Abstract
The apparatus for electrical stimulation is more particularly adapted for the treatment of scoliosis and comprises an electrical circuit which delivers individual pulses having a duration of about 1 ms, an amplitude of about 150 V, a constant current intensity of about 75 mA and a frequency of 100 Hz as well as series of pulses with rising amplitude and a ramp up phase of about 2 s, followed by holding phase of about 2 s and a time off between two series of pulses of about 10 s. The apparatus further comprises three channels, whereby the first channel is applied on the side of the curvature, the second channel on the side of the counter curvature and the third channel on the abdominal musculature, whereby all channels are fed simultaneously.
