“…This finding highlights the potential limits of cortical control to override the swallowing motor plan, which is responsible for opening the UES [37,91]. This, however, may be true only in healthy participants with normal swallowing, thereby limited in their ability to modulate this already functional response [91].…”

“…Elaborating on the focus of Nativ-Zeltzer et al [ 88 ], Winiker et al [ 91 ] explored the potential for behavioural UES pressure adaption during swallowing in healthy adults. Participants in this study were asked to increase the period of pressure drop in the region of the UES (UES-Pdrop) without altering swallowing biomechanics [ 91 ]. Six healthy females aged between 23 and 68 years (mean age of 36 years) attended daily, 45-min sessions, for 2 weeks (10 days) [ 91 ].…”

“…Participants were initially familiarized with major landmarks and points of interest on the high-resolution manometry (HRM) contour plots. Subsequently, they were asked to self-explore methods to prolong the duration of UES opening through pressure manipulation at the UES itself, and avoid altering the overall swallowing pattern [ 91 ]. In total, 64 saliva swallows were performed each session, with regular breaks between.…”

“…In total, 64 saliva swallows were performed each session, with regular breaks between. Baseline and outcome measures were recorded during performance of natural swallows (e.g., five saliva and five cup-sip water) followed by manipulated swallows, whereby the participants were asked to increase the duration of pressure drop [ 91 ]. Initial assessment revealed no overall change in pharyngeal dynamics as measured by pharyngeal timing and pressure.…”

Over the past four decades, our understanding of swallowing neural control has expanded dramatically. However, until recently, advances in rehabilitation approaches for dysphagia have not kept pace, with a persistent focussing on strengthening peripheral muscle. This approach is no doubt very appropriate for some if not many of our patients. But what if the dysphagia is not due to muscles weakness? The purpose of this clinical manuscript is to reflect on where we have been, where we are now and perhaps where we need to go in terms of our understanding of swallowing motor control and rehabilitation of motor control impairments. This compilation is presented to clinicians in the hope that suggesting approaches “outside the box” will inspire clinicians to focus their attention “inside the box” to ultimately improve rehabilitation and long-term outcomes for patients with dysphagia.
