Vectra® Neo Clinical Therapy System
The Vectra® Neo Clinical Therapy System sEMG + Stim
modality utilizes sEMG biofeedback activity coupled with
triggered electrical muscle stimulation using selected
electrotherapy waveforms for the maximum benefi t in
muscle retraining. The following options are available:
sEMG (Channel 1), sEMG (Channel 2),
sEMG (Channels 1 & 2), sEMG + Stim VMS, and sEMG +
Stim Sym Biphasic.
The Electrical Muscle Stimulation is triggered when the
muscle contraction (sEMG portion of the therapy) reaches
the target, sEMG stops, and the muscle is then electrically
stimulated for the pre-set period. After stimulation, the
patient is given a short rest period and then repeats the
muscle contraction, attempting to reach the target to
again trigger the electrical stimulation. This is repeated
throughout the therapy session.
Session parameters can be stored on a USB storage drive
and accessed on the Home screen under the Patient Data
icon. The sEMG portion of sEMG + Stim modality is used
to force the patient to contract the muscle to a prescribed
target. The data cannot be recorded or stored on the
Patient Data Card or the sEMG Data Card.
NOTE: This section applies when Stimulation Channels
and sEMG module is installed.
Complete the following steps to begin sEMG treatment:
1. Touch the screen to activate the system.
2. Prepare patient and therapy system. Refer to the
PATIENT PREPARATION section on page 38 for
electrode selection, preparing the patient, and
securing electrodes.
3. Select sEMG icon from the Home screen.
4. Select the prescribed channel icon (see previous
for the available choices). The treatment screen will
appear (the screen shown below illustrates the sEMG
Channel 1 selection).
• To set the Target Threshold either Automatically or
Manually, touch the CUSTOMIZE Icon.
• Use the Intensity dial to set therapy intensity:
- Clockwise – Increases Intensity
- Counterclockwise – Decreases Intensity
5. Press Start/Pause button.to begin therapy. Screen
prompts willl appear:
• Contract: Instructs the patient to attempt reaching
the Target Threshold. “Contract” and a green vertical
line appear on the screen, indicating the patient
should attempt to contract the selected muscle(s).
“Contract” remains on the screen until the patient’s
sEMG output reaches the Target Threshold, at which
time Electrical Stimulation is delivered.
• Hold: Instructs the patient to contract the selected
muscle(s). When the Target Threshold is reached,
the “Hold” prompt appears, instructing the patient
to continue to contract the selected muscle(s) until
the pre-set time for the Stimulation ends. A yellow
vertical line appears at the end of the Hold period.
• Relax: Instructs the patient to relax. “Relax” appears,
indicating the patient should relax, stopping the
contraction. Relax continues for the pre-set time.
The cycle repeats when “Contract” re-appears, again
indicating the patient should attempt to contract
the selected muscle(s).
