Trunk Somatosensory Function, Trunk Control, and Thoracic Kyphosis in Children With Spastic Cerebral Palsy

Overview

This observational study aims to investigate the relationship between trunk somatosensory function, trunk control, and thoracic kyphosis in children with cerebral palsy. The main questions it seeks to answer are: * Is there a relationship between trunk somatosensory function and trunk control? * Is there a relationship between trunk somatosensory function and thoracic kyphosis? * Is there a relationship between trunk control and thoracic kyphosis?

Cerebral palsy (CP) is a heterogeneous disease group that occurs due to non-progressive lesion in the developing fetal or infant brain and causes constant and permanent impairments in movement, posture, and motor function. Sensory, perceptual, cognitive, communicative, and/or behavioral disorders, epilepsy, and secondary musculoskeletal problems may accompany motor disorders, the primary symptoms in CP. CP is one of the most common physical disabilities in childhood, with a reported prevalence of approximately 2.11 per 1,000 live births. Children with CP can be classified according to the type of motor impairment (physiological), the parts of the body affected (topographical), the etiology, the associated disorders, the neuroradiological findings (neuroanatomical), the therapy needs (therapeutic) and the functional abilities.The Surveillance of Cerebral Palsy in Europe (SCPE) classified CP as spastic, ataxic, and dyskinetic according to tone and dominant abnormal movement patterns. Spastic type is the most common form (70%). Children with CP exhibit poor postural control due to abnormal muscle tone and movement patterns. This dysfunctional postural control causes limitations in gross motor skills such as balance and walking, upper extremity activities such as reaching, and oral-motor activities such as eating, swallowing, and speaking. Weak or inadequate postural control affects functional performance, participation in recreational and social activities, and society in children with CP. The trunk is the reference point for postural control during stabilization and orientation. It is essential to ensure postural alignment, maintain postural balance, and interact with the environment (performing target-oriented activities). Trunk control refers to maintaining an upright posture, adjusting weight bearing, and performing selective movements while keeping the body's center of gravity within the support surface. In summary, trunk control is responsible for the stability and selective movements of the trunk. It is a precursor for ensuring optimal, targeted, selective, and dissociated movements of the head and extremities. Weak or inadequate trunk control is the basis of the limitations in the functional movements of children with CP. Although the pathophysiology is not progressive in CP, musculoskeletal disorders such as increased stiffness of spastic muscles, deterioration in spinal alignment, and joint contractures are observed with age. Weakness in trunk muscles in children and adults with CP may cause increased trunk extension and impaired spinal alignment in the sagittal plane in the sitting position. Impairment of spinal alignment negatively affects the motor function and activities of daily living of children with CP. It has also been found that the pathological alignment of the trunk and pelvis is associated with postural balance in children with CP. Motor problems are often accompanied by sensory disorders in CP. Sensory disorders may also cause motor dysfunctions since sensory information for movement is impaired in children with CP. 90% of children with CP have sensory dysfunction. Recently, there has been an increasing interest in somatosensation among the senses in CP. The somatosensory system includes all peripheral and central components involved in the transmission and processing of sensory information from the superficial or cutaneous receptors and/or the musculoskeletal system and is closely related to the motor system. Somatosensory can be classified as tactile, proprioceptive, and pain sensation. It has been reported that somatosensory disorders are more common (97%) in children with unilateral CP. Somatosensory deficits in CP have been associated primarily with damage to the developing brain and secondarily with motor disorders. Studies have also shown that motor impairments and somatosensory deficits are associated with children with CP. The literature shows that the relationship between somatosensory deficits and motor disorders in children with CP is primarily studied in the extremities (especially the upper extremities). A study evaluated trunk somatosensory function and motor impairments in children with CP. Only trunk proprioception (trunk position sense) was evaluated in this study among the somatosensations. A more comprehensive study, including tactile and pain sensations, has yet to be found. This study examines the relationship between trunk somatosensory function, trunk control, and thoracic kyphosis in children with CP.
