2.1 Control Sites
One option for control of the i-limb ultra revolution is electrodes.
There are two electrode options available for use with the i-limb
ultra revolution, compact electrodes (g. 1) or remote electrodes
(g. 2). For information regarding the tting of the Touch Bionics
Electrode, review the manual provided with the electrode.
Electrode Site Selection
The use of virtu-limb, the Touch Bionics’ myotesting system, is
recommended to determine the optimal placement of electrodes
(g. 3).
Consult Touch Bionics training materials for information on myo-
testing or section 6 of this manual for information on myotesting
within biosim.
2.2 Socket Fabrication
While fabricating the socket for the i-limb ultra revolution, special
considerations will need to be given to:
1. Battery placement, size and conguration
2. Electrode position or other control method
3. Charge port placement
4. Socket length and the overall length of the prosthesis in
comparison to the opposite side.
Clinicians should have prior experience with building externally
powered prosthetic sockets before tting the i-limb ultra revolution.
Touch Bionics’ batteries, charger port and switch block components
should always be used with the i-limb ultra revolution.
Do not rely on previous myoelectrical testing.
Use anatomical sites where the electrode will
maintain constant, even contact with the skin. Avoid
placing electrodes near socket interface trim lines,
bony areas, skin grafts or fatty tissue.
