PATIENT PREPARATION
sEMG & STIM PATIENT PREPARATION (CONTINUED)
3. Review the specific Electrode Placement graphic for
positioning of the Reference (green lead) electrode.
NOTE: The electrodes may be placed for specific,
general, and quasi-specific biofeedback muscle or
muscle group activity.
For sEMG and sEMG + Electrical Stimulation operation,
refer to page 55.
8. Thoroughly cleanse the skin treating area.
NOTE: Thorough and proper cleaning of the
treatment area to remove any topical medication
and cream film as well as loose skin particles from
the treatment area is critical to the skin contact and
reception of the Electrodes during sEMG and sEMG +
Stim therapy.
Electrode Placement
1. Using DURA-STICK® 2 in (5 cm) electrodes, place the
Active (red and black lead) electrodes in the center of
the muscle belly and parallel with the muscle fibers.
2. Position the Reference electrode (green lead) in close
proximity to the treatment area.
• Using small electrodes and placing them closer
together will render a more specific reading of
muscle activity during sEMG and sEMG + Stim
therapy.
• The Active electrodes may be placed farther apart
to obtain a general reading of a muscle or muscle
group activity during the session.
• DJO recommends using only DURA-STICK®
electrodes to obtain the most accurate sEMG
feedback.
• Follow the electrode manufacturer instructions.
• Trimming or cutting electrodes may interfere with
the reception of sEMG data and may affect the
delivery of electrical stimulation in the sEMG + Stim
Modality.
