Neurodynamic testing assesses the mobility and sensitivity of the nervous system, including peripheral nerves, nerve roots, and surrounding tissues. During testing, the practitioner applies gentle, specific movements to place controlled mechanical stress through a nerve pathway.
A healthy nerve adapts to movement without provoking symptoms. A sensitised or restricted nerve may reproduce familiar sensations such as sharp pain, tingling, burning, numbness, or pulling. These responses help determine whether symptoms are neural in origin rather than purely muscular or joint-related.
Why Neurodynamic Testing Is Important
Many people spend months treating the wrong structure. Muscles are repeatedly worked on, joints are mobilised, yet symptoms return or never fully resolve. If a nerve is irritated, compressed, or restricted, treating muscles alone may only provide temporary relief.
Neurodynamic testing helps to:
This leads to more accurate diagnosis and improved long-term outcomes.
Pain, tingling, numbness, weakness, or unexplained loss of movement are not always caused by tight muscles or stiff joints. In many cases, the nervous system itself is involved. Neurodynamic and neurological testing are essential assessment tools used in physiotherapy and myotherapy to evaluate how well nerves move, tolerate load, and communicate with the brain.
When nerves cannot glide freely, become sensitised, or fail to transmit clear signals, symptoms may persist despite repeated muscle or joint treatment. A comprehensive neural assessment helps identify these hidden contributors and guides more precise, effective care.
Neurodynamic testing is commonly used to assess and manage:
If symptoms travel, change with posture, or feel sharp, electric, burning, or like pins and needles, a neural assessment is essential.
How Neurodynamic Tests Work
Neurodynamic tests are based on three core principles:
The practitioner observes how symptoms respond when nerve pathways are gently loaded. Pain, tingling, or restricted movement suggests neural sensitivity or mechanical interference.
Specific joint positions are used to target individual nerves. In the upper limb, shoulder, elbow, wrist, and finger positioning assesses the median, ulnar, or radial nerves. In the lower limb, hip, knee, and ankle positioning assesses the sciatic nerve and lumbar nerve roots.
Additional movements such as neck side bending or ankle dorsiflexion are added to increase test sensitivity. Predictable changes in symptoms strengthen the evidence of neural involvement.
A test is considered positive when it reproduces the patient’s familiar symptoms and those symptoms change with sensitising or relieving movements.
Common Neurodynamic Tests
Upper Limb Tension Tests (ULTTs) assess nerves of the brachial plexus, including the median, radial, and ulnar nerves. These are commonly used for neck pain, arm pain, carpal tunnel symptoms, and postural nerve irritation.
Lower limb tests include the Straight Leg Raise, which assesses sciatic nerve and lumbar nerve root irritation, and the Slump Test, which assesses the lumbosacral nerve roots and sciatic nerve in positions that commonly aggravate symptoms.
Neurological Testing: Communication Between Body and Brain
Neurodynamic testing is most effective when combined with a full neurological assessment. This includes dermatome testing, myotome strength testing, and deep tendon reflex assessment. Together, these tests evaluate how information travels from the body to the brain and how motor commands travel from the brain back to the body.
Pain is not simply a tissue problem. It is a neurological output created by the brain based on the quality of information it receives. Neurological testing helps determine whether that information is clear, delayed, distorted, or blocked.
Dermatome Testing: Sensory Input to the Brain
Dermatomes are areas of skin supplied by specific spinal nerve roots. Sensory fibres transmit information such as touch, pressure, temperature, and pain back to the spinal cord and brain.
Different fibre types carry different information:
When a nerve root is irritated or compressed, these fibres may misfire, causing numbness, pins and needles, burning sensations, or hypersensitivity. Dermatome testing helps identify whether sensory signals are accurately relayed and localises the spinal level involved.
Myotome Testing: Motor Output From the Brain
Myotomes are groups of muscles controlled by a single spinal nerve root. Myotome testing assesses the motor pathway that carries signals from the brain, down the spinal cord, and out to the muscles.
If this pathway is compromised, it may result in:
This weakness is neurological rather than purely muscular. Strengthening alone will not restore function until neural signalling improves. Myotome testing helps distinguish true neurological weakness from pain inhibition or general deconditioning.
Deep Tendon Reflex Testing
Deep tendon reflexes assess communication between sensory input, the spinal cord, and motor output. Commonly tested reflexes include the patellar and Achilles reflexes in the lower limb, and the biceps, triceps, and brachioradialis reflexes in the upper limb.
Altered reflex responses can indicate nerve root involvement or central nervous system irritation, providing further confirmation of neural dysfunction.
Why Combining These Tests Matters
Individually, each test provides valuable information. Together, they create a clear neurological picture. A comprehensive assessment may reveal:
When these findings align, clinicians can confidently identify neural involvement and determine whether the issue is peripheral, spinal, or both.
How This Guides Treatment
When neural involvement is identified, treatment strategies change. Instead of aggressive stretching or repeated deep tissue work, care focuses on:
This approach is essential for conditions such as radiculopathy, sciatica, post-surgical nerve sensitivity, and chronic pain where the nervous system has become sensitised.
Neurodynamic and neurological testing assess how the nervous system moves, senses, and communicates with the brain. This comprehensive approach goes beyond symptom management to identify the true source of dysfunction.
When pain, weakness, tingling, or numbness are present, a detailed neural assessment is critical for achieving effective, lasting results.
