A nerve stimulation measurement device comprising: a responding section being configured to perform a response operation when a subject to whom an electrode section that applies electrical stimulation is attached senses the electrical stimulation; and a controlling section being configured to supply a stimulation current which stepwise increases or decreases, to the electrode section, and being configured to obtain a sensitivity threshold that is a stimulation current from which the subject senses the electrical stimulation, from a situation of response to each stepwise supply, wherein in a case where a stimulation current which stepwise increases is to be supplied to the electrode section, the controlling section stepwise increases the stimulation current according to a predetermined increment, and, wherein in a case where a stimulation current which stepwise decreases is to be supplied to the electrode section, the controlling section stepwise decreases the stimulation current according to a predetermined decrement, wherein the controlling section is configured to perform a session process in which the supply of the stimulation current to the electrode section is repeated until a response is not confirmed, and obtains a minimum current value that is a minimum stimulation current at which the response can be confirmed, and, wherein in a case where a range where minimum current values that are obtained in sessions correlate with one another is set as a predetermined range of an effective current, and a number of sessions that are required for obtaining the sensitivity threshold is set as a number of valid sessions, when, within the predetermined range of the effective current, there are the minimum current values a number of which is equal to or larger than the predetermined number of valid sessions, the controlling section is configured to obtain the sensitivity threshold based on the minimum current values within the predetermined range of the effective current. a responding section being configured to perform a response operation when a subject to whom an electrode section that applies electrical stimulation is attached senses the electrical stimulation; and a controlling section being configured to supply a stimulation current which stepwise increases or decreases, to the electrode section, and being configured to obtain a sensitivity threshold that is a stimulation current from which the subject senses the electrical stimulation, from a situation of response to each stepwise supply, wherein in a case where a stimulation current which stepwise increases is to be supplied to the electrode section, the controlling section stepwise increases the stimulation current according to a predetermined increment, and, wherein in a case where a stimulation current which stepwise decreases is to be supplied to the electrode section, the controlling section stepwise decreases the stimulation current according to a predetermined decrement, wherein the controlling section is configured to perform a session process in which the supply of the stimulation current to the electrode section is repeated until a response is not confirmed, and obtains a minimum current value that is a minimum stimulation current at which the response can be confirmed, and, wherein in a case where a range where minimum current values that are obtained in sessions correlate with one another is set as a predetermined range of an effective current, and a number of sessions that are required for obtaining the sensitivity threshold is set as a number of valid sessions, when, within the predetermined range of the effective current, there are the minimum current values a number of which is equal to or larger than the predetermined number of valid sessions, the controlling section is configured to obtain the sensitivity threshold based on the minimum current values within the predetermined range of the effective current.
