Lets look at a typical example. A person has sustained a lower back injury while lifting a heavy object. While it may be a very common injury, such cases can be quite difficult to diagnose. It could be an injury of the disc, bone, ligaments, muscles or nerves - but normally, several of these at once. And naturally, the diagnosis guides the therapy. So if it is unclear exactly which structures are affected, treatment can be somewhat in the dark. What eventuates is a medical roundabout, as mentioned above. The patient ends up frustrated and disenchanted because they are in pain, and seemingly no closer to knowing why. If portable electrotherapy is used at all, it is most commonly a last resort. (Even so, it still works in 30% of cases in which every other single therapy has failed!)

On the other hand, were the patient given a portable electrotherapy machine on day one of the injury, a world of difference could be made. From the outset, the patient would have a means of reducing pain that would not cause any side effects (unlike prescribed pain killers). For those experiencing the harmful secondary effects of medications, this in itself is a leap in the right direction.
