The role of visual stimuli on standing posture in children with bilateral cerebral palsy

摘要: In children with bilateral cerebral palsy (CP) maintaining a standing position can be difficult. The fundamental motor task of independently is achieved by an interaction between the visual, somatosensory, and vestibular systems. CP, disorders are commonly accompanied sensory perceptual disturbances. Our aims were to examine influence visual stimuli on posture in relation ability. Three dimensional motion analysis surface electromyography was recorded describe body position, movement, muscle activity during three tasks: self-selected while blindfolded, attention-demanding task. Participants twenty-seven typically-developing (TD) 36 which 17 required support for (CP-SwS) 19 stood without (CP-SwoS). All CP more flexed than TD children, even pronounced CP-SwS. While CP-SwS group further their hips knees, increased knee extensors. contrast, CP-SwoS maintained same but calf activity. During task, still head positions less Visual input important maintain position. Without who dropped into crouched somatosensory systems alone could not provide enough information about space cues as reference frame. support, intensified stimulus enhanced ability quiet It may that impairments major contributors difficulties stand erect CP.
