Peroneal Electric Transcutaneous NeuroModulation (eTNM^®): A Novel Method for the Treatment of the Overactive Bladder

Table 2

The volt-ampere characteristics of the impulses generated by the URIS^® and UROstim2^® generators when the human volunteer was included in the circuit as a load.

Device	UROstim2^®	UROstim2^®	URIS^®	URIS^®
Electrodes	URIS^®	URIS^®	URIS^®	URIS^®
Impulse width (ms)	0.2	0.4	0.2	2.0
Voltage (V)	30.3	42.0	18.9	15.0
Current (mA)	10.0	9.6	11.9	4.3
Energy (mJ)	0.066	0.161	0.044	0.130
Charge (µC)	2.0	3.8	2.4	8.6

The voltage and current are presented as RMS values. The data demonstrate that extending the impulse width using the UROstim2^® device led to a significant increase in voltage, while extending the impulse width using the URIS^® device led to a reduction of the voltage and current required for effective nerve stimulation. This results in a significant reduction in exposure to the patient.
