The Beurer EM-29 2-in-1 Knee and Elbow TENS is a wearable cuff designed to relieve pain in either the knee or elbow using Transcutaneous Electrical Nerve Stimulation (TENS). A single universal cuff adjusts to fit both joints, so one device covers two treatment areas without needing separate accessories.
The cuff uses wear-free contact electrodes made from conductive carbon material, so only a little water is needed for good skin contact — no gel or replacement electrodes required. With 4 pre-programmed applications, continuously adjustable intensity, and a removable control element with an LCD display and belt clip, the EM-29 is built for comfortable, everyday drug-free pain management at home or on the move.

Frequently Asked Questions
Can the same cuff be used on both the knee and the elbow?
Yes, the EM-29 uses a single universal cuff that adjusts with a hook-and-loop fastener to fit circumferences of approximately 25 to 70 cm, covering both knee and elbow use without needing a separate accessory for each.
Do I need gel pads or replacement electrodes?
No, the EM-29 uses wear-free electrodes made from conductive carbon material, so a little water is all that’s needed for good skin contact before each session, with no ongoing cost for gel pads or electrode replacements.
Can I move around while using the EM-29?
Yes, the control element is removable and comes with a belt clip, so you can attach it to your clothing and move around during treatment rather than needing to stay seated for the whole session.
Is the EM-29 safe for people with a pacemaker?
No. This device must not be used by people with a cardiac pacemaker or other implanted electronic device, and it should also be avoided during pregnancy or by people with epilepsy or cardiac arrhythmias.
How does the EM-29 differ from Beurer’s other TENS cuffs, like the EM-27?
The EM-27 is designed specifically for the ankle, with a cuff sized for approx. 18–31 cm circumference, while the EM-29 is a 2-in-1 cuff designed to fit both the knee and elbow at a larger circumference range of approx. 25–70 cm. Both share the same wear-free carbon electrode design, 4 pre-programmed applications, and removable wearable control element — the difference is simply which joint (or joints) the cuff is shaped and sized to fit.
