Diter Oy was started after the promising running career of our present Chairman of the Board, Mr. Reima Karsikas, ended to a serious knee injury in 1973.
Falling down in full running speed caused total peroneus paresis. In order to maintain the ability to walk and to stimulate the paralysed muscle group Reima Karsikas developed a stimulation device and rehabilitated himself to the surprise of the doctors.

Diter´s first product was indeed a device for diagnosing and treatment of peripheral paresis. This device was launched in 1977. During the past more than twenty years Diter has designed and manufactured more than 30 different therapy equipment.
In 1988 Diter was awarded with the Idea Of The Year Award by the Chamber of Commerce for developing the first ultrasound treatment head which functions at three different frequencies.
