Sample BioPAK Recording Protocol
Getting Started
Open BioPAK and click on the first icon and “Add Patient.” Add Name, Date of Birth, and Gender of the
patient. Patient ID # is optional. Select OK and proceed to the record mode
1. JVA Quick (EVERY PATIENT)
A. JVA Quick
-Place the headset on the patient (and amp box around patient’s neck) Make sure the red light is
on the box (Green light if JVA-USB)
-Measure the patients Range of Motion
-Note any significant deflections (not deviations)
-Click on the JVA Quick Preset
-Do a practice run with the patient
-Instruct patient to follow the metronome, open (Wide-Tap..) and close with a light Tooth
Contact
-Enter the Range of Motion and Deflection
-Remember the recording will begin after you enter the Deflection
-Begin Recording by selecting OK
-Determine if patient followed metronome. If yes, save the Trace as a JVA Quick

2. EMG (muscles)
A. Resting EMG
-Instruct the patient not to wear makeup/shave if possible
-Clean the skin thoroughly with alcohol (let the skin dry)
-Carefully place EMG electrodes and Ground and connect wires to electrodes
-Switch the amp box so that the light is Green
-Change ALL EMG presets to 30 seconds (Except Resting)
-Turn off lights and instruct the patient to “Close their eyes and Relax”
-Have the patient sit up with feet flat on the floor and close their eyes
-Select the Resting EMG Preset (Recording starts automatically)
-Press “Pause” halfway through the trace
-Have the stand up and resume
-Save the trace as a Resting EMG
B. Clenching EMG
-Press the Clench Preset
-Have the patient clench HARD (on their back teeth) 3x on natural dentition
-(Clenches should last about 2 seconds)
-Press Pause and insert cotton rolls on Anterior
-Resume, record 3 clenches with the cotton rolls in place
-Press Pause
- Repeat with cotton rolls on Posterior
-Save Trace as Clench
C. Swallow
-Press the Swallow Preset
-Have the Patient swallow 2x (Give them water if necessary)
-Save the trace as Swallow

3. Jaw Tracking
A. Range of Motion
-Dry the lower labial gums of the patient
-Place the magnet on the patient (make sure the line on the magnet is on the patient’s LEFT)
-Make sure that the magnet is straight and does not touch the upper teeth
-Place the JT array on the patient (align with the Magnet Positioner pointer 5-10mm away from
the magnet)
-Check to make sure the JT is aligned properly (Look from the frontal view to make sure distance
in between cheeks is relatively similar, From the Side that it is parallel to the floor)
-Check the Numeric Grid on the JT to make sure that the numbers are somewhat similar
-Click the ROM preset
-Have the patient bite lightly on their back teeth
-Do a practice trace (have the patient open and close 3x to make sure there is no false deflection
in the frontal view) Accept. If it looks good discard the practice trace. If not, re-adjust the
alignment of the sensor array
-Click on Start, Have the patient bite lightly on their back teeth and press OK
-Instruct the patient to Open as wide as possible, close, do a L lateral, R lateral, and protrude
-Accept
-Save as ROM
B. Velocity
-Press the Velocity Preset
-Have the patient bite on their back teeth
-Instruct the patient to OPEN WIDE, CLOSE FAST (3-5 times)
-Save as Velocity or Open wide, close fast
C. Freeway Space
-Press the JT/Tens Preset (or Freeway Space if you wish to record EMG’s too)
-Have the patient lick their lips and relax
-Watch for stable rest position, when satisfied
-Instruct the Patient to Swallow, relax, Tap 3x, and Protrude, Accept
-Save as Freeway Space or JT/Tens
D. JVA/JT
-Place the JVA Headset over the JT Make sure the JVA headset does not touch the JT array!
-Select JVA/JT Preset
3
-Have the patient bite on their back teeth, Click on OK
-Tell them to open and close in sync with the metronome
-When the screen has filled up with data, click Accept
-Save as JVA/JT
-Remove the JT and magnet
4. T-scan/EMG link
-Make sure the patient is entered into the T-scan program
-Condition the sensor, make sure the Center of Force icon is consistent
-Take a recording in Centric Occlusion
-Take a recording doing a Right Lateral
-Take a recording doing a Left Lateral
- Take a recording doing a Protrusive
-Save them respectively
5. Mastication
-Mastication is done with the JT (with an option for the EMG)
-Click on the Mastication Preset
-Give the patient a piece of gum to soften
-Instruct the patient that they will only be able to chew on one side at a time
-Designate a side for them to chew
-Click OK and record about 20 chewing cycles, Accept
-Repeat the other side
4
-Repeat the above process with licorice and beef jerky

The following is the “My Grandfather” Passage:
This paragraph contains all of the sounds (phonetics) of the English language in all of the various positions within
words (beginning, middle, end). It should be read out loud as if being read to someone.
“You wish to know all about my grandfather.
Well, he is nearly 93 years old, yet he still thinks as swiftly as ever.
He dresses himself in an old black frock coat, usually several buttons missing.
A long beard clings to his chin, giving those who observe him a pronounced feeling of the utmost respect.
When he speaks, his voice is just a bit cracked and quivers a bit.
Twice each day he plays skillfully and with zest upon a small organ.
Except in the winter, when the snow or ice prevents, he slowly takes a short walk in the open air each day.
We have often urged him to walk more and smoke less, but he always answers, "Banana oil!"
Grandfather likes to be modern in his language.”
