How should the effectiveness of IFC therapy for chronic low back pain be evaluated?

• A. Pain reduction (VAS) only
• B. ROM improvement only
• C. Oswestry Disability Index improvement only
• D. Pain reduction (VAS), improvement in Oswestry Disability Index, increased ROM, and patient-reported functional gains

Answer: (D)

Evaluating IFC therapy for chronic low back pain should capture multiple aspects of recovery, not just one aspect like pain. Pain reduction is important, but it doesn’t tell us how pain relief translates into daily function. The Oswestry Disability Index provides a standardized measure of how back pain affects activities of daily living, so improvements there reflect real-world benefit. Increased range of motion shows that physical capability and mobility are improving, which is relevant for functional tasks and overall movement quality. Finally, patient-reported functional gains capture personal, everyday improvements that may not be fully reflected in objective measures but matter greatly to the patient’s quality of life.

Using all four measures—pain (VAS), disability (ODI), ROM, and patient-reported functional gains—gives a comprehensive picture of how IFC therapy is helping, which is why the best choice includes each of these domains. Relying on a single outcome could miss important improvements or lack thereof in other meaningful areas.
