Tongue strength. Part II: in artificial alaryngeal speech.
Tongue strength does not appear to be reduced in proficient esophageal speakers. However, no data exist on tongue strength for laryngectomized subjects who have not developed esophageal speech. Anterior and lateral tongue strength measures were obtained from 13 laryngectomized subjects who used an artificial larynx and 15 normal subjects by means of a pressure transducer and recording device. The results indicated that laryngectomized subjects had significantly weaker tongues in two of three directions measured. It was concluded that laryngectomy may affect tongue strength, but that the method of alaryngeal speech utilized postoperatively influences the return to normal.
