Objectives: Speech diadochokinesis (DDK) is defined as the ability to produce repetitive and fast oral movements. The aim of this study is to compare the DDK rate between young and elderly Persian adults. Methods: In this study, 244 normal adults (122 males and 122 females) were divided two groups: young people (aged 20-49) and elderly people(aged 50-69). Diadochokinesis was performed based on...

PURPOSE The supracricoid laryngectomies (SCLs) are conservative surgical techniques for the treatment of selected laryngeal carcinomas. The advantage of SCL is that a permanent tracheostoma is not required, thus, maintaining the principal laryngeal functions. The aim of the study is to report objective, subjective, and self-assessment long-term results of voice and swallowing in a large group o...

UNLABELLED Oro-facial and speech motor control disorders represent a variety of speech and language pathologies. Early identification of such problems is important and carries clinical implications. A common and simple tool for gauging the presence and severity of speech motor control impairments is oral-diadochokinesis (oral-DDK). Surprisingly, norms for adult performance are missing from the ...

UNLABELLED The evaluation of oral and vocal fold diadochokinesis (DDK) in individuals with voice disorders may contribute to the understanding of factors that affect the balanced vocal production. Scientific studies that make use of this assessment tool support the knowledge advance of this area, reflecting the development of more appropriate therapeutic planning. OBJECTIVE To compare the res...

Objective: Oral diadochokinesis (ODK) has been shown to be associated with oral frailty. In this study, we investigate the relationship between physical function, swallowing nutritional evaluation, and each syllable of ODK. Methods: The subjects are 26 elderly people living in an area where they can walk. ODK, tongue pressure, modified water test, EAT-10, grip strength, MNA-SF, skeletal muscle ...

Dysarthria is present in 23 51% of multiple sclerosis (MS) patients, and the perceived characteristics of dysarthria have been shown to predict quality of life in these individuals. Tests of maximum performance such as oral diadochokinesis and Sequential Motion Rates (SMRs) are used in many neurology clinics and are considered to be sensitive indices of dysarthria. This large scale study invest...

Clinical dysarthria test scores on lip function and tongue function were compared for 77 dysarthric as well as non-dysarthric subjects with multiple sclerosis (MS) and 15 control subjects. Results show that tongue function was significantly more severely affected than lip function in individuals with MS. Furthermore, tongue function, but not lip function, was significantly more severely affecte...

The hypokinetic dysarthria observed in Parkinson's disease (PD) affects the range, speed, and accuracy of articulatory gestures in patients, reducing the perceived quality of speech acoustic output in continuous speech. Deep brain stimulation (DBS) of the subthalamic nucleus (STN-DBS) and of the caudal zona incerta (cZi-DBS) are current surgical treatment options for PD. This study aimed at inv...
