Alkhaldi hospital st by the 3rd circle has many stores on both sides of the street that has all kind of body braces and walkers and hospital supplies, you can see them as you are driving through, i got my back brace for my herniated disc for 30 JOD from there
There isn't any. No driving school in Jordan has an English speaking teacher,but if the student has a foreign driving licence he can just submet it along side his residence card and get a Jordanian licence(expt Italians) if the student needs lessons, his best bet is getting someone who speakes English to teach him then get 2 official lessons in the DMV and then going through the test. The testers don't speak English so you would need a translator.
I am not sure if they have it, but @Cozmo. Has everything! Or try to buy it online at amazon, you could buy from amazon through CashBasha they will come to you collect the money and then a week later they will bring your purchase to you.
