Allthoug hemiplegics aquire a cosidrable amont of strength in there D.F , evertors and hip flex. still are not able to use them like normal human beings. P.N.F helps to re-educates funcutional movements . It has been mentioned at several places that brain appreciates mov and not specific muscle actions. I have a hemiplegic pt. who owns a good muscle power but fails to perform simple tasks in functional positions. For example: he is able to supinate well but can not do so with an extended elbow.
