thanx humera for u r detailed reply.i too agree with esterduru that child shoould be facilitated.and yes humera couldn't we term that child as dynamic dystonic rather than dynamic spastic as spasticitiy is present in antigravitiy muscles and many factors lead it to increased.u initially define Wikipedia reference-linkdystonia in u r rply is static one as child stuck in fixed posture and couldn't move out of it while dynamic dystonia comes with movement.the child i have mention when does reach out with right hand his left hand goes in aduution,internal rotation from shulder flexed from wrist and elbow as well adduction of thumb and also his mouth opens.it's more like assosiated reactions.the main problem i m facing in child is of transition is very poor.he has learned to roll nothing alse in transition his trunk is so flaby specially abdominals that he can't even assume keel standing position with support.and yes humera as u fing difficulty in description better that u include images here...thanx again for u r kind rplies.tc
