SCOTS researchers say they have shown for the first time that reflexology can have an actual effect on the way a healthy person's heart functions.

Therapists have long believed the foot can be mapped to individual organs and that by massaging particular points, specific organs will receive more blood.

Now experts have carried out a study into the technique, testing the upper left ball of the sole that is said to map to the heart.

They discovered that healthy patients who underwent the treatment recorded a change in their heart function when that area of their feet was massaged. Reflexology on other parts of their feet had no such effect.

Cardiology patients who had problems with their blood flow, meanwhile, did not experience any change in their heart function.

Stirling University PhD researcher Jenny Jones, who carried out the work with Professor Steve Leslie, a cardiologist from the Cardiac Unit at Raigmore Hospital, said: "Reflexology is unique because it makes quite specific claims that it increases blood flow and this is something you can scientifically test.

"In our experiment with healthy people there was an inexplicable change in the heart function which occurred only when the heart reflex point area was massaged. We have no idea what caused this change, so we have applied for funding to investigate this further.

"Interestingly, there was no effect on the hearts of cardiology patients; however, all the patients found the treatment to be really relaxing."

The research, published in the journal Complementary Therapies in Clinical Practice, will now be extended.

Ms Jones said: "There are limitations to what we can do with clinical medicine but there has not been much scientific research available on complementary therapies such as reflexology to help people decide if they work or not"
