Which statement best defines a static orthosis?

• A. It has no moving parts and provides support, protection, or correction.
• B. It includes dynamic components to allow movement.
• C. It is designed to immobilize the entire limb.
• D. It is used only for protective padding.

Answer: (A)

Static orthoses are external devices that hold a joint or body segment in a fixed position without any moving parts. They provide stability to protect healing tissues, support function, or help correct alignment by immobilizing the targeted area. Because they lack hinges, springs, or other dynamic components, they don’t permit movement at the treated area, which distinguishes them from dynamic orthoses that are designed to allow controlled motion. While some static orthoses cover larger portions of a limb, their defining feature isn’t the extent of immobilization but the absence of movement within the device. A typical static splint, for example, holds the wrist or finger in a set position to protect and support healing structures.
