Rehabilitation, Mechanism Design
A telescopic knee brace designed to support controlled range-of-motion (RoM) exercises while accurately measuring joint angle during rehabilitation. The device follows the natural kinematics of the knee joint, enabling safe and guided movement without restricting the user's motion path.
The mechanical system is built around a telescopic linkage that adapts to the shifting center of rotation of the knee joint, improving alignment and user comfort compared to conventional fixed-axis braces. An integrated angle measurement mechanism provides real-time feedback, allowing both patients and clinicians to track progress throughout the rehabilitation process.
The design emphasizes wearability, adjustability, and ease of use. Soft interfaces and strap configurations ensure a secure yet comfortable fit, while the modular structure allows quick adaptation to different leg geometries. The system is intended for repeated daily use in both clinical and home environments.
Developed as a patented concept, this project combines biomechanical insight with practical engineering to address a common limitation in rehabilitation devices—accurate motion tracking without compromising natural movement. The result is a functional and user-centered solution that bridges the gap between measurement and mobility support.
Problem
Conventional knee braces used in rehabilitation often rely on simple hinge mechanisms that can measure angle but fail to accommodate the natural translational movement of the knee joint. This leads to poor alignment, discomfort, and difficulty in maintaining a stable fit during exercises.
Need
There is a need for a knee brace that can adapt to the natural motion of the joint while still providing a simple and intuitive way to measure joint angle. The system should improve comfort, maintain alignment, and support consistent use during RoM exercises.
Solution
I developed a telescopic knee brace that allows controlled length variation to better match the natural motion of the knee joint. This approach improves alignment and wearability compared to fixed hinge designs. An integrated colored dial provides a direct and intuitive way to track joint angle, enabling measurable feedback without adding complexity.
