Effectiveness and Safety of Pharmacopuncture Therapy for Chronic Low Back Pain: A Protocol for a Pragmatic Randomized Controlled Trial.

PURPOSE

Chronic low back pain (LBP) is a common musculoskeletal disorder that affects everyday life; moreover, it occasionally causes disability and increases medical expenditure. This pragmatic randomized clinical trial aims to investigate the effects of pharmacopuncture on chronic LBP by comparing the effectiveness of pharmacopuncture and physiotherapy strategies.

PATIENTS AND METHODS

In this two-armed, parallel, multi-center randomized controlled study, the participants will randomly undergo 10 sessions of pharmacopuncture therapy or physiotherapy over five weeks based on the randomization outcomes. The primary outcome will be the numeric rating scale (NRS) score of LBP. The secondary outcomes will include the NRS score of radiating leg pain, visual analog scale (VAS) score of LBP and radiating leg pain, Oswestry disability index, the Korean version of the Roland-Morris disability questionnaire, patient global impression of change (PGIC), short Form-12 health survey version 2, and 5-level EuroQol-5 dimension (EQ-5D-5L).

CONCLUSION

This protocol aims to examine the comparative effectiveness of pharmacopuncture, which is a widely used therapy in Korean medicine, with respect to the standard therapy through a pragmatic randomized controlled trial to present useful data to facilitate clinical or policy decision making.
