Diagnosis and Imaging
The journey toward Carpal Tunnel Surgery begins with a highly detailed diagnostic phase. Because hand numbness can also be caused by neck issues (cervical radiculopathy) or elbow compression, a physical exam alone is not enough to confirm the diagnosis. At Liv Hospital, we follow a structured protocol where specialists use provocative tests to recreate your symptoms. This baseline data is essential for measuring your progress after the surgery and for identifying the exact site of nerve entrapment.
The first line of diagnosis involves hands-on clinical maneuvers that increase the pressure on the median nerve.
If these maneuvers trigger tingling or numbness in the fingers, it is a strong clinical indicator that Carpal Tunnel Surgery may be necessary to relieve the entrapment.
Nerve Conduction Velocity studies are the “gold standard” for diagnosing the severity of the condition before Carpal Tunnel Surgery.
This test provides objective, numerical data that allows the team at Liv Hospital to determine if the nerve damage is mild, moderate, or severe, helping to prioritize the timing of the surgical intervention.
An EMG is often performed alongside nerve conduction studies to assess the health of the muscles in the hand.
If the EMG shows signs of muscle distress, Carpal Tunnel Surgery is usually recommended urgently to prevent permanent muscle wasting (atrophy), which would be difficult to reverse even after surgery.
Ultrasound has become an invaluable tool for visualizing the internal structure of the wrist before Carpal Tunnel Surgery.
Specialists at Liv Hospital use ultrasound to provide a visual “map” of the wrist, ensuring that the surgeon knows exactly what to expect before the first incision is made.
In complex clinical cases where the diagnosis remains unclear, an MRI may be recommended.
Using MRI technology ensures that the Carpal Tunnel Surgery is targeted specifically at the area of concern, preventing unnecessary exploration of the joint.
Because systemic inflammation can drive nerve compression, we often perform blood work as part of the diagnostic evaluation.
Addressing the underlying immunological or metabolic cause is just as important as the Carpal Tunnel Surgery itself for achieving a lasting recovery and preventing recurrence in the other hand.
Before the surgery, a detailed map of your hand’s current function is created.
This data serves as the clinical “baseline.” After your Carpal Tunnel Surgery, these tests are repeated to objectively track how quickly your nerve and muscle function are returning to normal.
A critical part of the evaluation is the differential diagnosis, which means ruling out other conditions that look like carpal tunnel syndrome.
By systematically ruling out these “lookalikes” through laboratory tests and high-tech imaging, our expert team at Liv Hospital ensures that the treatment provided is perfectly targeted to the actual site of compression.
At the conclusion of the evaluation phase, the surgical team meets to review all your test results. You will then meet with your surgeon for a final consultation. During this session, the visual findings from your ultrasound and the numerical data from your nerve studies are explained in detail. At Liv Hospital, we believe in a transparent and informed diagnostic process. If the evidence shows that the nerve is at risk, we will discuss the Carpal Tunnel Surgery in detail, ensuring you are ready for a future of hand comfort and strength.

The most common tests are physical maneuvers like the Durkan compression test, Phalen’s test, and Tinel’s sign. To confirm the diagnosis and check severity, doctors use Semmes-Weinstein monofilament testing and electrodiagnostic studies like EMG and nerve conduction studies.
You do not need to fast or be put to sleep. The test is done on an unanesthetized patient. You should avoid putting lotions or oils on your skin on the day of the test to ensure the electrodes stick properly. Wear loose clothing to allow access to your arm.
The test involves the doctor pressing their thumbs over your carpal tunnel for 60 seconds. It is not designed to be painful, but if you have carpal tunnel syndrome, it will reproduce your symptoms, causing numbness, tingling, or discomfort in your fingers.
The Semmes-Weinstein monofilament test is very sensitive for diagnosing early carpal tunnel syndrome because it detects changes in large sensory fibers. Electrodiagnostic tests (EMG/NCV) are highly accurate for confirming the diagnosis and ruling out other conditions.
You need advanced testing like EMG/NCV if your diagnosis is unclear, if you are considering surgery, or if you have signs of severe nerve damage like muscle weakness or loss of fine motor control. It helps distinguish CTS from neck issues or other nerve entrapments.
