So, for immediate relief from back pain, lay down on your back on a bed, with your head just off the edge of the matress. Bend your knees and rest your feet flat against the mattress. This realigns your spine and lets gravity pull it into place, and relaxes the muscles, where the pain most often occurs. It's best to do it on a level, soft surface, because it will have a small bit of give but will keep your spine straight.
You can do it without hanging your head off he edge, however the relief will not be immediate. Do not do it on the floor or any surface that doesn't have give to it.
While in this position, with her knees bent and her feet against the ground, she can try moving her legs together from side to side /slowly/. The motion should be fluid and she shouldn't stop in between. Try not to do any more than ten "sets" of this, because you don't want to fatigue the muscles. That's good for lower back pain in the long run.
Heating pads also help a lot.
