2.1 Wristband componentry
The wristband houses the microprocessor and the batter-
ies unit. It is buckle fastened, designed to fit loosely around
the forearm. To switch the device on, press the button and
the LED light will illuminate. To switch it off, press the but-
ton again and the LED will light momentarily.
The wristband is designed to fit loosely around the forearm.
It is not designed to be used for suspension of the prosthe-
sis or to hold electrodes in position against the skin.
2.2 Controlling your prosthesis
To fit i-digits™ a socket interface has been specially cre-
ated by your prosthetist team. They will have made this to
ensure it is comfortable and fits directly to your residual
hand. You may experience some minor redness on your
residual hand but this should not last very long after you
remove the device. If the device is causing you discomfort
or affecting you using your i-digits™ then we recommend
that you contact your clinician.
As part of the fitting process, your prosthetist selected
the best method for you to provide control of your device.
This communicates to the processor whether you want
i-digits™ device to open or close. The most common input
type is called an electrode. Electrodes pick up on the elec-
trical activity that your body gives off when you contract
a muscle. While gaining good control may take time and
practice, your method of input should not cause pain. Talk
with your prosthetist if you do not understand how your
input control is working or if it is causing discomfort.
