Introduction
The Nu-Tek Levator Elite combined EMG [electromyography] and
Neuromuscular Stimulation is a simple to use advanced product for reducing
incontinence in females with urinary incontinence. The device has been
developed to enhance and support the Clinician, to assist the end user at
home to learn more about their Pelvic muscle and above all to improve their
Pelvic Muscle strength and their incontinence therapy.
The Nu-Tek Levator Elite: EMG Biofeedback measures the Pelvic contraction,
and assists users to maximise Pelvic oor exercises, after periodic training, it
also helps to assess the pelvic oor muscle condition, quantify the need for
further treatment and evaluate report on the patient’s progress. Muscular
Stimulation improves blood circulation, capillary bed density and strengthens
the Pelvic oor muscles. EMG triggered stimulation facilitate those with
accid muscles; ETS helps reduce the symptoms in Genuine Stress
incontinence in some patient’s and is being used more frequently by
clinicians for this condition
For the end user, in patient mode, a simple and easy to understand EMG
Biofeedback bar graph displays the Nu-Tek pelvic muscle strength
grading on a scale of 1 to 6, and assists the user to meet their pre-set targets.
In the therapy mode, the EMG graph can be changed to a waveform format,
as viewed on the LCD screen of the device or using the Nu-Tek software
link on a desk top or laptop computer . The waveform can be used to
help analyse the patient’s condition. Periodically the doctor or therapist will
be able to download newly developed programs for Muscle Stimulation, EMG
Biofeedback and EMG- TRIGGERED STIMULATION. This helps this unique
product to keep abreast of any clinical trials where the conclusion is that a
specic program or program set may assist in enhancing the treatment of
continence. The Nu-Tek Levator Elite has 3 clinical modes: EMG, ETS, and
STIM. Each of these modes has custom programs. The device also includes
pre-set EMG and STIM programs: there are 20 pre-set Pelvic muscle
stimulation programs: Genuine Stress, Urge, Frequency, weekly maintenance.
Lack of sensation, rectal stimulation and several other Patient conditions. One
pre-set EMG program for assessment. The custom program has a diverse
range of parameters that can be programmed by the patient or therapist to
meet individual user conditions. Any one of the pre-set or custom programs
can also be selected freely by the user. The essential performance of the
device are free from the production of unwanted or excessive stimulation
output and free from the display of incorrect numerical values associated
with measure to be performed.

EMG Work/Rest
The W/R phase consists of Work and Rest periods and repeated Trial times
(repetitions). During the Work period, the patient is prompted to contract
their muscle. During the Rest period, the patient is prompted to relax their
muscles. At the end of the work/rest sessions the EMG values display the
information on the LCD screen of the device. The device can also be linked to
a PC or laptop computer.
Relaxation test:
The ideal resting value when conducting work/rest sessions for improving
the Pelvic Floor Muscle is 4 μV (microvolt). The relaxing value is just as
important as the pelvic oor muscle contracting value. The resting time for
the pelvic oor muscle exercises should be at least 5 seconds and longer, if
the user is unable to contract their pelvic oor muscle above muscle strength
scale 1.
Rapid contractions:
The patient should perform 5 rapid contractions, note how quickly the bar
graph rises and falls. If the contractions and release times are slow, the user
will need to improve their fast twitch muscle bres by conducting quality
Pelvic oor muscle exercises at least once per day or more. If after a few
weeks there is no marked improvement, consider electrical stimulation using
a setting of 35Hz, 220µS Pulse Duration, for 20 -25 minutes per day.
Contract and hold:(Endurance Training)
The patient should contract the pelvic oor muscle for as long as possible, 5
seconds is reasonable, 10 seconds would indicate a strong muscle, any longer
would be excellent.
Work/rest session:
Two basic purposes for Work/Rest session:
1. Enhances Pelvic Floor Muscle exercises for both strengthening and relaxing
the muscles, and to ascertain if other forms of treatment are required.
2. Periodically perform Work/Rest session and note the results, especially the
data of the assessment program. This allows the patient or therapist to see
or analyse muscle improvements, which can be organised or used as a
valuable clinical report.
To run the assessment Work/Rest session:
1. The assessment program ideally should follow the settings: Work Time=5s,
Rest Time=5s, =5s, Threshold=30μV, ABOVE feedback sound, WIDE lter,
Nu-Tek Levator Elite User Manual
Examples of EMG treatment

- Page 16 -
Nu-Tek Levator Elite User Manual
AUTO threshold and 5 Trials. Use the WIDE lter band for continence as the
measurement will be more accurate. When using the electrodes near heart
the proximity of the upper arms, back, etc., use the NARROW lter band
(lters out the unwanted heart beat frequencies).
2. Press the OK button, the initial REST prompt will appear, followed by 5
repetitions (trials) of 5 sec of Work followed by 5 sec of Rest. At the end of
the sessions the user can view the session statistics on screen at the end
of the last Rest period. During the Work period, the patient should contract
the muscle as hard and rmly as possible, ideally during Rest period the
patient should relax as quickly as possible, below 4μV or lower. Suggest to
patient to run the assessment program each week or at another suitable
time.
3. When the device is connected to the PC, the PC Software records the
statistics and stores the information on to the database.

EMG and ETS Threshold
What is EMG THRESHOLD?
Threshold is an EMG value measured in μV (microvolt). For strong muscles
which perform higher EMG biofeedback muscle contractions the threshold
level will be higher than for weak or accid muscles. In ETS mode (EMG
Triggered Stimulation) the patient needs to contract the muscle above the
target threshold to trigger the stimulation.
Auto threshold:
To select Auto threshold of the EMG or ETS parameter setting mode use the
THRS+ or THRS- buttons. Automatic threshold is designed to adjust the EMG
muscle strength scale (and the point of ETS triggering) to the actual level of
the patient’s EMG biofeedback muscle contraction
Auto threshold during EMG session:
Select the EMG mode and press OK to begin the EMG session. Work/Rest
prompts will appear. During each Work period the device measures Work
Average EMG, at the beginning of the next Work period, the threshold is set
at 80% of the previous Work Average. (This functionality is available only for
Auto threshold)
Auto threshold during ETS session:
Select the ETS mode, press mA+ button to start the session. If the target
threshold is reached (EMG will trigger the stimulation) in seconds, the device
will increase the target threshold for the next trial. For example , the work
period is 20 seconds, If the patient reaches the threshold very quickly in
Sector A (1-5s), the next threshold will be calculated as previous threshold
plus 12.5%; if reached the threshold in Sector B(6-10s), as previous threshold
plus 5%, if reached in Sector C(11-15s), as same as the previous threshold. If
the Patient had diculties with triggering from EMG to stimulation in Sector
D(16-20s), or didn’t trigger the stimulation during the Work period, the next
threshold will be reduced by 5%.
MANUAL threshold
At any time when the EMG or ETS is displayed, the threshold can be adjusted
manually by pressing the THRS+ or THRS- buttons.
NOTE! For better control of ETS Score statistics we recommend to use
Manual threshold for ETS session.

EMG in Patient Mode
In the Patient Mode, a simple and easy to understand EMG Biofeedback bar
graph displays the pelvic oor muscle strength and assists the user to meet
their pre-set targets. The bar graph scale on the device is divided between
1- 5, plus 6 as an extra for those people who can contract above the standard
scoring of 5.
Note:
The normal resting muscle tone is 4 Microvolt’s (μV) or lower. Between work/
rest trials it can be for some users a challenge to relax the pelvic oor muscle
as low as 4μV, under 6μV in such circumstances is satisfactory
Muscle Strength Grading Scale (Nu Tek Scale)
