INTRODUCTION For many years, the biomechanical evaluation of prosthetic performance has centred around gait analysis and motion capture. While this provides useful, scientific insights, everyday life is not limited to straight-line, level, steady-state walking. With advancements in portable sensor technology in the last two decades, long-term activity monitoring (AM) has become a more feasible and reliable prospect for accurately representing the real-world walking behaviour of patients. Modern microprocessor knees (MPKs) have begun to have this functionality built into the devices themselves, without the necessity for additional, external hardware.
