Specific Functions:

1. Support and Stability

When bones, joints, or muscles become unstable due to trauma, surgery, or disease (such as stroke sequelae), orthoses immobilize the joint or limb, reducing abnormal movement and preventing secondary injury. For example, ankle-foot orthoses can help patients with foot drop maintain a normal gait.

2. Correct Deformities

For structural abnormalities such as congenital clubfoot and bowed legs, orthoses gradually adjust bone alignment through continuous, gentle mechanical action. They are particularly suitable for children during their early stages of bone plasticity.

3. Pain and Load Relief

For patients with osteoarthritis or meniscus injuries, wearing knee orthoses can distribute joint pressure, reducing pain caused by wear and inflammation.

4. Assist Functional Recovery

For patients with neurological damage (such as spinal cord injury) or postoperative rehabilitation, orthoses can compensate for muscle weakness, help patients regain standing or walking, and promote motor function restoration.
