How might a rehabilitation plan progress through muscle contraction types?

• A. Start with concentric, then isometric, then eccentric contractions.
• B. Start with eccentric contractions and progress to isometric.
• C. Start with isometric for stability, progress to concentric movements, then introduce controlled eccentric loading for tendon and muscle strength.
• D. Use only isotonic movements throughout rehab.

Answer: (C)

The key idea is aligning exercise types with tissue healing and gradually increasing stress. Starting with isometric contractions helps stabilise the joint and activate the muscle without lengthening or shortening the tissue, providing protection and pain control early in rehab. As tolerance and tissue healing improve, moving to concentric movements builds dynamic strength and control through the joint’s range, without exposing the healing structures to the high tensile demands of lengthening. Only after maintaining strength with concentric work should you introduce controlled eccentric loading. Eccentric exercises place higher tension on muscles and tendons, which is especially effective for tendon and muscle remodeling and strength gains, but they are more demanding and riskier if done too soon. This progression—isometrics first for stability, then concentric for strength, then controlled eccentric loading for tendon and muscle adaptation—follows how tissues tolerate load over time and supports safe, functional recovery.
