AbstractIn the last couple of years, active development of lower limb orthotic devices has mainly targeted individuals with spinal cord injury or stroke. However, due to the smaller population and lack of support from the wider community, there is a group of minorities in society suffering from poliomyelitis who do not benefit from these new technologies. They have unique gait patterns and rehabilitative needs which are very different from those with stroke or spinal cord injuries. To alleviate their difficulties in ambulation and pain, improving the gait performance of individuals with poliomyelitis through newly designed orthoses would be beneficial, our research team has designed a robotic knee orthosis equipped with an automatic knee-locking and actuating mechanism synchronized to the wearer's gait phase. In order to achieve better sensing accuracy, a 3D printed sensing insole with an optimized pressure-sensing module and a specific sensing logic different from existing orthoses has been introduced to identify foot pressure pattern and gait phase during ambulation. This chapter mainly focuses on how to design an exoskeleton robotic system to assist persons with poliomyelitis and to evaluate the effectiveness of the robotic knee orthosis in both clinical performance and gait analysis. A feasibility test has been carried out to investigate the efficacy of robotic knee orthoses on two subjects. Details of how to carry out the clinical training, controlled design of the robotic knee orthosis, and the results of training subjects are discussed.
