Objectives: Neck roots lesions are among the etiologies of cervical and arm pain. A detailed patient evaluation could assist the diagnosis, reduce imaging requests, and promote the treatment of cervical pain. We tried to estimate the value of pronator teres reflex in C6 and C7 roots irritation.
Methods: The present study comprises 118 participants, including 56 patients with C6 and C7 lesions and 62 normal controls. The reliability and usefulness of this reflex in C6 and C7 roots lesions were compared to positive electromyography and imaging with magnetic resonance.
Results: The sensitivity, specificity, positive predictive value, and negative predictive value for pronator teres reflex were 36.4%, 13.6%, 64.8%, and 4.6%, respectively.
Discussion: This reflex can be considered an additional reflex during the physical examination for C6 and C7 nerve roots injury, but its diagnostic value for C6 and C7 radiculopathy is unreliable to be used for screening purposes.
