Describe your assessment plan for this patient (sacroiliac dysfunction versus short leg syndrome).

1. A 35-year-old man complains of “back pain.” He complains that his back is stiff and sore when he gets up in the morning and that the stiffness remains for most of the day. Sclerosis of the sacroiliac is evident on x-ray. Describe your assessment plan for this patient (ankylosing spondylitis versus osteoarthritis of the sacroiliac joints).

2. An 18-year-old female figure skater complains of back pain that increases when she is skating; the pain is prominent on one leg. The ASIS and PSIS are higher on the right side. Describe your assessment plan for this patient (sacroiliac dysfunction versus short leg syndrome).
