Lower back pain is perhaps the most common "back pain" experienced by adults.  Symptoms may be caused, or in the least perpetuated within a sedentary office environment.  Sitting for extended periods of time, even with proper support and posture, can aggravate the lower back.  Specialized strokes can be used to target varying types of lower back pain, which can include spasms, dull aches, throbbing, etc.
