Studies have shown that the cycle ergometer exercise improves several parameters, such as muscle strength and endurance, along with torso control in sitting position. However, these results are presented only in a small sample. Studies with the use of cycle ergometer in the population with CP are still scarce and present little information about the physiological effects .Ergometers have been widely used in subjects with CP. Previous studies on children with CP focused on the effect of ergometer on the upper and lower extremities functions. Limited literature is available regarding the effect of arm ergometer on trunk control among this population. The current study will be carried out to investigate the effect of arm ergometer versus stabilization exercises on trunk control, hand grip strength, upper extremities function in children with diplegia.
The purposes of the current study are to:~Investigate the effect of arm ergometer on trunk control, hand grip strength and upper extremity functions in children with spastic diplegia.~Investigate the effect of stabilization exercise on trunk control, hand grip strength and upper extremity functions in children with spastic diplegia.~To compare between the effects of arm ergometer versus stabilization exercises on trunk control, hand grip strength and upper extremity function in children with diplegia.
