Background: Abdominal aortic aneurysms (AAAs) are found in 1-12% of older males. Low back pain (LBP) is prevalent with incidence increasing with age and can respond to manual therapy (MT). To date, the safety of the application of MT for LBP in the presence of a known AAA has not been reported. This case reports on the short-term effects of MT in a patient with LBP and AAA and pre- and post-therapy imaging.
Case description: A 76-year-old male presented with mechanical LBP, groin pain, and a known 4.2-cm AAA. A lumbar magnetic resonance imaging showed significant multilevel abnormalities. Abdominal screening did not elicit back or groin pain. Lumbar and hip range of motion and accessory motion testing reproduced his complaints. He was treated with lumbar and hip MT.
Outcomes: After three visits, he reported that his groin pain resolved, and his back pain could be managed with home exercise. He reported a +6 on the global rating of change. Repeated follow-up imaging of his AAA demonstrated no significant change of his AAA.
Discussion: No immediate adverse events were recorded, and repeated follow-up imaging indicated no significant AAA expansion. Considering that mobilization causes similar displacement to active motion, research into the safety of MT in this population is warranted as are guidelines for appropriate initial and ongoing clinical screening during treatment in this population.
