Transmembrane Electromyography (TM-EMG) for the Assessment of Neuromuscular Function in the Oropharynx

Brief description of study

This is a pilot study to examine the diagnostic utility of a novel transmembrane surface sensor, and compare signals obtained with the transmembrane sensor to conventional needle EMG signals from healthy volunteers to those with documented neurologic pharyngeal muscle dysfunction (ALS and muscular dystrophy) and to those with severe OSA.

Detailed Study Description

Transmembrane electromyography (TM-EMG) may be a feasible and valid non-invasive EMG technique for detecting neuromuscular (NM) impairment. This study will assess whether, in healthy volunteers and participants with known obstructive sleep apnea (OSA) and other NM diseases involving the oropharynx, the same characteristic motor unit potentials obtained on conventional needle EMG (NEMG) can be obtained using a TM-EMG sensor. The purpose of this study is to demonstrate whether the TM-EMG sensor can provide the same diagnostic accuracy as the concentric needle electrode for the diagnosis of NM diseases. Having demonstrated diagnostic similarity of TM-EMG to NEMG, the secondary aim of this study is to confirm that NM disturbance of oropharyngeal striated muscles in participants with OSA can be elicited with the TM-EMG sensor.
