Foot-Drop Plexopathy Symptoms

A person who has a difficult time lifting the front part of her foot may have foot-drop plexopathy. Also known as drop foot, the condition causes a person to drag the front of her foot when walking. According to the Mayo Clinic's website, the condition is a sign of an underlying neurological, muscular or anatomical problem. The condition may be temporary, but in some cases foot-drop plexopathy is permanent.

Symptoms

• According to the Mayo Clinic, foot-drop plexopathy may be associated with only one symptom: difficulty lifting the front part of the foot. Those diagnosed with the condition may drag their foot on the floor as they walk. Pain, weakness or numbness in the foot is a sign of foot-drop plexopathy. Slapping the foot down on the floor or raising the thigh while walking are also symptoms associated with the condition.

Testing

• Foot-drop plexopathy typically affects only one foot. However, the condition may affect both feet, according to the website of the National Institute of Neurological Disorders. The condition is usually diagnosed during a physical exam. In some cases, additional testing may be recommended. Using a magnetic field and radio waves, a magnetic resonance imaging test, or MRI, may be used for a definitive diagnosis. Electromyography, or EMG, may be utilized to measure electrical activity in the muscles and nerves.

Treatment

• A person who suffers from foot drop-plexopathy may have to wear a brace on the ankle or foot, to keep the foot in a normal position. According to the National Institute of Neurological Disorders, shoe inserts may also bring relief. Physical therapy is sometimes used to strengthen leg muscles and help maintain a range of motion. In cases of foot-drop plexopathy associated with a stroke, nerve stimulation may be used to improve the condition. When foot-drop plexopathy is permanent, surgery may improve walking ability. During the surgery, ankle or foot bones may be fused together. Tendons may also be transferred to stronger leg muscles to lessen the characteristics associated with foot-drop plexopathy.

Causes

• Weakness or paralysis of the muscles below the knee may result in foot-drop plexopathy. In some cases, nerve damage during hip or knee replacement surgery can lead to the condition, according to the Mayo Clinic. Muscular dystrophy may contribute to foot-drop plexopathy. Disorders that affect the spinal cord or brain may also cause foot-drop plexopathy. Those disorders may include ALS, multiple sclerosis or stroke.

When to Call

• If you cannot lift your foot, call your doctor. Also, if you drag your foot when you walk, contact your health-care professional. According to the National Institute of Neurological Disorders, a diagnosis of foot-drop plexopathy does not shorten life expectancy.
