What sensory disturbances may be present with lower motor neuron injury?

Sensory disturbances associated with lower motor neuron injury primarily include general sensory disturbances. Lower motor neurons are responsible for transmitting signals from the spinal cord to the muscles, which, when damaged, can lead to a variety of sensory and motor issues.

Individuals may experience a range of sensory abnormalities, including changes in sensitivity to stimuli, loss of reflexes, and muscle atrophy. Since lower motor neurons are involved in the peripheral nervous system, their injury can affect the way sensory information is relayed back to the central nervous system, resulting in varied sensory findings.

The other options, while they may pertain to sensory perception, do not typically arise directly from lower motor neuron lesions. Prosopagnosia is specifically related to higher cognitive functions involved in facial recognition, while loss of proprioception is more often linked to dorsal column injuries or upper motor neuron lesions. Hyperesthesia describes an increased sensitivity to stimuli and is more a feature of certain neuropathic conditions rather than a direct consequence of lower motor neuron damage alone. Thus, general sensory disturbances encompass the broader range of symptoms one might expect with lower motor neuron injuries.
