✦ Synopsis
In a project on the mapping of body surface potentials evoked by implanted spinal cord stimulators and transcutaneous electrostimulators, a simple device was developedfor use in polyclinicalpracticefor easy checking of the function of these stimulators. The device is an electrical stethoscope and consists of an instrumentation ampl$er, bandpass filter, a distortion circuit and a headphone. In uivo measurements demonstrate the generation of an amplitude-dependent tone by the distortion circuit. The apparatus is in many aspects
similar to a stethoscope: simple to understand and a practical tool for a fast Go/No-Go test. The device can be optionally connected with a PC and enables body surface mapping documentation within a few minutes.
