Chattanooga’s Cefar TENS is our next generation of handheld TENS device, building on the established technology of the Primo Pro with added features to combine TENS and NMES treatments in one portable unit.

Intended for use by both healthcare professionals and patients, the Cefar TENS combines TENS with NMES to bring pain relief and muscle rehabilitation from the clinic to the home. Patients can begin treatment with the device in a clinical environment under the supervision of a healthcare professional, before continuing their rehabilitation in the comfort of their own home. Simple and easy to use, with a range of compliance features, patients can be confident about taking their treatment into their own hands while their clinician can easily set parameters and monitor their progress.

For healthcare professionals this equals faster recovery times and shorter stays for patients1, less pressure on resources, and less use of analgesics2, therefore patients can benefit from reduced pain, increased mobility, and greater independence.

Altogether, Cefar TENS is more than just a pain machine.

The course was excellent, very enjoyable. I heard terms I’d not heard since I was a student (40 years ago now!). Cliff was terrific, he made it interesting and has a first class manner

Philip Emm

The talk was very informative. I will certainly consider attending future events as I review how we can integrate new modalities into our clinic

Ishmael Beckford

Thanks for organizing a great evening with Cliff. It was extremely infomative and the machines were working overtime this morning!
