Abstract
Objectives: Reflexology has become one of the most frequently used treatment modalities within complementary medicine. This level of popularity makes it desirable for healthcare professionals to understand the essential facts about it. The aim of this article is therefore to review the existing literature on reflexology and compile the facts. Particular emphasis is put on clinical trials. Methods: Two independent, computerised literature searches were performed. All articles with factual information were included. Various other sources of information were used as well. Particular emphasis was on data relating to prevalence, effectiveness, safety and costs. For reviewing the effectiveness of reflexology, only controlled clinical trials were considered for a systematic review. Results: The prevalence of reflexology is variable. Only few controlled clinical trials on the subject have been published. Collectively they do not support the motion that reflexology is associated with specific therapeutic effects. The data on safety and costs are similarly insufficient. Conclusion: Reflexology is popular, yet little factual information exists about it. On the basis of the existing data, it seems possible, even probable, that its perceived benefit is brought about by non-specific effects.
