BACKGROUND AND OBJECTIVE

Cervical radiculopathy is typically identified due to the presence of arm pain, paraesthesia, or weakness with apparent dermatomal and myotomal symptoms for C2-3 and C5-8. While there are some clinical tests to identify cervical radiculopathy, there are currently no tests to identify cervical radiculopathy at C4.

This study aimed to assess the clinical utility of using the resisted levator scapulae (RLS) test in identifying patients with C4 radiculopathy on physical examination.

Cervical radiculopathy is typically identified due to the presence of arm pain, paraesthesia, or weakness with apparent dermatomal and myotomal symptoms for C2-3 and C5-8.
bulb
The resisted levator scapulae test offers clinicians a tool to screen for the presence of C4 radiculopathy without potentially provoking pain by performing a provocative test.

METHODS

  • A convenience sample of patients presenting with cervical pain with a suspicion of C4 radiculopathy was recruited from a private spine clinic.
