What is the main purpose of an orthotic device?

The main purpose of an orthotic device is to provide support and stabilization to the musculoskeletal system. Orthotics are designed to correct biomechanical issues, relieve pain, improve functionality, and help prevent further injury. By supporting or aligning limbs or joints, orthotics assist individuals in achieving better mobility and overall physical performance.

For example, an ankle-foot orthosis can support a patient with foot drop, enabling them to walk more effectively. This stability can also enhance balance, allowing for safer movement during daily activities.

In contrast, the other options pertain to different functions not associated with orthotic devices. Enhancing visual acuity relates to eyewear or vision aids, while replacing lost limbs would involve prosthetics rather than orthotics. Improving skin hydration is typically addressed through topical treatments or therapies rather than through the use of orthopedic devices.
