Review
To date, a lack of published research studies exist that systematically analyze the factors involved with the progression of open-cup drinking in typically developing infants and toddlers. As a result, clinicians who are working with children that have delays in open-cup drinking development have a limited framework from which to base clinical decisions. The purpose of this review is to collate works from disparate and related fields to provide a brief review of the literature of pertinent sensorimotor and cognitive components necessary for successful open-cup drinking development.

Review
Bolus volume is an important modifier of the biomechanical events of the oropharyngeal swallow. The biomechanical events comprising a swallow can be divided into events associated with the reconfiguration of the pharynx into a swallow pathway and events associated with bolus transport from the oropharynx into the esophagus. Volume modification is achieved differently for the events of reconfiguration and propulsion. In the case of reconfiguration, a longer time is allocated to the process, as exemplified by sustained laryngeal elevation and hyoid excursion during larger volume swallows. On the other hand, in the case of bolus expulsion, volume accommodation is accomplished within the same period of time by utilizing increased vigor of expulsion. The result of deglutitive volume accommodation is a remarkably different fluoroscopic appearance of a small vs. a large volume swallow. The larger volume swallow seemingly takes longer and results in much more vigorous bolus expulsion than a small volume. However, this is more related to the bolus than the swallow.

Review
This review of the central nervous control systems for voice and swallowing has suggested that the traditional concepts of a separation between cortical and limbic and brain stem control should be refined and be more integrative. For voice production, a separation of the nonhuman vocalization system from the human learned voice production system has been posited based primarily on studies of nonhuman primates. However, recent humans studies of emotionally based vocalizations and human volitional voice production have shown more integration between these two systems than previously proposed. Recent human studies have shown that reflexive vocalization as well as learned voice production not involving speech involve a common integrative system. However, recent studies of nonhuman primates have provided evidence that some cortical activity vocalization and cortical changes occur with training during vocal behavior. For swallowing, evidence from the macaque and functional brain imaging in humans indicates that the control for the pharyngeal phase of swallowing is not primarily under brain stem mechanisms as previously proposed. Studies suggest that the initiation and patterning of swallowing for the pharyngeal phase is also under active cortical control for both spontaneous as well as volitional swallowing in awake humans and nonhuman primates.

OBJECTIVES/HYPOTHESIS
The pharyngeal phase of deglutition is considered to occur in a reflexive, preprogrammed fashion. Previous studies have determined a general sequence of events based on the mean timing of bolus transit and swallowing gestures. However, individual variability has not been studied. The purpose of the present study was to evaluate the amount of sequence variability that normally occurs during the oropharyngeal phase of deglutition.
STUDY DESIGN
Prospective analysis of conservative subjects.
METHODS
Dynamic swallow studies from 60 normal volunteers were evaluated, and event sequence variability was determined around two event sequences during swallowing of three bolus sizes.
RESULTS
There was found to be substantial variability in event sequences for all events analyzed. Variability was greater during a smaller bolus swallow.
CONCLUSIONS
The evaluation of variability within the study group of individuals reveals the complexity of the swallowing mechanism and underscores the importance of not relying on general guidelines in evaluating the coordination of swallowing gestures in a given individual with dysphagia complaints.

Review
The radiological study of the mechanism has helped to define the physiology of the oral and pharyngeal phase of deglutition. Being a dynamic examination, it is part of the work-up in swallowing disorders, such as cervical dysphagia and inhalation episodes. Among the various techniques available, videofluoroscopy remains the examination of choice.

Review
Videofluoroscopy and videoendoscopy dramatically changed the evaluation and management of swallowing disorders. Later advancements in techniques for the instrumental evaluation of swallowing were limited by technique and positioning. The advent of 320-row area detector CT solved previous challenges and allowed for the study of swallowing physiology and dysphagia in greater detail. In this summary, we describe the history and evolution of CT technology and describe research and clinical applications for the evaluation of swallowing physiology and pathophysiology.
