Final answer:
Sensory tests address various submodalities of somatic senses and can point to trauma in the spinal cord or cerebral cortex. Disorders of sensory awareness related to practice areas include impairments in praxis, gnosis, and language components associated with aphasias.
Step-by-step explanation:
Sensory tests address the various submodalities of the somatic senses: touch, temperature, vibration, pain, and proprioception. Results of the subtests can point to trauma in the spinal cord gray matter, white matter, or even in connections to the cerebral cortex.
Disorders of sensory awareness related to the areas of practice can include impairments in praxis and gnosis, which are related to the conscious perception and cortical processing of sensory information. Damage to specific cortical areas can result in deficits in the ability to transform verbal commands into motor responses or recognize and manipulate common objects.
Additionally, language components are integral to praxis and gnosis, and certain types of aphasias can result in deficits in using verbs or nouns. Damage to specific regions in the frontal and temporal lobes can be associated with these language impairments.
