The technique of alopecia areata treatment with sinusoidal modulated currents is simple and may be used on an outpatient basis. The Amplipul's-4 apparatus sensors have been placed in the cervical sympathetic node area. The current parameters have been as follows: P-1, III PP for 2-3 min, then IV PP for 2-3 min, modulation frequency 100-80 Hz and depth 50-75%, the pulse length within 2-4 sec provided the current strength is sufficient. The course of treatment included 10-12 sessions. Parallel with this physiotherapeutic modality, the patients were administered FiBS (a liman mud biogenic stimulant), vitamins B1 and B6, and andecalin. Clinical effect has been achieved in 46 of the 53 patients with a short duration of the disease. The authors' observations confirm the contribution of the sympathetic nervous system function to the genesis of alopecia.
