5
5 Robotic Arm Digital Control (Feedback): (sensor) Input (sensor) Process (decision) Output (motor) Loop (repeat) For Brain Injury: Stroke Functions: A. Compensation B. Training
6
6 A. Compensation Performance↑ ex: reaching, feeding...
7
7 B. Training Passive: Passive:↓Limitation Active (Robotic Therapy) : Active (Robotic Therapy) :↑Recovery
8
8 B. Training - Passive Maintain Functional ROM, ↓ stiffness ex: Continuous Passive Motion (CPM)
9
9 B. Training – Active (1) with resistance Strength, Endurance↑ ROM, Velocity↑ Unicycle Two-Link Arm (UTLA) Northwestern University Mechanical Engineering Dept. Laboratory for Intelligent Mechanical Systems Kinematic Constraints
10
10 B. Training – Active (2) With Target Motor control↑

12 Virtual Reality (VR)
13
13 Virtual Reality (VR) Combined technologies: Motion Analysis & Motion Capture 3D Model IT (Bio-)mechanics For therapy: Medicine, rehabilitation, exercise science...
14
14 Virtual Reality (VR) A. Virtual Environment: vision + audition + (olfaction, temperature, tactile, vestibular...) vision + audition + (olfaction, temperature, tactile, vestibular...) B. Reality Motion (virtual manipulate) role play, motion capture role play, motion capture feedback → virtual environment feedback → virtual environmentTypes: Open VR Close VR
