For use in first visit evaluation screening

For use in First Visit Evaluation Screening …

Single Track sEMG

  • 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.


Easy to use on every patient

EASY TO USE ON EVERY PATIENT

  • 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 contacts

  • and to clean the area

  • on the face to be

  • scanned.

sEMG EVALUATION AND AWARENESS TRAINING

sEMG SINGLE CHANNEL HAND SCANNER


For the masticatory function it is important to evaluate the following muscles

For The Masticatory Function It Is Important To Evaluate The Following Muscles :

  • RIGHT MASSETER

  • LEFT MASSETER

  • RIGHT ANT. TEMPORALIS

  • LEFT ANT. TEMPORALIS

  • UPPER HYOID GROUP


Muscle relaxation evaluations

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

MUSCLE PATTERNS

  • There are 5 elements to the sEMG muscle pattern

  • You need to evaluate this basic sEMG muscle pattern.


Muscle patterns1

MUSCLE PATTERNS

  • The five elements in the

  • muscle pattern are :

  • Resting Muscle Pattern

  • Contraction Pattern

  • Sustained Contraction Pattern

  • Release Pattern

  • Post-Contraction Pattern


Healthy muscle patterns

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

  • HEALTHY PATTERN

Muscle patterns2

MUSCLE PATTERNS

  • UNHEALTHY PATTERN “POOR RELEASE”

  • In this example you

  • see the muscle at its

  • baseline.

  • Then contracting

  • and maintaining the

  • tension.

Muscle patterns3

MUSCLE PATTERNS

  • UNHEALTHY PATTERN “POOR RELEASE”

  • Next the muscle begins to relax and then stops and starts again, having difficulty fully releasing to the relaxed state.

  • This is what we refer to as a DESCENT NOTCHin 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

Second graph type the pain link

SECOND GRAPH TYPE – THE PAIN LINK

PAIN GRAPH

  • Patients rate their pain level (from 0-10) in the areas that are scanned.


Third graph type fatigue inversion

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

Example of INVERSION

Spectral Mean-Median wave colors INVERT at fatigue point.

Inversion or

Local Fatigue


Forth graph type microbreak

FORTH GRAPH TYPE –MICROBREAK

Hold in full tension

  • 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


Surface emg oral muscular screening

MICROBREAK

Healthy Muscles show ‘microbreaks’ –

Split second gaps in contraction that allow blood flow, and sustained endurance.

Hold in full tension

MICRO BREAKS

Technical : Microbreaks are related to Muscle Spindle looping – like an auto-reset on the computer to keep it clear under load.


Fithth graph type interference check

FITHTH GRAPH TYPE – INTERFERENCE CHECK

  • INTERFERENCE GRAPH

    • This shows if you have good contact or if you need to reposition the electrode.

BAD CONTACT

GOOD CONTACT


Allows analysis of fatigue

Allows analysis of ‘Fatigue’.

ADDING FATIGUE COMPONENT

sEMG

Mean/Median

Spectral Mean-Median wave colors INVERT at fatigue point.

Look at :

sEMG + Mean/Median = IS There FATIGUE ?

NOTE:

There is no fatigue in this graph – muscle is healthy.

Allows analysis of ‘‘Microbreaks’.

ADDING FATIGUE COMPONENT

sEMG

Microbreak

Mean/Median

Are there healthy microbreaks?

No – This muscle is fatigued.

Look at :

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