Central cord syndrome typically affects which areas and spares which?

Central cord syndrome is primarily characterized by its disproportionate impact on the upper extremities compared to the lower extremities. This condition occurs due to damage or injury to the central part of the spinal cord, often resulting from mechanisms like hyperextension injuries, especially in older adults with pre-existing cervical spinal stenosis.

The defining feature of central cord syndrome is that it typically affects the motor function of the arms more than that of the legs. Thus, individuals may experience weakness, loss of fine motor skills, or paralysis in the upper limbs, while the lower limbs are often less affected and may retain strength and control. This is why the correct response identifies that the syndrome affects the arms and spares the legs.

Recognizing this pattern is crucial for appropriate diagnosis and management, as interventions may focus on rehabilitation strategies that prioritize upper limb function while maintaining lower limb strength.
