14.10.3.3 Electrode position
Three stimulation channels are used.
In the Low back pain programme, endorphinic stimulation is always used on channels 1 and 2, while the
TENS stimulation is provided on channels 3 and 4.
For endorphinic treatment:
• Two small electrodes are placed on the most painful points, which can be easily located by palpitating
the lumbar paravertebral muscles.
For optimum eectiveness, the positive pole should preferably be positioned on the painful area.
• Two large electrodes with two outputs are placed a finger-width outside the small electrodes and are
attached to the negative poles of the two previous channels.
For the TENS treatment:
The free outputs of the two large electrodes are used to connect the third channel.
14.10.3.4 Patient position
The patient is placed in the position he/she finds the most comfortable: in the side lying or prone position,
taking care to use a cushion or a specially designed table to prevent lordosis.
