Quantitative sensory testing (QST) is a set of painless tests that measure how well your nerves sense different sensations like touch, temperature, vibration, and pain. It helps doctors find out if you have nerve damage and how severe it is.
Key facts
Quantitative sensory testing is a specialized test, not a routine check-up. It is most often used when a person has symptoms of nerve damage that are not clear from a standard physical exam.
QST is used for people of any age who have symptoms such as numbness, tingling, burning pain, or loss of sensation. It is often used in people with diabetes, chronic pain conditions, or after a stroke.
Quantitative sensory testing is done by a neurologist or a trained specialist. It involves using devices to apply specific stimuli (like vibration, cool temperature, or gentle pressure) to different body parts. You simply respond when you feel the sensation. The results are compared to normal values for your age.
The test is painless, though you may feel mild discomfort from heat/cold or light pricks. It usually takes about 30–60 minutes. You will be asked to relax and report when you feel sensations. There are no needles or injections. Your doctor will explain the results after the test.
Quantitative sensory testing itself does not treat nerve problems. Instead, it helps your doctor decide which treatment is best suited for the type of nerve damage you have. Treatment may include medications, physical therapy, lifestyle changes, or managing underlying conditions like diabetes.
Treatment depends on the cause of nerve damage. Doctors may prescribe medications to reduce nerve pain (such as certain antidepressants or anticonvulsants), recommend physical or occupational therapy to improve strength and coordination, or suggest vitamin supplements if deficiencies are found. Always follow your doctor's advice and do not take any medication without their guidance.
Living with nerve symptoms can be challenging, but many people manage well with the right support. Keep a symptom diary to help your doctor track changes. Use safety measures at home, like grab bars in the bathroom and good lighting to prevent falls.
Eat a balanced diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats. If you have diabetes, work with a dietitian to keep blood sugar stable. Exercise improves blood flow and can reduce nerve pain – start slowly and increase gradually.
Not all nerve damage can be prevented, but you can lower your risk. Keep chronic conditions like diabetes and high blood pressure under control. Eat a healthy diet, exercise regularly, and avoid excessive alcohol. Protect your nerves from injury by using proper ergonomics at work and during sports.
Vaccines do not prevent most causes of nerve damage, but staying up to date with vaccines (like shingles vaccine) can help prevent some viral infections that may cause nerve problems.
If you have diabetes, research suggests you should have an annual foot exam to check sensation. Talk to your doctor about whether regular QST or other nerve tests are right for you.
With early diagnosis and proper management, many people with nerve damage can stabilize their symptoms and maintain good quality of life. QST helps guide treatment, which can slow progression and relieve pain. Your healthcare team is there to support you every step of the way.

If symptoms are severe, worsening, or urgent, call your local emergency number or seek emergency care.
When a nerve is compressed (like in carpal tunnel syndrome or a herniated disc), surgery to relieve pressure may be considered if other treatments do not help.
Chronic pain or numbness can be frustrating and may lead to anxiety or depression. It is okay to feel this way. Talk to your doctor about your feelings – they can refer you to a counsellor or support group. You are not alone.
