Phonasthenia

a functional impairment of phonation.

Phonasthenia is caused by excessive or incorrect use of the voice and occurs primarily in singers, actors, and teachers. Unlike singers’ nodes (symmetrical nodules of connective tissue and epithelium located on the vocal cords), which are also accompanied by impairment of phonation, phonasthenia is not marked by visible organic changes in the vocal apparatus. In phonasthenia the voice becomes easily fatigued; it may crack or become hoarse and may sometimes disappear completely.

If sufficient rest is provided, voice function is usually restored without medical treatment. Physical therapy is used in case of persistent phonasthenia. The condition can be prevented by proper use of the voice.

fatigue

[fah-tēg´] 1. loss of the ability of a muscle to respond to stimuli.2. a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as an overwhelming sustained exhaustion and decreased capacity for physical and mental work at the usual level. Fatigue is a normal reaction to intense physical exertion, emotional strain, or lack of rest. When it is not relieved by rest, it may have a more serious origin; it may be a symptom of poor physical condition, a specific disease or oncoming disease, or severe emotional stress. Sometimes fatigue is psychological in origin. Tiredness and a loss of interest in one's work may actually result from boredom with the daily routine. If one is certain that there is nothing wrong physically, steps should be taken to vary the daily round, to seek new and more active ways to spend leisure time, perhaps to revive old interests that have been neglected.
