Leg pain or swelling can be unsettling, especially when you come across medical terms like Homan’s sign while searching for answers. Often mentioned in connection with blood clots, Homan’s sign is one of several physical exam findings that has historically been used to evaluate leg symptoms.
However, understanding what Homan’s sign means, and just as importantly, what it doesn’t mean, is key to making informed decisions about your health. This article explains how Homan’s sign is performed, why it’s no longer relied upon as a diagnostic tool, and how modern providers accurately evaluate conditions like deep vein thrombosis (DVT) today.
What Is Homan’s Sign?
Homan’s sign is a clinical finding sometimes checked during a physical exam when a provider is evaluating leg pain or swelling. It refers to calf pain that occurs when the foot is forcefully flexed upward toward the shin (a motion called dorsiflexion).
Historically, this response was thought to suggest a possible deep vein thrombosis (DVT), a blood clot that forms in a deep vein, usually in the leg. However, modern medicine recognizes that Homan’s sign is unreliable and should never be used as a stand-alone test or diagnosis.
Today, it’s best understood as a historical exam maneuver, not a definitive indicator of a blood clot.
How Is Homan’s Sign Performed?
During a physical exam, a healthcare provider may gently raise the patient’s leg and flex the foot upward. If this movement causes pain or discomfort in the calf, the response is sometimes described as a “positive” Homan’s sign.
Importantly, this maneuver:
- Is quick and noninvasive
- Does not confirm or rule out a blood clot
- Can cause discomfort even in people without DVT
Because many conditions can cause calf pain, the test lacks specificity and accuracy.
Why Do Providers Check Homan’s Sign?
Homan’s sign originates from an era before advanced imaging was widely available. Providers historically used it as one of many clues when evaluating leg symptoms.
In modern practice, a provider might still mention Homan’s sign during an exam, but it is never relied on alone. Instead, it may prompt further evaluation if symptoms or risk factors suggest a clot.
Today, clinical decision-making focuses on:
- Symptom patterns
- Medical history and risk factors
- Objective imaging and testing
Limitations: Why Homan’s Sign Is Not Enough
Homan’s sign is no longer considered a reliable diagnostic tool because:
- Low accuracy: Many people with DVT do not have a positive Homan’s sign
- Poor specificity: Calf pain can be caused by muscle strain, cramping, nerve irritation, or circulation issues
- False reassurance: A negative test can delay proper evaluation
- Risk of harm: Aggressive manipulation of the leg should be avoided when a clot is suspected
For these reasons, professional guidelines do not recommend using Homan’s sign to diagnose or exclude DVT.
How DVT Is Really Evaluated
When a blood clot is suspected, providers use evidence-based diagnostic tools, not physical exam signs alone.
A proper DVT evaluation may include:
- Review of DVT-related symptoms and medical history
- Assessment of risk factors (recent surgery, travel, immobility, prior clots)
- Duplex vein ultrasound, which visualizes blood flow and clot presence
- Additional testing if needed
Ultrasound is the gold standard for evaluating suspected DVT because it is accurate, noninvasive, and widely available.
When to Seek Medical Care
You should seek prompt medical evaluation if you experience:
- Sudden leg swelling (especially in one leg)
- Persistent calf pain or tenderness
- Warmth or redness in the leg
- Skin discoloration
- Pain that worsens when walking or standing
These symptoms do not automatically mean a blood clot is present, but they do warrant professional assessment.
If symptoms are severe, sudden, or accompanied by chest pain or shortness of breath, seek emergency care immediately.
What to Do Instead of Self-Testing for DVT
Because physical signs like Homan’s sign are unreliable, self-testing is not recommended. If you’re concerned about circulation or clot risk, the safest next step is a professional evaluation.

Frequently Asked Questions
It may be mentioned during an exam, but it is not relied upon for diagnosis. Modern imaging has replaced it as a diagnostic tool.
No. A negative Homan’s sign does not rule out a blood clot and should not delay proper evaluation.
A positive response may prompt further testing, but it does not confirm DVT. Imaging is required for diagnosis.
No. Self-testing is not reliable and may provide false reassurance or unnecessary concern.
It refers to calf pain during upward flexion of the foot, but this finding is nonspecific and not diagnostic.
The Moses sign involves calf pain when the muscle is compressed from front to back but not side to side. Like Homan’s sign, it is outdated and unreliable.
