The present disclosure describes a measurement unit (13) comprising measurement electronics (51), a wireless transceiver unit (54), and a processing unit (53). The measurement electronics (51) are configured to measure an EMG signal and a motion signal from a limb of a person. The processing unit (53) is configured to determine a principal component representation of the EMG signal and the motion signal in real time, wherein the principal component representation represents a projection of at least one feature of the EMG signal and at least one feature of the motion signal into at least one uncorrelated feature in a feature space formed by orthogonal basis vectors, and transmit the principal component representation to an external system with the wireless transceiver unit.
