Contact your Coapt representative with any questions about myotesting and/or electrode
placement. Coapt is willing and able to assist with placement instruction and suggestion—
these can often be accomplished by submitting socket and/or limb shape images to Coapt.
Assembly Instructions for placing Dome Electrodes into the prosthesis
For more information, see Coapt’s Dome Electrode Handbook (available on the Coapt website)
1.
Push a Dome Electrode through a #4 mounting hole you have made in the prosthesis’ inner socket/liner
interface. Place it so the dome side will make contact with the skin of the user, and the thread is on the
outer side of the socket wall. Ensure the Dome Electrode stud is pushed all the way in the hole.
2.
Place a provided Flat Washer on the threaded side of the Dome Electrode.
3.
Place the ring terminal of a conductor cable on top of the Flat Washer. Same-color conductor cables
should be planned for nearby Dome Electrodes.
4.
If you are “sharing” a Dome Electrode, place the other conductor cable(s) ring terminal(s) (different
color(s)) on this threaded stud. Keep in mind that same-color conductors must NOT share the same
Dome Electrode. Also, make sure the black (ground) connection is connected to its own Dome Electrode.
5.
Place a provided Split Lock Washer on top of the ring terminal(s) of the conductor cable(s).
6.
Place and tighten a provided 4-40 Threaded Nut to secure the assembly. Make sure it is tight enough
that the conductor cable wire cannot be moved side-to-side with your fingers.
7.
Repeat these steps for each Dome Electrode that needs to be connected to a conductor.
8.
Do NOT leave any Coapt EMG wires unconnected.
9.
Do NOT use any liquid thread locker.
10.
Where applicable, trim the excess threaded stud of each Dome Electrode once installed and tightened.
Make sure to smooth, remove, or cover any sharp edges.
