| Ease of use The user-friendliness is determined by means of a questionnaire developed in-house and qualitative interviews. Visual Rating Scale Pain Using the visual rating scale, the user should indicate his current pain sensation and, if necessary, correct it independently during testing or later treatment. This is intended to achieve a training adjustment with regard to a movement in the pain-free range. Electronic tracer pen The tracer pen is intended to quantify the effusion in the knee joint and thus allow statements to be made about the state of irritation in the knee joint. EMG Derivation The EMG derivative is used for the detection and control of relaxed, passively working musculature or of protective/defensive voltage or desired active cooperation according to the functional mode of the motor rail. A cable version of an EMG preamplifier is provided. Electronic measuring tape An electronic measuring tape is used to measure swellings in the knee joint area, which determines the circumference at defined anatomical reference points with constant contact pressure. Thermal imaging camera In order to identify a possible overheating of the knee joint as an irritant condition, the temperature should be measured. Since the punctual heat measurement is too variable and therefore cannot be used, a thermal imaging camera is used. The thermal imaging camera allows the imaging of a temperature topography of the entire knee joint. Physiological combined measuring sensor Bioharness The relevance of cardio-vascular parameters for training control is still under discussion. Therefore, the relevance of pulse and derived parameters such as heart rate variability (stress indicator) is further pursued. | — |
