Numbness, tingling, burning, or weakness in the foot and ankle can stem from a many neurological conditions — from peripheral neuropathy and tarsal tunnel syndrome to lumbar radiculopathy and motor neuron disease. Nerve conduction studies (NCS) and electromyography (EMG) are the definitive electrodiagnostic tools that precisely localize nerve dysfunction, distinguish axonal from demyelinating pathology, and guide treatment decisions. This guide explains what these tests measure, what they reveal, and how your podiatrist uses the results.
What Are Nerve Conduction Studies?
Nerve conduction studies measure the speed and amplitude of electrical signals traveling along peripheral nerves. A technician places surface electrodes on the skin over a nerve and delivers a small electrical stimulus, recording how fast the signal travels (conduction velocity) and how large the response is (amplitude). In the foot and ankle, the most commonly studied nerves include:
- Sural nerve: Sensory nerve running along the lateral foot — frequently abnormal in peripheral neuropathy
- Superficial peroneal nerve: Sensory nerve supplying the dorsum of the foot
- Medial and lateral plantar nerves: Terminal branches of the posterior tibial nerve — tested in tarsal tunnel syndrome evaluation
- Deep peroneal nerve: Motor nerve supplying the extensor digitorum brevis — key in anterior compartment pathology
- Tibial nerve: Motor and sensory nerve assessed at the ankle and below in tarsal tunnel evaluation
What Is Electromyography (EMG)?
EMG uses a thin needle electrode inserted directly into muscle to record electrical activity at rest and during voluntary contraction. While NCS assesses the nerve itself, EMG evaluates the muscle’s response to its nerve supply — distinguishing myopathic from neuropathic changes and localizing the level of nerve injury.
Key findings on EMG include fibrillation potentials (spontaneous muscle fiber discharges indicating denervation), positive sharp waves (another sign of acute denervation), reduced recruitment of motor units (nerve or muscle disease), and polyphasic potentials (reinnervation after nerve injury). Together, NCS and EMG provide a thorough picture of the neuromuscular axis from the spinal cord to the muscle fiber.
Common Foot and Ankle Conditions Evaluated by NCS/EMG
Peripheral Neuropathy
Peripheral neuropathy — most commonly from diabetes, but also from alcohol, chemotherapy, vitamin B12 deficiency, and hereditary causes — produces a characteristic “length-dependent” pattern on NCS, with the longest nerves (sural, peroneal) affected first. Reduced amplitudes suggest axonal loss (more severe), while slowed conduction velocities suggest demyelination (more treatable). This distinction directly influences prognosis and treatment choice.
Tarsal Tunnel Syndrome
Tarsal tunnel syndrome — compression of the posterior tibial nerve behind the medial malleolus — may show prolonged distal latencies of the medial and lateral plantar nerves on NCS, though sensitivity is only 40–60%. A normal study does not exclude the diagnosis; clinical correlation remains essential.
Common Peroneal Nerve Palsy
Compression of the common peroneal nerve at the fibular head produces a characteristic pattern: slowed conduction velocity across the fibular head, reduced peroneal motor amplitude, and denervation changes in the tibialis anterior and peroneal muscles on EMG — but normal tibial NCS and normal proximal muscle function.
Lumbar Radiculopathy vs. Peripheral Neuropathy
When patients present with foot pain, numbness, or weakness, distinguishing a spinal cause (L4-S1 radiculopathy) from a peripheral nerve problem is critical. EMG of the paraspinal muscles and comparison of multiple root distributions helps distinguish these entities — an important decision for determining whether spine or foot surgery is appropriate.
Morton’s Neuroma vs. Tarsal Tunnel
While Morton’s neuroma is primarily a clinical and ultrasound diagnosis, NCS/EMG helps exclude more proximal nerve pathology contributing to interdigital pain patterns.
What to Expect During Testing
NCS involves brief electrical stimuli that feel like mild snapping sensations — mildly uncomfortable but not painful for most patients. EMG involves needle insertion into several muscles, producing brief discomfort that resolves immediately on needle removal. The full test typically takes 45–90 minutes depending on how many nerves and muscles are studied. Results are interpreted by a physician trained in electrodiagnostic medicine (physiatrist, neurologist, or specially trained podiatrist) and correlated with clinical history and examination findings.
How Dr. Biernacki Uses Electrodiagnostic Results
At Balance Foot & Ankle, electrodiagnostic findings are integrated with clinical examination, diagnostic imaging (X-ray, MRI, ultrasound), and laboratory data to build a precise diagnosis. For peripheral neuropathy patients, NCS results guide the intensity of preventive foot care, orthotic prescription, and referral for metabolic management. For tarsal tunnel cases, NCS findings influence the decision between conservative care and surgical decompression. For drop foot presentations, EMG localization determines whether podiatric surgical correction, nerve repair, or AFO bracing is the optimal path.

In Our Clinic
Diabetic neuropathy patients in our clinic often don’t realize they have it until we put a 10-gram Semmes-Weinstein monofilament to the plantar foot and they can’t feel it. Many arrive for an unrelated concern — an ingrown toenail, a callus — and we catch the neuropathy on screening. The conversation then shifts: we need to discuss daily foot inspections, appropriate footwear, the urgency of any blister or open area, and the timing of vascular referral if pulses are diminished. Comprehensive diabetic foot exams are covered by Medicare annually. If you have diabetes, we want to see you once a year even if nothing hurts.

Frequently Asked Questions
When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
What is Neuropathy?
Neuropathy is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of neuropathy include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of neuropathy respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from neuropathy varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
