Suggest Treatments For Muscle Contractions And Rotation Of Pelvic Girdle

My disabled neice has muscle contracture in both legs from hips to ankles.

her entire pelvic girdle is rotated to her right which seems to have straightened her lumbar curve. She is no longer able to weight bear and has a pressure area at the lumbar sacral area of the lower back that cycles through a healing and then breaking down process. I think there is some nerve inpingement on the right side as sensations in her right foot areabnormal. I have had her GP prescribe panadol osteo 2 tabs 3 times a day and 200mg of celebrex for the constant pain. What treatment options are there to resolve any or all of these problems in order to get her back on her feet again?
