What is Actigraphy?
Actigraphy is the use of instruments, sensitive to movement
to record activity overtime. What
is actigraph? ACTIGRAPH
is device use in actigraphy. It is based on miniaturized acceleration sensor,
that translates physical motion to a numeric representation. 
How
is it performed? The
actigraph is initialized using the specific software, required data about the
patient is stored. The device is worn (around ankle/wrist). He is asked to press
the button on the actigraph when he lies in bed and on waking up. The duration
of recording can be from 24 hours - 5 days.
The actigraph is connected to a
computer, data is downloaded, the software automatically analyses the movements,
which are represented graphically. These movements are analyzed into PLM/Isolated
movements in leg up/down position. The summary is reported based on PLM/hr. in
down position. Indications: Caution:
Actigraphy is useful as a complementary assessment method
for Insomnia, RLS, shift work and for assessing sleep quality.
