Motor-Cognitive Interactive Upper Limb Robot Rehabilitation for Post-Stroke Motor Dysfunction

Trial design

Treatments tested in this trial

• Motor-cognitive interactive robot

  Device DeviceA medical device, or sometimes a sham device used for comparison, that is being studied.

  Motor-cognitive interactive robot-assisted training integrates motor and cognitive rehabilitation using an upper limb rehabilitation robot. If patients cannot actively lift the robotic arm, an eye-tracking mode detects movement intention and guides the arm along predefined trajectories, adjusting motor and cognitive loads dynamically. As motor function improves, training shifts to an active mode with increased resistance. Patients complete cognitive tasks before moving the robotic arm, while the system monitors movement parameters and provides real-time feedback. Training consists of 60-minute sessions, five days per week for four weeks. Motor load progresses by increasing robotic arm speed or resistance, while cognitive load advances based on task accuracy, ensuring personalized and adaptive rehabilitation.

• Motor-focused robot

  Device DeviceA medical device, or sometimes a sham device used for comparison, that is being studied.

  Motor-focused robot-assisted training primarily emphasizes motor rehabilitation through the use of an upper limb rehabilitation robot. When patients are unable to actively lift the robotic arm, an eye-tracking mode is employed to guide movements, with adjustments made solely to the motor load. As motor function improves, the training transitions to an active mode, progressively increasing resistance while maintaining a constant, minimal level of cognitive difficulty. Patients are required to complete cognitive tasks before initiating movement of the robotic arm, while the system monitors key movement parameters and provides real-time feedback. Training consists of 60-minute sessions, five days per week for four weeks. Motor load is progressively increased by adjusting the speed or resistance of the robotic arm, while cognitive load remains consistently at the lowest level throughout the training.

• Conventional rehabilitation training

  Behavioral BehavioralAn approach designed to change behavior, lifestyle, or mental health, such as counseling or psychotherapy.

  Conventional rehabilitation training adheres to internationally established guidelines and employs task-oriented approaches tailored to activities of daily living (ADLs). The therapeutic regimen incorporates fundamental motor skill exercises, including but not limited to grasp-and-release maneuvers, targeted reaching, fine motor skill development (e.g., button manipulation, zipper operation), and bilateral coordination tasks (e.g., garment folding, towel wringing). The intervention protocol emphasizes progressive task difficulty and functional task integration, with each session lasting 60 minutes. The treatment schedule consists of daily sessions, five times per week, over a four-week duration.
