METHOD OF TREATING PATIENTS WITH STABLE FUNCTIONAL VOICE DISORDERS Russian patent published in 2015 - IPC A61N1/32 A61H1/00 A61H23/02 

FIELD: medicine.

SUBSTANCE: method includes carrying out electrostimulation and exercises, aimed at the recovery of the laryngeal nervous-muscular apparatus work. The electrostimulation is realised by a current with a bipolar asymmetric pulse shape, with the frequency of 20-120 Hz, pulse duration of 0.2 ms, with 2 sec interval between the pulses. The time of exposure is 5-10 minutes. Seven pairs of electrodes, placed symmetrically, are used. The first and second pairs of electrodes are placed in the area of anterior and posterior bellies of the digastrics muscle on the left and on the right. The third and fourth pairs of electrodes are placed horizontally on the left and on the right in the area of upper and lower thirds of the lateral neck surface, crossing the sternocleidomastoid muscle. The fifth pair of electrodes is placed at the level of 3 and 6 cervical vertebrae in the area of the posterior neck surface on the left. The sixth pair of electrodes is placed at the level of 3 and 6 cervical vertebrae in the area of the posterior neck surface on the right. The seventh pair of electrodes is placed in the area of the middle third of the trapezius muscle on the left and on the right of the spine. After that the patient independently does a number of exercises. First he/she protrudes the tongue towards the teeth, then the tongue root is pulled back. Then he/she makes an inhalation and with the mouth closed, holds the nose wings for 1 s during one exhalation. After that, without opening the mouth, he/she makes an inhalation and holds the nose wings a single time for 5-7 seconds with their further opening during one exhalation. Then, he/she makes an inhalation, holds the nose wings and realises an exhalation through the mouth, shutting the lips one time for 1 second. The described exercise is repeated, increasing the duration of the lips shutting to 5-7 seconds. Each exercise is repeated by the patient 3-4 times running. While fulfilling the exercises the patient bends his/her head to the chest, pressing the chin to it. After performing the exercises, the shoulder girdle area is subjected to a vibrostimulation impact. The impact is realised with the frequency of 20-60 Hz, amplitude of 1.5 mm, at the rate of vibration frequency growth by 20% per 10 seconds. The time of the impact is 10-15 minutes. The course includes 8-12 daily procedures.

EFFECT: method increases the working range of the voice, recovers the phonation time due to the recovery of a contraction of the laryngeal muscles, normalises functions of the respiratory apparatus.
