About this trial
This clinical trial aims to check the safety and efficacy profile of pulsed radiofrequency (RF) neuromodulation combined with leukocyte-rich platelet-rich plasma (PRP) injections for the treatment of refractory low back pain due to multifidus dysfunction. The trial will compare two groups: one receiving standard physical therapy and the other receiving pulsed RF neuromodulation and physiotherapy.

Treatments tested in this trial
Pulsed RF Neuromodulation
Procedure/SurgeryRF neuromodulation will be applied to the L2 and L3 segments bilaterally. Each segment will receive treatment for 6 minutes, either sequentially or simultaneously on both sides.
Leukocyte-Rich PRP Injection
Biological/VaccineLeukocyte-rich PRP will be prepared from the patient's blood and injected into the multifidus muscle at the L2 and L3 levels.
Physiotherapy Alone
Procedure/SurgeryStandard physiotherapy regimen tailored to each participant's needs. This may include exercises to improve flexibility, strength, and endurance of the back muscles, as well as education on posture and body mechanics.
