Abstract
Identifying a vibrotactile perception threshold of different mechanoreceptors at a skin site of a subject by detecting sensory deficits in peripheral nerves and, in particular, those associated with neuropathy in the fingers or other parts of the body. Controlling and monitoring of the static dynamic contact force between the human skin site and a vibrating probe which transmits a frequency signal to a receiver for measuring the spatial position of the transmitted signal, whereby a human feedback device records the signal and adjusts for continuous contact force between the skin site and vibrating probe.

7. In a method for testing or screening of peripheral neuropathies at a skin site of a subject, the method employing an apparatus having a support device for supporting a body part containing the skin site of a subject to be tested, a vibration generating device having a contact element for positioning in the skin site, a frequency generating device connected to the vibration generating device, a control circuit, a switch, and a human feedback device, the improvement in the method comprising:
-
controlling contact between the vibration generating device and the skin site;
vibrating the vibration generating device at specific predetermined frequencies;
supplying a known discrete frequency signal between the frequency generating device and vibration generating device;
modifying amplitude of the frequency signal controlling the circuit in an ascending and descending mode by a subject actuating the switch providing response signals to the control circuit; and
obtaining a threshold signal value from the response signals keeping continuous contact force between the skin site and contact within a predefined range. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
