Apparatus for the electrical stimulation of human tissue

摘要

An apparatus (22) for applying a therapeutic signal (31) to the scalp (32) of a subject (20) includes a first electrode (26) for massaging the scalp (32) and second electrode (30) in contact with the subject (20) and located remote from the first electrode (26). The therapeutic signal (31), passing between the first and second electrodes (26, 30) through the scalp (32), serves to loosen connective tissue and improve blood circulation in the scalp. The apparatus (22) includes digital waveform generators (54) for generating harmonically non-related resultant signals (96). The resultant signals (96) are combined to form the therapeutic signal (31) exhibiting a pseudorandom signal characteristic.
