surface EMGOral Muscular Screening
InnerSmile Pro.Single Track Muscle Scanner
For use in First Visit Evaluation Screening …
The Single Track hand held surface Electro MyoGraphy scanner is a small but very versatile dynamic muscle evaluation device.
It has to be considered the entry level for physiological evaluation of muscle activity as well as muscle training.
Single Track sEMG
Simply plug the unit into the USB port on your computer and hold it on the muscle group you want to evaluate.
No messy gel on the electrodes
Use Alcohol to moisten the contactsand to clean the area on the face to be scanned.
EASY TO USE ON EVERY PATIENT

For The Masticatory Function It Is Important To Evaluate The Following Muscles :
RIGHT MASSETERLEFT MASSETERRIGHT ANT. TEMPORALISLEFT ANT. TEMPORALISUPPER HYOID GROUP
Muscle Relaxation Evaluations:
SPONTANEOUS RELAXATION◦It is the natural perception that the person
has about that muscle
INFORMED RELAXATIONS◦When we give basic information to the person
on what type of “behavior” to assume to allow the muscle to relax
TRAINED DEEP RELAXATION◦When the person has undergone extensive
cognitive training (sEMG Biofeedback), to learn the correct behavior in order to obtain deep muscle relaxation and therefore have the perception of minor muscle tension.
MUSCLE PATTERNS
◦There are 5 elements to the sEMG muscle pattern
◦You need to evaluate this basic sEMG muscle pattern.
MUSCLE PATTERNS
The five elements in the muscle pattern are :
1.Resting Muscle Pattern
2.Contraction Pattern
3.Sustained Contraction Pattern
4.Release Pattern
5.Post-Contraction Pattern
HEALTHY MUSCLE PATTERNS
◦ In the normal pattern you see the muscle at its baseline.
◦ Then contracting and maintaining the tension.
◦ Next the muscle is relaxed with full release and no descent notch noted completely back to baseline

DESCENT NOTCH
Difficult to return to baseline
◦ Next the muscle begins to relax and then stops and starts again, having difficulty fully releasing to the relaxed state.
UNHEALTHY PATTERN “POOR RELEASE”
◦ This is what we refer to as a DESCENT NOTCH in the release or latency to return.
SCAN SIGNALS
sEMG in Microvolts◦ Detects occlusion asymmetry
Mean-Median sEMG in Frequency [Hz]◦ Detects local muscle fatigue
Microbreaks in Responses/min◦ Index of muscle health at rest
•There are 5 Different Graphs In Scanning Data
The Scan Profile takes 3 minutes
•5 Different Graphs To Compare and View
FIRST GRAPH TYPE – EMG

SECOND GRAPH TYPE – THE PAIN LINK
PAIN GRAPHPatients rate their pain level (from 0-
10) in the areas that are scanned.
THIRD GRAPH TYPE –FATIGUE-INVERSION
MEAN AND MEDIAN GRAPH• Mean-Median sEMG in Frequency [Hz]
- Detects local muscle fatigue
But what does that mean?
Example of INVERSION
Inversion or
Local Fatigue
Spectral Mean-Median wave colors INVERT at fatigue point.
FORTH GRAPH TYPE –MICROBREAK
MICRO BREAKS GRAPH• Micro breaks in Responses/min
– This allows you to see if muscles are healthy, if they have split second gaps in contraction that allow blood flow, and sustained endurance.
MICRO BREAKS
Hold in full tension

Technical : Microbreaks are related to Muscle Spindle looping – like an auto-reset on the computer to keep it clear under load.
Healthy Muscles show ‘microbreaks’ –
Split second gaps in contraction that allow blood flow, and sustained endurance.
MICROBREAK
INTERFERENCE GRAPH– This shows if you have good contact
or if you need to reposition the electrode.
FITHTH GRAPH TYPE – INTERFERENCE CHECK
GOOD CONTACT BAD CONTACT
Allows analysis of ‘Fatigue’.ADDING FATIGUE COMPONENT
Spectral Mean-Median wave colors INVERT at fatigue point.
sEMG
Mean/Median
NOTE:
There is no fatigue in this graph – muscle is healthy.
Look at :
sEMG + Mean/Median = IS There FATIGUE ?
Allows analysis of ‘‘Microbreaks’.ADDING FATIGUE COMPONENT
Are there healthy microbreaks?
No – This muscle is fatigued.

Mean/Median
Look at :
sEMG + Microbreak + Mean/Median = Is There TRUE FATIGUE Now?
