I have suffered declining health for several years. I have more health issues than most. Recently my husband purchased a Theralumen for his health. Since it was here I decided to try it and see if it would help any of my many issues. I have to say there has been a great improvement to my health. The greatest benefit I can attest to is before using the unit I would have to use a wheel chair when we went out to shop or eat dinner. Since using the Theralumen my strength has increased to the point I am no longer dependent on the wheel chair to get around. What a blessing.
