Solid Ankle Foot Orthoses (AFOs) can be used for both orthopaedic and neuromuscular conditions. A solid AFO is a stiff shell which restricts all movement of the ankle, a bit like a cast that can be taken on/off freely and fits into shoes.
Solid AFOs are used in orthopaedics when an ankle position is collapsing in order to restrict further degradation. They can also be used to reduce pain from severe arthritic changes in the foot and ankle as a non-surgical treatment option when either surgery is not optional or inconvenient at the present time.
The Solid AFO is also used for neuromuscular conditions where a crouched stance is present, often a result of muscle weakness, and are used to create a more upright walking stance and stable base of support.
