reflexology

Reflexology is one of the most popular of all alternative therapies. Anyone who has ever had a session knows why: it is a strangely pleasant and oddly agreeable experience. Reflexologists massage your feet which can be mildly painful but usually is quite relaxing. They look for and subsequently focus on areas of tenderness believing they correspond to specific organs or whole organ systems. Even though few reflexologists would admit to it, they tend to make vague and unreliable diagnoses: if they feel something unusual at a certain point of the sole of your foot, they assume that a certain inner organ is in trouble. Reflexologists even have maps where the sole of a foot is depicted showing which area corresponds to which organ.

The treatment might be enjoyable but the assumptions that underpin it are nonsensical for at least two reasons: firstly, there are no nerve or other connections between a specific area on the sole of a foot and a certain organ. Secondly, the maps which reflexologists employ differ and fail to agree which area corresponds to which organ. Thus there are inconsistencies within the realm of reflexology and there are inconsistencies in relation to the known facts regarding physiology, anatomy etc.

Proponents of reflexology are quite undisturbed by these problems and seem to believe that not their assumptions but science must be wrong. After all, reflexology does work! That is to say that patients perceive benefit from it, pay out of their own pocket for the experience and tend to come back for more.

Several years ago, we asked 8 UK professional organisations of reflexology which conditions they thought could be treated effectively with reflexology. We gave them a list of 25 conditions to chose from, many of which were serious, e.g. cancer and AIDS. Collectively, the organisations felt that 22 of these illnesses would respond to reflexology.

But this is opinion, not evidence! What do the trial data tell us? Is reflexology more than a placebo?

As with many other areas of alternative medicine, controlled clinical trials are scarce; but this is not to say that none at all are available. Our own trial of reflexology for menopausal symptoms failed to show that this therapy has any effects beyond placebo. More recently, we published a systematic review to evaluate all of the 23 studies that had been published at that stage. They related to a wide range of medical conditions and their methodological quality was often poor. Nine high quality randomised clinical trials (RCTs) generated negative findings. Eight RCTs suggested that reflexology is effective for the following conditions: diabetes, premenstrual syndrome, cancer patients, multiple sclerosis, symptomatic idiopathic detrusor over-activity and dementia. These studies, however, were wide open to bias. Therefore, our conclusions had to be cautious: the best clinical evidence does not demonstrate convincingly reflexology to be an effective treatment for any medical condition.

For you and me, this simply means that there is currently no good evidence to suggest that reflexology works. But the story does not end here. There will be more studies and enthusiasts are most likely to concede that our conclusions were incorrect. In fact, a further trial has just become available.

This new single-blind, randomized and placebo controlled study included 20 moderately to severely affected multiple sclerosis patients. Each participant received for 8 weeks, 1 hour per week of either reflexology or sham reflexology. The primary outcome measure was the Multiple Sclerosis Impact Scale at baseline, 8 weeks and 16 weeks. The results revealed improvements in both groups but no statistically significant differences between the two groups at either 8 or 16 weeks. The conclusions of the investigators were clear: The results do not support the use of reflexology for symptom relief in a more disabled multiple sclerosis population and are strongly suggestive of a placebo response.

There is, of course, nothing wrong with a relaxing foot-massage; it is agreeable, no doubt, and if someone wants to pay for the luxury, why not? By contrast, there is a lot wrong with reflexology, I think. A foot-massage is not administered under the pretence of generating any specific therapeutic effects. Reflexologists, however, claim they can exert highly specific effects on inner organs, influence the natural history of a wide range of diseases, and provide reliable diagnoses. They thus mislead their clients. This is not just wrong, it also has the potential to do serious harm. I believe it is time to end this nonsense.
