Which of the following best describes splinting in a medical context?

In a medical context, splinting best refers to muscle rigidity caused by pain. This phenomenon often occurs as the body’s protective response to injury or trauma. When a muscle or joint is injured, the brain sends signals to the body to restrict movement in the affected area to prevent further damage. This involuntary response results in stiffness and tightness of the muscles surrounding the injury, known as splinting.

This concept is particularly relevant in scenarios involving fractures or musculoskeletal injuries, where the body instinctively tries to stabilize the area to reduce pain and protect the injury. The other choices, while related to injuries, do not accurately encompass the definition of splinting. Healing of a fracture refers to the physiological process of bone repair, movement of a joint focuses on the functionality within the body, and laxity of ligaments describes a lack of stability rather than a protective muscle response.
