Progression in rehab follows the SAID principle which states the body adapts in specific ways to implied demands. This is known as the:

• A. SAID principle
• B. Law of diminishing returns
• C. Hormesis
• D. Tissue remodeling

Answer: (A)

The main idea is that the body adapts in a task-specific way to the exact demands placed on it. In rehab, you design progression by increasing the specific stresses that mirror the patient’s functional tasks—load, speed, range, and control—so the tissues adapt where they are stressed. This targeted, imposed-demand approach is why the term SAID is used: Specific Adaptation to Imposed Demands. For example, if the goal is to improve squat-based knee and hip function, you progressively load those patterns with appropriate resistance and ROM, prompting adaptations in the same tissues and movement patterns used in daily activity. The other options describe different concepts (diminishing returns, hormesis, or general tissue remodeling) that don’t capture this specificity of adaptation to the demanded tasks.
