Many causes contribute to hyperventilation; however, the pathophysiology involved is still unknown, and the skeletal origins of the condition have scarcely been examined. We present a case of a 20-year-old man with a history of hyperventilation and subtle lower back pain due to spondylolysis of the fifth lumbar vertebra with grade I spondylolisthesis. The duration and frequency of hyperventilation increased after performing physical modality and abated after discontinuing physical modality. We discuss the relationship and associated pathophysiology between hyperventilation and spondylolysis, which is the first report in the literature. We suggest that physical therapy might be harmful for some patients with hyperventilation, because the hyperventilation might be a clinical manifestation of dysplastic lumbar spondylolysis.
