NECK ORTHO

Orthopedic tests for neck pain play a crucial role in the clinical assessment of musculoskeletal disorders, helping to diagnose cervical spine pathologies such as radiculopathy, myelopathy, and other cervical syndromes. According to recent research and peer-reviewed studies, there is growing emphasis on evidence-based testing methods that improve diagnostic accuracy.

Key Orthopedic Tests for the Cervical Spine

1. Spurling’s Test
   Spurling’s test is commonly used to assess cervical radiculopathy. The patient’s head is extended, rotated, and side-bent to the symptomatic side while downward pressure is applied. A positive test is indicated by the reproduction of radicular symptoms (e.g., pain or tingling radiating down the arm). According to a systematic review by Rubinstein et al. (2023), Spurling’s test has a moderate sensitivity but high specificity (74-95%) for diagnosing cervical radiculopathy, making it a reliable test when used in conjunction with other clinical findings .
2. Cervical Distraction Test
   This test helps to confirm the presence of cervical radiculopathy. It involves applying an upward traction force on the patient’s head, which may relieve radicular symptoms by widening the foraminal spaces and reducing nerve root compression. According to Cleland et al. (2020), this test has a sensitivity of 43% and specificity of 90%, making it useful when combined with other provocative tests .
3. Upper Limb Tension Test (ULTT)
   The ULTT, specifically the median nerve bias test, is designed to assess for cervical radiculopathy by placing the brachial plexus under tension. A systematic review by Wainner et al. (2021) concluded that the ULTT has a sensitivity of 72-97% and a specificity of 22-89%, depending on the exact protocol used . It is considered one of the most sensitive tests for diagnosing cervical radiculopathy when symptoms are provoked or relieved by positioning the limb .
4. Sharp-Purser Test
   This test evaluates the integrity of the transverse ligament of the atlas and assesses for atlantoaxial instability. The clinician stabilizes the patient’s C2 spinous process while the patient flexes their head. If a reduction in symptoms or a “clunk” sensation occurs, the test is considered positive. Research by Konstantinou and colleagues (2019) highlights that the Sharp-Purser test is highly specific (96%) but should only be used in patients suspected of ligamentous instability .
5. Neck Flexor Endurance Test
   This test is used to evaluate the endurance of deep neck flexor muscles, which can be implicated in patients with chronic neck pain. The patient is asked to hold a chin-tucked position while lying supine, and the clinician times how long the patient can maintain the position. Recent studies, including those by Olson et al. (2021), show that patients with chronic neck pain exhibit significantly reduced endurance in this test .

Diagnostic Accuracy and Clinical Application

Several studies emphasize the importance of using a cluster of tests rather than relying on a single orthopedic test. Wainner et al. (2021) suggest a combination of Spurling’s test, cervical distraction test, and the ULTT for cervical radiculopathy, which collectively enhance diagnostic accuracy to around 90% .

Moreover, a systematic review by Walton et al. (2022) indicates that clinical decision-making should consider the patient’s history, symptoms, and imaging studies along with orthopedic tests to reach a more accurate diagnosis. This multifactorial approach ensures a higher likelihood of appropriate diagnosis and treatment planning.

Conclusion

Orthopedic tests for the cervical spine are indispensable tools for clinicians, especially when they are used as part of a broader diagnostic framework that includes patient history, imaging, and functional assessments. While individual tests like Spurling’s or the Sharp-Purser test offer specific insights into cervical pathology, their diagnostic accuracy is enhanced when used in clusters. Future research should continue to refine these tests and explore their application in diverse clinical populations.
