The Effect of a Soft Lumbosacral Body Brace Supporting Physiological Lordosis on Postural Control and Walking Speed in Children With Cerebral Palsy

The aim of this study is to investigate the effect of soft lumbosacral body braces on postural control and walking speed in children with cerebral palsy.

Hypothesis 1: Soft lumbosacral orthoses that support physiological lordosis in children with cerebral palsy improve postural control. Hypothesis 1: Soft lumbosacral orthoses that support physiological lordosis in children with cerebral palsy correct posture. Hypothesis 2: A soft lumbosacral body corset increases walking speed in children with cerebral palsy.

The number of individuals to be included in the study has been determined using G\*Power 3.1.9.7 effect size: 0.80, α = 0.05, power: 0.95. Individuals with CP who attend specific rehabilitation centres in Gaziantep and Kahramanmaraş and have GMFCS levels 1 and 2 will be included in the study. The necessary permissions will be obtained from the centres. The demographic information, clinical levels, and clinical types of the individuals will be recorded using a form. The Postural Control Measurement in Sitting, Paediatric Berg Balance Test, and Functional Reach Test will be used to assess the postural control of children with SP. Walking speed will be assessed using the Timed Up and Go Test. In our study, a lordosis angle will be created to support the existing lordosis using a steel-baleen elastic soft lumbosacral orthosis, and its effect on performance will be investigated using the tests applied. A soft lumbosacral orthosis suitable for the individuals will be used in three dimensions. Half of the individuals will be evaluated using these test methods first with a corset and then without a corset; the other half will be evaluated first without a corset and then with a corset. Tests will be repeated before and after orthosis use to determine the effectiveness of the orthosis.
