Common conditions that are helped by the percussor are: pain, swelling, congestion, muscle spasm/hypertrophy, and ischemia (poor blood supply). For more information, see below.
When the percussor is applied to one’s body, it feels like a vibrator or massager. However, there is a vast difference. A vibrator or massager is able to penetrate only a few millimeters into the body. The percussor transmits energy literally through the body. If your skin, muscles and fat were removed from your body, then one might say, well, now all you have left is just the skeleton right? Wrong! If you remove the skin, the fat, and the muscles, then you would see a covering from the top of the head to the bottom of your feet that resembles something like your pajamas. It literally covers your whole body with some openings at your joints so that movement is not restricted. This covering is called the basement membrane fascia. It is dense and strong but yet allows motion of your body. It literally holds your skeleton together. It cannot contract like your muscles but when traumatized as in an automobile accident, sports injury, or in a slip and fall injury, it will tighten and often will stay in a tightened state permanently. When this happens, the deep tissue therapists will attempt to release the constriction with deep pressure sometimes using their elbows. This can be quite unpleasant to the person being worked on. However, the energy from the percussor will penetrate all the way to and even through the basement membrane fascia in just a few seconds. This restores the normal mobility of the fascia and the patients report that the percussor feels soothing and relaxing, some even saying they could easily go to sleep.
