Purpose
[edit | edit source]

 To assist in ruling in or out the diagnosis of cervical radiculopathy.

The Rule
[edit | edit source]

 The following criteria are considered predictive of the presence of cervical radiculopathy:  positive upper limb tension test A (ULTTa), involved-side cervical rotation range of motion less than 60 degrees, positive distraction test, and positive Spurling's test A.  Definitions of posititive provocative test results are as follows:

1. ULTTa: Any one of the following:  A) symptom reproduction; B) side-to-side difference >10 degrees in in elbow extension; or C) with regard to involved/painful side, ipsilateral neck lateral flexion decreases symptoms and/or contralateral neck lateral flexion increases symptoms.

2. Distraction test:  symptom reduction.

3. Spurling's A:  symptom reproduction.

 Clinical values of results are as follows:

    Number of Positive Criteria   Sensitivity (95% CI)   Specificity (95% CI)    Positive LR  Negative LR*
                   Two      0.39 (0.16-0.61)      0.56 (0.43-0.68)    0.88 (1.5-2.5)       1.09
                  Three      0.39 (0.16-0.61)      0.94 (0.88-1.0)    6.1 (2.0-18.6)       0.65
                  Four      0.24 (0.05-0.43)      0.99 (0.97-1.0)   30.3 (1.7-538.2)       0.77
