Eight thousands five hundreds and ninty-two pupils of 8 primary schools and 6 secondary schools in the Kanagawa prefecture had been examined by specially designed equilibrium function tests in a 4-year period from 1975 to 1978. The equilibrium examinations included one foot standing test in foreward tilted posture with eyes opened, walking test with eyes closed, twice step-rotating test with eyes closed and modified Heaths rail-walking test. A balance board test was added in only 1978, since the boards are popular equipments in the schools in Japan. The mean value and standard deviation of each test result were evaluated.The relationship between equilibrium function and the other related factors, such as sex, school grade, Rohrers index, school records and answers to 15 questionaires about daily lives in each pupil was studied by using a FACOM 230-38 electronic computer.The normal ranges of the test results reported in our previous papers were reconfirmed. It is assumed that each equilibrium function test might be important to find out the abnormality of equilibrium from different aspects and the test results are closely related to the labyrinthine function, vision, cerebellar motor function, autonomic nervous system, cardio-vascular system and psychosomatic state in test subjects.
