What is the term for weakness of muscles in the feet and ankles?

  1. Foot Drop

  2. Back Pain

  3. Headache

  4. Knee Sprain

The correct answer is: Foot Drop

Foot Drop is the term for weakness of muscles in the feet and ankles. This condition can result from several underlying causes such as nerve damage, muscle or nerve disorders, and brain or spinal cord injury. Back Pain (B) and Knee Sprain (D) are incorrect because these conditions specifically refer to discomfort or injury in the back and knee respectively and not in the feet and ankles. Headache (C) is also incorrect because this term refers to pain or discomfort in the head, not in the feet and ankles. Therefore, the correct term for weakness in the feet and ankles is Foot Drop (A).
