Settings and conduct: The study used a simple randomization method and a double-blind design, with participants blinded to group assignments. Data was collected from demographic data and evaluated at baseline and after six treatment sessions, including pain intensity, pelvic alignment, muscle thickness, and functional performance. Participants/Inclusion and exclusion criteria: The study of chronic low back pain (LBP) in individuals aged18-50 with a BMI of 18.5-30 kg/m², a VAS score of 3-8, and a diagnosis of chronic SIJ syndrome aims to Participants must have stable physical activity and have not had dry needling or electro-acupuncture in the last 6 months.
