The Impact Of Core Stability Exercises On Standing , Functional Balance And Gait In Diplegic Cerebral Palsy Children

Cerebral palsy (CP) could be a cluster of disorders that have an effect on the event of movement and posture,inflicting activity limitation, and nonprogressive disturbances that occurred within the developing fetal or child brain.The main therapeutic goals for children with CP are the performance of functional activities and walking.

Children with CP have a limitation with activities due to the existing impairments in independent walking, climbing stairs, running, or walking over uneven surface .Functional limitation of children with CP may have various degrees due to loss of axial control with an imbalance of their movement .Balance has been defined as the elements of postural control that allow a child to safely perform everyday tasks . Poor balance control is one of the most contributing factors for poor gait and reaching movement because the maintenance of stability is critical to all movements . Children with CP have defects in postural mechanisms, including righting and equilibrium reactions, antigravity mechanism, proximal stability, and postural fixation . Diplegia is amongst the most widely recognized clinical subtypes of Cerebral Palsy (CP). It is used when the motor impairment is milder in the upper limbs than the lower limbs. Most children have major weakness in the trunk and hypertonic limbs .Diplegia is characterized by increased muscle tone with difficulty in relaxing. Active movements are slow and stiff with abnormal patterns. Lower limbs are more affected than upper limbs. Head and neck are unaffected but there is weakness and limited rotation of the trunk . Children with CP may experience a range of functional limitations as a result of loss of trunk control and movement imbalance. Balance is defined as the postural control elements which enable a child to safely execute daily tasks.Because maintaining stability is necessary for all movements, low balance control is one of the extreme common causes of unsafe walking or reaching function . So core stability training is preferred to maintain position and movement of body core. Stability training involves the abdomen muscles and pelvic and shoulder muscles, which maintain postural alignment and allow movements of extremities. Postural control is mainly for motion and depends on these muscles for stability and endurance. Components of core stability include strength, endurance, balance,nd the related activity of the back, abdominal, and pelvic muscles . The core muscles act like one block to keep the body stable during static state and with extremity motion . CP children lack the ability to distribute the load, that is, body weight, appropriately during static balance and transfer the body weight adequately from one supporting limb to another during dynamic balance tasks . Children with diplegic CP are characterized by impairment of motor control in the lower extremities more than in the upper extremities.

Statement of the problem This study will be conducted to answer the following research question:Is there any significant effect of core stability exercises on standing , balance and gait in Diplegic cerebral palsy children ? Purpose of the study The purpose of this study is to study the effect of core stability training on standing, balance and gait in spastic diplegic cerebral palsy children.

Significance of the study Spasticity, muscle contraction, bony malformations, loss of selective motor control, and muscle weakness are potential factors that interfere with normal gait patterns in diplegic CP. Recent studies have found that muscle weakness limits motor function in children with CP more than spasticity. Therefore, strengthening weak muscles is es-sential for spasticity management to improve the func-tion of diplegic CP.Balance disorder is a serious problem for children with diplegic CP, and this can make it difficult to achieve and maintain equilibrium. Children with diplegic CP have reduced neuromotor perceptual func-tion, inadequate stance stability in different sensory settings, slow anticipatory response, and inaccurate pre-paratory activation.

The term of "core stability" explains the capacity to control the position and movement of the central portion of the body. Core stability training targets the muscles deep within the abdomen that attach to the spine, pelvis and shoulders, that help in the preservation of proper posture and provide the basis for movements of extremities in a coordinated manner. Spinal stability is essential for the production of movement and relies on the core muscles to acquire sufficient strength, power, and endurance .The core has illustrated by researchers as a "power-house" for initiating limb movement or as a double-walled cylinder or box in which the abdominals act as the front of the house, the paraspinals serve as the back, the diaphragm serves as the roof, and the musculature of the hip girdle and pelvic floor create the 2 basement of the house.
