Immediate Effect of Soft Lumbosacral Orthosis on Trunk Stability and Upper-Limb Functionality in Children with Cerebral Palsy

ABSTRACT Introduction Lumbar lordosis is important for the spine and pelvis to work in harmony in providing trunk control and maintaining sagittal balance. Children with cerebral palsy (CP) have difficulties in providing trunk postural control and balance, which is critical for independence in daily living activities. This study was planned to examine the immediate effect of a lower-trunk orthosis supporting physiological lumbar lordosis on trunk control and upper-limb functionality in children with CP. Objectives and Methods A total of 30 children with CP, 13 diparetic, 11 hemiparetic, and 6 ataxic, 21 ambulatory (GMFCS I/II), and 9 nonambulatory (GMFCS III/IV) aged 3–16 years were included in the study. The Pediatric Functional Reach Test (PFRT) and the Seated Postural Control Measure (SPCM) were used to assess trunk control; the Pediatric Berg Balance Scale (PBBS) was used to assess balance; and the Box and Block Test (BBT) and the Nine-Hole Peg Test (9HPT) were used to evaluate upper-limb functions. All tests were performed with and without a soft lumbosacral brace. The braces were made of soft, elastic fabric with steel, and were made by the orthotic technician in four different sizes. The angle of lordosis was adjusted with steel underwires according to each child. The existing physiological lordosis of the child is supported by the brace. It is not intended to increase or decrease. Results In the study, the results of all evaluations with a brace were better than those without a brace ( P < 0.05). No significant difference was found only in the functional part of the SPCM test ( P > 0.05). Conclusions Our study revealed that soft lumbosacral orthosis, which supports physiological lordosis, has a positive effect on trunk stability and upper-limb functionality in children with CP. Clinical Relevance In children’s trunk stability and upper-limb functionality studies, the use of soft lumbosacral orthosis that supports physiological lordosis can be added to rehabilitation programs and daily living activities as a support.
