PurposeThe aim of this study was to investigate improvements in swallowing function and physiology in a series of healthy older adults with radiographically confirmed dysphagia, following completion of an exercise-based swallowing intervention.Patients and methodsNine otherwise healthy older adults (six females, mean age =75.3, SD =5.3) had confirmed impairments in swallowing safety and/or efficiency on a modified barium swallow study. Each participant completed an 8-week swallowing treatment protocol including effortful swallows, Mendelsohn maneuvers, tongue-hold swallows, supraglottic swallows, Shaker exercises and effortful pitch glides. Treatment sessions were conducted once per week with additional daily home practice. Penetration–Aspiration Scale and the Modified Barium Swallowing Impairment Profile (MBSImP) were scored in a blind and randomized fashion to examine changes to swallowing function and physiology from baseline to post-treatment.ResultsThere were significant improvements in swallowing physiology as represented by improved oral and pharyngeal composite scores of the MBSImP. Specific components to demonstrate statistical improvement included initiation of the pharyngeal swallow, laryngeal elevation and pharyngeal residue. There was a nonsignificant reduction in median PAS scores.ConclusionSwallowing physiology can be improved using this standardized high-intensity exercise protocol in healthy adults with evidence of dysphagia. Future research is needed to examine the individual potential of each exercise in isolation and to determine ideal dose and frequency. Studies on various etiological groups are warranted.
The primary aim of this study was to investigate the immediate effects of partial versus complete head rotation and chin tuck on pharyngeal swallowing pressures and durations in the pharynx and UES of normal, healthy adults. Ten individuals (3 men and 7 women; age range 54-76 years) served as participants. Solid-state intraluminal manometry was performed with the participants in the upright position while performing swallows with the head in the normal position, head rotated (partial and complete), chin tucked, and chin down. A cervical range of motion (CROM) inclinometer was used to accurately measure the degree of head rotation and chin tuck. The CROM inclinometer has not been used before so this is the first study to our knowledge to quantify degree of head rotation and chin tuck. Manometric data derived from these healthy participants indicate both partial and complete head rotations can increase the duration of UES relaxation and decrease UES residual pressure. Chin tuck may be effective in increasing durations in the upper pharynx. Partial chin tuck (chin down) decreases UES residual pressure. Complete head rotation and chin tuck provide more overall benefit than partial maneuvers. However, for patients with limited head and neck mobility, partial posture changes impact the pharynx in similar ways and may provide clinically meaningful benefits. Additional research on patient populations is warranted.
Context:While clinical successes and descriptions have been reported in a few texts, no data exist to define the utility of flow phonation to improve voice quality in patients with laryngeal hyperfunction. Aims: To provide pilot data regarding the utility of three exercises (gargling, cup bubble blowing, and stretch-and-flow) to improve phonatory airflow during voicing in patients with laryngeal hyperfunction. Settings and Design: Outpatient Voice and Swallowing Center in a University Medical Center. Materials and Methods: Participants received five treatment sessions and were evaluated prior to treatment and after each session using a Phonatory Aerodynamic System to measure airflow during voicing tasks. Noise-to-harmonic ratio and perceptual voice measures were also obtained, as was self-perception of voice handicap. Statistical Analysis Used: Repeated All increased airflow and decreased laryngeal airway resistance over five sessions. Measures Analysis of Variance. Results: Six participants completed the protocol. All participants decreased self-perception of voice handicap and improved on noise-to-harmonic ratio and perceptual ratings of vocal quality. Conclusions: Data derived on a small sample of patients in an exploratory investigation suggest further research into the use of these three exercises to improve airflow with voicing and improve vocal quality in patients with laryngeal hyperfunction is warranted.
ObjectivesEdema is a frequent clinical observation following chemoradiation treatment (CRT) of oral/oropharyngeal cancer and is thought to contribute to post‐CRT swallowing impairment. Our aims were to reliably quantify pharyngeal edema pre‐ and post‐CRT from videofluoroscopic (VF) swallowing studies and to explore the relationship between edema and swallowing impairment. Swallowing impairment was captured using patient‐reported swallowing outcomes (EAT‐10) and with VF confirmation of impairment (DIGEST).Methods40 patients (24 M, age 38–76) with oral/oropharyngeal cancer received radiotherapy (70 Gy, 7 weeks) and 3 weekly doses of cisplatin. VF and EAT‐10 were completed pre‐ and 1‐month post‐CRT. Edema was captured by measuring posterior pharyngeal wall (PPW) thickness, vallecular space, and pharyngeal area (PA) on a single post‐swallow rest frame. Wilcoxon sign rank tests and paired t‐tests evaluated within‐subject changes in impairment and edema respectively. A linear mixed effect regression model explored the influence of time, patient‐reported outcomes, and functional impairment on measures of edema.ResultsSwallowing function (EAT‐10 and DIGEST) was significantly worse post‐CRT. PPW thickness (but not vallecular space and pharyngeal area) was significantly worse post‐CRT. PPW thickness was only significantly influenced by time (pre‐ vs. post‐CRT) but not by measures of swallow function.ConclusionOur findings establish the use of PPW thickness as a reliable measure of acute edema in post‐CRT treatment. In this small, retrospective sample, edema was not significantly correlated with either patient‐reported or measured swallow function. Prospective longitudinal work, examining the relationship between objective measures of edema, patient perception of impairment, and swallow function and biomechanics is warranted.Level of Evidence4.
