Device for inducing and registering imbalance
First Claim
Patent Images
1. A device for registering and evaluating the response of a human subject to induced imbalance comprising a horizontal platform means for accommodating said human subject;
- said platform means being adapted for controlled linear displacement in a horizontal plane to cause said induced imbalance and comprising a horizontal surface mounted on linear bearings which engage rails and connected to a motor through means for translating rotation of the motor into linear motion to cause said displacement at a controlled speed and acceleration and for controlled duration and distance;
means for detecting said imbalance and the response of said subject thereto and for producing signals which characterize said imbalance and response;
means for transmitting said signals to evaluation, display and recording means for registering and evaluating said imbalance and response thereto by said subject.
