Effectiveness of Transcutaneous Electrical Nerve Stimulation and Interferential Current in Chronic Neck Pain

Brief Summary

The aim of this study was to determine and compare the efficacy of transcutaneous electrical nerve stimulation (TENS), interferential current (IFC), and sham therapy in patients with chronic neck pain. A total of 57 patients diagnosed with chronic mechanical neck pain were included in the study. Patients were randomized into three groups. Each group received 10 sessions of physiotherapy over a two-week period: one group received conventional TENS, one group received IFC, and one group received sham therapy. Pain was assessed using the Visual Analog Scale (VAS), disability and functionality using the Copenhagen Neck Disability Index, quality of life using the SF-36, depression using the Beck Depression Inventory (BDI), and pain characteristics using the SF-McGill Pain Questionnaire.
