Study aim
-
This study is critical not just for increasing our understanding of PLNP, but also for developing novel, evidence-based therapies that might greatly improve the quality of life for those living with this terrible disorder.
-
Design
-
A concealed, experimental, blinded, randomized clinical trial with a control group design of 30 patients enrolled between October 2023 and November 2023 and followed for 4 weeks
-
Settings and conduct
-
This will be conducted at The First People Hospital,Wuhan &trial assesor blind

Intervention groups
-
1. UGIHA Group: Patients in the UGIHA group received acupuncture sessions twice a week for four weeks. A 0.3 mm × 40 mm disposable needle (DongBang Acupuncture Inc., Korea) was percutaneously inserted and advanced to a depth of 15-25 mm into the intervertebral foramen under real-time ultrasound guidance. The needle was then electronically activated to produce heat. Acupuncture points targeted specific regions of discomfort or dysfunction.(13)
2. Control Group: Participants in the control group received non-therapeutic ultrasound therapy sessions twice a week for four weeks. The ultrasound therapy was administered without the application of heat and did not involve needle insertion

Main outcome variables
-
1. Primary Outcome: Pain severity was assessed using a 10-point visual analog scale (VAS) at baseline, after the 4-week intervention period, and during follow-up visits.
2. Secondary Outcomes: Serum levels of IL1β, TNF-α, and PGE2 were measured before and after the treatment period using established biochemical assays.
