Dysphagia is a symptom, commonly found in healthcare residents and the elderly, may lead to undernutrition and negative effects on quality of life. Providing special food products that cannot only be swallowed by patients but also meet nutritional requirements is a challenge for food rheologists and healthcare staff. The purpose of this paper was to review the literature on rheological aspects of dysphagia-oriented products. Also, some suggestions were proposed for better exploitation of rheological data in the field of dysphagia-rheology.

“…The superior longitudinal fasciculus, connecting the anterior (Broca's area) and posterior (Wenicke's area) language areas, is displayed in yellow colour in Figure 9. A number of descriptive studies indicate that a mature pattern of mastication is characterized by the emergence of a highly coordinated rotary motion of the jaw which is readily established during the first 24-30 months of life [27,28]. In this patient, however, jaw motions for chewing at the age of 5.5 years only consisted of roughly cyclic vertical mandibular elevations and depressions, constrained to the inferior-superior dimension of the maxillary-occlusional plane.…”

“…In this patient, however, jaw motions for chewing at the age of 5.5 years only consisted of roughly cyclic vertical mandibular elevations and depressions, constrained to the inferior-superior dimension of the maxillary-occlusional plane. This primitive chewing pattern is typically found in children of about six months of age in the course of normal mastication development [28]. Despite intensive oral-motor and feeding therapy the next stage in the sequence of early chewing development, i.e.…”

Mastication Dyspraxia: A Neurodevelopmental Disorder Reflecting Disruption of the Cerebellocerebral Network Involved in Planned Actions

This is the accepted version of the paper.This version of the publication may differ from the final published version. Permanent repository link AbstractThis paper reports longitudinal clinical, neurocognitive and neuroradiological findings in an adolescent patient with non-progressive motor and cognitive disturbances consistent with a diagnosis of developmental coordination disorder (DCD). In addition to prototypical DCD, development of mastication was severely impaired while no evidence of swallowing apraxia, dysphagia, sensorimotor disturbances, abnormal tone or impaired general cognition were found. He suffered from bronchopulmonary dysplasia and was ventilated as newborn for 1.5 months. At the age of three months a ventriculoperitoneal shunt was surgically installed because of obstructive hydrocephalus secondary to perinatal intraventricular bleeding. At the age of five, the patient's attempts to masticate were characterized by rough, effortful and laborious biting movements confined to the vertical plane. Solid food particles had a tendency to get struck in his mouth and there was constant spillage. As a substitute for mastication, he moved the unground food with his fingers in a lateral direction to the mandibular and maxillary vestibule to externally manipulate and squeeze the food between cheek and teeth with the palm of his hand. Once the food was sufficiently soft, the bolus was correctly transported by the tongue in posterior direction and normal deglutition took place. Repeat MRI during follow-up disclosed mild structural abnormalities as the sequellae of the perinatal intraventricular bleeding but this could not explain impaired mastication behaviour.Quantified Tc-99m-ECD SPECT, however, revealed decreased perfusion in the left cerebellar hemisphere, as well as in both inferior lateral frontal regions, both motor cortices and the right anterior and lateral temporal areas. Anatomoclinical findings in this patient with DCD not only indicate that the functional integrity of the cerebello-cerebral network is crucially important in the planning and execution of skilled actions, but also seem to show for the first time that mastication deficits may be of true apraxic origin. As a result it is hypothesized that "mastication dyspraxia" may have to be considered as a distinct nosological entity within the group of the developmental dyspraxias following a disruption of the cerebello-cerebral network involved in planned actions.

“…Briefly, the optical tracker is an equipment for motion capture, which can identify the three-dimensional positions of the optical sensors or markers using an ultra-red camera and the distance error is under 0.25 mm. 19,20 The optical marker was attached to the volunteers' chin area using a chin cap (Fig. 1), and the optical tracker and marker were set up to record the subjects' movements.…”

The objective of this study was to perform the quantitative three-dimensional analysis of the patients' movements at the different time points during the simulated acquisition of cephalometric radiographs. Fifty-three subjects (32 men, 21 women) were divided into four groups according to their age (Group 1: 9-12, Group 2: 13-19, Group 3: 20-25, and Group 4: 26-30 years old). The experiment (Exp) consisted in providing the subjects with three different kinds of verbal instructions as follows; Exp 1: they were simply instructed not to move, Exp 2: detailed instructions were provided, and Exp 3: they were specifically instructed to clench their molars. The amount of their movement during the 20 s of the cephalomatric X-ray exposure was measured using an optical marker and tracker. The maximum movement was analyzed three-dimensionally at 0.5, 2, 5, 10, 15, and 20 s. There was minimal vibrating movement every 0.3-0.5 s and relatively large movement every 3-5 s. The youngest group showed the largest amount of movement among the four age groups, and their movement was more significant in the up and down direction (pG0.05). There was no significant difference in the amount of movement according to the instructions. The longer exposure time showed the larger amount of the movement. Children can show the significant movements during X-ray taking, and the longer exposure time can also result in the larger movement during acquisition of cephalometric radiographs. Therefore, the shorter exposure time is recommended in order to improve image quality.
