Orthoses or orthotic devices help support weakened muscles or joints and assist mobility and correct deformity.
The joint of this type of orthotic bracing acts as the ankle joint and thus helps the leg to perform the actions just as a good ankle would do.
The length of the ankle can go as high as the knee without covering it depending on the requirements.
In adults, the knee orthoses are usually worn to support the knee by stabilizing the patella, help treat injured anterior or posterior cruciate ligaments along with collateral ligaments, and aiding osteoarthritis and rheumatoid arthritis treatment.
Elbow Wrist Hand Finger Orthosis (EWHFO)This type of orthosis is designed for the arm and assists individuals with difficulty in arm movement due to serious conditions like cerebral palsy, spinal injury, brain injury, stroke, and multiple sclerosis.
Also, even if the wrist is encompassed by the brace, you can still use your hand and move your fingers.
