What is the normal range of motion for plantarflexion at the ankle?

• A. 20 degrees
• B. 50 degrees
• C. 15 degrees
• D. 5 degrees

Answer: (B)

The normal range of motion for plantarflexion at the ankle is approximately 50 degrees. This movement is essential for various activities such as walking, running, and jumping, as it allows the foot to point downward and pushes off the ground. The ability to achieve this range of motion is crucial in maintaining proper biomechanics and energy efficiency during physical activities. Understanding the normal range is vital for athletes and individuals in rehabilitation, as limitations in this motion could indicate underlying injuries or issues with the musculoskeletal system. This knowledge enables practitioners to assess and design appropriate training or rehabilitation programs to enhance functional performance.
