Tongue strength: its relationship to tongue thrusting, open-bite, and articulatory proficiency.

Maximum protrusive tongue strength was measured for two experimental groups of 35 normal speaking children and 21 children with frontal lisping, anterior tongue thrusting during swallow, and open-bite malocclusion, and a control group of 85 children with normal speech and occlusion who did not thrust their tongues during swallow. No significant differences in tongue strength were found among these groups. The findings were interpreted to support the view that tongue strengthening exercises recommended by some authors for the correction of tongue thrusting or associated frontal lisping may be superfluous.

Tongue force in normals and in dysarthric patients with amyotrophic lateral sclerosis.

Tongue force, rate of syllable repetition, and judgments of articulatory defectiveness were measures obtained on 19 dysarthric adults with amyotrophic lateral sclerosis and on 125 normal adults. Anterior and lateral tongue forces were measured by means of a pressure transducer clasped between the teeth; the tongue forces were recorded on a pen-writing ECG apparatus. Audio-recorded syllable repetitions of /p lambda/, /t lambda/, and /k lambda/ also were transcribed on ECG paper and counted. Three listeners rated articulatory precision on a 7-point scale of severity. The normal males had significantly higher tongue forces than normal females; normal subjects had significantly higher tongue forces than dysarthric patients; and anterior tongue forces were significantly greater than lateral in normal and dysarthric patients. There was a high negative correlation between tongue force and severity of articulatory defect. Syllable repetitions were significantly slower in the dysarthric patients than in the normal patients, and a high negative correlation was obtained between syllabic rate and severity of articulatory defect.

Tongue strength Part I: Following total laryngectomy.

Surgical repositioning of the genioglossus muscle, as in total laryngectomy, may have an adverse effect on the protrusive strength of the tongue. To test this premise, anterior and lateral tongue strength measures were obtained from 10 laryngectomized and 15 normal subjects by means of a pressure transducer and recording device. The results indicated no significant difference between laryngectomized and normal subjects on tongue strength measures. Further, all laryngectomized subjects were judged to have good to excellent esophageal speech. It was concluded that laryngectomy does not adversely affect the major musculature concerned with protrusive tongue strength for proficient esophageal speakers.

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.

Tongue strength measurement in patients with amyotrophic lateral sclerosis: qualitative vs quantitative procedures.

Tongue weakness and articulatory imprecision have been found to be significantly related in patients with amyotrophic lateral sclerosis (ALS). To determine the strength of the tongue musculature, qualitative measurement techniques are routinely used during the neurologic examination. Recently, a quantitative measurement procedure was described and reported to have yielded important diagnostic and therapeutic implications for patients with ALS. This paper briefly compares and contrasts the applicability of qualitative versus quantitative procedures of tongue strength measurement, as well as different approaches to articulatory remediation for these patients.

Influence of lingual muscular strength on articulatory proficiency.

The purpose of this study was to examine the relationship between lingual muscular strength (LMS) and articulatory proficiency in 45 normal and 45 lisping speakers utilizing a Lingual Force Scale designed specifically for this investigation. Results revealed that lispers exhibited significantly reduced LMS as compared to their matched controls. No significant differences in LMS between males and females with lisped speech, or between normal speaking males and females were found to exist at 5 age levels. Significant positive correlations were noted between age and LMS in both groups of subjects. In light of these findings, it might be suggested that lisping should not be viewed always as a purely functional disorder of the speech musculature.

Progressive speech deterioration and dysphagia in amyotrophic lateral sclerosis: case report.

Amyotrophic lateral sclerosis (ALS) is a degenerative neurologic disease having both upper and lower motor neuron signs and symptoms. When the speech musculature is involved, a mixed dysarthria and dysphagia usually result. In a 49-year-old man with ALS, dysarthria and dysphagia progressed from mild to severe forms over 17 months. Eleven months after the patient first experienced symptoms, neurologic examination showed fasciculations of the extremities and tongue, limb weakness, and hyperreflexia of the limbs and velopharyngeal mechanism. Tongue strength was one-fourth that of normal. Lingual alternate motions rates for consonant-vowel syllables were also reduced. To enhance lingual strength and swallowing, a tongue-strengthening program was developed for use with articulation training; to augment velopharyngeal function, a palatal lift was fitted; and to increase extremity strength, physical therapy was initiated. Six months after the initial neurologic examination, medical and speech reevaluation showed progressive weakness of the body parts affected initially; continued decline in tongue strength and lingual alternate motion rate; hypoactive reflex activity, indicative of progressive involvement of the lower motor neuron system; and continued deterioration of articulation and phonation owing to the progressive nature of the disease.
