Abstract
An orthosis or prosthesis system comprising at least one orthosis or prosthesis, at least one pair of electrodes for contacting the body of the user of the orthosis or prosthesis in order to capture muscle-related signals, at least one evaluation unit for muscle-related signals captured by the at least one electrode pair, at least one actuator for moving the at least one orthosis or prosthesis, and at least one control unit for controlling the at least one actuator. The at least one electrode pair is designed to capture at least a first muscle-related signal using a first measurement frequency and a second muscle-related signal using a second measurement frequency. The at least one evaluation unit evaluates a phase of the first signal and a phase of the second signal. The muscle-related signals can be bioimpedance signals. The system makes it possible to distinguish between muscle contractions and interfering signals.
