Echo, I’ve been using contact mode for over a week now with the rejuvenation preset. My weak ankle is stronger, my problem knee is better and doesn’t pop. My elbow is tighter and doesn’t pop, my rotator cuff seems to be healed. I can move my arm in ways that I haven’t been able to do for three years and I can pick up heavy objects from work which I couldn’t do before. Overall my body feels much more supple and stronger, even my neck and shoulder muscles have relaxed.
