Questions and Answers11
A periodic limb movement series is defined as 4 leg movements with a duration between 5 and
60 seconds. - ANSWERS-False
Arousals are scored with PLMs as long as they occur within ____ seconds of the movement. -
ANSWERS-0.5
A series of repetitive bruxism movements is called "alternating masticatory muscle activity." -
ANSWERS-False
Excessive fragmentary myoclonus is described as a benign movement because it does not have
any clinical consequences - ANSWERS-True
For the leg activity to be considered alternative leg muscle activation, there must be a series of
at least 3 alternating limb movements. - ANSWERS-False
In order to score rhythmic order disorder, there must be ___ individual clusters of moments that
are ___ the amplitude of the background EMG activity. - ANSWERS-4, 2x
Leg movements should not be scored if they are within 0.5 seconds of a respiratory event. -
ANSWERS-True
PLMs in sleep are defined as leg movements with a duration between ____ and ____? -
ANSWERS-0.5 and 10 Sec
, REM behavior disorder can be identified by a sustained chin EMG activity in REM. The epoch
will show at least 50% duration of the amplitude increase than the maximum amplitude seen in
NREM sleep. - ANSWERS-False
The best placement to record movement activity typical of rhythmic movement disorder (RMD)
is over the ____ muscles. - ANSWERS-Paraspinal
The minimum amplitude of a leg movement in a PLM series, to classify it as a leg jerk, it must be
___ microvolts above the baseline limb EMG signal - ANSWERS-8
CO2 monitoring, using either end-tidal or transcutaneous sensors, is mandatory in children for
the scoring of - ANSWERS-Hypoventilation
Hypnagogic hypersynchrony - ANSWERS-Occurs at sleep onset
In a limited channel study in infants, apneas associated with severe oxygen desaturation may
lead the scorer to infer that the infant - ANSWERS-is in REM
In children, central apneas lasting less than 20 seconds and not accompanied by a 3% oxygen
desaturation or arousal are - ANSWERS-normal
In contrast to alpha rhythm in adults, the dominant posterior rhythm in infants is - ANSWERS-
Slower
Infants less than 2 months of age, a distinctive EEG pattern associated with NREM or quiet sleep
and consisting of high-voltage slow waves separated by 4 to 8 seconds of lower-voltage mixed
frequency waves is called - ANSWERS-trace alternant
In infants, episodes of 3 or more central apneas lasting more than 3 seconds and separated by
less than 20 seconds of normal breathing are called - ANSWERS-Periodic Breathing
