Which statement regarding paralysis is correct?

The correct statement is that a paralyzed patient has lost the ability to voluntarily move a body part. This definition aligns with the medical understanding of paralysis, which refers to a loss of muscle function in a part of the body, often caused by injury, disease, or neurological conditions that affect the nervous system. In paralysis, the affected muscles cannot be controlled voluntarily, meaning that the individual cannot initiate movement in the paralyzed area.

Other related statements present varying degrees of misunderstanding about paralysis. Paralysis does not always mean an absence of sensory function; depending on the type and extent of the injury, some patients may retain sensory capabilities even when their motor functions are compromised. Additionally, injuries at different levels of the spine—such as the cervical spine—can lead to quadriplegia, while injuries at the thoracic or lumbar spine typically result in paraplegia. Lastly, it is not accurate to say that most paralyzed patients have normal sensation or hyperesthesia, as many individuals experience varying levels of sensory loss; thus, this statement misrepresents the experiences of most patients with paralysis.
