Which factor best describes why static splinting is used in preventing contractures?

• A. By maintaining a fixed joint position to prevent contracture.
• B. By promoting dynamic motion through elastic components.
• C. By heating the joint to increase extensibility.
• D. By delivering electrical stimulation to the joint.

Answer: (A)

Static splinting works to prevent contractures by holding a joint in a fixed, lengthened position, which keeps the surrounding soft tissues—muscles, tendons, ligaments, and joint capsules—from shortening over time. When a limb is immobilized or kept in a shortened posture, collagen fibers reorient and shorten, leading to a contracture and reduced range of motion. By maintaining the joint at a carefully chosen angle and leaving it in that position for extended periods, the splint preserves tissue length and soft tissue lengthening, making future movement easier and reducing stiffness. This approach contrasts with methods that promote movement through dynamic components, or modalities like heating or electrical stimulation, which aren’t how a static splint prevents contractures.
