Diadochokinetic Rates

A procedure for measurement of the lingual frenulum in relation to the dimensions of the anterior, inferior segment of the tongue is described and its reliability established. The procedure was validated through physiological studies including speech articulation and oral motor coordination in diadochokinetic movements. Forty subjects were selected from a pool of 210 11–12 year old children and separated into two groups of twenty subjects on the basis of relative length of the lingual frenulum. Significant differences were found between these two groups both in speech articulation errors and in diadochokinetic rates of movement. Findings are discussed with respect to reliability and validity of the procedure. The findings are particularly pertinent to the clinical entity called congenital inferior ankyloglossia or “tongue-tie.”

The purpose of this investigation was to determine the relationships among frontal lisping, protrusive lingual force, and lingual diadochokinetic rates when subjects are grouped according to severity of lisping. Results revealed that when compared to normal speaking counterparts: (1) lispers in each severity subgroup exhibited significantly weaker protrusive lingual forces and that the significance of such differences increased with the severity of lisping; and (2) all but the moderately severe lispers displayed significantly slower lingual diadochokinetic rates. These findings suggest that clustering lispers into homogeneous severity subgroups before examining the relationships between their misarticulations and the lingual factors studied may offer important information regarding the diagnosis, treatment, and prognosis of their articulatory problems.

Lateral Sclerosis

The purpose of this study was to delineate some of the physiological deficits in the orofacial musculature of patients with dysarthria associated with amyotrophic lateral sclerosis (ALS) and to relate the physiologic deficits to perceived severity of dysarthria. Strain gauge force transducers placed on the lower lip, jaw, and tongue tip were used to measure maximum strength and maximum rate of repeated contractions. Diadochokinetic rates for repeated /p/ and /t/ were also determined. Fourteen ALS patients and 15 normal subjects were tested. It was found that the ALS patients with dysarthria were impaired in all tasks compared to the normal subjects, and that some measures revealed impairment even in those ALS patients who were not yet dysarthric. Bulbar ALS patients were generally more severely affected than the corticobulbar or spinal ALS patients, and the tongue was generally the most affected structure in all ALS groups. Perceived severity of dysarthria was more highly correlated with the measures of repeated contraction rate than with the measures of strength, suggesting that more severe dysarthria may be largely due to slower movement of the orofacial structures until substantial muscle strength has been lost.

Normal Speaking

This study examines protrusive lingual force and lingual diadochokinetic rates in normal and frontal-lisping speakers. Force measurements were obtained using an instrument designed for this investigation. Results revealed that normal-speaking children scored significantly higher on lingual force and diadochokinetic rate measurements. These findings challenge the notion that lisping is purely a functional articulatory disorder. Explanations for diagnosis and management are discussed.

Diadochokinetic Rates

One hundred thirty-three rural second graders were evaluated for diadochokinetic abilities and myofunctional variables. Single-syllable diadochokinetic rates were significantly correlated with open-mouth resting postures. Slow trisyllable diadochokinetic rates were significantly correlated with a dentalized resting tongue posture and dentalized swallow patterns. The implications of these relationships are discussed.

Administration Protocol

Assessments of oral-diadochokinetic rates are commonly performed to evaluate oral-motor skills. However, the appropriate administration protocol is not defined, and varies across therapists, clinics and laboratories. In three experiments and an auxiliary one, this study analyzes the effects of brief (motor) practice and visual feedback on the performance of 98 younger (20–40 years old) and 78 older adults (over 65) with the sequential motion rate (SMR) version. Overall rates were significantly faster for younger over older adults. Irrespective of age-group, averaged performance was significantly better on the second round, but the third round was found to be superfluous, across experiments and age-groups. Visual feedback (using a mirror) was found to be detrimental for younger adults, eliminating the advantage reaped from a practice round. For older adults, visual feedback did not alter the effect of a practice round. Sensory (visual) degradation is presented as a possible source for this age-related difference. We discuss these findings and suggest an administration protocol for younger and older adults with the SMR version, including a total of two rounds and no visual feedback.
