Synopsis of Subject: This subject will focus on the use of electromyogram (EMG) to measure and monitor different skeletal muscle movements on the body throughout the sleep study. The student will be introduced to movement disorders such as Restless Leg Syndrome (RLS) and Periodic Limb Movement Disorder (PLMD), their clinical presentation in the sleep center and their typical treatment options. The subject will review the scoring criteria relating to movement disorders, including bruxism, rhythmic movement disorders, and REM Behavior Disorder. The student will be introduced on how to perform equipment calibration checks as well as physiologic calibration checks to confirm that high quality recording will be performed. A review of proper patient monitoring techniques will also be discussed and include topics like selecting the appropriate recording montage, proper documentation throughout the night, responding to patient needs and responding to recording artifact.
Student Will Learn to Do: How to properly apply the different EMG electrodes on the patient and monitor the EMG tracing within the recording montage, how to define and recognize movement disorders such as PLMD and bruxism, how to define and score periodic limb movements, how to differential between sleep disordered breathing events or true neurological movements not associated to a sleep disordered breathing issues. The student will also learn how to properly perform calibration checks and how to identify and respond to unwanted recording artifact thought the night.
