Electromyographic study in spondylogenic monocorditis

Cover Page

Abstract


Aim. To reveal relation between neuromascular disorders of the larynx and cervical spine pathology and to assess extrinsic laryngeal muscular tension in digital format.

Methods. The article contains clinical experience of the survey of 130 patients, 110 of whom were included into the study group with diagnosed spondylogenic monocorditis, and 20 healthy subjects were included into control group. All patients underwent electromyographic study using the patented Kh.A. Alimetov аnd D.D. Jabarov’s technique with the use of 4-channel electromyograph Neuro-MEP (Neurosoft) with the frequency range from 5 Hz to 20 kHz. The used method of interference (global) electromyography allowed obtaining information on laryngeal muscular tension in norm and spondylogenic pathology.

Results. In patients with spondylogenic monocorditis, the upper and lower muscle group tension was increased approximately by 1.2 times on the affected side in contrast to the opposite side. The received results confirm clinical trial data - on the affected side the vocal fold is visually thinner than the opposite fold, lags behind it during phonation and has decreased tension, and the increased tension of anterior laryngeal muscles on the right or left side, revealed during examination and palpation of the larynx, indicates neuromuscular disorder in cervical osteochondrosis on the affected side and involvement of certain laryngeal regions in the process of myofixation.

Conclusion. Electromyographic study provides quantitative assessment of laryngeal muscular tension imbalance, allows to correctly prescribe treatment and to control it.
