The effectiveness of reflexology on mental health in cancer patients: A systematic review and meta-analysis of randomised controlled trials

Abstract

Background and purpose: The current body of research examining the effectiveness of reflexology in patients with cancer have predominantly focused on managing physical symptoms and treatment side effects. This review aimed to synthesise evidence from randomised controlled trials (RCTs) examining the effectiveness of reflexology on mental health outcomes in people with cancer. Methods: RCTs published in English and measuring stress, anxiety, depression or quality of life (QoL) were included. Eligible RCTs were identified through search of MEDLINE, Embase, Emcare, PsycINFO, Scopus, the Cochrane Library, OTseeker, PEDro (18 June 2021) and Google and Google Scholar (21 June 2021). The Critical Appraisal Skills Programme Randomised Controlled Trials Checklist was used to assess risk of bias. Meta-analysis and narrative synthesis were undertaken. The certainty of evidence was assessed by using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework. Results: Fifteen RCTs (1356 adult participants) were included. Evidence for stress and anxiety (primary outcomes), as well as depression and QoL (secondary outcomes), were mixed and conflicting. The certainty of the evidence was low to very low. Conclusion: An unequivocal recommendation supporting reflexology cannot be made. Greater utilisation of well-established reporting guidelines, together with increased investment in well-designed, high-quality clinical research are required.
