 - Background
This study was the development of a protocol for the comparison between the efficacy of non-pharmacological and pharmacological treatment approaches for lumbar disc herniation in a pragmatic environment to obtain real-world based study data.
Methods
The protocol sets out a two-armed, parallel, multicenter pragmatic, randomized-controlled trial (RCT) which will be conducted in four spine specialist hospitals in Korea to determine cost-efficiency.
Results
The study will enroll 36 participants and allocate patients into either the non-pharmacological treatment group or the pharmacological treatment group in a 1:2 ratio. Patients must have evidence of disc-related disease diagnosed using MRI, as well as having lower back pain or radiating leg pain (numeric rating scale score ≥ 5). The treatment will last for 8 weeks with a 26-week follow-up. The primary outcome will be measured using the Oswestry Disability Index score from Week 9. Secondary outcomes related to lower back pain and radiating leg pain will be measured using the scores from the numeric rating scale, the visual analogue scale, the European Quality of Life 5 Dimensions 5 Level Version), the 12-item Short Form Survey, and the patient global impression of change.
Conclusion
This is the first protocol for a pragmatic RCT evaluating the efficacy, safety, and cost-efficiency of non-pharmacological and pharmacological treatment strategies in a clinical setting. Following the basis of this protocol, RCTs may play an important role in establishing guidelines for treating radiating leg pain and lower back pain and provide effective information to clinicians in practical settings.
