NCT ID NCT06744036
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a mild electrical current (interferential current) to a standard exercise program can further reduce pain and improve function in people with knee osteoarthritis. 138 adults aged 40-75 with knee pain will be split into three groups: exercise only, exercise plus real electrical stimulation, or exercise plus a placebo device. The treatment lasts 8 weeks, and participants are followed for another 4 weeks to see if any benefits last.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
interferential current (a type of electrical stimulation)
What this could lead to
If it works, this could provide a simple, drug-free way to boost the pain-relieving and function-improving effects of exercise for people with knee osteoarthritis.
What could go wrong
This is a small, early-stage trial. The added benefit of interferential current may be small or no better than placebo. Results may not apply to all people with knee osteoarthritis.
