Recent clinical data indicate that internal cueing mechanisms required for the triggering of movement sequences are impaired in Parkinson's disease (PD). Nevertheless, most PD subjects produce maximal syllable repetition rates similar to those observed in healthy control individuals during oral diadochokinesis tasks. There is some evidence that tremor oscillations may pace repetitive movements ...

The relationship between diadochokinetic rates and the degree of articulation impairment, measured as number of articulation errors on a test, was investigated. Sixand eight-year old children with articulation impairment demonstrated reduced diadochokinetic rates which appeared to improve with age. The larger the number of articulation errors, the slower the rates on both verbal and non-verbal ...

Background: The mel-frequency cepstral coefficients (MFCC) are relied for their capability to identify pathological speech. The literature suggests that triangular mel-filters that are used in the MFCC calculation provide an approximation of the human auditory perception. This approximation allows quantifying the clinician’s perception of the intelligibility of the patient’s speech that allows ...

Purpose To verify and compare the effect of transcutaneous electrical nerve stimulation (TENS) and laryngeal manual therapy (LMT) on laryngeal diadochokinesis (DDK) of dysphonic women. Methods Twenty women with bilateral vocal nodules participated and were equally divided into: LMT Group - LMT application; TENS Group - TENS application; both groups received 12 sessions of treatment, twice a w...

OBJECTIVES The purpose of the study was to acoustically compare the performance of children who do and do not stutter on diadochokinesis tasks in terms of syllable duration, syllable periods, and peak intensity. METHODS In this case-control study, acoustical analyses were performed on 26 children who stutter and 20 aged-matched normally fluent children (both groups stratified into preschooler...

The phonoarticulatory diadochokinesis test has been recommended to evaluate neurological disorders. It is a speech task that consists of the ability to repeat at high speed a segment of speech. The purpose of this research is to analyze the diadochokinesia rate of adults from two distinct age groups. 23 young adults and 23 elderly people, both sexes participated in this study. Each participant ...

Repetitive articulatory rate or Oral Diadochokinesis (oral-DDK) shows a guideline for appraisal and diagnosis of subjects with oral-motor disorder. Traditionally, meaningless words repetition has been utilized in this task and preschool children have challenges with them. Therefore, we aimed to determine some meaningful words in order to test oral-DDK in Persian speaking preschool children. Par...
