The BioPak is a computer program that we use to measure muscle activity of the head and neck. We place electrodes on the different muscles we want to evaluate and then we can measure how much the muscles are being used. By measuring the muscles, we can determine if your headaches, neck aches, sore jaw are all related back to your jaw! The more the muscles have to work, the more likely you are to have issues! Once we know where the problems are, we can then create the orthotic to re-balance the muscles to relieve this.
