What characterizes a Grade II muscle strain?

• A. Mild fibre stretching with local tenderness, healing 1-3 weeks.
• B. Partial tearing of fibres, healing in 4 to 8 weeks.
• C. Complete rupture, recovery 3 months or more.
• D. Local contusion with swelling.

Answer: (B)

A Grade II muscle strain means partial tearing of muscle fibers. This level of damage is more than a light overstretch but not a complete rupture. You’ll usually notice more intense pain, swelling, and weakness with some loss of strength and range of motion. The injury heals longer than a mild strain—typically around 4 to 8 weeks with appropriate rehab. For contrast, a mild overstretch (Grade I) causes less pain and a shorter recovery (about 1–3 weeks), a complete rupture (Grade III) involves a full tear with much longer recovery and often significant loss of function, and a local contusion is a bruise from impact rather than a muscle fiber tear.
