ABSTRACT
Functional voice disorder can be assumed if a thorough examination shows no mechanical impediment to the normal production of voice. Normal change of voice does not represent an etiologic factor of great importance according to Froschels and some voice trainers. If singing is taught during this time, it is not likely to injure the voice, provided the method is sound. Subjective symptoms in respect of voice may be absent; but patients often complain of various sensations, such as pains in the throat or neck, sometimes radiating towards the orbit or the ear. Their stamina is failing them, and the voice loses its timbre, volume, carrying power, and precision. The voice sounds muffled and may show all degrees of hoarseness down to complete aphony. The vocal chords are normal, unless there are signs of irritation, such as redness, swelling and loosening of the tissue owing to incessant exertion.
