementary therapies in substance use recovery with pregnant women and girls

Objectives:

Supporting women and girls who are pregnant and experiencing substance use challenges is a high priority for researchers, clinicians, and policymakers. Complementary therapies (CTs) can be effective forms of treatment in some contexts and populations; however, research on the use of CTs in substance use recovery with pregnant women and girls is scarce. To fill this gap, we conducted a mixed methods study using survey data collected at a women’s recovery center in Canada. Our objectives were to describe CTs provided at the program; identify what CTs are perceived by participants as most/least positive; and explore factors that may impact participant experiences with CTs.

Methods:

We analyzed feedback responses from 255 women and girls ( Mage = 27.5 years, range 15–64) using Pearson chi-square tests, logistic regression, and inductive content analysis.

Results:

The most frequently provided CTs were yoga, energy-related activities (e.g. reiki, reflexology), and meditation. Among the most common CTs, participants provided the highest endorsements for massage and physical activity, and the lowest endorsements for yoga and drumming. Across CTs, whether participants looked forward to an activity contributed significantly to whether they found it helpful, would like to do it again, and planned to continue engaging in the activity after leaving the program. Four broad contextual factors were identified that may impact experiences and perspectives about CTs: (1) goodness of fit, (2) self-awareness, (3) growth, and (4) healing and holistic wellbeing.

Conclusions:

This study provides novel evidence on the potential impacts of CTs in substance use treatment for pregnant women and girls, and important contextual factors to consider when implementing these approaches.
