Vascular Testing in Houston, TX
Healthy circulation is fundamental to healthy feet. At In Motion Foot & Ankle, we offer in-office vascular testing to evaluate blood flow through the arteries and veins of the lower extremities. This non-invasive diagnostic service is a critical component of care for patients with diabetes, peripheral artery disease, chronic wounds, or any condition in which compromised circulation may be contributing to pain, slow healing, or increased risk of serious complications.
Why Circulation Matters for Foot Health
The feet are located at the farthest point from the heart, which means they are the first to suffer when circulation is compromised. Reduced blood flow to the lower extremities deprives tissues of the oxygen and nutrients they need to function normally and repair themselves after injury. For patients with conditions like diabetes or peripheral artery disease (PAD), this circulatory deficit can have serious and wide-ranging consequences.
Poor lower extremity circulation is associated with a range of problems including slow-healing or non-healing wounds, increased infection risk, peripheral neuropathy, muscle cramping, cold or discolored feet, and in severe cases, limb-threatening complications. Early identification of circulatory issues through vascular testing allows our team to intervene before these problems escalate — making vascular assessment a vital part of comprehensive podiatric care at In Motion Foot & Ankle.
Who Should Have Vascular Testing?
We recommend vascular testing for patients who present with certain symptoms or risk factors that suggest impaired lower extremity circulation. Common indications include:
Diabetes — Patients with diabetes are at significantly elevated risk for peripheral vascular disease. Routine vascular assessment is an important part of their ongoing foot care and helps guide decisions around wound care, footwear, and preventive management.
Non-healing wounds — If a wound is not progressing toward closure despite appropriate treatment, inadequate blood supply may be the underlying cause. Vascular testing helps determine whether circulatory compromise is a factor and whether additional intervention is needed.
Leg or foot cramping during activity — Pain or cramping in the legs while walking or exercising — a symptom known as claudication — can indicate significant arterial narrowing that warrants investigation.
Cold feet, skin color changes, or hair loss on the lower leg — These are classic signs of reduced arterial blood flow and should be evaluated promptly, particularly in patients with known cardiovascular risk factors.
Prior to foot or ankle surgery — Adequate circulation is necessary for proper post-surgical healing. Vascular testing may be performed as part of surgical planning to ensure the tissue environment can support recovery.
What Vascular Testing Involves
Vascular testing at In Motion Foot & Ankle is non-invasive and painless. We use specialized equipment to measure blood pressure at various points in the lower leg and foot, assess blood flow velocity, and evaluate the overall health of the arterial and venous systems. The most common test performed is the ankle-brachial index (ABI), which compares blood pressure in the ankle to blood pressure in the arm to screen for arterial disease. Additional tests may be ordered depending on clinical findings.
Results from vascular testing guide our treatment recommendations directly. Patients with adequate circulation may proceed confidently with planned treatments. Those with identified vascular compromise may be recommended for lifestyle modifications, medication adjustments, or referral to a vascular specialist when more advanced intervention is warranted. In all cases, the results are discussed with you in plain language so you understand what they mean for your foot health and overall care plan.

Frequently Asked Questions — Vascular Testing
What is vascular testing and why is it done?
Vascular testing evaluates blood flow through the arteries and veins of the lower extremities. It is performed to identify circulation problems that may be contributing to foot pain, slow-healing wounds, neuropathy symptoms, or increased risk of serious complications — particularly in patients with diabetes or known cardiovascular risk factors.
Is vascular testing painful?
No. Vascular testing at In Motion Foot & Ankle is completely non-invasive and painless. The tests involve using external equipment to assess blood pressure and blood flow at various points in the lower leg and foot — similar in comfort to having your blood pressure checked at a routine physical.
Who needs vascular testing?
Vascular testing is recommended for patients with diabetes, non-healing foot wounds, leg cramping during activity, cold or discolored feet, peripheral neuropathy, or known peripheral artery disease. It may also be part of pre-surgical evaluation to ensure adequate circulation for post-operative healing.
What is an ankle-brachial index (ABI)?
The ankle-brachial index is the most commonly used vascular screening test. It compares the blood pressure measured at the ankle to the blood pressure measured at the arm. A lower reading at the ankle relative to the arm can indicate narrowing of the arteries supplying the lower leg and foot, which is a hallmark of peripheral artery disease.
What happens after vascular testing?
After testing, our podiatric team reviews the results with you and uses them to guide your treatment plan. Patients with normal circulation can proceed with planned care. Those with identified circulatory issues may be recommended for lifestyle changes, medication review, closer wound monitoring, or referral to a vascular specialist for further workup or intervention.
Can poor circulation cause foot pain?
Yes. Insufficient blood flow to the feet can cause aching, cramping, burning, coldness, and even nerve symptoms similar to peripheral neuropathy. In patients with diabetes or PAD, circulation problems can also severely impair the ability of wounds to heal and increase infection risk. Vascular testing helps identify whether these circulatory factors are present.
Is vascular testing covered by insurance?
Vascular testing is often covered by insurance when medically indicated — for example, in patients with diabetes, non-healing wounds, or symptoms of peripheral artery disease. Coverage varies by plan and clinical context. Call our office at (281) 955-5500 to discuss your insurance coverage before your appointment.
