    Difficulty lifting the front part of the foot, dragging toes, altered gait

  • Treatment:

    Treating the root cause, physical therapy, braces and splints

What Is Foot Drop?

Have you ever noticed yourself dragging your toes while you walk? This could be a sign of foot drop, also called drop foot, a condition that affects your ability to lift the front part of your foot. Foot drop itself isn't a disease, but rather a symptom of an underlying neurological, muscular, or anatomical problem. It can be temporary or permanent, depending on the cause. Foot drop typically affects one foot, but in some cases, it can impact both feet. If you think you might be struggling with drop foot, our team at PrimeCare is here to help!

What Are the Signs and Symptoms of Drop Foot?

Foot drops often show up through a combination of symptoms that impact your gait (walking pattern) and ability to control your foot. Here are the key signs and symptoms to watch out for:

  • Difficulty Lifting the Forefoot: The most noticeable symptom is the inability to raise the front part of your foot while walking. This can lead to dragging toes - as you walk, the toes on the affected foot may scrape or drag along the ground.
  • Altered Gait: To compensate for the inability to lift your foot, you might:
    1. High-Stepping Gait: You may lift your knee higher than usual with each step to avoid tripping over your toes.
    2. Slapping Gait: The foot might slap down onto the ground with each step due to the difficulty of controlling its movement.
  • Loss of Balance and Increased Risk of Falls: Foot drops can affect your balance and coordination, making you more prone to tripping and falling.
  • Numbness or Tingling: In some cases, depending on the underlying cause, you might experience numbness or tingling sensation in the foot or toes.

What Are the Causes of Foot Drop?

Foot drops can stem from various culprits affecting your nerves, muscles, or the structure of your leg and foot. We’ve provided a breakdown of the common causes:

  • Nerve Injury: This is the most frequent cause of foot drop. The peroneal nerve, responsible for lifting your foot, can be compressed or damaged. This can happen due to:
    1. Injuries like falls, sports accidents, or fractures.
    2. Prolonged squatting or sitting cross-legged.
    3. Diabetes, which can lead to nerve damage.
    4. Surgery on the hip or knee.
  • Muscle Disorders: Muscle weakness involved in lifting the foot can also cause foot drop. Conditions like muscular dystrophy or polio can be responsible.
  • Brain and Spinal Cord Disorders: Stroke, cerebral palsy, multiple sclerosis, or amyotrophic lateral sclerosis (ALS) can affect the signals sent from the brain to the muscles, leading to foot drop.
  • Other Causes: Electrolyte imbalances, tumors, and infections can also contribute to foot drop in some cases.

Foot Drop Risk Factors

While foot drop itself isn't a disease, certain factors can increase your chances of developing it. Here's an overview of common risk factors:

  • Nerve Compression: Activities or conditions that put pressure on the peroneal nerve, responsible for lifting your foot, can raise your risk. This includes:
    1. Sitting cross-legged for extended periods.
    2. Prolonged squatting or kneeling (certain professions like gardeners or construction workers).
    3. Wearing a leg cast, especially one that goes up to your knee.
    4. Diabetes, which can lead to neuropathy (nerve damage).
  • Age: As we age, the risk of nerve damage and certain medical conditions that contribute to foot drop naturally increases.
  • Previous Injuries: Past injuries to the ankle, foot, or spine can increase the risk of nerve damage and subsequent foot drop.
  • Obesity: Excess weight can put additional strain on your nerves and potentially lead to compression and foot drop.
  • Electrolyte Imbalances: In rare cases, imbalances in electrolytes, essential minerals for nerve function, can contribute to foot drop.

How Is Foot Drop Diagnosed?

Foot drop diagnosis often involves a multi-step approach to pinpoint the root cause. Here's what you can expect during the process:

  • Physical Exam: The doctor will observe your gait (walking pattern) and assess muscle strength and sensation in your leg and foot. They'll check for weakness, wasting (atrophy) of muscles, and any numbness.
  • Medical History: Discussing your overall health, recent injuries, and any existing medical conditions can provide valuable clues.

Depending on the initial assessment, additional tests might be recommended:

  • Imaging Tests: X-rays, ultrasounds, or MRIs can help identify ankle or foot bone abnormalities, nerve compression, or tumors.
  • Electrodiagnostic Studies: Electromyography (EMG) measures electrical activity in muscles, while nerve conduction studies assess nerve function. These tests can pinpoint the location and extent of nerve damage.

What Is the Treatment for Foot Drop?

The good news is there are various treatment approaches for foot drop, and the best course of action depends on the underlying cause. Here's an overview of common treatment options:

  • Addressing the Underlying Cause: If a specific condition like nerve compression or a muscular disorder is identified, treating that condition can potentially resolve the foot drop.
  • Supportive Devices, Braces, and Splints: Ankle-foot orthosis (AFO) braces or splints can hold your foot in a lifted position, improving gait and preventing tripping. PrimeCare Orthotics & Prosthetics can create custom-designed orthotics to provide optimal support and comfort.
  • Physical and Occupational Therapy: Exercises to strengthen the muscles responsible for lifting the foot and improve overall balance and coordination are important components of treatment. It’s important to work with a physical therapist who can design a personalized exercise program to meet your specific needs.
  • Functional Electrical Stimulation (FES): In some cases, low-level electrical currents can be used to stimulate the peroneal nerve, helping to lift the foot during walking.
  • Surgery: If conservative measures aren't effective, surgery might be considered. This could involve:
    1. Nerve Decompression: Relieving pressure on a compressed nerve.
    2. Tendon Transfer: Transferring a healthy tendon to assist the weakened muscle responsible for lifting the foot.
    3. Ankle Fusion: In severe cases, permanently fusing the ankle joint to improve stability.

PrimeCare Orthotics & Prosthetics can play a vital role in your foot drop treatment plan by providing braces and other supportive devices. We can also help you navigate the recovery process and ensure you have the support you need to walk with confidence again.

Remember: Early diagnosis and treatment are essential for maximizing recovery potential. If you're experiencing foot drop, be sure to consult a podiatrist to discuss your treatment options.

Can Foot Drop Heal on Its Own?

If you’re struggling, you might wonder if it’s possible to heal foot drop on its own. Whether foot drop improves on its own depends on the underlying cause:

  • Temporary Causes: If the culprit behind your foot drop is temporary, like nerve inflammation from prolonged squatting or a minor pinched nerve, it has a good chance of resolving itself as the nerve heals.
  • Treatment Dependent Improvement: In many cases, foot drop can improve with proper treatment addressing the root cause. For instance, if diabetes is causing nerve damage leading to foot drop, managing your blood sugar levels can potentially help improve nerve function and foot drop.
  • Permanent Foot Drop: Unfortunately, foot drops caused by certain conditions like chronic neurological disorders (ALS, multiple sclerosis) or severe nerve damage might be permanent. However, treatment options like braces and physical therapy can still significantly improve your mobility and gait.
