What is the difference between static and dynamic splinting in rehab?

• A. Dynamic splinting allows motion through springs or elastic components.
• B. Static splinting is used only for lower limbs; dynamic only for upper limbs.
• C. Static splinting uses magnets; dynamic uses hydraulic systems.
• D. Static splinting maintains a fixed joint position to prevent contracture.

Answer: (D)

The key distinction is immobilization versus assisted motion. Static splinting holds the joint in a fixed position to preserve length, stabilize alignment, and prevent contracture during healing or when tissues need protection. Dynamic splinting, by contrast, uses a mechanism such as springs or elastic components to apply a gentle, continuous force that assists movement and gradually increases range of motion. That direct description—holding a joint still to prevent contracture—is why this option is best. Other statements either describe a feature of dynamic splints (springs or elastic components) or introduce elements not defining the difference (like limb location or unusual mechanisms), which don’t capture the core distinction between static and dynamic splinting.
