MicroMini-Motionlogger and Family of Sensors
Wireless single sensor units
which, together with the Micro-Mini Motionlogger Actigraph, allow multi-parameter
collection downloaded all with a common Interface and integrated in ACTION4
software. On the subject, in the room and under the bed....Here's how
the MicroMini Family of Sensors can
enhance your actigraphic sleep studies:
1) The MicroMini
Motionlogger¨ is the culmination of actigraphic technology that
is the industry standard. Measure either
frequency or intensity of movement, with over 3 weeks of recording time. High
sensitivity means movements within sleep can be used to document restless
sleep scoring algorithms in study after study Motionloggers
have consistently produced the highest correlation
with polysomnographically scored sleep.
Temperature Measurement First described over 10 years ago, the distal
temperature rise that occurs during sleep onset can now be easily recorded (4¡C
temperature rise shown above) with a MicroMini Temperature sensor on the
Temperature Taped to the ankle in the above example, it's clear that the
bed temperature rise precedes the distal temperature rise.
Temperature is a key ingredient in sleep hygiene. Record
it easily from the nightstand!
Light Levels Lights on and off can be documented, and make certain the
room is dark enough for sleeping great for shift work studies!
Sound Levels Snoring bed partner causes a subject to awaken (see above).
channel helps determine time in bed. A
MicroMini Motionlogger in high sensitivity mode is placed under the
mattress (dubbed the Princess and the Pea method) for determining time
in bed (9). Note above that
awakenings that result in leaving the bed can be discerned.
