“…This observation calls for further improvement in the management of dysphagic patients. Recent studies indicate that functional magnetic or electrical stimulation may improve dysphagia as compared to conventional swallowing therapy, but these results need to be confirmed by larger studies [ 32 , 33 ]. There could be a need for such novel approaches, as swallowing dysfunction may persist in many patients for a longer time [ 34 , 35 ].…”

BackgroundReported frequency of post-stroke dysphagia in the literature is highly variable. In view of progress in stroke management, we aimed to assess the current burden of dysphagia in acute ischemic stroke.MethodsWe studied 570 consecutive patients treated in a tertiary stroke center. Dysphagia was evaluated by using the Gugging Swallowing Screen (GUSS). We investigated the relationship of dysphagia with pneumonia, length of hospital stay and discharge destination and compared rates of favourable clinical outcome and mortality at 3 months between dysphagic patients and those without dysphagia.ResultsDysphagia was diagnosed in 118 of 570 (20.7%) patients and persisted in 60 (50.9%) at hospital discharge. Thirty-six (30.5%) patients needed nasogastric tube because of severe dysphagia. Stroke severity rather than infarct location was associated with dysphagia. Dysphagic patients suffered more frequently from pneumonia (23.1% vs. 1.1%, p<0.001), stayed longer at monitored stroke unit beds (4.4±2.8 vs. 2.7±2.4 days; p<0.001) and were less often discharged to home (19.5% vs. 63.7%, p = 0.001) as compared to those without dysphagia. At 3 months, dysphagic patients less often had a favourable outcome (35.7% vs. 69.7%; p<0.001), less often lived at home (38.8% vs. 76.5%; p<0.001), and more often had died (13.6% vs. 1.6%; p<0.001). Multivariate analyses identified dysphagia to be an independent predictor of discharge destination and institutionalization at 3 months, while severe dysphagia requiring tube placement was strongly associated with mortality.ConclusionDysphagia still affects a substantial portion of stroke patients and may have a large impact on clinical outcome, mortality and institutionalization.

“…23 Palatal electrical stimulation has also been used by some researchers to initiate sensory feedback, so as to get swallow reflex involuntarily, with controversial results. 24 Momosaki et al 25 used Functional Magnetic Stimulation (FMS) and noted a statistically significant improvement in swallowing function, both in terms of capacity and speed of swallowing.…”

Swallowing and breathing are complex and highly coordinated functions. These functions depend on well-coordinated work of many organs with larynx and nervous system playing a critical role. Disturbance in one of these functions negatively affects the other. Surgical airways like tracheostomies are required in a number of situations, including but not limited to major head and neck procedures, cases with decreased lung function, excessive bronchial secretions and cases requiring neuro-rehabilitation when prolonged airway is required for mechanical ventilation. Extensive neuro-rehabilitation is required since patients with surgical airway may develop swallowing difficulties including dysphagia and/or aspiration with a very high prevalence, which can pose a threat to life. This article reviews the current status of the diagnostic and therapeutic modalities for swallowing difficulties with special emphasis on current neuro-rehabilitative strategies. Electronic databases including Medline, Web-of-science, Cochrane Library, and Google scholar were used for literature search. Downloaded articles were subsequently assessed independently by two researchers to determine suitability for inclusion in the study.Key words: Neurorehabilitation, Tracheostomy, Transcranial direct current stimulation, Transcranial magnetic stimulation, swallowing difficulty

“…11 Although it is similar to functional electrical stimulation, FMS has a deeper reach and generates less pain. 11 Reports have demonstrated the beneficial role of FMS in improving swallowing and respiratory functions after stroke, 12,13 but to our knowledge, no study has yet investigated its role in motor dysfunction. Therefore, this study aimed to explore the efficacy of FMS on upper extremity function in stroke patients.…”

Efficacy of functional magnetic stimulation in improving upper extremity function after stroke: a randomized, single-blind, controlled study

et al. 2020

Objective To clarify the efficacy of functional magnetic stimulation (FMS) in improving hemiplegic upper extremity function in patients with sub-acute stroke. Methods In this randomized controlled trial, 40 sub-acute stroke patients with hemiplegia were recruited from inpatient wards in the Department of Rehabilitation and randomly assigned to two groups. In the FMS group, magnetic stimulation was applied to extensor muscle groups of the affected upper extremity. In the low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) group, stimulation was applied to the contralesional primary motor cortex. All patients received occupational therapy. Hand and upper extremity motor function was evaluated using the Fugl–Meyer Assessment for upper extremity (FMA-UE), and the Barthel Index (BI) evaluated daily living abilities. Results The FMA-UE and BI scores were significantly increased in both groups following stimulation. Furthermore, a significant between-group difference was observed in both FMA-UE and BI scores after 2 weeks of therapy. In the FMS group, 6 of 19 patients regained wrist and finger extension abilities, but only 2 patients regained equivalent motor skills in the LF-rTMS group Conclusions FMS improves paretic upper extremity function and leads to better recovery of motor activity than LF-rTMS. FMS may be a novel modality to improve motor function.
