Low Back Pain in a Pregnant Patient: When to Use OMT
A 32-year-old woman at 28 weeks gestation presents with a 3-week history of low back pain that radiates to the left buttock. She describes the pain as aching and occasionally sharp, worsened by prolonged standing and relieved by lying down. She has no history of trauma, fever, or bowel/bladder dysfunction. On physical exam, she has a noticeable lumbar lordosis and a positive standing flexion test on the left. She has tenderness and hypertonicity in the left quadratus lumborum and gluteal muscles. Straight leg raise is negative bilaterally. She is hesitant to take any medications and asks about osteopathic manipulative treatment (OMT).
1. What OMT techniques would you consider for this patient, and what precautions would you take?
Read the worked answer
For a pregnant patient with low back pain and somatic dysfunction, gentle OMT techniques are appropriate. Consider muscle energy technique for the lumbar spine and pelvis, soft tissue technique for the quadratus lumborum and gluteal muscles, and positional release (strain-counterstrain) for tender points. Avoid high-velocity low-amplitude (HVLA) thrust techniques in the lumbosacral region due to ligamentous laxity from relaxin and the risk of placental abruption or discomfort. Also avoid prone positioning; use side-lying or modified positions with pillows for support. Precautions include monitoring for any signs of preterm labor, placental abruption, or worsening pain, and ensuring the patient is comfortable throughout. Obtain consent and explain the techniques. OMT can help reduce pain and improve function without medications.
2. What would be your next step if the patient developed a severe headache and visual changes after the OMT session?
Read the worked answer
Severe headache and visual changes in a pregnant patient at 28 weeks should raise immediate concern for preeclampsia. The next step is to check blood pressure and urine protein. If elevated blood pressure (≥140/90) and/or proteinuria are present, she should be sent to labor and delivery for further evaluation and monitoring. OMT is generally safe, but these symptoms are unrelated to the treatment and require urgent assessment. Preeclampsia can progress rapidly, so timely intervention is critical.
