Hello i have a question , so i have a tens 7000 , so the modes dont match the models in the video, but is their a range in the hertz that would be preferable im usual at 40hz to target inflamation as ive read research into that range seems to help that the best And also could a small discription of what the modes suggested feel like so i could possibly match it too , examples like constant flow , pulses, kneading, variation in in the strength in waves with rest periods are some mine do , i know their are other models that have intresting patterns to them also . Its a long shot on a 4yr video and im 1st to comment but thanks in advance if someone happens to respond back and have a good day
