Hi Lisa. As with any other injury/condition, the answer to your question depends on the etiology of the low back pain. Lower back pain is such a common condition, with so MANY possible causes, that a single answer to your question (‘yes,” or ‘no’) is not really possible. You should first determine the cause of the lower back pain (through a medical consultation) before deciding whether is safe for the person or persons involved.
I hope that this helps.
