PAULA and MyoBoy® Guide
The testing system you will use to conduct a myoelectric evaluation consists of two parts: a software program called PAULA (Prosthetist’s Assistant for Upper Limb Architecture) and hardware referred to as MyoBoy®. Use the following steps to assemble the computer components, connect the PC to MyoBoy, and launch PAULA
Myo Equipment Crate Contents (3) MyoBoys (3) Laptops (3) Computer power cords (3) Computer mouse
Step 1: Assemble Computers and MyoBoys Each computer; power cord and MyoBoy is labeled with a number; Please only combine equipment with the same numbers 1) Unpack contents of the equipment crate listed above 2) Plug power cord into each computer (Figure 1). Plug power cord into outlet
Figure 1 Figure 2
3) Plug computer mouse into a USB port 4) Turn on the Computer (Figure 2)
Step 2: Connect the laptop to the MyoBoy Hardware Figure 3: MyoBoy components

Step 3: Launch the PAULA Software
1) Turn on the laptop (no password required) 2) Click on the “Ottobock Data Station 6” icon on the desktop (wait for the software to load) 3) Click “New Patient” and enter the information marked with a red asterisk 4) Click “New Job”
5) Click on Upper Limb, then “Transradial” , then PAULA
6) In the box: Un-check “Socket Design” 7) Check the “Myo Training Only” box 8) Click “OK”
9) The “Myo Test” screen will open automatically
10) Turn on the 11) When the MyoBoy is MyoBoy by pressing turned on and correctly the “On” button on connected to the laptop, the front. The light the symbol in the lower bars on the left will right corner of the myotest screen will turn blue; briefly illuminate, and a solid red light will indicating the system is illuminate above the operational. A flashing red on button. A flashing symbol indicates the red light indicates the connection has not been 9 volt battery needs made; recheck the system replacement and all connections
12) Click the “Start” button and electrode signals will now be visible on the MyoTest screen. You may begin your evaluation. Remember: Blue=Flexors and Red=Extensors
If you would like to jump ahead to only playing the game and using the simulation tab, you may skip to the MyoSimulation tab now. However, you would like to use the Virtual Simulation of the componentry, you must fill out the Specification and Component Selection tabs:
13) Click on the “Specification” Tab. Then, fill-out the patient information using the numbers and other information as shown below:
-click “Yes” for co-contraction ability -choose either “man” or “woman” -choose “left” or “right” -click on “Socket” and make any choice in he orange box
14) Now that you’ve set up a mock patient; click on the “Component Selection” Tab. Click on the two electrodes, Click on the 10S4=9E169 wrist, and Click on the SensorHand Speed and choose program 1 from the drop down arrow (if necessary)
(If the patient has a wrist rotator, click on 10S17+13E205 box)
15) Click on the “MyoSimulation” Tab. Then click the “Game” Tab. To start the game, click on the Start button. Practice improving your strength, separation, endurance and coordination with the fish, car, or balloon. Practice with one and two signals. (Be certain the MyoBoy is turned on. It will turn off automatically after 2 mins of no signals)
16) Next click on the “Video Simulation” Tab. Practice with the Virtual Hand. Note the proportional control of opening and closing with the SensorHand Speed Program 1
