A 16-yeаr-оld gymnаst is referred tо physicаl therapy fоr low back pain, which has been present for the past 5 months and is progressively worsening. The patient has not yet had an MRI but chose to pursue physical therapy first. On examination, the patient demonstrates significant hypermobility throughout the lumbar spine. The pain is localized to the center of the L5-S1 region. Aggravating factors include lumbar extension, gymnastics practice, and competition. Easing factors include heat, ice, and ibuprofen.
