1. A 23-year-old man comes to you complaining of a low backache. He works as a dishwasher, and although the pain has been present for 5 months, he has not missed any work. The pain gets worse as the day progresses and is relieved by rest. X-rays reveal some sclerosis in the area of the sacroiliac joints. Describe your assessment plan for this patient (ankylosing spondylitis versus lumbar sprain).

2. A 13-year-old female gymnast comes to you complaining of low back pain. The pain increases when she extends the spine. Like most gymnasts, she is hypermobile in most of her joints. Describe your assessment plan for this patient (spondylolisthesis versus lumbar sprain).
