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)
Measured in EMG Microvolt’s μV
Scale 1
Scale 2
Scale 3
Scale 4
Scale 5
Scale 6
Virtually no muscle contraction and very little microvolt readings
Moderate muscle contraction with increased movement and
microvolt reading and a longer muscle contraction holding time
Firm contraction and improved muscle holding time
Strong contraction with much longer muscle holding time
Robust contraction with greatly improved muscle holding time
Slight muscle contraction with little movement, increase microvolt
reading and a short muscle contraction holding time
