The shoulder abduction relief test, also called Bakody's test, is a medical maneuver used to evaluate for cervical radiculopathy. [1] Specifically, this test is used to evaluate for nerve root compression at C5-C7. It is often used when a patient presents with neck pain that radiates down the ipsilateral upper extremity. [2]
Spurling's test is somewhat specific when used for individuals with an abnormal electromyogram study and is a relatively sensitive physical examination maneuver in diagnosing cervical spondylosis or acute cervical radiculopathy. It is not a very sensitive test when used for individuals without classic radicular signs suggestive of cervical ...
The Apley scratch test specifically tests range of motion and in a normal exam, an individual should be able to reach C7 on external rotation, and T7 on internal rotation. Evaluation of distal pulses; Strength testing: wrist extension tests the radial nerve, finger abduction tests the ulnar nerve, and thumb apposition tests the median nerve.
The supraclavicular nerve is a cutaneous (sensory) nerve of the cervical plexus that arises from the third and fourth cervical (spinal) nerves. It emerges from beneath the posterior border of the sternocleidomastoid muscle, then split into multiple branches. Together, these innervate the skin over the shoulder.
The long thoracic nerve arises from the anterior rami of cervical spinal nerves C5, C6, and C7. [1] [2] [3] The root from C7 may occasionally be absent. [4] The roots from C5 and C6 pierce through the scalenus medius, while the C7 root passes in front of the muscle. [citation needed]
Due to the typical lead placement of deep brain stimulators from the "subclavicular area to the lateral posterior neck" and then to the "occipital area", there is a "theoretical risk of introducing electrical current through the leads" which could transmit "directly into the brain" and through the cervical nerve roots.
