Foot Drop Symptoms, Steppage Gait & Other Warning Signs

The symptoms of foot drop may occur gradually or appear suddenly, making it difficult to stand, walk, or lift the affected foot. The walking pattern or gait of the person typically changes to compensate for the weakness in the foot muscles.

The symptoms of foot drop vary depending on the type and severity of the underlying condition. A few symptoms and warning signs of foot drop are discussed below.


Symptoms and Signs of Foot Drop

Foot drop causes an abnormal decrease in the extent to which the foot can be lifted off the ground during the swing phase of normal walking.1 The swing phase refers to the part of a walk cycle where the front part of the foot lifts off before the heel presses down for the next step.

A few symptoms and signs of foot drop include:

  • Inability to hold footwear. A feeling of loosening of the footwear may cause discomfort and dragging of the affected foot while walking.2
  • Tripping. Weakness in the muscles of the foot and toes may result in frequent tripping.2,3
  • Falls. It is common to lose balance, stumble, and fall with a foot drop. Falls occur due to the inability to properly lift the front part of the foot and toes while walking.4
  • High steppage gait. This type of walking pattern is characterized by raising the thigh up in an exaggerated fashion, such as in climbing stairs. A high steppage gait is attempted to prevent the toes from abnormally hitting or scraping the floor while walking.1,5
  • Circumduction gait. Sometimes, in order to avoid falls or tripping, a circumduction walking pattern, where the leg remains straight and swings to the side in a semicircle to move forward may be attempted.6
  • Limp foot. The affected foot may flop away from the body. It may also be difficult to climb stairs.
  • Numbness. Loss of sensation may occur on the front and/or outer side of the lower leg, and/or along the upper part of the foot.1

    See Leg Pain and Numbness: What Might These Symptoms Mean?

  • Often unilateral. Foot drop typically affects one foot, especially when caused by a pinched nerve in the lower back or leg.7
  • Decrease in muscle mass. Weakening of the muscles may cause the muscle mass to reduce, especially when foot drop is caused by certain autoimmune conditions, such as multiple sclerosis.4
  • Romberg’s sign. There may be loss of balance while standing without support and with the eyes closed.5

The symptoms of foot drop may be constant or intermittent with periods of normal foot strength in between.

Foot Drop Symptoms Based on Specific Nerve Compression

Foot drop may cause weakness with numbness and/or pain in specific areas of the foot and leg based on the underlying compressed nerve. A few common examples are8:

  • L5 radiculopathy or lumbosacral plexopathy. Foot drop from compression of the L5 nerve root or the group of nerves from the lumbar and sacral spine may cause:
    • Weakness in moving the foot upward or downward at the ankle joint, turning the foot to the outer and/or inner side at the ankle, moving the leg away from the body at the hip, and moving the thigh inward from the hip joint
    • Pain in the lower back that radiates to the leg

  • Common peroneal neuropathy. Foot drop from compression of the common peroneal nerve may cause:
    • Weakness in lifting the ankle joint upward and while turning the foot to the outer side of the ankle
    • Numbness in the front and side of the lower leg and top of the foot
  • Sciatic neuropathy. Foot drop from the compression of the sciatic nerve may cause:
    • Weakness in moving the ankle joint upward or downward, turning the foot to the outer and/or inner side at the ankle, and while bending the knee
    • Pain and/or numbness in the back of the thigh, side of the leg, and upper part of the foot

  • Deep peroneal neuropathy. Foot drop from compression of the deep peroneal nerve may cause:
    • Weakness in lifting the ankle joint upward
    • Numbness in the skin over the web between the first and second toes.

Weakness in most cases is felt more while attempting to lift the foot upward.

Foot drop must be evaluated by a physician to accurately diagnose and treat the underlying cause. Treatment usually helps reduce or resolve the symptoms of foot drop, improving leg function.
