I saw an episode where SN/JF worked with a child who had CP. TBH she wasn't the one with poor behaviour but JF did support the family so the girl with CP got 1:1 time for physio etc and the other girls got special time as they felt pushed aside. I also have seen a few where the children have ADHD, she did put some 'techniques' in place to ease their frustration and helped parents recognise when to 'redirect'.
There has also been some revsited episodes before. I remember watching one with a young girl.
I have seen her talk to children about how they feel about things and then talk about their behaviour. She tells them behaviour is not OK and a better way to deal with it, communicate with parents.
I have to admit I agree that there seems to be a lot of things to implement in some cases which may be wearing/ time consuming but I guess as things improve you can do each of them less frequently and enjoy being a family?
I think ultimatly, as it seems to be proved here, she takes an old fashioned approach. I parent DS in this way and am considered strict. However I expect good behaviour/ manners but for example can allow the freedom.
My friend however hates any mess, hardly ever toys out at hers let alone everywhere but her dc's get away with hitting her and calling her names. 'The little monkeys'. 
I don't agree with all her 'techniques'. I don't do reward charts, if DS is behaving he gets my attention and we play board games etc, if he isn't then I MN will tell him to sort out his attitude and we will play again. Sometimes though he is happy playing games/ watching TV alone.
