Background: Non-specific low back pain (NSLBP) is a major public health concern with significant socioeconomic impact. Among various non-invasive management options, Interferential Therapy (IFT) and Transcutaneous Electrical Nerve Stimulation (TENS) are frequently employed electrotherapeutic interventions, though their comparative efficacy remains underexplored. Aim of the study: To compare the effectiveness of IFT and TENS in reducing pain and improving functional outcomes in patients with NSLBP. Methods: This prospective observational study included 50 NSLBP patients, randomized into two groups: Group A (IFT) and Group B (TENS), each with 25 participants. Pain intensity (VAS), disability (ODI), lumbar flexion range, and patient satisfaction were evaluated before and after 4 weeks of treatment. Result: Both groups showed significant improvement, but IFT demonstrated superior outcomes. Post-treatment VAS scores were significantly lower in Group A (2.8 ± 1.1) than Group B (3.6 ± 1.3) (p=0.02). Similarly, ODI and lumbar flexion improved more in Group A (p=0.006 and p=0.02, respectively). Patient satisfaction was also higher in the IFT group. Conclusion: IFT is more effective than TENS in reducing pain, enhancing mobility, and improving functional status in NSLBP patients. It also yields greater patient satisfaction, supporting its preferential use in clinical practice.
