Input Options

A range of input options are available for i-digits™ allowing the optimum option for the individual user to be utilized.

LP remote electrodes

Low profile gold domes, conform well to the shaping of the residual hand for improved comfort. Suspension piece is fabricated within the silicone socket. This provides the optimum suspension and spacing of the electrode domes. Two domes are positioned together for the muscle site, and one single shared ground dome can be used for dual site control.
