COMPEX 3 User Manual
A) Automatic mode
he stimulator will automatically detect
which channels are connected when in
automatic mode.
Total automatic
Full denervation with fixed parameters:
Pulse width: 100 ms
Period: 2000 ms
Programme duration: 8 min
NOTE: These are the default values
recommended in the Total manual mode.
Partial automatic
Partial denervation, with automatic
calculation of initial current ramp. The
width of the pulse before validation of the
ramp is 100 ms.
How it works
When you start the programme,
stimulation will automatically begin through
the first channel you are using. As soon as
you perceive a muscle response, confirm
the ramp by pressing the corresponding
+/- button (under the MEMO symbol).
The stimulator will display the value for this
channel (see Figure 31 below) and
automatically begin the search for the next
channel.
The Compex 3 can calculate and manage
4 different initial current ramps.
displayed above channel where
ramp search is being performed
displayed above inactive channels
(channels that are not connected).
displayed once intensity value for
corresponding channel has been validated.
31a: Press the On/Off button to stop the
programme and return to the previous
screen.
31b: Press the +/- button under the
MEMO symbol to confirm the current
intensity calculated during the ramp
search process. The width of the current
(pulse length) does not change during this
search. In the above example, the search is
being performed in channel 1. Once the
ramp is validated, the √ symbol will replace
the MEMO symbol and, where applicable,
the search will begin in the other channels.
31 c d e: the +/- buttons for the other
channels remain inactive while a search is
being performed.
When all the ramps for the active channels
have been calculated, the programme will
start automatically.
When you increase the stimulation
intensity, the pulse width will automatically
be modified to maintain the appropriate
initial ramp.
B) Manual mode
Total manual
Full denervation programme. This
programme works with rectangular pulses
and allows the following parameters to be
modified:
• Pulse width
• Period
• Programme duration
32a: Press the On/Off button to return to
the previous screen.
32b: Use the channel 1 +/- button to
select the parameter you wish to edit:
pulse width for each channel, period, or
programme duration.
32c: Use the channel 2 +/- button to edit
the value of the parameter you have
selected.
32e: Press the channel 4 +/- button to
confirm you wish to exit the programme.
NOTE: The default values of the
Total
manual
programme are the same as the
default values of the Total automatic
programme.
Partial manual
Partial denervation with choice of
stimulation parameters to define the
desired ramp.
