Response to functional restoration in non-specific chronic low back pain with Modic type 1 changes

Area of Science:

• Orthopedics
• Rehabilitation Medicine
• Pain Management

Background:

• Non-specific chronic low back pain (NSCLBP) is prevalent, with Modic type 1 changes potentially influencing treatment response.
• Limited data exists on how Modic type 1 changes affect functional restoration outcomes in NSCLBP patients.

Purpose of the Study:

• To investigate the differential response to functional restoration in NSCLBP patients with and without Modic type 1 changes.
• To compare functional restoration outcomes based on the presence or absence of Modic type 1 changes.

Main Methods:

• A case-control study matched NSCLBP patients with Modic type 1 changes (cases) to those without (controls).
• Participants underwent a five-week day-hospital functional restoration program.
• Outcomes included the Quebec Back Pain Disability Scale (QBPDS), subjective improvement, and return to work.

Main Results:

• No statistically significant differences were observed between cases and controls at three months in QBPDS scores (34.0 vs. 31.5).
• Subjective improvement rates (67.7% vs. 69.2%) and return-to-work rates (72.7% vs. 52.6%) were also comparable.
• Analgesic consumption did not differ significantly between the groups.

Conclusions:

• Functional restoration outcomes for NSCLBP adults do not statistically differ based on Modic type 1 changes.
• These findings suggest that functional restoration programs can benefit NSCLBP patients irrespective of Modic type 1 status.
