Device for examining of electrical stimulated muscles just as method of examining of muscle fiber

摘要

The device (UA) measures the power of muscles or muscle groups stimulated by electric pulses (S). The signals of the mechanical response of the muscles are converted into electric signals. Probes lie on the muscle to be detected, on the exterior of the skin and convey the electric signals to at least one display device. The measurement value convertor (M) is formed such that the cycle of its electric output signals is proportional to the differential of the cycle of its mechanical input signals. The convertor is formed as an immersion coil (S) with a movable permanent magnet (P). Either the magnet or the coil acts as a probe to pick up the mechanical signals of the muscle. The coil with the current induced by the movement of the magnet acts as an output signal generator. The electric pulse of the device comprises several partial pulses.
