Bite blocks are used to stabilize the jaw and to isolate tongue and lip movements from that of the mandible during speech and nonspeech activities. Ten normally speaking young adults produced sentences with an unconstrained jaw and with unilateral placement of 2-mm and 5-mm bite blocks. Six listeners rated sentences spoken without either bite block as the most natural sounding. Spectral characteristics of /s/, /ʃ/ and /t/ (sibilant frication and stop bursts) differed significantly with than without bite blocks, such that mean spectral energy decreased, and variation and skew of spectral energy increased...

The phonetic characteristics of words are influenced by lexical characteristics, including word frequency and phonological neighborhood density (Baese-Berke & Goldrick, 2009; Wright, 2004). In our previous research, we replicated this effect with neurologically healthy young adults (Munson & Solomon, 2004). In research with the same set of participants, we showed that speech sounded less natural when produced with bite blocks than with an unconstrained jaw (Solomon, Makashay, & Munson, 2016). The current study combined these concepts to examine whether a bite-block perturbation exaggerated or reduced the effects of lexical factors on normal speech...

In clinical speech-language pathology practice, tongue force is usually evaluated qualitatively. Perception and practical experience are used to classify this force. The Biomechanical Engineering Group from the Federal University of Minas Gerais developed an instrument to quantify tongue force. The purposes of this study were to quantify maximum tongue protrusion force in Brazilian subjects with normal tongue strength and to compare force values between gender groups. In total, 105 subjects, 43 men and 62 women, aged from 18 to 29 years, with normal tongue strength according to qualitative evaluation, underwent quantitative evaluation by using the instrument...

The origins of Orofacial Myofunctional Therapy began in the early 1960's by orthodontists who recognized the importance of functional nasal breathing, proper swallowing, and more ideal oral rest postures. Re-patterning these functions through myofunctional therapy assisted with better orthodontic outcomes and improved stability. Experts in orofacial myology have concluded that improper oral rest postures and tongue thrusting may be the result of hypertrophy of the lymphatic tissues in the upper airway. Orthodontists are aware of the deleterious effects these habits have on the developing face and dentition...

UNLABELLED: Masticatory performance is determined not only through the speed of mastication, or by the quantity of food ingested; it also depends on the structures and functional integration of the stomatognathic system (SS). OBJECTIVES: This study investigated differences in the SS and orofacial motricity between obese and normal--weight women. METHOD: A total of 18 obese women, with an average age of 28 ± 7.3 years and an average body mass index (BMI) of 37...

BACKGROUND: Lingual, labial and buccal weakness (LLBW) is a widespread consequence of several neurological insults. LLBW impact on oral motor functions such as speech production and swallowing is well documented in the literature. Therefore, it is important for the speech-language pathologists to have access to evidence-based approaches for treatment. Thus, it is imperative that the speech-language pathology field search for effective treatment approaches and explore new treatment modalities that can improve therapy outcomes...

UNLABELLED: Head posture has been related to pharyngeal space, especially in the syndrome of obstructive sleep apnea (OSA) in adults. However no studies were found that evaluated the possible correlation between head posture and pharyngeal airway space measured in children with atypical swallowing. The purpose of this study was to evaluate the possible correction between head posture and the measurement of pharyngeal space on radiographs of children who were in the period of mixed dentition who demonstrated atypical swallowing and in children with normal deglutition...

The objective of this study was to describe the oral phase of swallowing in individuals with dental malocclusion and to generate data that would contribute to the rehabilitation of those patients. The study was based on the evaluation of the swallowing system through videofluoroscopy on thirty-four children of both genders, aged eight to twelve years old who present with Angle Class II and III dental malocclusions. Thirteen children of similar age and gender presenting normal dental occlusion formed the control group...

Orofacial myologists are frequently called upon to address retained oral habit concerns. During this process, current I.A.O.M. recommended treatment includes addressing tongue, lip, and jaw rest posture concerns. Following digit sucking remediation, we may also be called upon to address these rest posture issues, and tongue thrust more aggressively together. In this process, facial growth and development and jaw structure may coincidentally improve as a result of 'nature taking its course' by addressing both swallow AND rest posture...

The purpose of this study was to determine if electropalatography (EPG) would be a useful adjunct and feasible option for those conducting clinical assessments of individuals with suspected nonspeech orofacial myofunctional disorders (NSOMD). Three females (two adults, one child) were referred by their orthodontist for assessment of suspected NSOMD. Three adults and one child without NSOMD were recruited for the purpose of evaluating methodological construct, and to provide comparisons for participants with NSOMD...

As the angle is a weak region in the continuity of mandible, so it is more prone to fracture. It has been proven time and again that coronoid fracture results from a strong sudden contraction of temporalis. Muscular forces influence the remodeling of bones. Orofacial dystonia is a centrally mediated disease in which there is an uncontrolled spasmodic contraction of facial and masticatory muscles. This continuous force applied over a long period of time has the potential to unfavorably remodel or weaken bone...

Fine control of orofacial musculature is necessary to precisely accelerate and decelerate the articulators across exact distances for functional speech and coordinated swallows (Amerman & Parnell, 1990; Benjamin, 1997; Kent, Duffy, Slama, Kent, & Clift, 2001). Enhanced understanding of neural control for such movements could clarify the nature of and potential remediation for some dysarthrias and other orofacial myofunctional impairments. Numerous studies have measured orolingual force and accuracy during speech and nonspeech tasks, but have focused on young adults, maximum linguapalatal pressures, and upright positioning (O'Day, Frank, Montgomery, Nichols, & McDade, 2005; Solomon & Munson, 2004; Somodi, Robin, & Luschei, 1995; Youmans, Youmans, & Stierwalt, 2009)...

The purpose of the current investigation was to explore how intra-oral negative pressure and submental muscle activity vary across sips from straws varying in internal diameter and across conditions of low versus high effort. Healthy adults took discrete sips from four straws varying in internal diameter. Sips were performed under normal and high effort conditions. Submental surface electromyography (sEMG) and negative intra-oral pressure were recorded during sips. Significant main effects of straw condition were observed for negative intra-oral pressure...

An efficient lingual frenulum protocol with scores is presented. From a specific lingual frenulum evaluation used until 2004, a new protocol was designed. Ten speech language pathologists experienced in orofacial myology used the new protocol with different groups of subjects. 1235 subjects were evaluated during 3 years. From the experience of these ten speech language pathologists, the protocol was re-structured, and a scoring system was added. Absence of alteration (normal tongue and frenulum) was scored zero...
