|Condition or disease||Intervention/treatment||Phase|
|Obstructive Sleep Apnea Amyotrophic Lateral Sclerosis Muscular Dystrophies Healthy||Device: Transmembrane EMG Oropharynx Probe||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||23 participants|
|Intervention Model:||Single Group Assignment|
|Intervention Model Description:||This is a prospective, cohort, pilot study with blinded data analysis and two physician testers to assess intertester reliability and device usability. Volunteers will include healthy adults, participants with documented neurologic pharyngeal muscle dysfunction (ALS and muscular dystrophy), and participants with severe OSA. For each participant diagnostic properties of EMG studies will be assessed using a conventional needle and TM-EMG sensor in pharyngeal muscles.|

Experimental: EMG Testing
Examination of the electromyographic signal from oropharyngeal muscles obtained using an investigational transmenbrane sensor attached to a rigid probe and an FDA-approved very fine concentric needle electrode (Ambu Neuroline 25 mm x 30G).
