Neuro Anatomy and Neurodynamics Cervical Spine

Neuro Anatomy Important for neurological assessment Helps with tension testing and neurodynamic treatments Knowing anatomy will help identify potential courses of radicular pain or radiculopathy E.G paraesthesia in the hand- is this in a dermatome pattern or a peripheral nerve pattern

Spinal Nerves

Cervical Nerve Roots

Brachial Plexus

Axillary Nerve

Musculocutaneous Nerve

Ulnar Nerve

Radial Nerve

Median Nerve

Dermatomes and Myotomes Vs Peripheral Nerve Remember the cutaneous and motor distribution of a peripheral nerve IS NOT the same as dermatome and myotome patterns Nerve roots will progress into multiple peripheral nerves E.g C8 nerve root is present in ulnar, median and radial peripheral nerves

Neurodynamics Cervical Spine

The Neurodynamic System Interaction of 3 components – Mechanical Interface – Neural Structures – Innervated Tissues

Abnormal Neurodynamic System Can be the result of one or a combination of: – Dysfunctional Tension – Dysfunctional Sliding – Dysfunctional Compression

Tension

Sliding

Compression

Movement of the Neural System The nervous system will generally slide towards the moving joint distally and proximally to increase the available slack

Median Nerve Testing

Ulnar Nerve Testing

Radial Nerve Testing

Look for….. Pain ROM Paraesthesia or Numbness

Structural Differentiation Perform the test Make a change 2 joints away from the symptoms Does it increase or decrease symptoms? Does it make no change?

Dermatomes

Myotomes C1/2C3

Myotomes C4C5

Myotomes C6

Myotomes C7

Myotomes C8T1
