Effectiveness Of Combination Of Interferential Current (Ifc) Intervention And Core Stability Exercise In Reducing Pain And Improving Functionality In Patients With Non-Specific Lbp

Abstract

Non-specific-low back pain (LBP) is a highly prevalent musculoskeletal disorder and a leading cause of global disability, characterized by pain, postural imbalance, and functional limitations. Interferential current (IFC) effectively reduces pain through medium-frequency electrical stimulation, while core-stability exercises enhance postural control and lumbopelvic stability. However, the effectiveness of combining IFC with core-stability compared with transcutaneous electrical nerve stimulation (TENS) plus core-stability has been rarely examined. This quasi-experimental pretest–posttest control-group study compared the two combinations in 100 patients aged 20–60 years with Non-specific-LBP, randomly allocated to IFC+core (n=50) or TENS+core (n=50). Interventions were delivered three times per week for two weeks. Pain intensity was measured with the Visual Analogue Scale (VAS) and function with the Oswestry Disability Index (ODI). Paired and independent t-tests were used (α=0.05). Both groups showed significant improvements on VAS and ODI; greater reductions in pain and disability occurred in the IFC+core group (p<0.05). These findings support integrating IFC with core-stability exercises in Non-specific-LBP rehabilitation.
