Reflexology uses manual pressure applied to specific areas of the feet and sometimes the hands or ears, which allegedly correspond to particular areas or organs of the body.
It is thought the organs of each half of the body are represented on the sole of the corresponding foot. Reflexologists believe health can be assessed by examining the feet to detect imbalances or blocks to energy flow, expressed as tenderness or feelings of grittiness or crystal formation. Practitioners claim that stimulating these areas with pressure or massage can influence bodily functions.
Reflexology is thought to reduce stress, improve circulation, eliminate toxins and promote metabolic homeostasis.
Chronic benign conditions
However, sceptics point out there is no known neurophysiological basis for connections between organs and specific areas of the feet.
Reflexologists treat mostly chronic benign conditions, including asthma, arthritis, back and neck pain, chronic fatigue, digestive problems such as irritable bowel syndrome and constipation, insomnia, migraine and headaches, menopausal symptoms, sinusitis and stress-related disorders.
During a session, a medical history is usually taken before bare feet are examined. Tender or gritty areas are massaged. The strength of pressure varies between practitioners. For lubrication, therapists may use talc or oil. Some use sticks to apply extreme pressure, which can be moderately painful.
Weekly treatments are often recommended, as a course of six to eight sessions. For chronic conditions, follow-up treatments may be offered.
One trial found it superior to placebo reflexology for treating premenstrual symptoms, while other studies have found no advantage of reflexology over non-specific foot massage for menopausal symptoms, irritable bowel syndrome or asthma (see table below).
Beneficial effects on blood glucose in diabetics have been demonstrated, while patients with multiple sclerosis had improved motor, sensory and urinary symptoms after 11 weeks of reflexology compared with non-specific foot massage.
A large observational study found 81 per cent of patients with headache reported cure or improvement at three months follow-up. However, reflexology had no effect on serum cortisol during surgery, or on leg circumference in pregnant women with leg oedema. Trial results have tended to be negative when placebo effects were adequately controlled and positive when this was not the case.
Foot reflexology is contraindicated in foot conditions such as gout, ulceration or vascular disease. Those with bone or joint conditions of the feet or lower leg should be treated cautiously.
Adverse effects include fatigue, changes in micturition or bowel function and allergy to lubricants.
