Which statement about serial static orthotics is true?

• A. They provide dynamic motion
• B. They apply constant force
• C. They allow gradual increase in range of motion with sequential adjustments
• D. They are used only for cosmetic purposes

Answer: (C)

Serial static orthotics work by holding a joint in a fixed position and gradually increasing that position in small steps over time. This creates a prolonged, low-load stretch on the soft tissues, allowing them to adapt through tissue creep and remodeling. Each adjustment extends the available range a bit more, so you gain motion gradually rather than all at once. That’s why the statement describing a gradual increase in range of motion with sequential adjustments is true. These devices aren’t about dynamic movement—they don’t deliver active motion—and they’re not used for cosmetic purposes. They also don’t rely on a single constant force; instead, they provide a steady, low-stress hold that’s incrementally deepened as the angle is adjusted.
