However, studies confirming how exercise physiology changes when performing ES continuously over multiple sets in clinical practice are limited. This study aimed to determine the effect of visual biofeedback using the Iowa Oral Performance Instrument (IOPI) on the muscle activity of the floor-of-the-mouth (FOM) and oral swallowing pressure during ES exercise. Forty-five healthy older adults (mean age 76.1 ± 4.48y) participated in this randomized crossover study with two conditions. In the visual biofeedback condition using the IOPI, the participants were presented with a value corresponding to 80% of the maximum isometric pressure of the posterior oral tongue measured at baseline and asked to exceed the target value while performing ES. In the no-feedback condition, the IOPI screen was blocked to ensure that information regarding the swallowing pressure during ES was not provided. In the biofeedback condition, participants showed a significantly higher oral swallowing pressure from Sets 3-8 compared with the no-feedback condition (p < 0.05). In the no feedback condition, FOM muscle activity was significantly lower in Set 4 than in the Set 1 (p < 0.05). To improve the strength of the tongue and FOM muscles through ES exercise, providing biofeedback using the IOPI may be beneficial for maintaining a consistently high level of exercise intensity.

The aim was to assess reliability of the tool among speech-language pathology (SLP) raters practicing at multiple sites before and after review of a DIGEST training manual and evaluate confidence of DIGEST use pre-and post-training. Thirty-two SLPs from 5 sites participated in a blinded longitudinal DIGEST rating study. Raters were provided a standardized training set of MBS (n = 19). Initial SLP ratings (round 1, R1) were followed by a 2-4 week break before raters rated a re-keyed MBS set (round 2, R2). A minimum 4-8 week wash-out period then preceded self-study of the DIGEST training manual which was followed by a final rating (round 3, R3) and a post-manual survey afterwards. Baseline reliability (R1) of overall DIGEST was on average k = 0.70, reflecting agreement in the substantial range. Seventy-five percent of raters (24/32) demonstrated reliability ≥ 0.61 in the substantial to almost perfect range prior to training. Inter-rater reliability significantly improved from R1 to R3 after review of the DIGEST manual, with the largest change in DIGEST-Efficiency (mean change: DIGEST k = .04, p = .009, DIGEST-Safety k = .07, p = 0.03, and DIGEST-Efficiency k = .14, p = 0.009). Although DIGEST reliability at baseline was adequate in the majority of raters, self-study of the DIGEST training manual significantly improved inter-rater reliability and rater confidence using the DIGEST method, particularly when assigning DIGEST-Efficiency grade.
