The post-treatment effect of NMES on the swallowing function in 784 post-stroke dysphagic patients was evaluated. A total of 10 (n = 748) out of 11 studies confirmed that NMES promoted an increase in the swallowing function in post-stroke dysphagic patients compared to control groups in all outcome measures. However, one study (n = 36) indicated that NMES did not differ between EG and CG. |
This review found that NMES associated with TT for swallowing could be an optional intervention to improve the swallowing function after stroke in the rehabilitation department. |

Intervention:
|
Most studies showed positive results for the use of electromyographic biofeedback as an adjuvant therapy to improve dysphagia. In all studies, the experimental group showed significant improvement over the control group or intervention group without electromyographic biofeedback (P<0.01 and P<0.05, respectively) on all outcome measures. The combination of conventional rehabilitation with adjuvant electromyographic biofeedback was more effective in improving dysphagia than conventional rehabilitation alone. |
Positive effects on the elevation of the larynx, on the improvement of swallowing functions and on the increase in the excursion and maximum elevation of the hyoid bone can be directly related to this therapy. Adjuvant therapeutic protocols with biofeedback electromyography have positive effects on the swallowing function. |

The chin-down maneuver was effective in decreasing aspiration. |
There is limited evidence of the potential effects of behavioral interventions in cases of dysphagia. Further studies are needed to evaluate its effectiveness with different populations. |
The supraglottic swallowing maneuver provided a decrease in aspiration, however its execution was difficult for patients. |
Head rotation showed oropharyngeal efficiency and a small improvement in the opening of the cricopharyngeal anteroposterior diameter (p > 0.05). The effect size was 0.42 for oropharyngeal efficiency and 0.67 for anteroposterior cricopharyngeal opening diameter. |
The Mendelsohn maneuver provided evolution in oral food intake. |
The Side lying maneuver helped in the oral intake of a patient. |

The biofeedback promoted a significant reduction in food residues, improvement in the evaluation of the DOSS scale and FOIS scale for both the intervention and control groups (1 study). Biofeedback also promoted a significant reduction in the number of coughing episodes, an improvement in voice quality (1 study), and an increase in patients' quality of life (3 studies). 2-week follow-up (1 study): Through the timed water swallowing test, the significant reduction in the liquid swallowing rate was analyzed (p=.034). There was also a change in the EMG duration parameters of the pre-motor time (p=.003) and a significant improvement in the pre-swallowing time (p<.001). |
The effectiveness of biofeedback in interventions for patients with PD and dysphagia is still uncertain, but it has shown promising results, requiring further investigation. |

Biofeedback did not improve swallowing function (FOIS, t=2, n=51, MD=1.10; IC 95% [-1.69, 3.89], or clinical outcome (tube feeding removal, t=2, n=53, OR=3.19; IC 95% [0.16, 62.72]. The biofeedback intervention had a significant positive effect on swallowing physiology, specifically hyoid displacement (t=3, n=90, MD=0.22; IC 95% [0.04, 0.40]. There was statistically significant heterogeneity between trials in measures of swallowing function and number of tube feedings (I2=70%-94%) and low in physiological measures (I2=8%). Accelerometry: improvement in functional intake (FOIS) P=0.014; hyoid displacement P=0.07 (1 study). Tongue manometry: change in maximum isometric pressure (p=0.03), tongue swallowing pressures (P=0.014) and motor function of swallowing structures - Mann Assessment of Swallowing Capacity (p=0.04) (1 study).

Videoendoscopy: after 40 days of therapy, more patients in the biofeedback group had the tube removed and full and unrestricted oral intake (p=0.041). |
Despite no evidence of improvement in functional outcomes and limited data available, therapy with biofeedback EMGs and accelerometry increased hyoid displacement. |

Eleven (73%) RCTs reported a positive outcome of the intervention used to remedy dysphagia: improved nutritional intake, increased fluid intake, improved swallowing ability, improved quality of life, improved swallowing physiology, reduced mortality or deficiency, increased mouth opening, maintenance of chemosensory function and maintenance of swallowing muscle composition. Two studies reported negative results for their primary variable. Three studies reported no change in intervention outcome. When reviewing the design quality rating and statistical conduct of each study, five studies that reported positive results could not be substantiated due to methodological and statistical issues. Two additional studies with low methodological rigor and statistical problems identified did not report better results for their sample and remained inconclusive. |
The results of the studies point to an increase in improvements with the use of RCT, although there are heterogeneous results. Further studies are needed to determine the best method of intervention. |

For the comparison “swallowing treatment with neuromuscular electrical stimulation versus swallowing treatment without neuromuscular electrical stimulation”, we found a standardized mean difference (SMD) of 1.27 (95% confidence interval (CI) = 0.51-2.02, P = 0.001) with significant heterogeneity (I2= 85%). The meta-analysis for the comparison of neuromuscular electrical stimulation alone and swallowing therapy showed a non-significant SMD of 0.25 (95% CI=–0.16–0.65, P = 0.23) without significant heterogeneity (I2= 16%). |
Swallowing therapy has shown to be more effective when associated with NMES in a short-term post-stroke population. Due to the limited amount of evidence, it was not possible to indicate whether NMES alone has better results than swallowing therapy. |

Swallowing exercises (9 studies): There was a significantly greater reduction in the occurrence of post-swallowing aspiration in the Shaker group (60%) compared to the traditional group (0%) (p = 0.028; Fisher's exact test). Patients who received TT showed significant improvements in several biomechanical measures of swallowing (laryngeal movement (p=0.009) and hyoid movement (p=0.044) in swallows of 3 ml paste and anterior laryngeal movement in liquid bolus of 3 ml (p=0.026; ANOVA). The program of prophylactic swallowing exercises (involving effortful and super-supraglottic swallowing, tongue retention maneuver, tongue retraction, and Mendelsohn maneuver) provided significant differences in FOIS, which were found in favor of the intervention group at 3 and 6 months after intervention (median 3-month intervention score 7 [range 5-7] vs. median control score 5 [range 3-7] p=0.03) and median 6-month intervention score 7 [range 6-7] vs. median control score 6 [range 3-7] (p=0.009; Fisher's exact test). |
Although the interventions present evidence that points to improvement in swallowing and mandibular mobility after HNC treatment, more high-quality studies are needed. |

Fifteen articles were retrieved evaluating a wide range of treatments that included texture-modified diets, general dysphagia therapy programs, non-oral feeding (enteral), drugs, and physical and olfactory stimulation. Among the studies, there was heterogeneity in the evaluated treatments and evaluated results, which made it impossible to use pooled analyses. Descriptively, these findings present emerging evidence that nasogastric tube feeding is not associated with an increased risk of death compared with percutaneous tube feedings; and general dysphagia therapy programs are associated with a reduced risk of pneumonia in the acute phase of stroke. |
Despite recently published RCTs, few use the same treatment and outcomes, thus limiting the evidence to support the medical efficacy of common dysphagia treatments used for patients recovering from stroke. |

The review compiles different techniques such as expiratory muscle strength training, postural techniques, oral motor exercises, video-assisted swallowing therapy, surface electrical stimulation, TTS, compensatory interventions, consistency change and electrical stimulation. Several rehabilitation therapies, such as expiratory muscle strength training or neuromuscular electrical stimulation, have been successful in swallowing and reducing the risk of asphyxia, aspiration or improving oropharyngeal function, presenting an improvement in degenerative function (coordination, speed and volume), quality of life and social relationships of individuals with PD, despite the limitations of the studies. Five articles showed improvement in the degenerative function after the application of the techniques, with a remarkable improvement in the quality of life and in the relationship of these patients with the environment. However, surface electrical stimulation did not show any positive influence on traditional speech therapy (1 study). |
This review gathered several techniques and treatments used for swallowing disorders in patients with PD, such as compensation strategies, swallowing maneuvers, training of expiratory muscle strength, in addition to postural treatment, traditional physiotherapy techniques, muscle training of the tongue, pharynx, larynx and respiratory system, and surface and neuromuscular electrical stimulation. Most results obtained with the use of these techniques described in the selected articles support an improvement in degenerative function, although these results are not of high quality in most studies. Further investigations into the clinical applicability of these therapies based on well-designed randomized controlled trials are needed with larger populations for a correct estimate of effectiveness. |

Chin-down: helped to eliminate aspiration (1 study). Super-supraglottic: helped to reduce swallowing disorders (1 study), prevented aspiration in five out of nine patients (1 study), improved tongue base retraction, longer duration of tongue base contact with the posterior pharyngeal wall, and increased lingual pressure against the posterior pharyngeal wall (1 study), improved laryngeal elevation and duration of closure (2 studies), significantly reduced duration and width of upper esophageal opening (1 study). Effortful swallow: increased pressure of the base of the tongue with the posterior pharyngeal wall, improvement in the ability to clear thicker liquid consistencies from the pharynx. However, the maneuver may promote increased muscular effort, leading to fatigue in the fibrous tissue more quickly. Mendelsohn maneuver: effective in eliminating aspiration, promoting complete contact of the base of the tongue with the posterior pharyngeal wall and increasing the duration of contact (1 study), increasing the duration of consistent laryngeal elevation and improving the duration of laryngeal closure. In addition, the maneuver provided improvement in 80% of patients in oral intake by at least 1 FOIS scale score (1 study). Supraglottic: for the patient with composite resection of the right retromolar triangle area, the maneuver promoted little benefit in changing the base of the tongue, pharyngeal and upper esophageal opening during swallowing, and swallowing physiology (1 study). |
There is currently limited evidence from six studies showing the positive effects of behavioral swallowing interventions in populations with structural disorders. Due to the range of structural deficits resulting from cancer and its treatments, further studies are needed to assess the effectiveness of the specific intervention. |

CTAR vs Shaker exercise: both promoted significant improvements in oral and pharyngeal phases (2 studies) and in PAS scores. CTAR also promoted improvement in the physiology of the oral cavity in swallowing, laryngeal elevation and epiglottic closure, reduction of vallecular residue and residue in the piriform sinuses. CTAR exercise: promoted significantly higher mean values and peaks of activation of the suprahyoid muscle and caused lower activation of the sternocleidomastoid muscle. CTAR vs. traditional dysphagia treatment: CTAR showed significantly greater improvement in PAS than traditional treatment. CTAR vs. Shaker vs. chin flexion exercise with Theraband: significant increase in anterior tongue pressure with CTAR and with chin flexion with Theraband. |
CTAR exercise more selectively activates the suprahyoid muscle and is an effective therapeutic exercise to improve swallowing function in patients with dysphagia. As it is less strenuous than the Shaker exercise, it requires less physical load and effort, allowing greater adherence. |

There is low-level evidence to support the use of TTS. Current best practice would be to use the TTS on a case-by-case basis, following a detailed instrumental assessment and efficacy assessment for an individual. |

Compared to the control groups, NMES and TT significantly improved swallowing function by a SMD of 0.62 (95% IC = 0.06 to 1.17; I2 = 89%). The SMD of the remaining eight studies was 0.92 (95% IC = 0.19 to 1.64; I2 = 90%). Stimulation muscle groups - Studies stimulating suprahyoid muscle groups: negative SMD value of 0.17 (95% IC = −0.42 to 0.08) without significant heterogeneity (I2 = 0%). Studies stimulating the infrahyoid muscle groups (SMD = 0.89; 95% IC = 0.47 to 1.30; I2 = 0%). Studies stimulating the suprahyoid and infrahyoid muscle groups (SMD = 1.40; 95% CI = 1.07 to 1.74; I2 = 91%). Adverse effect: no serious adverse effect associated with NMES was reported, only pain (2 studies), transient pain, which disappeared immediately after discontinuing NMES (1 study), and mild pain, which ceased after the adjustment of stimulation intensity (1 study). |
There is no solid evidence to conclude about the effectiveness of neuromuscular electrical stimulation in swallowing disorders. Larger-scale, well-designed randomized controlled trials are needed to reach robust conclusions. |

Significant improvement was seen in the NMES group compared to the TT group at SMD 0.77 (95% CI: 0.13 to 1.41, p = 0.02). The heterogeneity became small (I2 = 0%). |
The meta-analysis showed that NMES is more effective for the treatment of adult patients with dysphagia of variable etiologies than TT. However, in patients with dysphagia after stroke, the effectiveness of NMES and TT was comparable. Considering the limitations described above, caution should be exercised when interpreting the results. We recommend that NMES is useful for the treatment of dysphagia, high quality studies with large numbers of patients are needed. |

NMES was significantly superior to TT with an overall pooled score value of 0.5 (95% CI: 0.2 to 0.8, p = 0.001). It seems that the result was relatively stable. An additional sensitivity analysis was performed excluding the study in which CG patients completed treatment at home. With the overall combined score value of 0.46 (95% CI: 0.15 to 0.77, p = 0.004), there appear to be statistically significant differences between the two methods. The result was relatively stable. |
In the subgroup analysis according to dysphagia etiology, there was no significant difference between NMES and TT in the stroke group, which had a pooled MPD value of 0.78 (95% CI: −0,22 to 1.78, p = 0·13, 4 studies, 175 patients). However, subgroup analysis of non-stroke patients, including cancer and PD patients, showed statistically significant differences between the two interventions, and the overall combined SMD value was 0.63 (95% CI: 0.24 to 1.02, = 0·002). |

Statistically significant improvement in patients with dysphagia who were treated with NIBS immediately after stimulation compared to patients who underwent simulated stimulation (SMD = 1.08, 95% CI = 0.29-1.88, I2 = 72%). Evaluation results at 1 month after stimulation (SMD = 2.75, 95% CI = 1.47-4.04, I2 = 70%) and at 2 months (SMD= 3.54, 95% CI = 2.58-4.50, I2 = 0%) showed statistically significant improvement. Subgroup analysis based on intervention use in the rTMS group versus the simulated stimulation group (SMD = 1.61, 95% CI = 0.59-2.63, I2= 67%) showed significant improvement. No statistically significant difference in the tDCS group versus the simulated stimulation group (SMD = 0.54, 95% CI = -0.05-1.62, I2= 68%). In the subgroup analysis based on stimulation site, the contralesional site stimulation group showed statistically significant improvement compared to the sham stimulation group (SMD = 0.90, 95% CI = 0.16-1.64, I2 = 0%), while the ipsilesional site stimulation group showed no improvement (SMD = 1.015, 95% CI = -0.69–2.79, I2 = 88%). No statistically significant difference between the ipsilesional stimulation group and the contralesional stimulation group (I2= 0%, p = 0.87). |
The results indicate that NIBS treatment for post-stroke dysphagia has a beneficial effect compared to simulated stimulation. Furthermore, NIBS reveals synergistic effects over time. In the subgroup analysis, rTMS stimulation offered beneficial effects compared to simulated stimulation. No significant differences regarding the stimulation site (ipsilesional or contralesional stimulation) were observed. No complications of NIBS were reported in this analysis. The small number of studies and the lack of long-term follow-up are the main limitations of this review. Future studies would benefit from standardization of results and stimulation parameters to decrease variability and heterogeneity of results and long-term outcomes. |

Nine studies were analyzed: 4 on aphasia, 3 on dysphagia, 1 on dysarthria in PD, and 1 on language deficits in Alzheimer's disease. All aphasia studies used low-frequency rTMS to stimulate Broca's homologous area. High-frequency rTMS was applied on the pharyngoesophageal cortex of the left and/or right hemisphere in the studies on dysphagia, and on the left dorsolateral prefrontal cortex in the studies on Parkinson's and Alzheimer's. Two studies on aphasia and all studies on dysphagia showed a significant improvement in the disorder compared to the placebo group. The other 2 studies on aphasia found benefit restricted to subgroups with severe cases or lesions in the anterior portion of the cortical area of language, respectively, while the study on Alzheimer showed specific positive effects for listening comprehension. There were no changes to vocal function in the Parkinson's study. |
The benefits of the technique and its applicability in neurogenic disorders related to communication and swallowing are still uncertain. Therefore, further randomized clinical trials are needed to clarify the optimal stimulation protocol for each disorder studied and its real effects. |

It was observed that the most relevant effects of isolated orofacial myofunctional therapy in adults include reduction in daytime sleepiness and snoring, better sleep quality, partial decrease in AHI and partial increase in minimum blood saturation. Randomized controlled and blind clinical trials are few and are important to confirm the effects of the technique based on evidence and guide therapeutic decisions considering the evaluation and diagnosis and the patient's phenotype for an accurate prognosis. |
Six studies showed a decrease in the AHI, five studies showed an improvement in minimum SpO2 saturation, sleepiness scale scores and snoring. Despite the methodological differences, items that make it difficult to compare the results, the studies surveyed confirm the positive effects of OMT for patients with OSA. |
