This study is testing two ways of using a machine called NexWave to help with lower back pain. The two methods are called TENS (Transcutaneous Electrical Nerve Stimulation) and IFC (Interferential Current). A sham device, which looks like the real one but doesn't work, is also used for comparison. The goal is to see how well these treatments help with pain in people aged 18-70 who have had lower back pain for at least 3 months. Participants will share their pain levels using a scale called Visual Analogue Scale (VAS), where they rate pain from 0 to 100. The study will not include people who have had back surgery, certain spine issues, or use certain medical devices or medications.
- Study duration and visits: Participants must take part in all tests and fill out questionnaires.
- Eligibility: Ages 18-70 with chronic lower back pain; no prior use of similar devices.
- Risks: Not for those with certain health conditions, implants, or pregnant women.
