AI and medicine-engineering integration | Embodied intelligent ankle rehabilitation robot

Strokes pose a significant health challenge in an aging society, particularly for patients with mobility difficulties and those bedridden for extended periods. These patients require ongoing and repetitive rehabilitation training to prevent joint contractures and excessive muscle atrophy. A team led by Prof. ZHANG Dan, Chair Professor of Intelligent Robotics and Automation of the PolyU Department of Mechanical Engineering, has developed a first-of-its-kind robot product with three degrees of freedom (3-DoF) to provide comprehensive ankle rehabilitation. By integrating embodied intelligence technology and 3-DoF design, the robot can meet the rehabilitation exercise needs of different patients at different stages of rehabilitation. It uses sensors to track and adjust the ankle position for rehabilitation training and simulates natural movements such as dorsiflexion/plantarflexion, inversion/eversion, and internal/external rotation according to different scenarios. In addition, the robot can collect muscle activity data through electromyography signals, enabling real-time monitoring and adjustment of speed and force to customise training intensity. It also offers both patient-driven active training and robot-driven passive training modes, accommodating the needs of different rehabilitation stages. The team is currently conducting clinical trials in collaboration with Huashan Hospital in Shanghai and plans to apply AI to offer personalised training for patients. This innovation holds significant potential for rehabilitation of the shoulder joint or hand. Learn More: Ankle Joint Rehabilitation Robot
