摘要

Purpose

Little information exists on the potential differential response to functional restoration between non-specific chronic low back pain (NSCLBP) individuals with and those without Modic type 1 changes. Therefore, this case-control study investigated the response profile of NSCLBP patients with and without Modic type 1 changes undergoing functional restoration.

Methods

The present study included patients participating in a functional restoration program (day-hospital program lasting five weeks) at a French tertiary care center from 2009 to 2019. Each case with Modic type 1 changes was matched to one to two controls without Modic type 1 changes by sex, working incapacity, and lumbar spine surgery history. The primary effectiveness outcome was the Quebec Back Pain Disability Scale (QBPDS) score (0-100, with higher scores indicating higher disability). There were multiple secondary outcomes, such as subjective improvement and return to work.

Results

The study included 83 patients (cases: median [IQR] age 47.8 [11.6] years, 77.4% women; controls: median [IQR] age 46.0 [16.2] years, 75.0% women). At three months, there were no statistically significant differences between cases and controls in the QBPDS score (34.0 versus 31.5), subjective improvement (67.7% versus 69.2%), return to work in those who were not working at the inclusion (72.7% versus 52.6%), and the consumption of different analgesics.

Conclusion

The response profile of NSCLBP adults undergoing functional restoration did not statistically differ between the groups with and without Modic type 1 changes. These findings suggest that patients may benefit from such a program irrespective of their Modic type 1 status.
