“…Langmore and Lehman (1994, p. 35), in fact, found dissociations between the two kinds of measures, noting the following about the expected link between the physiological and acoustic/perceptual measures: ''If this were true, maximum speech rate for repeated /puh/ would have correlated most highly with lip maximum rate of repeated contractions, and repeated /tuh/ would have correlated most highly with tongue maximum rate. In fact, both of these speech rate measures were correlated most highly with jaw maximum rate'' (A similar dissociation between speech movements and oromotor, nonspeech movements was also reported by Schliesser (1982) for a group of adults with cerebral palsy). The final mixed result is in Solomon, Lorell, Robin, Rodnitzsky, and Luschei (1995), where scaled estimates of articulatory imprecision were not significantly correlated with either tongue strength or endurance (see the negative endurance result in Solomon, Robin, & Luschei, 2000) in a group of patients with Parkinson disease, but tongue strength was significantly correlated with a scaled estimate of speech defectiveness.…”

The primary objective of this position paper is to assess the theoretical and empirical support that exists for the Mayo Clinic view of motor speech disorders in general, and for oromotor, nonverbal tasks as a window to speech production processes in particular. Literature both in support of and against the Mayo clinic view and the associated use of oromotor, nonverbal tasks, is reviewed, along with literature from normal speech production and neurophysiology. This literature is organized and analysed to show that theoretical and experimental support for the Mayo view is weak at best, and that the frequent appeal to oromotor, nonverbal tasks is misguided. We conclude that studies of speech production in motor speech disorders, rather than oromotor nonverbal control or of neurological signs, is the correct approach for advancing the field.

“…Hence, it is known to be a routine procedure for evaluating oromotor skills of individuals with different speech disorders. Oral‐DDK measures have been used to study various motor speech disorders associated with Parkinson's disease (Karlsson & Hartelius 2019), amyotrophic lateral sclerosis (Langmore & Lehman 1994), and cerebral palsy (Schliesser 1982). These findings support the use of oral‐DDK for SLTs to discriminate between normal and disordered speech production and monitor disease progression.…”

Background: It is unclear whether oral diadochokinetic rate (oral-DDK) performance is affected by different languages within a multilingual country. Aims: This study investigated the effects of age, sex, and stimulus type (real word in L1, L2 vs. non-word) on oral-DDK rates among healthy Malaysian-Malay speakers in order to establish language-and age-sensitive norms. The second aim was to compared the nonword 'pataka' oral-DDK rates produced by Malaysian-Malay speakers on currently available normative data for Hebrew speakers and Malaysian-Mandarin speakers.Methods & Procedures: Oral-DDK performance of 90 participants (aged 20-77 years) using nonword ('pataka'), Malay real word ('patahkan'), and English real word ('buttercake') was audio recorded. The number of syllables produced in 8 seconds was calculated. Mixed analysis of variance (ANOVA) was conducted to examine the effects of stimulus type (nonword, Malay, and English real word), sex (male, female), age (younger, 20-40 years; middle, 41-60 years; older, ≥61 years), and their interactions on the oral-DDK rate. Data obtained were also compared with the raw data of Malaysian-Mandarin and Hebrew speakers from the previous studies. Outcomes & Results:A normative oral-DDK rate has been established for healthy Malaysian-Malay speakers. The oral-DDK rate was significantly affected by stimuli (p < 0.001). Malay real word showed the slowest rate, whereas there was no significant difference between English real word and nonword. The 1026

“…Comprehensive examinations have been performed in children with cerebral palsy and with developmental dyspraxia (Hixon & Hardy, 1964;Wit, Maassen, Gabreëls, & Thoonen, 1993;Wit, Maassen, Gabreëls, Thoonen, & Swart, 1994), in dysarthria after stroke (Kent, Duffy, Kent, Vorperian, & Thomas, 1999;Ziegler & Von Cramon, 1986), in adult dysarthrics with cerebral palsy (Schliesser, 1982;Platt, Andrews, Young, & Neilson, 1978) or with amyotrophic lateral sclerosis (Langmore & Lehman, 1994), and in patients with ataxic dysarthria (Tatsumi, Sasanumo, Hirose, & Kiritani, 1979;Portnoy & Aronson, 1982;Gentil, 1990a;Ziegler & Wessel, 1996) or with basal ganglia disorders (Kreul, 1972;Ludlow, Connor, & Bassich, 1987;Ackermann, Hertrich, & Hehr, 1995;Hefter, Arendt, Stremmel, & Freund, 1993). Maximum syllable repetition tasks have also been used to measure the natural course of neuromotor speech disorders (Kent et al, 1991;Nishio & Niimi, 2000) or to monitor therapeutic modulations of these disorders (Wessel et al, 1995).…”

“…In particular, it is not sufficiently clear to what extent speech impairment and dysdiadochokinesis covary, although a significant correlation was found in most reports. In a study of 15 adults with cerebral palsy Schliesser (1982) found a relationship between ratings of dysarthric severity and DDK rates, with correlation coefficients ranging between .58 and .73. Platt et al (1978) observed a significant correlation of r ϭ .76 between DDK rate and single word intelligibility in 65 adult patients with cerebral palsy.…”
