STARTING, STOPPING, AND INTERRUPTING COMBINATION THERAPY
Combination therapy consists of using electrotherapy and
ultrasound therapy simultaneously. You may choose to use
one or both channels of electrotherapy in conjunction with
ultrasound.
Combination therapy utilizes the ultrasound modality
in conjuction with High Voltage Pulsed Current (HVPC),
Premodulated, or Interferential to generate a therapeutic effect.
In this mode of therapy, the sound head of the ultrasound
applicator becomes one half of the electrical circuit. An
electrode attached to the black (-) Lead Wire completes the
circuit.
To do this, do the following:
1.
Follow all appropriate procedures listed in the section
entitled "Electrotherapy Patient Preparation" on page 26
and "Ultrasound Patient Preparation" on page 27.
2.
Connect the Lead Wires to the appropriate electrodes.
For example, for all waveforms used by Channel 1 (all
waveforms except Interferential), use the black (-) Lead
Wire as the negative and the applicator as the positive.
For the Interferential waveform, you will use three lead
wires and the applicator for combination therapy: use the
black (-) Lead Wire for Channel 1 as the negative electrode,
the applicator as the positive, and the other Lead Wires for
channel 2 as you would for an electrotherapy treatment.
NOTE: Do not use unnecessary force to connect the
electrodes to the Lead Wires.
3.
Place the self adhesive electrodes on the sites prescribed
by a qualified practitioner. Make sure you press them firmly
on the patient's skin to ensure good conductivity.
4.
Ensure the ultrasound applicator is plugged in.
5.
Depending on the type of waveform you intend to use,
insert the Lead Wire into Channel 1 or both Lead Wire
Connections on the Accessory Panel.
6.
On the Home screen, press the Up and Down Arrow buttons
to highlight Combo.
7.
Press the Enter button.
The Ultrasound parameters screen displays with the Edit
Stim option highlighted.
NOTE: When you are using combination therapy for
Channel 1 (all waveforms except Interferential), you may
only set up electrotherapy for Channel 1. If you want to
use both chan nels of electrotherapy in conjunction with
ultrasound, you must first begin treatment. You may set
up electrotherapy for Channel 2 later in these procedures
(step 21).
8.
Press the Up and Down Arrow buttons to highlight
Waveform.
9.
Press the Enter button.
The Waveform menu displays.
10. Press the Up and Down Arrow buttons to highlight the
appropriate waveform.
11.
Press the Enter button to accept the selection.
The Waveform menu closes.
12. Press the Up and Down Arrow buttons to highlight
Edit Stim.
13. Press the Enter button to accept the selection.
The current waveform's parameters display.
14.
Press the Up and Down Arrow buttons to highlight the
parameter you want to change and adjust it accordingly,
making sure to press the Enter button after each
adjustment.
15. Press Enter to accept the parameters.
The Parameter screen refreshes and the new parameters
are displayed.
16. Press the up and down arrows on the INTENSITY button to
raise or lower the electrotherapy output.
17.
Press the Up and Down Arrow buttons to highlight Edit
Ultrasound.
18. Press the Enter button to accept the selection. The
Ultrasound parameter screen displays.
