First Claim
Patent Images
1. An apparatus for testing a threshold of perception of mechanical vibration by producing a mechanical stimulation by vibration of a tappet applied to a patient'"'"'s skin, wherein an amplitude of the mechanical vibration can be varied around a threshold of perception, the apparatus comprising:
- a measuring head, including a housing and a tappet elastically held in the housing and guided for back and forward movement;
a tippet actuating unit attached to the tappet;
an acceleration sensor attached to the tappet and connected to control electronics, the control electronics being attached to the measuring head and including a power amplifier attached to the tappet actuating unit; and
,a patient reaction panel attached to the control electronics, the patient reaction panel including means for receiving a response from the patient to indicate a reaction upon perceiving a mechanical stimulation.
