A study of Date and Gray was undertaken to investigate the frequency of cervical radiculopathy and suprascapular neuropathy in patients with shoulder pain who were initially diagnosed with a musculoskeletal syndrome. Thirty-three subjects with a diagnosis of unilateral or bilateral impingement syndrome were entered into the study. A neurological examination was performed, followed by electromyography on 38 upper extremities and associated cervical paraspinal muscles to search for electrodiagnostic evidence for a suprascapular neuropathy and/or cervical radiculopathy. There were no subjects with electrodiagnostic evidence for suprascapular neuropathy. In two studies (5.3%), there was electrodiagnostic evidence for a C5/6 radiculopathy, and in nine (23.7%) additional subjects, there was electrodiagnostic evidence for a possible cervical radiculopathy. The remaining 27 (71.1%) studies showed no significant electrodiagnostic evidence for a cervical radiculopathy. Of the 11 subjects with abnormal electrodiagnostic studies, the neurological examination in 7 (63.6%) was normal except for pain-limited manual muscle testing, and the other 4 (36.4%) had an abnormality in either sensation testing, muscle bulk, or muscle stretch reflexes. One case of a patient with an initial diagnosis of soft tissue injury is presented. In patients undergoing evaluation for shoulder pain, cervical radiculopathy as a possible etiology should be considered, even when there is an equivocal clinical examination ¹⁾.
