What is the principle of progressive loading in rehabilitation of soft tissue injuries?

• A. Begin with high-load, rapid progression and return to activity quickly.
• B. Begin with low-load, pain-free activity and gradually increase intensity and duration.
• C. Avoid loading altogether until fully healed.
• D. Start with pain-induced activity.

Answer: (B)

Progressive loading in soft tissue rehab means starting with low-load, pain-free activity and gradually increasing the intensity and duration of loading as the tissue tolerates it. This approach uses controlled, graded stress to stimulate collagen production and proper fiber alignment without causing further damage. Early on, stay within pain-free limits to preserve range of motion and prevent stiffness, then progressively add resistance, time under load, and task complexity as healing allows. The goal is to stay within the tissue’s tolerance while promoting remodeling and strength that are specific to function or sport. Starting with high-load, avoiding loading altogether, or using pain-driven activity can hinder healing or increase risk, so the best path is a measured, gradual increase in loading while monitoring pain and function.
