Quick answer: Mulder’s click test is a quick exam for Morton’s neuroma: the examiner squeezes the forefoot side-to-side while pressing between the metatarsal heads, and a palpable or audible click with pain suggests a neuroma. It’s a useful bedside sign, but ultrasound or MRI confirms the diagnosis.

The Mulder’s click test is the in-office maneuver podiatrists use to diagnose Morton’s neuroma — when the click happens, you usually feel exactly the same pain you have been experiencing for months.
You’ve come to the right podiatry team. Dr. Tom Biernacki, DPM, FACFAS — board-certified foot & ankle surgeon with 3,000+ surgeries — explains exactly what the Mulder’s click test for Morton’s neuroma means and what works. Call (810) 206-1402 for same-day appointment at Howell or Bloomfield Hills.
Mulder’s click test is the clinical gold standard for diagnosing Morton’s neuroma — but a positive test doesn’t tell you which treatment you need. A neuroma confirmed by Mulder’s click can range from a 3mm thickening that responds to a corticosteroid injection to a 9mm mass that requires surgical excision, and the size changes the entire treatment path. Most patients with a positive Mulder’s click don’t know which end of that spectrum they’re on. Call (810) 206-1402 — we perform Mulder’s test and ultrasound confirmation on the same visit.

Quick Answer
Mulder’s click test is the #1 physical exam test for diagnosing Morton’s neuroma. Your podiatrist squeezes the forefoot from the sides while pressing upward on the intermetatarsal space. A positive test produces an audible or palpable “click” — the swollen nerve subluxating (popping) between the metatarsal heads — often accompanied by the patient’s typical pain and tingling. The test has a sensitivity of 61–98% and is the fastest, most reliable way to identify a neuroma in the office without imaging.

If you have been dealing with pain, burning, or a strange bunched-up feeling in the ball of your foot, your podiatrist will likely perform Mulder’s click test during your evaluation. Named after Dr. J.D. Mulder, this quick, in-office examination is the gold standard physical exam maneuver for identifying Morton’s neuroma — and it takes less than 30 seconds to perform.
What Is Mulder’s Click Test?
Mulder’s click test (also called the transverse forefoot compression test or Mulder’s sign) is a clinical examination technique specifically designed to detect Morton’s neuroma. When positive, the examiner can feel and often hear the swollen nerve pop (subluxate) between the metatarsal heads as the forefoot is compressed.
The “click” is produced by the thickened nerve displacing from the intermetatarsal space toward the plantar (bottom) surface of the foot when pressure is applied. A normal nerve is too small to produce this sensation — only an enlarged, fibrotic nerve generates the characteristic click. This is what makes the test so specific for Morton’s neuroma.
How the Test Is Performed (Step-by-Step)
The test is painless to set up and takes less than 30 seconds. Here is exactly what your podiatrist will do.
Step 1: You sit or lie down with your foot relaxed. The podiatrist holds the forefoot with one hand wrapped around the metatarsal heads (the widest part of the foot).
Step 2: With the other hand, the podiatrist places a thumb on the plantar (bottom) surface and an index finger on the dorsal (top) surface of the suspect intermetatarsal space — most commonly between the third and fourth metatarsals.
Step 3: The hand wrapped around the forefoot squeezes the metatarsals together (transverse compression) while the other hand simultaneously presses upward from the bottom.
Step 4: If a neuroma is present, the examiner will feel (and sometimes hear) a distinct click or pop as the enlarged nerve subluxates dorsally between the compressed metatarsal heads. The patient typically reports their familiar pain, burning, or tingling at this moment.
A positive Mulder’s click is one of the most satisfying clinical findings in podiatry — both the examiner and patient know immediately what is causing the problem.
What a Positive Mulder’s Click Means
A positive result strongly suggests Morton’s neuroma in the tested intermetatarsal space. The test is considered positive when the examiner palpates the characteristic click AND the patient reports reproduction of their symptoms (pain, burning, tingling, or the feeling of a “bunched-up sock”).
It is important to note that pain alone without the click is not a positive Mulder’s sign — it may indicate metatarsalgia, bursitis, or stress injury instead. The click specifically indicates the presence of a mass (the enlarged nerve) displacing between the metatarsals.
How Accurate Is Mulder’s Click Test?
| Diagnostic Measure | Mulder’s Click Test | Ultrasound | MRI |
|---|---|---|---|
| Sensitivity | 61–98% | 79–95% | 83–93% |
| Specificity | 95–100% | 88–100% | 86–99% |
| Cost | $0 (included in exam) | $200–$500 | $500–$1,500 |
| Time to result | 30 seconds | 15–20 minutes | 30–45 minutes |
| Best use | First-line screening | Confirming size, guiding injections | Ruling out other pathology |
The wide sensitivity range (61–98%) reflects variations in examiner experience and neuroma size. Larger neuromas (>5mm) produce more prominent clicks and higher sensitivity. The specificity is consistently high — when a true click is present, it almost always indicates a neuroma.
Other Physical Tests for Morton’s Neuroma
Sullivan’s Sign (Thumb Index Finger Squeeze Test). The examiner directly compresses the intermetatarsal space from plantar to dorsal. A positive result reproduces the patient’s radiating toe symptoms. This is considered the #2 most useful clinical test after Mulder’s click.
Foot Squeeze Test. The forefoot is compressed side-to-side. A positive result produces pain localized to the suspect intermetatarsal space. Less specific than Mulder’s click because metatarsalgia and bursitis can also produce pain with this maneuver.
Toe tip sensation test. Light touch or pinprick testing of the third and fourth toes. Decreased sensation compared to the unaffected side supports the diagnosis by confirming nerve involvement.
Can You Try Mulder’s Click Test at Home?
You can perform a simplified version at home to get a preliminary idea, though it is not a substitute for professional evaluation.
Sit down and cross the affected foot over your opposite knee. Wrap one hand around the front of your foot (around the metatarsal heads) and squeeze firmly from the sides. With the other hand, press upward on the space between the third and fourth toes from the bottom. If you feel a click or pop accompanied by your typical pain/tingling, that is suggestive of a neuroma.
Even if your home test is positive, see a podiatrist to confirm the diagnosis and rule out other conditions. Several other forefoot problems can mimic Morton’s neuroma symptoms, including stress fractures, metatarsophalangeal joint capsulitis, and intermetatarsal bursitis.
Morton’s Neuroma Treatment Overview
Once diagnosed, Morton’s neuroma treatment follows a stepwise approach starting with the least invasive options.
First line: Offloading. Switch to shoes with a wide toe box and add metatarsal pads positioned just behind the metatarsal heads. This single change resolves symptoms in approximately 40% of patients. The pad spreads the metatarsals apart, decompressing the nerve.
Second line: Orthotics and toe spacers. Custom orthotics with a built-in neuroma accommodation pad provide sustained offloading. Toe spacers (like Correct Toes) worn between the affected toes reduce nerve compression during activity.
Third line: Injection therapy. A corticosteroid injection under ultrasound guidance reduces perineural inflammation and can provide weeks to months of relief. Some podiatrists offer alcohol sclerosing injections — a series of 4–7 injections that chemically shrink the nerve tissue.
Fourth line: Surgery (neurectomy). For the approximately 20% of patients who do not respond to conservative care, surgical removal of the affected nerve segment is effective, with success rates of approximately 85%. Recovery takes 3–4 weeks.

⚠ See a Podiatrist If You Notice
- Forefoot pain or numbness that persists despite wide shoes and metatarsal pads for 4 weeks
- Constant numbness (not just with certain shoes)
- Pain that wakes you at night (unusual for neuroma — rule out other pathology)
- Swelling or visible deformity in the forefoot
- Symptoms worsening despite conservative treatment
- Pain in the ball of the foot following an injury (possible stress fracture)
MOST COMMON MISTAKE WE SEE
Many patients spend months treating ball-of-foot pain as metatarsalgia — padding, wider shoes, metatarsal insoles — when the actual diagnosis is Morton’s neuroma. The key differentiator is symptom character: metatarsalgia is an aching pressure pain, while Morton’s neuroma produces burning, electric, or tingling pain that radiates into the toes. If padding and shoe changes haven’t resolved forefoot pain in 6–8 weeks, ask for a Mulder’s click test. A positive result means steroid injection or radio-frequency ablation, not more padding.
DIFFERENTIAL DIAGNOSIS — CONDITIONS THAT MIMIC MORTON’S NEUROMA
- Metatarsalgia — aching pressure pain under the metatarsal heads; no burning or radiation; Mulder’s test negative; responds to offloading pads
- Plantar plate tear — pain under the 2nd MTP joint; toe floats or deviates; positive drawer test at the 2nd MTP; requires MRI to confirm
- Stress fracture of the metatarsal — focal bone tenderness; pain worsens with activity over weeks; X-ray may be negative early; MRI is definitive
- Intermetatarsal bursitis — similar location to neuroma but Mulder’s test negative; bursa is fluid-filled (ultrasound shows anechoic sac); responds to steroid injection
- Tarsal tunnel syndrome — burning and tingling but in the entire plantar foot, not localized to one web space; positive Tinel’s at the tarsal tunnel
RED FLAGS — SEE A PODIATRIST URGENTLY
- Constant burning pain in the foot even at rest (may indicate tarsal tunnel or vascular cause)
- Numbness or weakness spreading beyond the ball of the foot
- Pain in multiple web spaces simultaneously
- A palpable lump in the foot that is growing rapidly or feels hard
- Symptoms accompanied by skin color changes, temperature differences, or hair loss on the foot (vascular or neurological cause)
- Diabetic patient with any new burning foot pain

Frequently Asked Questions
Does Mulder’s click test hurt?
The test may briefly reproduce your symptoms — a momentary pinch, burn, or tingling — but it is not performed with excessive force. Your podiatrist applies enough pressure to elicit the click and your typical symptoms, then releases. The discomfort lasts only a few seconds and tells both you and the doctor exactly what is causing your foot pain.
Can you have a neuroma without a positive Mulder’s click?
Yes. Small neuromas (under 5mm) may not produce a palpable click even though they are symptomatic. In these cases, ultrasound or MRI can confirm the diagnosis. Conversely, a positive click with reproduction of symptoms is considered highly reliable — further imaging may not even be necessary before starting treatment.
Which intermetatarsal space is most commonly affected?
The third intermetatarsal space (between the third and fourth toes) accounts for approximately 65–70% of Morton’s neuromas. The second intermetatarsal space (between the second and third toes) accounts for most of the remainder. First and fourth space neuromas are rare.
Do I need an MRI if Mulder’s click is positive?
Not necessarily. If the clinical presentation is classic (positive click, typical symptoms, pain relieved by removing shoes) and you respond to initial conservative treatment, imaging is often unnecessary. Your podiatrist may order an ultrasound or MRI if the diagnosis is uncertain, if surgery is being considered, or if there is concern for other pathology like a stress fracture or capsulitis.
The Bottom Line
Mulder’s click test is the fastest, most cost-effective way to diagnose Morton’s neuroma. A positive click combined with reproduction of your symptoms gives your podiatrist a confident diagnosis in under 30 seconds — often without the need for expensive imaging. Once diagnosed, most neuromas respond well to simple conservative measures: wider shoes, metatarsal pads, and toe spacers. If those changes alone don’t resolve your symptoms within 4–6 weeks, a cortisone injection or custom orthotics usually will.
