RPSGT Exam study series: Movement Rules Questions And Answers With Verified Solutions

2 optional EMG placements for detecting TMA in REM sleep are - The Flexor digitorum superficialis and the Extensor digitorum communis At least how many minutes of NREM sleep with EFM must be recorded? - 20 minutes At least how mnay EMG potentials per minute must be recorded? - 5 EMG potentials per minute Elevations of chin EMG must be how high compared to background EMG to be characterized as bruxism? - at least twice the amplitude of background EMG Excessive transient muscle activity (phasic activity) in REM sleep may be characterized by - bursts .1-5.0 seconds in duration and at least 4x higher than amplitude of background EMG activity lasting at least half the epoch. For detecing bruxism, additional electrodes may be placed where? - on the masseter muscle For diagnosis of RBD, what is required? - Audio-equipped video PSG For diagnosis of RMD, what is required? - video PSG For monitoring leg movements, Impedances must be less than how many ohms? - 10,000 ohms How far should leg electrodes be placed on the anterior tibialis? - 2-3 cm apart or 1/3 the length of the AT muscle How long must elevations of chin or masseter EMG activity last to be scored as bruxism? - .25-2 seconds in durationHow many elevations of bruxism must occur in a regular sequence to be scored? - At least 3 elevations must occur in regular sequence How my bruxism be scored in addition to PSG EMG Data? - Through 2 audible tooth grinding episodes / night of PSG in the absence of epilepsy If a leg movement is detected on 2 different legs, what is the duration of time necessary for them to be scored separately? - greater than 5 seconds apart REM Behavior DIsorder is scored by either or both of the following features: - A. Sustained muscle activity in REM sleep in chin EMG B. Excessive transient muscle activity during REM in the chin or limb EMG Sustained muscle activity (tonic activity) in REM sleep is characterized by - an epoch of REM sleep with at least 50% of the duration of the epoch having a chin EMG amplitude greater than the minimum amplitude demonstrated in NREM sleep The maximum frequency for scoring rhythmic movements is - 2.0 Hz the minimum amplitude of an individual rhythmic burst is how much higher than the background EMG activity? - twice as high The minimum frequency for scoring rhythmic movements is - 0.5 Hz the minimum number of individual movements required to make a cluster of rhythmic movements is - 4 movements The period length between LMs required to include them as part of a PLM series is - 5 to 90 secondsWhat is a HFT? - Hypnagogic Foot Tremor What is a term for a series of brief (phasic) muscle contractions as seen in bruxism? - Rhythmic masticatory muscle activity (RMMA) What is an ALMA? - Alternating Leg Muscle activation What is an EFM? - Excessive Fragmentary Myoclonus What is bruxism? - tooth grinding at night What is the duration of time that an LM and an arousal are associated, regardless of whether or not the LM occurs before or after the arousal? - .5 seconds
