Although the Original Ingham Method® and chart is world-wide used other prominent reflexology trainers in various countries contributed to the development of a number of new reflexology techniques.
The nurse and physiotherapist, Eunice Ingham worked for Dr. Riley in St. Petersburg, Florida.
Zone Therapy/Foot Reflexology
In 1925, Ingham developed zone therapy into foot reflexology.
In the early 1930’s she started developing her foot reflex theory and applied pressure to particular points across the soles of the feet. She discovered that this technique stimulated and helped the body to heal, rather than to provide only pain relief.
After extensive research she found that the feet and hands were especially sensitive to pressure. After extensive research Ingham made a distinct separation between working on reflex points and zone therapy.
Map of the feet
She developed a map of the feet with all the corresponding organs and glands of the body and called it compression therapy before naming it reflexology.
She developed the alternating pressure technique used by most reflexologists today and became known as the mother of modern reflexology and a trainer of reflexology. She travelled around the USA, gave lectures and seminars in Foot Reflexology first to medical staff, and then to non-medical practitioners.

She became interested in the therapy Reflexology and decided to train with Eunice Ingham in 1958 and took the Ingham method and Zone therapy back to Europe.
Due to her own medical training, she understood the connection between the client and his/her reflecting areas on the feet, and created a new technique, Reflexotherapy known as RTF. She treated a wide range of ailments and several disorders and proved the effectiveness of the therapy RTF.
She founded 15 schools in Germany and abroad and trained Reflexotherapy of the Feet (RTF) to thousands of practitioners with a medical- therapeutic background.

Inge Dougans born in Denmark qualified in 1981 as a Reflexologist in Copenhagen and emigrated to South Africa in October 1981 where she opened a private reflexology clinic.
In 1983 she started the training institution, the International School of Reflexology and Meridian Therapy (now known as the International Academy of Reflexology and Meridian Therapy), in Johannesburg and incorporating the Chinese Meridian Theory. She lectures all over the world, including Denmark, Germany, Italy and Poland.
Dougans also developed the Vacuflex System, [consisting of two boots & 14 suction cups]. This system applies pressure to the whole foot and stimulates all the reflex areas at the same time in five minutes. The suction cups are used to stimulate the acupuncture points on the meridians. The system is in fact a modern technology equipment that can be combined with the normal reflexology treatment.
