TLDR
Oral diadochokinesis deterioration is significantly associated with oral phase prolongation for initial swallowing of solid food in older adults.Abstract:
Background: Prolongation of bolus forming complicates ingestion, in particular in older adults. Objectives: The purpose of this study is to examine which oral functions are associated with prolongation of the oral phase of forming a bolus until swallowing in older adults. Design: Cross-sectional study. Setting: three nursing homes in Kitakyushu, Japan from August 2017 to October 2018. Participants: 39 adults >60-years. Measurements: Number of functional teeth, chewing ability, swallowing ability, tongue and cheek pressure, saliva flow rate, oral diadochokinesis, global cognitive function, and body mass index, were examined. Time of oral phase until the first swallowing of solid food was measured as the outcome of the study using video, and audio recording of the swallowing sound by a throat microphone, with the cutoff point designated at 30 s. Based on the oral phase, participants were divided in two groups: normal and prolonged. Results: The 39 enrolled participants had a median age of 87 years, 17.3% were men, and 48.7% had prolonged oral phase. In the prolonged group, the swallowing ability, saliva flow rate, tongue and cheek pressure, and oral diadochokinesis were significantly lower than in the normal group. Binomial logistic regression analysis revealed that oral phase prolongation was associated with oral diadochokinesis (odds ratio 0.81, 95% confidence interval 0.67–0.98) after adjusting for potential covariates. Conclusion: Oral diadochokinesis deterioration is significantly associated with oral phase prolongation for initial swallowing of solid food in older adults.read more

TL;DR: In this article, 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.

Food Transport and Bolus Formation during Complete Feeding Sequences on Foods of Different Initial Consistency
TL;DR: A new model for bolus formation and deglutition is proposed because there was no predictable tongue–palate contact at any time in the sequence of complete feeding sequences on soft and hard foods.

TL;DR: The objective of this review is to provide an overview of the variations of the measured masticatory variables that occur when mastication adapts to changes in characteristics of the individual or the food.

TL;DR: If sensory discrimination in the area innervated by the superior laryngeal nerve diminishes with increasing age is determined by applying a previously described new device and technique that utilizes brief air pulse stimulation of the anterior wall of the pyriform sinus, sensory discrimination can be reliably determined.

Task-related factors in oral motor control: speech and oral diadochokinesis in dysarthria and apraxia of speech.
TL;DR: Overall, dysdiadochokinesis was correlated with the degree of speech impairment, but there was a strong interaction between task type and motor speech syndrome, which affected DDK to a relatively greater extent than sentence production.
