Methods and systems for determining changes in muscle activity patterns based on the optical response of subcutaneous human body structures are presented, along with methods and systems for controlling assistive robotic systems based on the measured muscle activity patterns. Elements of a muscle activity measurement system are mechanically coupled to a wearable structure that fits closely to a portion of the body of a human user. The muscle activity measurement system includes multiple emitters and detectors at different spacing along the skin surface. In some embodiments, the illumination intensity of each measurement channel, the programmable gain of each measurement channel, or both, are calibrated to maximize measurement sensitivity. In some embodiments, optical measurement data is employed to more accurately locate the muscle activity measurement system with respect to the human body. In some embodiments, a muscle activity measurement system tracks changes in muscle structure over time.

A method of estimating muscle fibre architecture for a muscular structure is described. The method comprises receiving a plurality of images that represent the motion of the muscular structure during a motion sequence, receiving an initial model of muscle fibre architecture, receiving a model of mechanical coupling between muscular structure motion and muscle fibres, and generating a joint function using muscular structure motion as represented in the plurality of images, the initial model of muscle fibre architecture, and the model of mechanical coupling. The method further comprises applying an optimisation procedure to optimise the joint function and, from the optimisation procedure, determining a model of muscle fibre architecture consistent with the muscular structure motion indicated in the plurality of images.
