“…The findings are congruent with previous investigations [24]. The NF group demonstrated similar SERs, as reported by Ng et al [27]. An increase in the SER in the VVF group is consistent with the findings of Lucca and Recchiuti [26], suggesting an increase in exercise performance when sEMG is employed.…”

Background/Aims: The effortful swallow is a common treatment intervention requiring increased intensity to facilitate adaptations and modify swallow kinematics. The type of feedback and bolus volume provided may influence the intensity of the effortful swallow. To determine the increased effortful swallow intensity, a clinician can collect the peak amplitude of an effortful swallow and a typical swallow and compute a “swallow effort ratio” (SER). Dividing the effortful swallow surface electromyography (sEMG) peak amplitude by the typical swallow sEMG peak amplitude derives the SER. A higher SER suggests increased intensity. An increase in the SER may have clinical relevance in swallowing therapy as a threshold of intensity is required to elicit neuroplastic change. The purpose of this investigation was to determine whether sEMG visual and clinician verbal feedback increases the SER. Additionally, the investigation examined whether the SER is influenced by different liquid bolus volumes. Methods: Eighty-two nondysphagic, healthy adults were assigned at random to 2 groups. One group received no feedback, and the other received verbal and visual feedback while performing typical and effortful swallows at 3 liquid volumes. Results: An analysis of covariance compared the typical and effortful peak swallow amplitudes among 3 volumes in the 2 feedback groups. There was a significant effect on the peak amplitude values by feedback group F(2, 79) = 22.82, p < 0.001. There were no differences in peak amplitude by volume regardless of feedback F(2, 78) = 0.413, p = 0.663. Conclusion: It appears that sEMG visual and clinician verbal feedback increases the SER, which may be a surrogate for intensity. An increased SER may have a positive effect on swallow intervention as intensity is known to influence outcomes of exercise and elicit neuroplastic change.

“…The clinician can collect the peak amplitudes of the effortful swallow and the typical swallow and compute a "swal-low effort ratio" (SER). Ng et al [27] first reported SER, which is the effortful swallow sEMG peak amplitude divided by the typical swallow sEMG peak amplitude. A higher SER may suggest increased intensity.…”

“…Second, effortful swallowing effectively improves swallowing function in dysphagia rehabilitation by activating and increasing the strength of various oropharyngeal muscles, including the tongue and suprahyoid muscles, and increasing intraoral pressure during swallowing. [23,24] Therefore, more forceful swallowing is required to maximize improving the swallowing function through effortful swallowing. The tension of KT applied in this study may have played a role in resistance, such that patients could swallow strongly using a greater force, which helps improve swallowing function through the synergistic effect of effortful swallowing.…”

Background: A dysphagia rehabilitation method using kinesiology taping (KT) was recently introduced, and its potential for clinical efficacy was demonstrated by evaluating muscle activity and thickness. However, its effect on the swallowing function in patients with dysphagia remains unclear. This study aimed to investigate the effects of effortful swallowing against KT resistance on the swallowing function in patients with post stroke dysphagia. Methods: Thirty patients with poststroke dysphagia were recruited and randomly assigned to the experimental and placebo groups. In the experimental group, the KT was attached to the front of the neck (the hyoid bone between the sternum) with a tension of approximately 70% to 80%, and effortful swallowing was performed against the KT tension. In contrast, the placebo group performed effortful swallowing with KT applied at the same location without tension. The intervention was performed 30 times/day, 5 days/week for 6 weeks. The videofluoroscopic dysphagia scale (VDS) and penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study were used to analyze oropharyngeal swallowing function. Results: The experimental group showed statistically significant improvements in the oral and pharyngeal phases of the VDS (P = .029 and .007, respectively) and PAS (P = .034) compared with the placebo group. Effect sizes were observed for the oral (0.3) and pharyngeal phases (0.5) of the VDS and PAS (1.1). Conclusion: This study demonstrated that effortful swallowing against resistance to KT is an effective therapeutic exercise for improving the swallowing function in patients with poststroke dysphagia.
