Differential and Variable Stiffness Orthosis Design with Adjustment Methods, Monitoring, and Intelligence
Description
Upper- or lower-extremity orthoses, including ankle foot orthoses (AFOs), are commonly prescribed for individuals with impairment from stroke, incomplete spinal cord injury, and cerebral palsy. This system is a novel orthosis design and method for improving function with differential and/or variable stiffness via manual, automated, or passive mechanical adjustment.
