Abstract
A method for determining the flexion or extension of a joint of a human or animal subject, comprising: applying a plurality of strain gauges to the joint in a known configuration; applying a first inertial measurement unit, IMU, to each strain gauge; receiving strain data from each of the strain gauges; receiving motion data from each of the IMUs; and calculating the flexion or extension of the joint in dependence on the received strain data, motion data and the configuration of the strain gauges.
Claims17
A method for determining a flexion or extension of a joint of a human or animal subject, comprising:
- applying a medical dressing including a plurality of strain gauges to the joint in a known configuration;
- applying a first inertial measurement unit, IMU, to each strain gauge;
- receiving strain data from each of the strain gauges;
- receiving motion data from each of the IMUs;
- and calculating the flexion or extension of the joint based on the received strain data, the received motion data, and the known configuration of the strain gauges;
- wherein the motion data received from the IMUs is adjusted by disregarding or down-weighting in the calculation of the flexion or extension based on the strain data received from the strain gauges.
A medical dressing comprising:
- a strain gauge configured to determine a strain applied in a first direction to the dressing;
- a first and a second inertial measurement unit, IMUs, the first and second IMUs arranged at opposing ends of the dressing;
- and a controller configured to receive strain data from the strain gauge, receive motion data from the IMUs, calculate a position of a first end of the dressing and a position of a second end of the dressing based on the received motion data, and adjust one or more of the calculated positions based on the received strain data;
- wherein the controller is configured to down-weight or disregard motion data from the IMUs based on the received strain data.
