So after an adjustment in many chiropractic offices, adjunct therapies are done as well to compliment the effects of an adjustment. Adjunct therapies, there's many different types. Today we're demonstrating on this unit, EMS, or electrical muscle stimulation. There's also an ultrasound head here as well that we could typically use. So for the areas of the cervical spine or the thoracic spine, basically we're going to get pads set up on the areas that we need to work on. The system goes on, we turn the current up, and the current's going to go through there for about ten minutes give or take and the job of the EMS is basically to promote more of a muscle relaxation. Additionally, if there's people that are in acute levels of pain and there's inflammation on there it helps to flush some of those inflammatory toxins out as well, but primarily if we're using the interferential current, we're really just trying to get those muscles to relax, get them to come down, and reset the stress receptors that are in there that are keeping them wound up real tight. With the ultrasound unit, again we're just going to take the wand. Now we can combo this or we can do them individually and we put some gel on the area in question, we set this for three, four, five minutes. Whatever the case may be and we basically keep this in motion over the area, over the soft tissue and musculature that we're working in. The point of ultrasound is a deep heating therapy. So it just helps again, as you know with heat, helps to just reduce muscle tension in those areas. If someone is very acute we're not going to use this because heat and acute situations don't go well together, but if someone is very chronic or they're sub-acute we can use this to help promote further healing and muscle relaxation. It just compliments nicely, the adjustment.
