When using LP Remote Electrodes or compact elec-
trodes, the three muscle groups within the hand are:
1. Thenar compartment
2.
Hypothenar compartment
3. Dorsum of the hand
2.1 Wristband componentry
The wristband houses the microprocessor and the batter-
ies unit. It is buckle fastened, designed to fit loosely around
the distal forearm. The flexible covering (bellows) allows
access to wiring during prosthesis assembly. To switch the
device on, press the button and the LED light will illumi-
nate. To switch it off, press the button again and the LED
will light momentarily.
The device label can be found on wristband of device, un-
derneath the battery.
The i-digits device is assembled in combination with a
socket designed for the requirements of the individual user.
2.2 Input options and muscle control sites
i-digits
TM
devices can be controlled using Low Profile (LP)
Remote Electrodes or Force Sensing Resistors (FSRs)
which are all specifically designed for use in i-digits
TM
de-
vices.
LP Remote Electrodes pick up muscle activity from the re-
maining muscles within the residual hand to control the
movements of the digits. LP Remote Electrodes have dome
contacts which can improve comfort to the user.
FSRs rely on physical movements of the residual hand to
press against the FSR to control the digit movements. FSRs
are ideally used in situations where there is a remnant fin-
ger present on the affected hand which can flex and extend.
Do not rely on previous myo-electrical test-
ing.
Use anatomical sites where the electrode
will maintain constant, even contact with
the skin. Avoid placing electrodes near
socket interface trimlines, bony areas, skin
grafts or fatty tissue.
