The Effect of Botulinum Toxin Injections on Gross Motor Function for Lower Limb Spasticity in Children with Cerebral Palsy
The aim of this study was to investigate the use of botulinum toxin type A (BoNT-A) injections and their efficacy on gross motor function for lower limb spasticity in children with spastic cerebral palsy (CP). This retrospective study included 919 injection occasions from 591 children with CP who received a lower limb BoNT-A injection between 2006 and 2016. The Gross Motor Function Measure (GMFM-88), the Modified Ashworth Scale, and the Modified Tardieu Scale were administered before and after injections. Injections were predominantly administered to children under the age of 6 years. The most common muscle injection site was the calf muscle for dynamic foot deformity. The second most commonly injected muscle was the hip adductor among 2-3 year olds and the hamstring muscle among 4-6 year olds. Distal injections were predominantly administered to high-functioning children, whereas proximal injections were typically administered to low-functioning children. Multilevel injections were mostly administered to midfunctioning children. GMFM-88 scores significantly increased post-injection for both high- and low-functioning groups. Younger age at injection and distal injection type were associated with larger improvements on the GMFM-88 at both short- and midterm follow-up. The target muscles for injection varied depending on gross motor functioning and age. Younger age at injection and distal injection type were significantly related with greater gain in gross motor function.ope
Change in Pulmonary Function after Incentive Spirometer Exercise in Children with Spastic Cerebral Palsy: A Randomized Controlled Study
PURPOSE: The aim of this study was to investigate the effect of incentive spirometer exercise (ISE) on pulmonary function and maximal phonation time (MPT) in children with spastic cerebral palsy (CP).
MATERIALS AND METHODS: Fifty children with CP were randomly assigned to two groups: the experimental group and the control group. Both groups underwent comprehensive rehabilitation therapy. The experimental group underwent additional ISE. The forced vital capacity (FVC), forced expiratory volume at one second (FEVβ), FEVβ/FVC ratio, peak expiratory flow (PEF), and MPT were assessed as outcome measures before and after 4 weeks of training.
RESULTS: There were significant improvements in FVC, FEVβ, PEF, and MPT in the experimental group, but not in the control group. In addition, the improvements in FVC, FEVβ, and MPT were significantly greater in the experimental group than in the control group.
CONCLUSION: The results of this randomized controlled study support the use of ISE for enhancing pulmonary function and breath control for speech production in children with CP.ope
Botulinum Toxin Type A Injection for Spastic Equinovarus Foot in Children with Spastic Cerebral Palsy: Effects on Gait and Foot Pressure Distribution
PURPOSE: To investigate the effect of intramuscular Botulinum toxin type A (BoNT-A) injection on gait and dynamic foot pressure distribution in children with spastic cerebral palsy (CP) with dynamic equinovarus foot.
MATERIALS AND METHODS: Twenty-five legs of 25 children with CP were investigated in this study. BoNT-A was injected into the gastrocnemius (GCM) and tibialis posterior (TP) muscles under the guidance of ultrasonography. The effects of the toxin were clinically assessed using the modified Ashworth scale (MAS) and modified Tardieu scale (MTS), and a computerized gait analysis and dynamic foot pressure measurements using the F-scan system were also performed before injection and at 1 and 4 months after injection.
RESULTS: Spasticity of the ankle plantar-flexor in both the MAS and MTS was significantly reduced at both 1 and 4 months after injection. On dynamic foot pressure measurements, the center of pressure index and coronal index, which represent the asymmetrical weight-bearing of the medial and lateral columns of the foot, significantly improved at both 1 and 4 months after injection. The dynamic foot pressure index, total contact area, contact length and hind foot contact width all increased at 1 month after injection, suggesting better heel contact. Ankle kinematic data were significantly improved at both 1 and 4 months after injection, and ankle power generation was significantly increased at 4 months after injection compared to baseline data.
CONCLUSION: Using a computerized gait analysis and foot scan, this study revealed significant benefits of BoNT-A injection into the GCM and TP muscles for dynamic equinovarus foot in children with spastic CP.ope
Neuropsychological Outcomes of Preterm Birth in Children With No Major Neurodevelopmental Impairments in Early Life
Objectives To investigate cognition, social adaptive functioning, behavior, and emotional development in the preschool period and to determine the effects of the age of onset of walking on those developmental areas in children who were born preterm without major neurodevelopmental impairments (NDI) early in life. Methods Fifty-eight children who were born preterm without major NDI early in life participated in this study. The Korean versions of the Wechsler Preschool and Primary Scale of Intelligence or the Bayley Scales of Infant Development, the social maturity scale, the Korean version of the Child Behavior Checklist (CBCL), Connersβ abbreviated parent/teacher rating scale, the Childhood Autism Rating Scale, and a speech developmental test were administered. The participants were divided into two groups: early walkers (group A) and late walkers (group B).Results The full-scale intelligence quotient (IQ) and performance IQ were significantly lower in group B than in group A, while the verbal IQ did not differ significantly between the groups. The children in group B had greater risks of cognitive deficits than did the children in group A, especially in performance skills. The social quotient (SQ) was significantly lower in group B than in group A (p<0.05). The rates of mild or significant deficits based on SQ and the CBCL did not differ significantly between the groups. Four children in group A and one child in group B had attention/hyperactivity problems. One child in group A had autistic behavior. Only one child in group B showed a significant speech developmental delay.Conclusions Problems in cognition, social adaptive functioning, and emotional and behavioral development can occur in children without major NDI early in life. Late walkers had significantly lower scores in cognition and social adaptive functioning than did early walkers.ope
Functional Communication Profiles in Children with Cerebral Palsy in Relation to Gross Motor Function and Manual and Intellectual Ability
PURPOSE: The aim of the present study was to investigate communication function using classification systems and its association with other functional profiles, including gross motor function, manual ability, intellectual functioning, and brain magnetic resonance imaging (MRI) characteristics in children with cerebral palsy (CP). MATERIALS AND METHODS: This study recruited 117 individuals with CP aged from 4 to 16 years. The Communication Function Classification System (CFCS), Viking Speech Scale (VSS), Speech Language Profile Groups (SLPG), Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and intellectual functioning were assessed in the children along with brain MRI categorization. RESULTS: Very strong relationships were noted among the VSS, CFCS, and SLPG, although these three communication systems provide complementary information, especially for children with mid-range communication impairment. These three communication classification systems were strongly related with the MACS, but moderately related with the GMFCS. Multiple logistic regression analysis indicated that manual ability and intellectual functioning were significantly related with VSS and CFCS function, whereas only intellectual functioning was significantly related with SLPG functioning in children with CP. Communication function in children with a periventricular white matter lesion (PVWL) varied widely. In the cases with a PVWL, poor functioning was more common on the SLPG, compared to the VSS and CFCS. CONCLUSION: Very strong relationships were noted among three communication classification systems that are closely related with intellectual ability. Compared to gross motor function, manual ability seemed more closely related with communication function in these children.ope
Case Report: Non-Val30Met TTR Type Familial Amyloid Polyneuropathy with Asp38Ala Mutation
There are three precursor proteins of amyloid inducing familial amyloid polyneuropathy (FAP): transthyretin (TTR),
Apolipoprotein A-1, and Gelsolin. Abnormal TTR expression is most frequently discovered in FAP and the genotypes
are correlated with clinical features. Since the substitution of methionine for valine at position 30 is most common gene
mutation, TTR type FAP is divided into Val30Met type FAP and non-Val30Met type FAP. Asp38Ala mutation found in
non-Val30Met type FAP usually accompanied the autonomic symptoms and only reported in male persons in Korea. We
reported the clinical characteristics and disease progression of first Korean female person with Asp38Ala mutation who
didnβt show autonomic symptoms.ope
Cerebral Palsy due to Intracranial Hemorrhage Caused by Consumptive Coagulopathy in Protein C Deficiency: A Case Report
Protein C (PROC) is a potent anticoagulant inactivating coagulation factors Va and VIIIa. PROC deficiency is very rare condition inherited as an autosomal dominant or recessive trait, and associated with various thromboembolic and ischemic conditions. Moreover, severe form of PROC deficiency can cause fatal hemorrhagic complications due to consumptive coagulopathy. We reported two children with hemorrhagic stroke who were diagnosed as severe PROC deficiency caused by two different types of compound heterozygous PROC gene mutations. We described results of laboratory tests, genetic analysis, brain magnetic resonance images, and functional outcomes. Both children received prophylactic anticoagulation therapy and presented with purple-colored skin lesions during rehabilitation. Purpura fulminans caused by insufficient anticoagulation should be differentiated from hematoma caused by excessive anticoagulation therapy in these children.ope
