Elastic Barrier describes the range between which barriers?

• A. range between physiological and anatomic barrier
• B. a factor that restricts or limits motion
• C. tenderness as barrier
• D. increased muscle tone

Answer: (A)

The elastic barrier is the part of joint motion that lies between the physiological barrier and the anatomic barrier. It’s where the soft tissues stretch elastically and still allow movement, with increasing resistance, before you reach the final end range defined by bone contact at the anatomic barrier. In other words, motion within this zone is possible and reversible, but moving beyond it approaches the end of motion set by the anatomic barrier.
