How long does the proliferation phase last in skeletal muscle healing?

• A. Immediately
• B. 1-6 weeks
• C. Several months
• D. 4-6 weeks

Answer: (B)

The proliferation phase of skeletal muscle healing typically lasts from 1 to 6 weeks following an injury. This phase is characterized by the formation of new tissues, specifically through the processes of cellular proliferation and the synthesis of extracellular matrix. During this time, the muscle fibers begin to regenerate, and scar tissue forms to help stabilize the area while the muscle heals. In the context of skeletal muscle recovery, this phase is crucial because it marks the transition from initial injury management (inflammation) to actual tissue repair. Understanding the time frame of this phase helps clinicians design appropriate rehabilitation strategies. A well-structured rehabilitation program takes into account the duration of the proliferation phase to optimize recovery and restore function without risking re-injury. While there are variations in individual healing times based on factors such as the extent of the injury and the overall health of the individual, 1 to 6 weeks is generally accepted as the standard duration for this phase in skeletal muscle healing.
