“…For example, one has voluntary control over when to start and stop chewing, but once the stereotyped pharyngeal all-or-none response is triggered, it cannot be interrupted or reversed [2]. Many components of oropharyngeal swallowing are believed to be controlled by brainstem central pattern generators [3,4], but some characteristics are cortically modulated [5][6][7][8]. Breakdown in any of the sensory or motor components of the oropharyngeal swallow can lead to inefficient and unsafe swallowing (dysphagia).…”

Any movement performed repeatedly will be executed with inter-trial variability. Oropharyngeal swallowing is a complex sensorimotor action, and swallow-to-swallow variability can have consequences that impact swallowing safety. Our aim was to determine an appropriate method to measure swallowing pressure waveform variability. An ideal variability metric must be sensitive to known deviations in waveform amplitude, duration, and overall shape, without being biased by waveforms that have both positive and sub-atmospheric pressure profiles. Through systematic analysis of model waveforms, we found a coefficient of variability (CV) parameter on waveforms adjusted such that the overall mean was 0 to be best suited for swallowing pressure variability analysis. We then investigated pharyngeal swallowing pressure variability using high-resolution manometry data from healthy individuals to assess impacts of waveform alignment, pharyngeal region, and number of swallows investigated. The alignment that resulted in the lowest overall swallowing pressure variability was when the superior-most sensor in the upper esophageal sphincter (UES) reached half its maximum pressure. Pressures in the tongue base region of the pharynx were least variable and pressures in the hypopharynx region were most variable. Sets of 3-10 consecutive swallows had no overall difference in variability, but sets of two swallows resulted in significantly less variability than the other dataset sizes. This study identified variability in swallowing pressure waveform shape throughout the pharynx in healthy adults; we discuss implications for swallowing motor control.

“…A chronological analysis of the presented studies, observed that initially the concern was the confirmation of cortical activation mechanisms for swallowing Therefore, procedures such as saliva (1,3,5,7,(16)(17)(18)(19)(20)22,23,26,(29)(30)(31)(32) , water (5,11,12,17,(24)(25)(26)28,29,31) , barium (5,26,29,31) swallowing were performed, comparing swallow and not swallow (1,7,14,27) . Later on, studies began to analyze differences in the cortical areas, responsible for each motor phase, differentiating the role of the structures involved.…”

“…In an attempt to assess the representativeness of sensory--motor organs, the authors proposed an examination of cortical responses to movements used in rehabilitation procedures, such as orofacial exercises (1,14,21,27) and maneuvers used in rehabilitation (18) . Even on population with dysphagia, they used swallowing of different types of food, such as water (5,(29)(30)(31) , barium (5,29,31) and saliva (5,(29)(30)(31)(32) .…”

In studies examining the food swallowing, its ingestion was the track for the patient to swallow, i.e., the absence of formal statement was a major factor, differentiating it from studies with other types of tasks.…”

Functional MRI of swallowing: From neurophysiology to neuroplasticity

2011

View full text Add to dashboard Cite

Swallowing is a complex neurogenic sensorimotor process involving all levels of the neuraxis and a vast number of muscles and anatomic structures. Disruption of any of these anatomic or functional components can lead to swallowing disorders (also known as dysphagia). Understanding the neural pathways that govern swallowing is necessary in diagnosing and treating patients with dysphagia. Functional MRI (fMRI) is a prevalent and effective neuroimaging method that has been used to study the complex neurophysiologic control of swallowing in vivo. This article presents a summary of the research studies that have used fMRI to study the neural control of swallowing in normal subjects and dysphagic patients, and to investigate the effects of swallowing treatments on neuroplasticity. Methodologic challenges and caveats are discussed, and a case study of a pre‐posttreatment paradigm is presented to highlight potential future directions of fMRI applications in swallowing research and clinical practice. © 2011 Wiley Periodicals, Inc.
