The physeal injuries in children occur result of trauma, infection, metabolic or ischemic disease, and these conditions cause significant problems, such as growth disturbance, deformity and premature closure of physis. The authors experienced 7 cases of children who had angular deformity of knee and limb shortenings, but no history of obvious causes of physeal injury. All of these cases had severe osteoporosis and underlying disease, which were osteogenesis imperfecta, fibrous dyplasia and long term steroid therapy. The purpose of this study are evaluation of pathomechanism of physeal injuries in severe osteoporotic children. Patients were range of age from 4 to 9 years and had common clinical features, which were angular deformities of knee, limb shortening. Also they had common radiographic findings, that were severe porosis, metaphyseal sclerosis and in some cases, pop corn like calcification around physis. At this, we supposed that chronic mechanical stress in osteoporotic bone make physis be damaged due to loss of capillary circulation and this event appear to result from collapse of bone plate, through which epiphyseal vessel penetrate. In conclusion, the children with severe osteoporosis should be observed carefully about physeal injuries, which pathomechanism are perhaps deprivation of capillary circulation through bone plate. Therefore, We should try to protect bone plate by being conscious of its existence.

2.The Long-Term Outcome and Rehabilitative Approach of Intraventricular Hemorrhage at Preterm Birth
Journal of Korean Neurosurgical Society 2023;66(3):289-297
Technological advances in neonatology led to the improvement of the survival rate in preterm babies with very low birth weights. However, intraventricular hemorrhage (IVH) has been one of the major complications of prematurity. IVH is relevant to neurodevelopmental disorders, such as cerebral palsy, language and cognitive impairments, and neurosensory and psychiatric problems, especially when combined with brain parenchymal injuries. Additionally, severe IVH requiring shunt insertion is associated with a higher risk of adverse neurodevelopmental outcomes. Multidisciplinary and longitudinal rehabilitation should be provided for these children based on the patients’ life cycles. During the infantile period, it is essential to detect high-risk infants based on neuromotor examinations and provide early intervention as soon as possible. As babies grow up, close monitoring of language and cognitive development is needed. Moreover, providing continuous rehabilitation with task-specific and intensive repetitive training could improve functional outcomes in children with mild-to-moderate disabilities. After school age, maintaining the level of physical activity and managing complications are also needed.
3.Botulinum Toxin Type A Injection for Management of Upper Limb Spasticity in Children with Cerebral Palsy: a Literature Review.
Yonsei Medical Journal 2006;47(5):589-603
The aim of this article was to present a review of the research literature on the outcome of botulinum toxin type A (BTX-A) injection for management of upper limb spasticity in children with cerebral palsy (CP). We searched the electronic databases of MEDLINE, CINAHL and PUBMED for all published studies with full-length English text available. For each study, the quality of the methods and the strength of evidence were assessed by 2 independent reviewers based on the American Academy for Cerebral Palsy and Developmental Medicine (AACPDM) guidelines. Four studies of level I, 8 studies of level IV and 4 studies of level V were identified. Due to the limited number of studies with high quality evidence and inconsistent results among studies, we were unable to support or refute the usefulness of BTX-A injection for management of upper limb spasticity in children with CP. Moreover, we identified several variables that may affect the outcome of injection, such as timing of age, dosage, dilution volumes, localization techniques of target muscles and participant characteristics. In summary, we have presented a review the literature and a discussion of the considerable uncertainty and variation associated with the clinical use of BTX-A injection for management of upper limb spasticity in children with CP.

OBJECTIVE: To evaluate the effect of stretching therapy of neurogenic bladder in spinal cord injured patients. METHOD: Twelve spinal cord injured patients who had neurogeic bladder manifested with urinary incontinence resistant to oral and intravesical anticholinergic instillation treatment were selected. Oxybutynin solution was instillated via foley catheter and the catheter was clamped until incontinence occur. This was performed twice a day for 7 days. The urodynamic studies were compared before and after therapy. Total volume of daily incontinence and total volume of daily fluid intake were also monitored. RESULTS: After stretching therapy, median maximal bladder capacity increased from 190.08 to 457.17 ml (p<0.01), mean bladder compliance increased from 8.46 to 18.85 ml/cmH2O (p<0.01), mean reflex volume increased from 148.75 to 252.17 ml (p<0.05), mean maximal detrusor pressure decreased from 52.17 to 28.29 cmH2O (p<0.01), mean clinical maximal capacity increased from 277.50 to 537.50 ml (p<0.01), and mean daily incontinent volume decreased from 508.33 ml to 20.83 ml (p<0.01). No significant correlation was found between the duration since onset of injury and the urodynamic finding. CONCLUSION: This study proved that stretching therapy of bladder was an effective method in spinal cord injured patients who had neurogenic bladder with uncontrolled incontinence with conventional therapy.

PURPOSE: To identify the characteristics of static standing balance and its postural control mechanisms during quiet side-by-side standing and the changes in these measures whilst wearing hinged ankle-foot orthoses (AFOs) in children with bilateral spastic cerebral palsy (CP). MATERIALS AND METHODS: Twenty-one children with bilateral spastic CP (6.10 +/- 1.09 year-old) and 22 typically developing (TD) children (5.64 +/- 0.49 year-old) were recruited. Pressure data were recorded while subjects with or without AFOs stood on dual force platforms and net body center of pressure (CoP) coordinates were calculated from this data. Net body CoP was traced for measuring mediolateral (ML) and anteroposterior (AP) displacement and path length per second. Correlation coefficients between parameters representing ankle, hip, and transverse body rotation strategies were also analyzed. RESULTS: ML and AP displacement and path length per second of the CoP trajectory were higher in children with CP compared to TD children (p < 0.05). There were no significant improvements in these parameters whilst wearing hinged AFOs. Compared to TD children, children with CP used less ankle strategy though more hip and transverse rotation strategies for postural control during quiet standing. Whilst wearing hinged AFOs, the contribution of ankle strategy was significantly increased for ML balance control in children with CP (p < 0.05). CONCLUSION: Hinged AFOs for children with CP may be helpful in improving the postural control mechanisms but not the postural stability in quiet side-by-side standing.

The upper chest wall does not grow properly in children with spinal muscular atrophy (SMA) with paradoxical breathing. This suggests that long-term inability to take a deep breath in developing children may result in underdevelopment of the upper chest wall. In addition, a rapid and paradoxical breathing pattern is frequently observed in children with severe cerebral palsy (CP), which often corresponds to the underdevelopment of the upper chest wall. The present study is designed to evaluate the ratio of the upper to lower chest wall in children with severe spastic quadriplegic CP, compared with normal children. We compared normal children with children that had spastic quadriplegic CP who did not have kyphosis or scoliosis. Test subjects were matched in terms of age, height, and weight. The diameters of upper chest (D(apex)) and of lower chest (D(base)) were measured on the anteroposterior (AP) view of a chest X-ray and the D(apex) to D(base) ratio was calculated. In selected cases the forced vital capacity (FVC) was measured using a Wright Respirometer. The D(apex) to D(base) ratio was significantly lower in the CP group than in the control group (p < 0.001). The ratio increased linearly with age (p < 0.001) in both CP (R = 0.372) and control groups (R = 0.477). The FVC/preFVC showed significant correlation with the D(apex) to D(base) ratio (R = 0.542, p < 0.01). The results of this study suggest a deviation of optimal chest wall structure in children with spastic quadriplegic CP.

PURPOSE: This study used ultrasonography (US) to investigate the architectural changes in gastrocnemius muscles (GCM) after botulinum toxin injection (BoNT-A) in children with cerebral palsy (CP). MATERIALS AND METHODS: Thirteen children with CP who received a BoNT-A injection into their GCM to treat equinus were recruited (9 males and 4 females). Architectural changes in both the medial and lateral heads of the GCM from a total of 20 legs were assessed using B-mode, real-time US. Muscle thickness (MT), fascicle length (FL), and fascicle angle (FA) were measured over the middle of the muscle belly in both a resting and neutral ankle position. Measures at 1 and 3 months after the injection were compared with baseline data taken before the injection. RESULTS: The mean age of the subjects was 5.8 (+/-1.6) years. Spasticity was significantly reduced when measured by both the modified Tardieu scale and the modified Ashworth scale at 1 and 3 months after injection (p<0.05). The MT and FA of both the medial and lateral heads of the GCM were significantly reduced for both neutral and resting ankle positions at 1 and 3 months after the injection. The FL of both the medial and lateral heads of the GCM were significantly increased in a resting position (p<0.05), but not in a neutral position. CONCLUSION: Our results demonstrated muscle architectural changes induced by BoNT-A injection. The functional significances of these changes were discussed.

The purpose of this study was to evaluate how soft tissue surgery for correcting equinus deformity affects the kinematic and kinetic parameters of the ankle and proximal joints. Sixteen children with spastic hemiplegic cerebral palsy and equinus deformities (age range 3-16 years) were included. Soft tissue surgeries were performed exclusively on the ankle joint area in all subjects. Using computerized gait analysis (Vicon 370 Motion Analysis System), the kinematic and kinetic parameters during barefoot ambulation were collected preoperatively and postoperatively. In all 16 children, the abnormally increased ankle plantar flexion and pelvis anterior tilting on the sagittal plane were significantly improved without a weakening of push-off (p < 0.05). In a group of 8 subjects with a recurvatum knee gait pattern before operation, the postoperative kinematic and kinetic parameters of the knee joint were significantly improved (p < 0.05). In a group of 8 subjects with ipsilateral pelvic external rotation before operation, the postoperative pelvic deviations on the transverse plane were significantly decreased (p < 0.05). These findings suggest that the soft tissue surgery for correcting equinus deformity improves not only the abnormal gait pattern of the ankle, but also that of the knee and pelvis.

OBJECTIVE: To investigate the immediate effect of a single session of whole body vibration (WBV) on lower extremity spasticity in children with cerebral palsy (CP). METHODS: Seventeen children with spastic CP were included. A single session of WBV was administered: 10-minute WBV, 1-minute rest, and 10-minute WBV. The effects of WBV were clinically assessed with the Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) before and immediately, 30 minutes, 1 hour, 2 hours, 3 hours, and 4 hours after WBV. RESULTS: Spasticity of the ankle plantarflexor, as assessed by MAS and MTS scores, was reduced after WBV. Post-hoc analysis demonstrated that, compared to baseline, the MAS significantly improved for a period of 1 hour after WBV, and the R1 and R2–R1 of the MTS significantly improved for a period of 2 hours after WBV. CONCLUSION: A single session of WBV improves spasticity of ankle plantarflexors for 1–2 hours in children with CP. Future studies are needed to test whether WBV is an effective preparation before physiotherapy and occupational therapy.

PURPOSE: Hip adductor spasticity has a great impact on developing hip displacement in children with cerebral palsy (CP). Obturator nerve (ON) block is less invasive intervention rather than soft tissue surgery for reduction of hip adductor spasticity. The aim of this study is to investigate the effect of ON block on hip lateralization in low functioning children with spastic CP. MATERIALS AND METHODS: The study was performed by retrospective investigation of the clinical and radiographic follow-up data of low functioning children [gross motor function classification system (GMFCS) level III to V] with spastic cerebral palsy whose hip was subluxated. Migration percentage (MP) was measured on hip radiographs and its annual change was calculated. In intervention group, ON block was done with 50% ethyl alcohol under the guidance of electrical stimulation. RESULTS: The data of 49 legs of 25 children for intervention group and the data of 41 legs of 23 children for nonintervention group were collected. In intervention group, the MP were significantly reduced at 1st follow-up and the MPs at 2nd and last follow-up did not show significant differences from initial MP. Whereas in nonintervention group, the MPs at 1st, 2nd and last follow-up were all significantly increased compared to initial MPs. CONCLUSION: ON block with ethyl alcohol is useful as an early effective procedure against progressive hip displacement in these children with spastic CP.
