“…The second aim is to diagnose and follow-up the dysphagic patients objectively and quantitatively. The “dysphagia limit”[ 55 , 59 ] and “SWS”[ 60 - 63 ] are the methods used to achieve this aim. The third aim is to identify spontaneous swallowing (SS) and distinguish it from voluntarily-induced swallows using polygraphic EMG methods.…”

“…The third aim is to identify spontaneous swallowing (SS) and distinguish it from voluntarily-induced swallows using polygraphic EMG methods. This can be important in the evaluation of oropharyngeal dysphagia in uncooperative patients, such as comatose, demented patients and in advanced cases of PD (for details of the single-bolus analysis and dysphagia limit methods, please refer to[ 52 , 55 , 59 , 63 - 66 ]).…”

Parkinson’s disease (PD) is a chronic, neurodegenerative movement disorder that typically affects elderly patients. Swallowing disorders are highly prevalent in PD and can have grave consequences, including pneumonia, malnutrition, dehydration and mortality. Neurogenic dysphagia in PD can manifest with both overt clinical symptoms or silent dysphagia. Regardless, early diagnosis and objective follow-up of dysphagia in PD is crucial for timely and appropriate care for these patients. In this review, we provide a comprehensive summary of the electrophysiological methods that can be used to objectively evaluate dysphagia in PD. We discuss the electrophysiological abnormalities that can be observed in PD, their clinical correlates and the pathophysiology underlying these findings.

“…SWS is technically similar to the "3 ounce test" and "timed test, " but these two SW tests are performed by clinical observation during which 90-150 mL of water should be swallowed as fast as possible without interruption (60,61). SWS is assessed either by the collection of radiological (57,62) or physiological recordings (16,63,64). During SWS, there are rhythmic or pseudorhythmic SW sequences with- When recordings of SWS are collected while using a nasal airway sensor for respiration and SM-EMG, we can observe approximately 1 sec interswallow intervals between each couple of swallow deflections in the SM-EMG, during which the respiratory recordings demonstrate breath holding that results in a swallow apnea period in normal subjects.…”

“…These kinds of electrophysiological signs occurred frequently in pontobulbar infarction, as is seen in Figure 5b. The arhythmic SWS and compensatory respiratory cycles during swallow intervals were the most important dysphagic components of the brainstem infarctions (16,51,63). Although it is not systematically studied, the cardiac rhythm also has influence in some patients with Wallenberg syndrome (LMI).…”

Electrophysiological Evaluation of Dysphagia in the Mild or Moderate Patients with Multiple Sclerosis: A Concept of Subclinical Dysphagia

Swallowing mechanism and neurogenic dysphagia in MS have been rarely studied by electromyographical (EMG) methods. This study aims to evaluate the presence of subclinical dysphagia in patients with mild multiple sclerosis (MS) using electrophysiological methods. A prospective study of 51 patients with relapsing remitting multiple sclerosis and 18 age-matched healthy adults was investigated. We used electromyography to measure the activity of the submental muscles during swallowing. Electrophysiological recordings of patients were obtained during relapse, after relapse, and at any time in remission period. Clinical dysphagia was found in 12% of MS patients, while electrophysiological swallowing abnormalities were encountered in 33% of patients. Subclinical dysphagia was determined in 35% of patients during an MS relapse, in 20% of patients after a relapse, and in 25% of all 51 patients in the remission period based on EMG findings. Duration of swallowing signal of submental muscles in all MS patients was found to be longer than in normal subjects (p = 0.001). During swallowing of 50 ml of sequential water, the compensatory respiratory cycles occurred more often in MS patients than normal subjects, especially during a relapse (p = 0.005). This is the first study investigating swallowing abnormalities and subclinical dysphagia from the electrophysiological aspect in MS patients with mild disability. The electrophysiological tests described in this study are useful to uncover subclinical dysphagia since they have the advantage of being rapid, easy to apply, non-invasive, and without risk for the patients.
