Have to say I could not quite believe it..!! I first set eyes on a device (Scenar) via Dr Sanjay Choudhury, about 4 years ago, here in Sussex, I remember I had a dodgy ankle, he used it on me briefly, maybe 5 minutes, I remember at the time being amused, and thought it was a bit cranky!! … but then my ankle healed. I then periodically kept hearing whisperings of Scenar devices through friends that had amazing results from this little gadget. I recently injured my elbow, pretty badly, (after years of punishing gymnastic regimes, and plenty of Yoga) my wrists and elbows are prone to suffer .. my elbow was strained to the point I could not raise my arm, a real effort to even hold my handbag. We sat for a while Helen and I, and Helen began a treatment. I believe the Scenar was on a moderate setting .. pleasantly buzzing away, I guess for around 6-7 minutes. The rest is history, absolutely amazing results, really. My elbow felt significantly better almost instantly, and continued to improve. That evening it was 100% better. What an amazing piece of equipment - portable, versatile, can be used on pretty much anything.. ONE WORD REALLY … PROFOUND
