Non-specific low back pain (NSLBP) is a prevalent condition affecting up to 84% of the adult population, frequently progressing to chronicity and diminishing quality of life. Interferential current (IFC) therapy has demonstrated effectiveness in alleviating musculoskeletal pain using 2KHz and 4KHz carrier frequencies, though conventional treatment protocols require sessions of 30 minutes or longer. The integration of IFC with ultrasound technology enables deeper tissue penetration and significan
