Hi anoodyPT

now in reassessment her pain become 5/10 and AROM: there is little limitation in extention and (R) lateral flexion and she able to walk and stand up to 30 min
but still her burning and electrical sensation didn't improved
what can i do else for her
Sorry I didn't read this when I responded above - based on this you have achieved a significant improvement in pain and disability so well done and sounds like you are at least partly on the right track. This would tend to add weight to the movement impairment syndrome idea and possibly also the lumbar stenosis. How many treatments have you given her and over what time?

The Williams exercises (very old system but interesting to see it is in use still) is probably quite similar to Shirley Sahrmanns approach for and extension problem of the lumbar spine and both would improve the problem. However I think Sahrmann's concept is more developed and the emphasis is on permanently changing the muscle imbalance by improving both motor control and appropriate strengthening and lengthening. William's approach is relatively imprecise in this way.

I still think you should go back to your diagnosis however. Particularly ruling out red flags, possibly getting further imaging if warranted, and to sharpen up your differential diagnosis. Understanding the nature of the burning and electrical symptoms is important. And what about her muscle strength now? This maybe important to ensure you can get further improvement.
