Análisis de la sedestación y eficacia del asiento pélvico moldeado en escolares con parálisis cerebral

Resum

Introduction The use of technical devices is an improvement in the sitting postural control for children with motor disabilities. Objective Analyze the relationship between stability in sitting and gross motor function, and evaluate the effectiveness of pelvic molded seats made out of plaster in children with cerebral palsy (CP) in school setting. Material and Methods. 139 children with CP enrolled at schools in the Region of Murcia were evaluated with the Level of Sitting Scale (LSS) and the Gross Motor Classification System (GMFCS). In addition, 12 children received physiotherapy treatment with pelvic molded seats, assessing the pelvic tilt and rotation, lateral deviation of the trunk, the gross motor function [Gross Motor Function Measure (GMFM)] and balance [Test Coordination and Balance (TCE ) designed for this study]. Results Relationship between levels of LSS and GMFCS (r:-0.86, p <0.01 ) was found. The use of pelvic molded seat improved pelvic tilt (Z:-2.831; p:0.01) and rotation (Z:-2,014; p:0.04) of the pelvis, lateral deviation of the trunk (Z:-2.20; p:0.03) and the balance in the sitting position ((t (10):-6.167; p <0.01). In 83.3% of cases, gross motor function was better at study end. Conclusions In children with CP, there is an association between the GMFCS and the LSS, and relationship between the stability in sitting and the ability to walk with or without technical devices. The position of the pelvis, trunk and balance in sitting posture, improve with the application of pelvic molded seats. Keywords Orthotic Devices, Motor Skills, Postural Balance, Cerebral Palsy
