analyse af årsagen til manglende respons, fx dårlig isolation af de muskler, der skal injiceres, for lav dosis, dårlig injektionsteknik, fikseret kontraktur, for svag antagonist, eventuel udvikling af antistoffer
analysis of the reason for non-response, e. g. poor isolation of the muscles intended to be injected, too low dose, poor injection technique, fixed contracture, too weak antagonist, possible development of antibodies
