Abstract:
An automated device is described which enables operator independent measurement of pain threshold. Pressure is applied across a joint of the digit by means of a controlled pneumatic actuator. Testing 10 normal subjects indicated good reproducibility (r2 = 0.75, one-way analysis of variance).
