17. REM TST in adults: 20 to 25%
18. Sawtooth waves: Trains of sharply contoured 2-6 Hz
waves Max amplitude over the centrals
often preceding
bursts of REM's R
19. Transient muscle activity: short irregular bursts of EMG
activity duration < .35 secs
,superimposed on low EMG tone
Seen in chin, anterior tibial EMG, EEG or EOG
20. Arousals: abrupt shift in EEG frequency > 16 Hz for at least 3 seconds with 10 seconds of sleep preceeding the
change
In REM a concurrent increase in submental EMG lasts at least 1 sec
21. LM: .5 to 10 seconds
Min amplitude 8 uV increase in EMG voltage
End event when at least .5 secs where EMG does NOT exceed 2 uV above resting
EMG Do not score .5 sec preceding event or 2.5 seconds following the event
22. PLM: At least 4 LM's
Period length between LM to include them as part of a PLM series 5 to 90
sec 2 legs separated by <5 sec is 1 LM
An arousal or limb movement in a PLM series is associated with each other if it is <.5 sec
23. Sustained muscle activity (tonic activity) in REM: REM sleep with at least 50% of the epoch
having a chin EMG amplitude greater than the minimum amplitude in NREM
24. Excessive transient muscle activity (phasic activity): In 30 sec epoch of REM divided into
10 sequential 3 sec mini epochs at least 50% (5) of the mini epochs contain bursts of transient muscle activity
25. Rapid eye movement sleep behavior disorder (RBD): Excessive transient muscle activity
bursts are .1 to 5 seconds in duration and at least 4 times as high in amplitude as the background EMG activity
26. Bruxism: tonic (sustained) or phasic (brief) elevations of chin EMG twice the amplitude of background EMG
EMG activity at least .25 to 2 seconds with at least 3 elevations in a regular sequence
At least 3 seconds of stable background chin EMG must occur between new episode
Audio scored with min of 2 audible tooth grinding episodes per night in the absence of epilepsy.
27. Rhythmic Movement Disorder: .5
to 2 Hz At least 4 to make a cluster
Min amplitude of burst is 2 times that of the background EMG
, 28. Scoring Apnea Device: oronasal thermal sensor or PAP device flow signal
29. Hypopnea Device: Nasal pressure signal or PAP device flow signal
30. Cheyne Stokes Scoring: >3 consecutive events with cycle length >40
sec or >5 events per hour of sleep in >ds2 hours of recorded monitoring

normal 80-94% insomnia <
80%
