What condition is characterized by paralysis with no medical basis after a traumatic event?

The condition characterized by paralysis with no medical basis following a traumatic event is known as conversion disorder. This disorder involves neurological symptoms, such as paralysis or loss of sensation, that cannot be explained by medical conditions. The symptoms are typically triggered by psychological factors, such as trauma or stress, reflecting a psychological conflict manifesting as a physical symptom.

In conversion disorder, individuals are not intentionally producing their symptoms; rather, the symptoms are a genuine response to emotional distress. This distinguishes it from physical disorders where there is an identifiable organic cause. In this case, an individual may experience paralysis after a traumatic experience without any underlying neurological or physical issues.

The other options involve different psychological or medical characteristics where the physical symptoms typically arise from other causes, such as misinterpretations of bodily sensations or ongoing anxiety, but they do not specifically describe the phenomenon of paralysis due to psychological conflict, making conversion disorder the correct choice.
