[Transcutaneous electrostimulation in the treatment of benign somatic chronic pain: evaluation of a new stimulator].

40 patients affected by chronic orthopaedic syndromes, outlasting 6 months, have been treated by transcutaneous electrical stimulation. Has beem employed a new commercial stimulator with these impulse parametres: 50 Hz, 0,2 msec of length, 30 mA. Rubber electrodes on trigger points or myalgic areas were used. Authors obtained the following results: in 14 patients any change, in 10 patients mild improvement but of short effect, in 16 patients a good and long term improvment. skin lesions were not observed during electrical stimulation treatment.
