An Application of Strain-Gage-Type Instruments to the Analysis of the Equilibrium Function in human Subjects and Animals

Abstract

First of all introducing the principles of the strain-gage and also the characteristics of the strain-gage-type instruments hitherto described, two of the instruments specially devised by the authors for the purpose of precise recording of the body movements in human subjects or animals under various conditions, such as labyrinthine or visual stimulation, have been presented in detail. Using an unbonded strain-gage-type linear accelerometer, or the two newly devised strain-gage-type instruments, together with either electronystagmograph or electromyograph, the equilibrium function in human subjects or animals has been successfully analysed.
