Can gentle electricity make weak knees stronger? New 2025 Study – University-backed Evidence

Health Research Digest with Leo and Eva

Tired of weak, sore knees that slow you down?A brand-new 2025 study just found a simple way to help you move stronger — without extra pain. Researchers reviewed 11 clinical trials (571 people) with front-of-knee pain to test if adding Neuromuscular Electrical Stimulation (NMES is a niche of EMS) to normal exercise could make a difference. Here’s what happened:After six weeks or more, people moved easier and felt stronger.Their knee function and quadriceps strength improved more than exercise alone — but pain levels stayed about the same.That means EMS helps you move better, not hurt less. Why it matters:If stairs, chairs, or squats make your knees wobble, this shows how gentle electrical pulses can “wake up” sleepy muscle fibres you can’t easily train by willpower.Think of EMS as a silent coach helping your legs work smarter. Study details:Published in BMC Musculoskeletal Disorders (2025)Title: Effectiveness of Neuromuscular Electrical Stimulation on Pain, Function and Quadriceps Strength in Adults with Patellofemoral PainAuthors: Abdelhamed et al.DOI 10.1186/s12891-025-09029-5 Quick summary:• Function ↑ after 6 weeks of EMS + exercise• Strength ↑ (0.53 effect size)• Pain ↔︎ (no extra change)• Evidence = very low certainty → needs better trials Takeaway:EMS isn’t a magic cure — but it helps you build strength faster so daily life feels lighter again. Imagine carrying groceries or taking stairs without that stiff ache. See the full digest + research link here: http://bit.ly/47jJ0N0
