Physical restraints or restorative practices

Yet more reports of use of physical restraints in YOIs and prisons, from The Guardian website.  You have probably seen them.  These are just 3 of them.
Has the RJC impressed on NOMS the fact that in many cases physical restraint need not be used at all, if staff were trained in restorative practices or non-violent communication?  It makes me think of John Howard’s comment, as true now as in 1792. that there is ‘a way of managing some of the most desperate, with ease to yourself, and advantage to them’.  He might have added ‘and it’s called restorative practice’ !
There was another article, which I now can’t find, about how in Spain they have educators rather than prison officers in young offender institutions, and don’t need physical restraints.
