A comprehensive clinical guide to Laryngeal Electromyography (LEMG) for the diagnosis, treatment, and prognosis of voice and swallowing disorders

Principles and Practices of Laryngeal Electromyography combines electrophysiological theory with clinical practice to provide an authoritative yet accessible overview of Laryngeal Electromyography (LEMG). This essential resource equips clinicians with the scientific foundation needed to diagnose, treat, and determine prognosis for laryngeal immobility—including organic neuromuscular paralysis and cricoarytenoid joint abnormalities—as well as swallowing disorders, spasmodic dysphonia, and other laryngeal neuromuscular pathologies.

Featuring over 180 original clinical illustrations and 18 detailed case studies, this book bridges the gap between LEMG fundamentals and practical clinical applications, making this specialized technique more accessible to practitioners.

Principles and Practices of Laryngeal Electromyography covers:

• Applied anatomy and physiology of LEMG, including recorder and electrode selection, needle-electrode electromyography techniques, and evaluation parameters.
• Basic LEMG principles and operation, the laryngeal nerve conduction testing, and specialized electrophysiological tests, including repetitive nerve stimulation and single-fibre electromyography
• Clinical applications in vocal fold paralysis, including cases with lower cranial nerve injury and mechanical vocal fold immobility
• Neuromuscular disorders affecting the larynx, including laryngeal myopathy, myasthenia gravis, spasmodic dysphonia, and functional dysphonia

Principles and Practices of Laryngeal Electromyography is an indispensable reference for otolaryngologists, laryngologists, neurologists, physiatrists, residents, and other healthcare professionals seeking to master LEMG techniques and improve patient outcomes in voice and swallowing disorders.
