What physical examination test is likely to provoke pain in a patient with ulnar nerve symptoms?

• A. Cervical Compression Test
• B. Posteroanterior glide at C7
• C. Shoulder Abduction Test
• D. Prone Cervical Extension Test

Answer: (B)

The posteroanterior glide at C7 is likely to provoke pain in a patient with ulnar nerve symptoms due to the anatomical relationship between the cervical spine and the nerve pathways. The ulnar nerve is primarily affected by issues arising in the cervical spine, especially at the lower levels such as C8 and T1.

When performing a posteroanterior glide at C7, pressure is applied to the spinous processes or articular facets in a posterior direction. This movement can potentially exacerbate discomfort or exacerbate symptoms associated with ulnar nerve dysfunction, particularly if there is cervical radiculopathy or when there is irritation along the nerve pathway. The ulnar nerve's proximity to the lower cervical levels means that any mechanical stress or impingement at this area can lead to enhanced sensory symptoms, such as paresthesia or pain radiating into the ulnar distribution.

In contrast, while cervical compression tests can also provoke symptoms, they tend to do so in a more generalized manner and are not as directly linked to ulnar nerve symptoms as the posteroanterior glide. The shoulder abduction test is used to relieve tension on the ulnar nerve rather than provoke it. Likewise, the prone cervical extension test
