ABSTRACT:
A pain measurement system is capable of accurately and reliably measuring the magnitude of temporary pain in a patient while reducing burdens on the patient during pain measurement. The pain measurement system has a system assembly including a controller that controls an electric stimulus signal output unit to apply a pulse current which increases with time through an electrode. The value of the pulse current is recognized as a minimum sensed current value when a first signal is received. The electric stimulus signal output unit is then controlled to apply, through the electrode, a pulse current having a current value which increases from a predetermined initial value stepwise by nX (where X represents the minimum sensed current value and n represents a positive rational number). The current value of the pulse current is recognized as a pain-commensurate current value when a second signal is received.
