Can brachial plexus injury cause dizziness?

INTRODUCTION: In older adults, falls are the leading cause of injury requiring admission to the emergency department or hospital and can sometimes be fatal. 1,2 Brachial plexus injury and dizziness associated with Benign Paroxysmal Positional Vertigo (BPPV) are common results of trauma related falls.

Is brachial plexus part of the central nervous system?

The brachial plexus is a complex network of nerves which extends from the neck to the axilla and which supplies motor, sensory, and sympathetic fibers to the upper extremity. Generally it is formed by the union of the ventral primary rami of the spinal nerves, C5-C8 and T1, the so-called “roots” of the brachial plexus.

How do I strengthen my brachial plexus?

How is brachial plexus injury diagnosed?

To help diagnose the extent and severity of a brachial plexus injury, you may have one or more of the following tests:

  1. X-ray.
  2. Electromyography (EMG).
  3. Nerve conduction studies.
  4. Magnetic resonance imaging (MRI).
  5. Computerized tomography (CT) myelography.

Is brachial plexus injury a disability?

Brachial plexus damage can range from mild to severe disability in one arm. The disability may be temporary or permanent. When the disability is permanent, treatment may help lessen the severity of the disability.
