A dynamic orthotic for radial nerve palsy has what components?

• A. Rigid metal frame and rigid supports
• B. Non-elastic straps only
• C. Elastic bands to pull into finger extension
• D. No mechanical components

Answer: (C)

Dynamic extension for radial nerve palsy relies on elastic bands that pull the fingers into extension. These bands provide a continuous, gentle assist that overcomes the weakness of the finger extensors, helping the patient achieve and maintain finger extension during functional tasks. A rigid metal frame would create a static, non-dynamic support; non-elastic straps can hold but cannot actively extend the fingers; and a design with no mechanical components would offer no assist at all. The elastic bands are what give the device its dynamic, assistive function.
