Alternating lumbar lateral shift: a case report.

BACKGROUND: A lumbar lateral shift (LLS) is a common clinical observation in patients with low back pain (LBP), and a shift contralateral to the side of pain is the most common presentation. An LLS that can rapidly alternate sides presents several treatment difficulties and has rarely been described. The purpose of the current case report was to describe the presentation and management of a patient with an alternating LLS. CASE DESCRIPTION: A 39-year-old male with a 7-week history of LBP and previous lower extremity radicular pain was referred to physical therapy. An alternating LLS was present. OUTCOMES: The patient was treated for six visits over 37 days. Treatment included modified self-correction of the LLS, motor control and trunk muscle endurance training, and development of an activity management program. The patient's LLS resolved, his worst pain improved from 3/10 to 0/10, and the Oswestry Disability Index improved from 26% to 4% disability. The patient reported maintenance of improvement at 6-month follow-up. DISCUSSION: The current approach produced a positive outcome in a patient with an alternating LLS. The current understanding of mechanisms and optimal treatment of an alternating LLS is limited. LEVEL OF EVIDENCE: 4.
