Diplegia vs. Paraplegia — What's the Difference?

"Diplegia" is a term that is most often associated with cerebral palsy and describes paralysis that affects symmetrical parts of the body. In the context of cerebral palsy, it mainly refers to both legs being affected, but the arms can be involved to a lesser extent. This term does not specify which parts are paralyzed but emphasizes the symmetrical nature of the affliction. On the other side, "Paraplegia" is a form of paralysis where there's an impairment in motor or sensory function of the lower extremities, commonly resulting from spinal cord injuries or diseases.

When observing causes, "Diplegia" often stems from brain injuries, especially those sustained during birth or shortly after. Such injuries can lead to cerebral palsy, where diplegia is one specific form. In contrast, "Paraplegia" typically arises from injuries to the thoracic, lumbar, or sacral regions of the spinal cord. Events such as traumatic accidents, tumors, or infections can damage these areas and lead to paraplegia.

In terms of manifestation, "Diplegia" usually presents with muscle stiffness (spasticity) in the affected regions, potentially causing walking difficulties. "Paraplegia," meanwhile, results in a total or partial loss of sensation and movement in the legs and the trunk below the level of injury. This often necessitates the use of mobility aids such as wheelchairs.
