2021-01-26 12:00 AM

Determination of sensory level has local significance at the location of spinal cord lesions. Spinal cord injuries cause sensory defects to occur at a level, and below the level of damage.

Description

The sensory level is the marrow cavity in which a sudden loss of sensation occurs.

Reason

Common

Spinal cord injury.

Mass damage (eg. Tumor, abscess, cerebral vascular malformation - AVM).

Multiple sclerosis.

Less common

Transverse myelitis.

Anterior myelogenous syndrome.

Epidural abscess

Figure. Cross skin feeling

Mechanism

Spinal cord injuries cause sensory defects to occur at a level, and below the level of damage. The sensory pathway above the lesion is unaffectedly leading to, the sensation is maintained intact in the spinal cord layers above the lesion.

Meaning

Determination of sensory level has local significance at the location of spinal cord lesions.
