How is cervical nerve root compression tested?

The most common diagnostic methods used to assess the presence of possible compression are radiographs, MRI and electrophysiologic studies (EMG + Nerve Conduction Studies) to examine the nerve root and nerve conduction velocity.

How do you test for c5 nerve roots?

The C5 nerve root is best examined by testing the strength of the deltoid muscle. Ask the patient to abduct the shoulders to 90 degrees. Place your hands over the elbows and ask the patient to maintain shoulder abduction as you press downwards. Compare the strength of shoulder abduction on each side.

What is a positive Spurling’s test?

A positive Spurling test indicates you have nerve root compression. This pain can affect your neck, shoulder, or arms. It sometimes feels similar to muscle weakness.‌ If you think you have a pinched nerve, or cervical radiculopathy, a positive Spurling test can help your doctor with a diagnosis.

What is the cervical quadrant test?

Purpose. The Spurling’s test (also known as Maximal Cervical Compression Test and Foraminal Compression Test) is used during a musculoskeletal assessment of the cervical spine when looking for cervical nerve root compression causing Cervical Radiculopathy.

What does C4 C5-C6 control?

C4 (along with C3 and C5) also helps power the diaphragm—the sheet of muscle that stretches to the bottom of the rib cage for breathing. C6 helps control the wrist extensors (muscles that control wrist extension) and also provides some innervation to the biceps.

How do you do a Spurlings test?

The examiner turns the patient’s head to the affected side while extending and applying downward pressure to the top of the patient’s head. A positive Spurling’s sign is when the pain arising in the neck radiates in the direction of the corresponding dermatome ipsilaterally. It is a type of cervical compression test.

What are the roots of the cervical plexus?

These nerve roots emerge from the spinal column through lateral intervertebral foramina. The first four cervical nerves collectively form the cervical plexus. The second four nerves, together with the first thoracic nerve, form the brachial plexus ( Fig. 4-1 ).

How do you decompress cervical nerve roots?

Decompression of compromised cervical nerve roots or spinal cord can be approached either posterior between the laminae (similar to the lumbar spine approach) or anterior on either side of the trachea and esophagus through the intervertebral disc space.

What are cervical nerves and how do they work?

Cervical nerves are spinal nerves that arise from the cervical region of the spinal cord. These nerves conduct motor and sensory information via efferent and afferent fibers, respectively, to and from the central nervous system. While classified as peripheral nerves, the motor cell body resides in the anterior horn of the spinal cord.

How many nerve roots are in the cervical spine?

The cervical spine consists of eight pairs of spinal nerves. Each spinal nerve consists of a dorsal root (sensory component) and a ventral root (motor component). These nerve roots emerge from the spinal column through lateral intervertebral foramina.
