Resolution of Spasmodic Dysphonia (Focal Laryngeal Dystonia) via Chiropractic Manipulative Management
J Manipulative Physiol Ther 1991 (Jul); 14 (6): 376–378
This paper discusses the case of a 46-yr-old male suffering from spasmodic dysphonia, a chronic disorder involving hyperadduction of the vocal mechanism and resultant vocal arrest. Attention is paid to the neural innervation of the intrinsic laryngeal musculature and postulated mechanisms of irritation which may be amenable to chiropractic manipulative therapy. The type of spinal adjustment and treatment schedule are discussed.
Muscle Tension Dysphonia and Spasmodic Dysphonia:
The Role of Manual Laryngeal Tension Reduction in Diagnosis and Management
Ann Otol Rhinol Laryngol 1996 (Nov); 105 (11): 851–856
Excessive activity of the extralaryngeal muscles affects laryngeal function and contributes to a spectrum of interrelated symptoms and syndromes including muscle tension dysphonia and spasmodic dysphonia. Recognition of the role of extralaryngeal tension is helpful in ensuring proper diagnosis and selection of appropriate treatment. This report demonstrates the application of manual laryngeal musculoskeletal tension reduction techniques in the diagnosis and management of laryngeal hyperfunction syndromes. The manual technique consists of focal palpation to determine 1) extent of laryngeal elevation, 2) focal tenderness, 3) voice effect of applying downward pressure over the superior border of the thyroid lamina, and 4) extent of sustained voice improvement following circum-laryngeal massage. The clinical utility of this innovative approach is discussed.
