Typical symptoms associated with a lumbosacral spine sprain or strain include pain and spasm localized over the posterior lumbar spinal muscle bellies lateral to the spinous process or at the insertion of the muscle at the iliac crest. With the patient in a standing position, evaluate for obvious deformities, changes in alignment, or difficulties in achieving changes in position or full range of motion. Evaluation of these signs may provide clues to muscle spasms and activities that worsen the patient's pain.
Evaluation of the lower extremities should include a motor examination, a sensory evaluation, and reflex testing at the knees and ankles. The straight leg raise test (Lasègue test) helps to evaluate disc involvement, sciatica, or a neurologic deficit. This test has high sensitivity and low specificity and is an important diagnostic tool in the workup of patients with low back pain. A positive flexion, abduction, and external rotation (FABER) test suggests sacroiliac joint inflammation; however, this test should be negative in lumbosacral sprains and strains.
