A postural perturbation refers to unexpected change in conditions that upsets the body's harmony and displaces its posture. These perturbations can be sensory in nature, such as vestibular perturbations resulting from electrical stimulation, visual perturbations caused by a moving room or graphical images, or somatosensory perturbations caused by muscle vibrations. The body's reactions to these sensory perturbations may be based on the perception of instability rather than actual imbalance. Trunk control plays a vital role in various aspects of daily life, including balance, walking, and overall functional abilities. Children with cerebral palsy (CP), who experience limitations in their ability to move, often expend more energy compared to their healthy peers.

This study will be randomized clinical trial used to compare the effects of Perturbation and trunk control training in children with Cerebral Palsy. Subjects meeting the predetermined inclusion and exclusion criteria will be divided into two groups using lottery method. Pre-assessment will be done using Berg balance scale, functional Independent measures and TUG test as objective measurements. Subjects in one group will be treated using Perturbation therapy and the other one will be treated with Trunk control training. Both groups had three treatment sessions per week, for 4 weeks, and the total time for every session was about 30-45 minutes. A postural perturbation refers to unexpected change in conditions that upsets the body's harmony and displaces its posture. These perturbations can be sensory in nature, such as vestibular perturbations resulting from electrical stimulation, visual perturbations caused by a moving room or graphical images, or somatosensory perturbations caused by muscle vibrations. The body's reactions to these sensory perturbations may be based on the perception of instability rather than actual imbalance. On the other hand, "mechanical perturbations" physically displace the body segments, potentially leading to a shift in the overall center of mass or actual imbalance. Even small displacements of a single body segment, like the head, can elicit minor muscle responses throughout the body

Inclusion Criteria:

• Kids that suffer from cerebral palsy.

Exclusion Criteria:

• Individuals suffering from sensory, proprioceptive, cognitive, and perceptual impairments, as well as those with contractures.
• Any neurological disease that impairs balance, including orthopedic disorders
• Individual experiencing seizures and has undergone any prior surgical treatments.
