Which statement accurately describes the primary purpose of an orthotic?

• A. To cure disease
• B. To replace a limb
• C. To support a weak or deformed body part
• D. To eliminate all movement

Answer: (C)

The key idea is that an orthotic is an external device used to support and stabilize a body part to improve function. Its primary purpose is to support a weak or deformed part, helping with alignment, load distribution, and Pain reduction so daily activities are easier and safer. For example, an ankle–foot orthosis helps control ankle position and prevent foot drop in weakness, a knee brace supports the joint in conditions like osteoarthritis, and a wrist splint protects and rests the hand in carpal tunnel syndrome. Orthotics are not meant to cure disease, replace a limb, or completely eliminate movement; their job is to aid function and stability by supporting the affected area.
