A vizsgálatról

Mit akar kideríteni a vizsgálat

Robotic lower limb exoskeletons aim to improve or augment limb functions. Automatic modulation of robotic assistance is very important because it can increase the assistive outcomes and guarantee safety when using exoskeletons.

A teljes eredeti leírásKevesebb

However, this automatic assistance adjustment is challenging due to person-to-person and day-to-day variations, as well as the time-varying complex human-machine-interaction forces. In recent years, human-in-the-loop optimization methods have been investigated to reduce participants' metabolic costs by providing personalized assistance from robotic exoskeletons. However, metabolic cost measure is noisy and the experimental protocol is usually relatively long. In addition, the influence of exoskeleton control on this human state in terms of energetic cost is unclear and indirect. More importantly, the optimization by reducing metabolic cost is found to affect human gait patterns and cause undesired outcomes. In this study, new evaluation measures other than metabolic cost will be investigated to optimize the assistance from a powered hip exoskeleton based on a reinforcement learning method. It is hypothesized that the new reinforcement learning-based optimal control approach will produce personalized torque assistance, reduce human volitional effort, and improve balance and other performance during walking tasks. Both participants without and with neurological disorders will be included in this study.

A vizsgálat 2 csoportja

  • Group A - Participants without neurological disordersA vizsgált kezelés

    Individuals without any neurological disorders will be recruited (Group A). Usually, participants from this group are able to walk normally on different terrains and at multiple typical walking speeds.

    Kezelés: A zero impedance mode, controlling a wearable bilateral hip exoskeleton, A personalized optimal assistance mode, controlling a wearable bilateral hip exoskeleton és A free walking mode, without wearing a wearable bilateral hip exoskeleton

  • Group B - Participants with paretic strokeA vizsgált kezelés

    Individuals with paretic stroke will be recruited (Group S). Usually, participants from this group have limited hip joint motion of range, weakened hip joint flexion or extension, or both flexion and extension functionalities, but they can also walk independently.

    Kezelés: A zero impedance mode, controlling a wearable bilateral hip exoskeleton, A personalized optimal assistance mode, controlling a wearable bilateral hip exoskeleton és A free walking mode, without wearing a wearable bilateral hip exoskeleton
