Spastic Cerebral Palsy (CP) is the leading cause of upper motor neuron syndrome (UMN) in children. The primary factors contributing to motor behavior disorders in these children are impairments in motor control and muscle strength. These impairments result in changes in muscle growth and hinder the development of motor skills, leading to reduced muscle force generation and decreased flexibility. Spastic cerebral palsy is the most prevalent type, affecting 77% of individuals with CP, and is caused by damage to the motor cortex and pyramidal tracts. The motor cortex is responsible for transmitting voluntary movement signals from the brain to the muscles. Characteristics of spastic cerebral palsy include stiff muscles (hypertonia), which can cause jerky and repetitive limb movements (spasticity). Additionally, individuals with CP often have difficulties in processing somatosensory and proprioceptive information. Proprioceptive training refers to interventions aimed at enhancing proprioceptive function to ultimately improve motor performance, a concept that has been explored in studies focused on sports injuries. In this study, we will utilize two proprioceptive exercises-rhythmic stabilization and ball balancing-to promote functional improvement in the upper extremities of children with spastic CP.
