Chronic Low Back Pain With High Fear and a Worker's Compensation Claim
A 44-year-old warehouse worker has had low back pain for 14 months after a lifting injury. Imaging shows a mild disc bulge without nerve root compression. He has not worked since the injury and reports pain of 7/10 at rest. He avoids bending, sits carefully, and says "my back is damaged and I'll make it worse." He scores high on a fear-avoidance measure and reports poor sleep and low mood. His employer offers a modified-duty program, but he is reluctant. He asks you to "fix the disc" and says he wants an MRI of his whole spine. He is 6 weeks into your care with little change in function.
1. What psychosocial factors are most relevant, and how do they shape your intervention?
Read the worked answer
Key factors are fear-avoidance beliefs, catastrophizing ("my back is damaged"), low mood and poor sleep, and prolonged work absence, all of which predict persistent disability more strongly than imaging findings.
Implications:
- Education should target the belief that the back is fragile, using a clear explanation that a mild disc bulge is common and not the cause of ongoing pain.
- Graded exposure to feared movements (bending, lifting) is central, rather than reassurance alone.
- Address sleep and mood as part of the plan, with referral to behavioral health if needed.
- The modified-duty offer is a therapeutic opportunity, not a threat; work is a functional goal and a predictor of better outcomes.
A purely biomechanical strengthening program will likely fail if these factors are not addressed.
2. How would you respond to his request for whole-spine MRI, and how do you structure the next 6 weeks?
Read the worked answer
Respond to the request, don't dismiss it. Acknowledge his worry, explain that more imaging is unlikely to change management and may reinforce the idea that something is seriously wrong, and note that his current imaging already explains his symptoms adequately. Offer to discuss findings with him and, if he remains concerned, involve his physician rather than promising a scan.
Next 6 weeks:
- Education and reconceptualization of pain, with a written plan.
- Graded activity and exposure: start with tolerated bending and lifting tasks, progress toward work-specific demands.
- Sleep and mood screening, with referral as indicated.
- Coordinate with the employer on a graded modified-duty start, with a target date.
- Measure function, not just pain, and review progress at defined intervals.
If there is no functional progress despite this, revisit the plan and consider broader interdisciplinary care.
