The parallel swing is a useful tool to collect data on the functioning of the otolithic system. In 12 human subjects experiments were conducted with the parallel swing to determine the threshold of perception for movements of this swing. The effect of different body positions on this threshold was also determined.
In another series of experiments the amplitude of the sinusoidal compensatory eye movements was investigated when the swing was oscillating with an amplitude of 12.5 cm, as well as with an amplitude of 25 cm.
