1-10. (canceled)
An EMG Amplifier unit for placement at or in a prosthesis stem, whereby the EMG amplifier unit comprises:
- an enclosure, further comprising an enclosure inner space which is defined by enclosure walls,
- a first input signal contact group with several input signal contacts to connect the EMG amplifier unit with at least a first EMG electrodes pair,
- a second input signal contact group with several input signal contacts to connect the EMG electrode unit with at least a second EMG electrode pair,
- an output signal contact group for either direct or indirect connection of the EMG amplifier unit with a prosthesis control,
- a signal amplifier, and
- a signal processing device,
- further comprising that
- the input signal contacts of the first input signal contact group are at least in electric connection with a signal input of the signal amplifier and the input signal contacts of the second input signal contact group are in electric connection with at least an additional signal input of the amplifier, whereby at least an output signal of the signal amplifier is connected with a signal input of the signal processing device, and
- the signal amplifier and the signal processing device are positioned in the enclosure inner space.
