Which of the following is NOT one of the four aspects of progression in rehab?

• A. Resistance
• B. Complexity
• C. Speed
• D. Endurance progression

Answer: (D)

Progression in rehab is about raising task demands in several dimensions in a controlled way. The main dimensions typically used are increasing the resistance (loading) to build strength, increasing the speed of movement to improve power and neuromuscular control, and increasing the complexity of tasks to challenge coordination and motor control. A fourth dimension often addressed is the overall volume or duration of work to target endurance. Endurance progression isn’t treated as its own separate category in many frameworks; endurance is built by increasing how much work you do within the other dimensions (more reps, longer sets, or longer sessions). So endurance progression isn’t one of the four distinct progression aspects, which is why that option is the correct choice.
