In terms of central cord syndrome, which function is often impacted?

Central cord syndrome primarily affects the upper extremities more than the lower extremities due to the anatomical organization of the spinal cord. In this condition, the injury usually involves damage to the central part of the spinal cord, leading to a characteristic pattern of weakness, particularly in the hands and arms, while the legs may retain relatively better function.

Bladder function can also be affected due to its neural innervation, which involves a complex interplay of both voluntary and involuntary controls. In individuals with central cord syndrome, bladder symptoms may manifest as a result of disruption to the neural pathways that regulate bladder control. This can include symptoms like urgency, frequency, or incontinence, which are significant aspects of the syndrome.

The other functions listed, such as leg function, vibration sense, and proprioception, are less prominently affected in central cord syndrome, as the injury typically affects the central spinal tracts while leaving peripheral pathways relatively intact. This is why bladder function is considered notably impacted in the context of central cord syndrome.
