They received a physiotherapy program

They received the same program given to control group (A) in addition to isokinetic resistance training of the less affected upper limb for shoulder abductors in concentric mode at the angular velocity of 180 degree/ second

For two consecutive months, the children in control group underwent a physiotherapy program for 60min/ three sessions each week: it was based mainly on the neurodevelopment technique, directed toward inhibiting abnormal muscle tone facilitating normal patterns of postural control and hand functions training program

Isokinetic dynamometer was used to measure the concentric isokinetic shoulder abductors peak torque in Newton- meters and average power at an angular velocity of 180 degrees per second in concentric mode with gravity adjustment

It was used to measure the ability of the child to perform the reaching skills. It was used to determine the level of performance and functional improvement in reaching skills. Each child was seated in front of a table, in a chair adjustable to his or her height. They were appropriately fitted and supported to avoid any substitution movement from the child's trunk. The target was positioned on the top of the table, beside the child. The child's elbow was passively placed at full extension and the writ in natural position. Each trail of the reaching task was begun with the child's arm straight and parallel to the patient's trunk. The child was asked to make accurate reaching to touch the target by the affected arm when the examiner gives the command.
