New research shows that the pain signal may be simply an "electrical leak" from an ion channel. As previously written there is a connection between the opening and closing of ion channels and electrical polarity charges. The new finding by a team of scientists at KU Leuven indicates the actual pain message is electrical and is short circuited due to chemical changes in the ion channels. The ongoing research is showing the chemical and physical relationship of pain and electrical polarities.
In the MedFaxx Functional Restoration (see video below Yoga back pain exercises) program it's necessary to exercise, as well as use interferential therapy, to achieve the best results for chronic back and neck pain.
Here is a video on back pain exercises by Lillah Schwartz, using very good Yoga exercise techniques one can do in the home to help with chronic back and neck pain.
This video was originally done as a tone up for abs video but the same exercise principles apply to diminish back pain, increase range of motion and blood flow to the back.
