Which splint is adjustable and applies a pull at 90 degrees?

• A. static progressive splints
• B. dynamic splints
• C. serial static splints
• D. resting hand splint

Answer: (A)

Static progressive splints are designed to lengthen contracted soft tissue by applying a static, sustained pull that you can adjust. The joint is held in a stretch, and as range improves, you increase the angle or reposition the strap to apply a new, greater stretch. Starting around 90 degrees is common because it places the tissue in a favorable length-tension relationship for gradual remodeling without risking overstretch. This combination of a sustained, adjustable pull and static hold distinguishes them from dynamic splints (which provide continuous movement), resting hand splints (which don’t apply a directed pull), and serial static splints (which require changing the position by fabricating a new splint rather than adjusting the existing one).
