By just putting these words in Google I found one small abstract about this screening. Apparently it is a psychological assessment and only in German.
To find out more I suggest you Google some more and maybe ask the colleagues at
ZVK.ORG - Deutscher Verband für Physiotherapie - Zentralverband der Physiotherapeuten/Krankengymnsaten (ZVK) e. V. = the German Society of physiotherapy.
If it is a screening that can be used by physiotherapists, I suggest you look up the assessments being used in the english speaking world as well.
lots of information about that on this forum and at CanChild Centre for Childhood Disability Research
Good luck......
