Coming back to the backache of your 60yr patient,check if she is better in supine or prone position. She has a loading problem & gets better in unloaded position. She seems to be bad on her core muscles & an attack of chicken gunya gave her general weakness which probably is putting a load on her posterior disc. If prone position is better, get her to do the mckenzie protocols for back. Sometimes if there is a huge obstruction due to the disc, patient may not tolerate prone initially. In such a case you may have to give a small cushion under her abdomen and then gradually initiate her to pressup.
Nailing her pain would be very easy. Do give me the info.
