The Role of Bolus Residue and Its Relation with Respiratory Problems in Children with Esophageal Atresia
AbstractBolus residue is significant risk factor for postswallow aspiration. A retrospective study was performed to evaluate the role of bolus residue and its relation with respiratory problems in children with esophageal atresia. Children were evaluated for demographic features, type of esophageal atresia, associated anomalies, and respiratory problems. The videofluoroscopic swallowing evaluation (VFSE) was performed, and scored by using the penetration aspiration scale (PAS), bolus residual score (BRS) and normalized residual ratio scale (NRRS). Children with and without respiratory problems were also compared in terms o...

Impact of Quantitative Videofluoroscopic Swallowing Measures on Clinical Interpretation and Recommendations by Speech-Language Pathologists
This study explores agreement between traditional observational analysis and quantitative analysis, and the impact of analytical approaches on subsequent diagnosis and recommendations. One hundred adults referred for VFSSs with swallowing concerns were administered a standardised VFSS protocol. All VFSSs were analysed using three approaches: (1) a traditional observational analysis typically used by treating speech-language pathologists (SLPs), (2) quantitative analysis by two independent raters, and (3) binary subjective analysis by 11 independent raters. Three metrics were focussed on; pharyngeal constriction (PC), hyoid...

Surface Electromyography for Evaluating the Effect of Aging on the Coordination of Swallowing Muscles
This study evaluated the temporal events observed by sEMG to clarify how aging affects the coordination among the masticatory and suprahyoid muscles. We recruited elderly individuals (over 65  years old) who denied dysphagia. The sEMG activities of anterior temporalis, masseter, and suprahyoid muscles were recorded during 3, 15, and 30 ml water swallowing tests (WST). We calculated the time interval between anterior temporalis and suprahyoid peak activity (T-SH interval) and masseter a nd suprahyoid peak activity (M-SH interval) and analyzed their correlation with age. The subjects who could and could not swallow 30 ml ...

Defining Normal Sequential Swallowing Biomechanics
This study investigated sequential swallowing biomechanics in healthy adults. Archival normative videofluoroscopic swallow studies were analyzed for hyolaryngeal complex (HLC) patterning and biomechanical measures from the first 2 swallows of a 90-mL thin liquid sequential swallow task. The effects of age, sex, HLC type, and swallow order were explored. Eighty-eight participants were included in the primary analyses as they performed sequential swallows. HLC Type I (airway opens, epiglottis approaches baseline) and Type II (airway remains closed, epiglottis remains in verted) most commonly occurred (47% each), followed by ...

Electrokinesiographic Study of Oropharyngeal Swallowing in Neurogenic Dysphagia
AbstractElectrokinesiographic study of swallowing (EKSS) can be useful for the assessment of patients with suspected or overt neurogenic dysphagia. EKSS consists of multichannel recording of the electromyographic (EMG) activity of the suprahyoid/submental muscle complex (SHEMG), the EMG activity of the cricopharyngeal muscle (CPEMG), and the laryngopharyngeal mechanogram (LPM). The LPM is an expression of the mechanical changes that the laryngopharyngeal structures undergo during the pharyngeal phase of swallowing. This method allows detailed evaluation of the magnitude, duration and temporal relations of the different eve...
