Upper Limb Tension Test I is a median nerve-biased neurodynamic test. It assesses symptom response to a sequence of shoulder, elbow, wrist, hand and cervical movements. A 2021 diagnostic accuracy study found that single ULNTs did not significantly change post-test probability for cervical radiculopathy, but combinations of ULNTs had better rule-in and rule-out value.
A client reports neck-related arm symptoms, tingling into the hand or symptoms that change with arm position. They may feel worse with overhead activity, desk posture or sustained reaching. Upper Limb Tension Test I can help assess whether median nerve-biased neurodynamic loading reproduces familiar symptoms.
The test should not be interpreted as “nerve damage” because it is positive. It assesses symptom response to mechanical loading of neural and surrounding tissues and should be interpreted with history, neurological screen and related tests.
Test name: Upper Limb Tension Test I
Also known as: ULNT1, ULTT1, Median Nerve Bias Test
Body region: Cervical spine, brachial plexus, median nerve pathway and upper limb
Purpose: Assess median nerve-biased neurodynamic symptom response
Positive finding: Familiar symptoms reproduced and meaningfully changed by structural differentiation
Negative finding: No familiar symptoms or no meaningful neurodynamic symptom change
Best used with: Cervical ROM, neurological screen, Spurling’s, cervical distraction, Phalen’s, wrist Tinel’s and symptom history
Key limitation: Single ULNTs have limited diagnostic value for cervical radiculopathy when used alone
Upper Limb Tension Test I is a neurodynamic test that biases the median nerve pathway. The upper limb is moved through a sequence that commonly includes shoulder depression, shoulder abduction, wrist and finger extension, forearm supination, shoulder external rotation and elbow extension, with cervical side flexion used for structural differentiation.
The exact order may vary, so the sequence used should be recorded.
ULTT1 is used when median nerve mechanosensitivity, cervical radicular symptoms or upper-limb neural symptom behaviour is being considered.
It may be useful for clients with neck-related arm pain, hand paraesthesia, carpal tunnel-type symptoms, forearm symptoms, desk posture symptoms, overhead symptoms or symptoms that change with cervical position.
The test assesses symptom response to median nerve-biased neurodynamic loading. It does not diagnose cervical radiculopathy, carpal tunnel syndrome or nerve entrapment on its own.
Symptoms may be influenced by nerve sensitivity, muscle flexibility, joint stiffness, pain sensitivity, guarding, cervical contribution, thoracic outlet symptoms or peripheral entrapment.
This test may be useful for clients with neck and arm symptoms, median nerve distribution paraesthesia, suspected cervical radicular symptoms, carpal tunnel-type symptoms or upper-limb symptoms influenced by posture and arm position.
Use when neurodynamic symptom behaviour is relevant and the client can tolerate gradual arm positioning.
Use caution with severe or progressive neurological signs, acute nerve injury, severe irritability, recent surgery, acute trauma, vascular symptoms, dizziness or symptoms that remain aggravated after testing.

Optional neurological screen notes
Position the client supine near the edge of the table.
The shoulder is relaxed. The tested arm is accessible.
Stand beside the tested arm and control each movement gradually.
Support the shoulder, wrist and hand as needed while guiding the test sequence.
Maintain shoulder depression if included and prevent trunk rotation or shoulder elevation compensation.
Gradually move through the selected sequence: shoulder depression, shoulder abduction, wrist and finger extension, forearm supination, shoulder external rotation and elbow extension. Use cervical side flexion toward or away from the tested side to assess symptom change.
Ask the client to report pain, stretch, tingling, numbness, burning, symptom location and whether symptoms are familiar.
A positive finding is reproduction of familiar symptoms that are meaningfully altered by structural differentiation, such as cervical side flexion or releasing distal components.
A negative finding is no familiar symptoms or no meaningful change with structural differentiation.
Stop if symptoms increase sharply, paraesthesia persists, neurological symptoms worsen, dizziness occurs or the client cannot tolerate the test.
Do not force end range. Record the symptom onset point and which component changed symptoms.
A positive ULTT1 may suggest median nerve-biased mechanosensitivity or neurodynamic contribution when familiar symptoms are reproduced and altered by structural differentiation. It does not identify the exact site of involvement.
A negative test reduces suspicion of median nerve-biased neurodynamic involvement under the tested conditions, but it does not exclude cervical radiculopathy, carpal tunnel syndrome or peripheral nerve symptoms.
Interpretation is stronger when combined with neurological screen, cervical tests, wrist tests, symptom distribution and functional history.
A 2021 prospective diagnostic accuracy study assessed ULNT1, ULNT2a, ULNT2b and ULNT3 in 85 people with suspected cervical radiculopathy. Single ULNTs generally did not significantly alter post-test probability when used alone. ULNT3 had the strongest positive post-test probability change among single tests at 73.28%. Three of four positive ULNTs had LR+ 12.89, while having no positive ULNTs had LR- 0.08.
Condition or presentation: cervical radiculopathy
Population: 85 people with suspected cervical radiculopathy
Test variation: ULNT1, 2a, 2b and 3 using clinically similar criteria
Reference standard: clinical diagnosis and MRI verification by a neurosurgeon
Sensitivity: not provided for ULTT1 alone in the accessible summary
Specificity: not provided for ULTT1 alone in the accessible summary
Positive likelihood ratio: strongest when 3 of 4 ULNTs were positive, LR+ 12.89
Negative likelihood ratio: all ULNTs negative, LR- 0.08
Key limitations: single ULNTs had limited stand-alone value; combined interpretation performed better
A 2025 systematic review on upper-limb entrapment neuropathies also reported that diagnostic accuracy remains uncertain across different conditions and criteria.
A 2022 reliability study reported moderate to excellent reliability for upper limb neurodynamic tests when measuring the range between onset of stretching pain and submaximal pain. Median nerve testing showed higher relative reliability than radial and ulnar nerve testing.
Reliability improves when the same sequence, endpoint, symptom criteria and measurement method are used.
Common errors include moving too quickly, forcing symptoms, not using structural differentiation, treating stretch as positive, not recording symptom distribution and using the test as a stand-alone diagnosis.
Limitations include symptom overlap, variable sequences, nerve and non-nerve tissue loading, pain sensitivity and limited single-test diagnostic certainty.
Use ULTT1 to document median nerve-biased symptom behaviour, identify symptom onset positions, guide load modification and track changes across sessions.
Record test name, side tested, result as positive, negative, unclear or unable to test, sequence used, symptom onset component, pain score, symptom distribution, structural differentiation response, cervical position, elbow angle if measured, wrist position, comparison side, irritability, confidence in result and reason for stopping.
Add related cervical ROM, neurological screen, grip strength, Phalen’s, wrist Tinel’s, pronator teres testing and functional symptom notes.

It assesses median nerve-biased neurodynamic symptom response.
A positive result is familiar symptom reproduction that changes with structural differentiation.
No. Single ULNTs have limited diagnostic value for cervical radiculopathy when used alone.
Not by itself. Familiar symptoms and structural differentiation are more meaningful.
Record the sequence, symptom onset point, symptom distribution, structural differentiation response and comparison side.
ULTT1 is a median nerve-biased neurodynamic test.
Familiar symptoms plus structural differentiation are key.
Single ULNTs have limited diagnostic value for cervical radiculopathy alone.
Combined ULNT findings may be more clinically useful.
Measurz should capture sequence, symptoms and differentiation response.
