The purpose of this study was to develop a sinusoidal rotatory chair systim for evaluating the vestibular function in patients suffered from vertigo with vestibualr disorders. The sinusoidal rotatory chair system is composed of a rotatory chair system and softwares. Maximum velocity of the rotatory chair was upto 60 degree per second and frequency range was 0.01 to 0.64 Hz. To evaluate the vestibular function in vertigo patients, vestibuloocular reflex was measured by sinusoidal rotation of the whole body about vertical axis in the darkness, and optokinetic nystagmus, visual vestibuloocular reflex , and visual supression test were also performed. Eye movement was measured by means of a electronystgmograph amplifier through Ag-AgCI surface electrodes. Gain, phase, and symmetry were obtained from analysis of the eye movement ineuced by vestibular or visual stimulation. In healthy adults, sinusoidal rotation of the shole body produced nystagmus, of which gain was directly proportional to the velocity of stimulation. The gain of visual vestibuloocular reflex was greater than that of vestibuloocular reflex or optokinetic nystagmus, and it was suppressed markedly by visual suppression test. These results suggest that the sinusoieal rotatory chair system which was developed by this study can evaluate the vestibular function quantitatively, also this system is very useful to diagnose the vertigo patients with vestibular disorders and to estimate the vestibualr function during recovery from vertigo.

Easy check system for cardiac function was developed for computer user n this study. EKG amplifier was designed to remove a common noise and muscle noise. EKG pattern, and calculated real time heart rate and probability of arrhythmia were displayed in personal computer. This system would be an effective tool for checking cardiac function in everyone using computer.

The purpose of this study was to develop a program for analysis of eye movement on balance. Gain, phase and symmetry in eye movement were calculated automatically by softwere algorithm with C. It was concluded the algorithm established in this study will improve accuracy in evaluating balance function.
