Children in the control group received a selected physical therapy program of one hour session, three times per week for three successive months. This program is based on the neuro developmental approach directed toward inhibiting abnormal muscle tone and abnormal postural reflexes and facilitation of normal movement patterns. The postural control was addressed through reflex inhibiting positions using proximal and distal key points of control. Treatment was conducted through a set of therapeutic activities as
follows: approximation, as a proprioceptive training, was applied in a slow and rhythmic manner for upper limbs, lower limbs and trunk to control spasticity and stimulate the joint mechanoreceptors from semi reclined and quadruped positions; training of active trunk extension; facilitation of righting and equilibrium reactions to improve postural mechanisms, through using specific exercises; like tilting at different directions using therapeutic balls and balance board; facilitation of protective reactions by applying fast and large amplitude
stimuli to prompt saving reactions from sitting on the roll. Protective reactions from standing position were promoted by pushing the child to improve the child ability to take protective steps forward, backward or sideways to regain balance. Facilitation of standing from supine and prone positions as well as facilitation of single limb support while standing facing the stand bar. Strengthening exercises for weak muscles particularly
knee extensors, hip abductors and ankle dorsiflexors muscles. Gait training activities were also essential elements
for balance training including; sideway, forward and backward walking between parallel bars in front of a large mirror and walking training using stepper. Gait training at open environment was used by placing obstacles; like rolls and wedges across walking tract. Also, walking training on different surfaces like soft mat, sponge, carpet, or hard surface was used.
