Palliative single-level selective dorsal rhizotomy for children with spastic cerebral palsy Gross Motor Function Classification System level IV and V: a case series and systematic review of the literature.

Single-level selective dorsal rhizotomy (SDR), typically indicated for ambulatory patients, is a controversial topic for severe spastic cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level IV or V. The objective of this case series and systematic literature review was to outline the indication and outcome of palliative SDR for nonambulatory patients with CP and GMFCS level IV and V, focusing on improvement of spasticity and of patient and caregiver reported quality of life assessment. A retrospective case series of patients with CP and GMFCS level IV or V who underwent single-level SDR at the authors' institution is presented. Furthermore, two databases (PubMed and Embase) were searched and a systematic review with a search string based on the terms "selective dorsal rhizotomy," "cerebral palsy," and "outcome" was conducted. The primary outcome was the reduction of spasticity based on the modified Ashworth scale (MAS). Secondary outcomes were change on the Gross Motor Function Measure-66 (GMFM-66), evaluation of patient-reported outcome measures (PROMs), surgical morbidity, and mortality. Eleven consecutive children under the age of 25 years undergoing palliative single-level SDR were included. All patients showed a reduction in MAS score (mean 1.09 ± 0.66 points) and no surgical morbidity and mortality occurred. For the systematic review results from our case series, in addition to 4 reports, 274 total patients were included. Reduction of spasticity based on MAS score was noted in all studies (mean range 1.09-3.2 points). Furthermore, in 2 studies spasticity of the upper extremities showed a MAS score reduction as well (range 1.7-2.8 points). The GMFM-66 score improved in 72% of the patients, while bladder function improved in 78% of the patients. Based on the PROMs, 92% of the patients/caregivers were satisfied with the outcome and their quality of life after the procedure. Two wound infections (2.7%) and one CSF leak (1.3%) occurred, while no surgery-related deaths were described. This analysis showed an improvement in spasticity, daily care, and comfort for patients with CP and GMFCS levels IV and V. Larger cohorts analyzing the outcome of palliative single-level SDR, based on the MAS, GMFM-66, and PROMs, are still needed and should be the focus of future studies.

Supported Standing and Supported Stepping Devices for Children with Non-Ambulant Cerebral Palsy: An Interdependence and F-Words Focus.

Children functioning at Gross Motor Function Classification System (GMFCS) levels IV-V cannot maintain an aligned standing position or take steps without support. Upright positioning and mobility devices have psycho-social significance for these children and their families, enhancing use of vision, communication, functioning and emotional well-being. Standers and supported stepping devices facilitate opportunities for biomechanical loading, potentially helping to build and maintain muscle and bone integrity, and they promote physical development. However, families are often required to choose between these two devices for their young child. This study aims to synthesize evidence for use and benefits of both supported standing and stepping devices through the lens of two contemporary theoretical frameworks to support clinical reasoning and implementation. The F-words for childhood development (functioning, family, fitness, fun, friends, future) and the interdependence-Human Activity Assistive Technology (iHAAT) models were combined to illustrate the complex interactions between the child, family, caregivers, peers and contextual factors when implementing standing and stepping devices with children at GMFCS levels IV and V. Supported standing and stepping devices provide complementary benefits, and both may be necessary starting at 9-15 months. We propose they both be included ON-Time, along with other age-appropriate positioning and mobility devices, to promote more equitable developmental opportunities for children with non-ambulant cerebral palsy.

Knee and ankle range of motion and spasticity from childhood into adulthood: a longitudinal cohort study of 3,223 individuals with cerebral palsy.

Reduced range of motion (ROM) and spasticity are common secondary findings in cerebral palsy (CP) affecting gait, positioning, and everyday functioning. These impairments can change over time and lead to various needs for intervention. The aim of this study was to analyze the development path of the changes in hamstring length, knee extension, ankle dorsiflexion, and spasticity in hamstrings and gastrosoleus from childhood into adulthood in individuals with CP at the Gross Motor Function Classification System (GMFCS) levels I-V. A longitudinal cohort study was undertaken of 61,800 measurements in 3,223 individuals with CP, born 1990-2017 and followed for an average of 8.7 years (range 0-26). The age at examination varied between 0 and 30 years. The GMFCS levels I-V, goniometric measurements, and the modified Ashworth scale (MAS) were used for repeated assessments of motor function, ROM, and spasticity. Throughout the follow-up period, knee extension and hamstring length exhibited a consistent decline across all individuals, with more pronounced decreases evident in those classified at GMFCS levels III-V. Ankle dorsiflexion demonstrated a gradual reduction from 15° to 5° (GMFCS I-IV) or 10° (GMFCS V). Spasticity levels in the hamstrings and gastrosoleus peaked between ages 5 and 7, showing a propensity to increase with higher GMFCS levels. Passive ROM continues to decrease to 30 years of age, most pronouncedly for knee extension. Conversely, spasticity reached its peak at a younger age, with a more notable occurrence observed in the gastrosoleus compared with the hamstrings. Less than 50% of individuals had spasticity corresponding to MAS 2-4 at any age.

Prevalence and Treatment of Surgical Complications Following Proximal Femoral Osteotomies in Children with Cerebral Palsy: An Analysis of 1085 Hips.

Proximal femoral osteotomy (PFO) is a reconstructive surgical option used to improve hip containment or correct internal hip rotation gait in children with cerebral palsy (CP). A few reports describe the risk of surgical complications after PFO. The purpose of this study was to determine the risk factors associated with adverse postoperative surgical outcomes in pediatric patients with CP following PFO and to report the treatment of complications. Following institutional review board approval, 1085 (1003 primary and 82 secondary) PFO procedures were retrospectively reviewed in 563 children with CP with at least 1year of follow-up after final surgery over an 18-year follow-up period. Demographic characteristics, motor type, gross motor function classification system (GMFCS) level, medical comorbidities, feeding tube status, seizure history, intervention type, and prevalence of PFO-related surgical complications and associated treatments were evaluated. Multivariate regression analysis was performed to determine risk factors for all surgical complications. During a 5.8-year (± 3.8years) follow-up, at least 1 surgical complication was identified in 143 (13.1%) hips in 121 (21.5%) patients after PFO in children with CP. Of these complications, the most common was heterotopic ossification (65 [6%] of hips); most of which were asymptomatic and required no treatment. Other complications included 25 (2%) nonunions, 21 (2%) deep or superficial infections, 13 (1%) delayed unions, 12 (1%) peri-implant fractures, and 7 early implant failures (0.64). The rate of revision surgery due to these complications was 13.1% (6.8% of hips), of which 41% (30 revision surgeries) were for the treatment of nonunion. Regarding the development of delayed union or nonunion, dystonia, GMFCS level IV/V, and seizure history were identified as risk factors by multivariate analysis. The prevalence of surgical complications after PFO was 13.1% with 6.8% of hips requiring revision surgery. Dystonia, seizure history, and nonambulatory status were the strongest predictors for the need for revision surgery after PFO. These data can be used to help counsel patients and families regarding the risks associated with PFO for children with CP.Level of proof: IV; retrospective study.

Baby Observational Selective Control AppRaisal (BabyOSCAR): Scores at 3 months predict functional ability, spastic cerebral palsy distribution, and diagnosis at 2 years.

To assess the predictive capabilities of the Baby Observational Selective Control AppRaisal (BabyOSCAR) tool, administered at 3 months corrected age, in determining spastic cerebral palsy (CP) outcome, functional abilities, and body topography at 2 years of age or later. Independent joint motions were measured at age 10 to 16 weeks from video recordings of spontaneous movement using BabyOSCAR in a sample of 75 infants. All included infants had known 2-year outcomes (45 with spastic CP and 30 without CP) including Gross Motor Functional Classification System (GMFCS) levels and CP body distribution. Receiver operating characteristic curves and cut points indicating greatest sensitivity and specificity were generated for predictive performance. Total BabyOSCAR score was a strong predictor of future outcome of spastic CP (cut score of 22.5, sensitivity = 98%, specificity = 100%, area under the curve = 0.99), and was able to distinguish children classified in GMFCS levels I and II from those in III to V (cut score of 13.5, sensitivity = 92%, specificity = 89%, area under the curve = 0.94). Having an (absolute) asymmetry score on the BabyOSCAR of more than 5 was a predictor of having unilateral CP at age 2 years (sensitivity = 56%, specificity = 100%, area under the curve = 0.86). BabyOSCAR scores are predictors of diagnosis, body distribution, and future gross motor function in infants with spastic CP at 2 years of age or later. Decreased independent joint movement at 3 months predicts spastic cerebral palsy (CP) at 2 years. Baby Observational Selective Control AppRaisal (BabyOSCAR) scores ≤13 are predictive of Gross Motor Function Classification System (GMFCS) levels III to V. BabyOSCAR scores of 14 to 22 are predictive of GMFCS levels I and II. A BabyOSCAR total asymmetry score >5 predicts unilateral CP. Stereotyped movements are more prominent in those who will be diagnosed with spastic CP at 2 years.

Pediatric Outcomes Data Collection Instrument Scores Within Gross Motor Function Classification Scale Levels and Functional Mobility Scale Ratings in Individuals With Cerebral Palsy.

The Pediatric Outcomes Data Collection Instrument (PODCI) is a patient/parent-reported outcome measure used in children with cerebral palsy (CP). PODCI score variability has not been widely examined in patients of Gross Motor Function Classification System (GMFCS) level IV or using the Functional Mobility Scale (FMS). The purpose of this study is to examine the distribution of PODCI scores within patients with CP GMFCS levels I-IV and FMS levels 1-6. Retrospectively identified patients with CP whose parent/caregiver had completed the PODCI at their visit were grouped based on GMFCS and FMS level. One-way ANOVA with pairwise Bonferroni-adjusted post hoc tests was performed to compare the effect of GMFCS and FMS levels (1, 2-4, 5, or 6) on PODCI scores. Three hundred sixty-seven patients were included (128 female, 11.7 years, SD 3.6). Global, Sports, Transfer, and Upper Extremity scores differed among all GMFCS levels ( P ≤0.056) and were significantly lower for GMFCS IV compared with all other levels. Happiness, Expectations, and Pain scores did not differ significantly among GMFCS levels including level IV ( P >0.06). Similar trends were seen at all FMS distances (5, 50, and 500âm). At 50âm, Global, Sports, Transfer, and Upper Extremity scores differed significantly among all FMS levels ( P <0.001) except that Upper Extremity Scores were similar between levels 2-4 and level 5 ( P =1.00). Happiness and Pain scores were not different between FMS levels ( P >0.27). Expectations scores differed only between FMS 1 and FMS 6 with FMS 6 being higher at the 50-m distance only ( P =0.03). Parent-reported outcome measures are important for providing patient-centered care. Providers can examine these measures alongside functional classification systems to create a more complete clinical picture of the patient. Providers should be aware of the score trends seen in our results when evaluating the PODCI for individuals with CP to improve shared decision-making and better monitor their need for future care. Level III-retrospective study.

Reconsidering the Gold Standard for the Assessment of Spastic Equinus Foot.

To determine whether differences exist in the measured range of motion (ROM) by the goniometer, equinometer, and 3-dimensional (3D) gait analysis in different settings (under general anesthesia (GA) or in the clinic) among patients with cerebral palsy. A prospective comparative cohort study was conducted at our orthopaedics center, where 15 patients with diplegic cerebral palsy (30 limbs) were evaluated, all of whom had Gross Motor Function Classification System (GMFCS) level I and II. ROM was measured by (1) goniometer under GA (benchmark), (2) goniometer analysis during clinical examination, (3) equinometer under GA, (4) equinometer in the clinic, and (5) 3D gait analysis. ROM was measured during both knee flexion and extension. Subgroup analysis based on the GMFCS level was performed. Nine patients were male with GMFCS level I and a mean age of 14.3 (SD=7.2) years. Statistically significant differences were noted between all studied measurement techniques in terms of ROM, dorsiflexion, and plantarflexion during both knee flexion and extension. The GMFCS level was an effect modifier of ROM measurements. The ROM parameters during both knee flexion and extension differed from one measurement device/technique to another. The GMFCS level played a notable effect-modifying role on the ROM parameters.

More dietary advice may be needed to support healthy body composition for children with cerebral palsy in Aotearoa New Zealand

The available literature on the nutritional status of children with cerebral palsy (CP) worldwide has identified high rates of malnutrition, specifically undernutrition(1). However, there is a current lack of clear CP-specific dietary guidelines for children with CP across all functional levels. Standard reference tools such as estimated energy requirement (EER) and recommended dietary intake (RDI) may overestimate requirements in children with CP, especially those with reduced mobility and activity levels. Furthermore, for children with severe CP, body composition data indicates higher risks of obesity and obesity-related conditions(2). There can be a wide range of functional abilities, classifiable with tools such as the Gross Motor Function Classification System (GMFCS) and the Eating and Drinking Ability Classification System (EDACS). The majority of nutrition-related CP literature focuses on children requiring assistance for feeding (EDACS IV-V) with little information available for children with higher levels of functional independence. The aim of this study was to determine whether children with CP had received any prior dietary guidance for healthy body composition and to summarise the type of advice received. Children aged 5-12 years and their whānau were invited to participate in a study where a purpose-developed questionnaire captured their history of receiving tailored dietary recommendations for CP. Body composition was assessed via whole-body dual-energy X-ray absorptiometry scan. Nine participants (6 males, median age: 10y, n = 2 Māori), across GMFCS levels I-IV and EDACS levels I-III took part in the study. Out of 9 children, 5 (55%) indicated that their child had never received dietary advice, 3 of whom were classified as obese or overweight based on growth chart percentiles using their measures of body fat percentage, 1 was classified as underweight and 1 was within the healthy ranges. Of the 4 who had previously received advice, its nature was reported as in support of weight gain (n = 3), and weight loss (n = 1). All 4 received dietary advice from a dietitian and 1 reported some additional advice from a pediatrician and/or orthopedic doctor. Two of the children who had received dietary advice fell within a healthy body fat percentage based on the growth chart percentiles at the time of the study, while the other two were classified as overweight or obese. The results indicate the importance of developing clear dietary guidance for children with CP which may differ from that for typically developing children, particularly depending upon CP subtype diagnosis and functional level, in order to support healthy body composition.

Corrective Efficacy of Calcaneal Lengthening Osteotomy for Planovalgus Deformity in Cerebral Palsy Patients.

Introduction Planovalgus deformity is common in children with spastic cerebral palsy (CP), particularly spastic diplegia and spastic quadriplegia. It results from muscle imbalance over the immature foot skeleton, leading to hindfoot valgus, forefoot abduction, and joint subluxation. Surgical interventions, like calcaneal lengthening osteotomy (CLO), are frequently employed to correct this deformity, but objective guidelines for its use in CP patients are lacking. Material and methods This retrospective cohort study examined the efficacy of CLO in correcting plano valgus deformity in pediatric CP patients at the Pediatric Orthopedic Unit of Christian Medical College (CMC) in Vellore, India. Data from patient records and radiographs were collected, including demographics, pre- and postoperative angles, and surgical details. Statistical analysis was performed to assess changes in angles and associations with various factors. Results After the surgery, there was a notable enhancement in the calcaneal pitch, lateral talo-first metatarsal angle, and naviculocuboid overlap, as shown by the CLO results. However, tibiocalcaneal angles did not show significant changes. Associations were observed between age, Gross Motor Function Classification System (GMFCS) level, additional surgeries, and postoperative angle corrections. Conclusion CLO shows promise in correcting plano valgus deformity, with age, GMFCS level, and comorbidities influencing outcomes. Long-term follow-up is crucial to monitor correction durability. Specific radiographic angles provide insights into CLO's biomechanical effects, but study limitations warrant caution in interpretation. CLO effectively corrects plano valgus deformity in pediatric CP patients, with age, GMFCS level, and comorbidities influencing outcomes. Long-term follow-up and further research are needed to optimize management strategies and enhance understanding of surgical outcomes.

Prevalence of Sensory Processing Deficits in Children with Spastic Cerebral Palsy - An Indian Caregiver's Perspective.

This study aims to analyze the prevalence and patterns of sensory processing deficits (SPD) in Indian children with spastic cerebral palsy (CP) using child sensory profile-2 (CSP-2) caregiver questionnaire. The authors surveyed 230 caregivers of children aged 3 to 14 y with spastic CP, using CSP-2. The difference in prevalence and distribution of SPDs among the CP subtypes and Gross Motor Function Classification System (GMFCS) levels was done. Overall prevalence of "Definite" (>2 SD) SPDs was 83%. Forty-seven percent had definite SPDs in more than one sensory subsection. Prevalence of definite SPDs was similar among the spastic CP subtypes. "Conduct" domain had more affection among hemiplegics and quadriplegics. "Avoiding" pattern was observed more in quadriplegics and "Seeking" pattern was observed less in diplegics. Severe GMFCS levels had more definite sensory processing deficits. SPDs are highly prevalent in children with spastic CP with unique patterns of affection among the spastic CP subtypes.

Does Size Really Matter? Incidence of Periprosthetic Fractures After Femoral Osteotomy in Patients With Cerebral Palsy.

Of children, 30% to 35% with cerebral palsy (CP) develop hip subluxation or dislocation and often require reconstructive hip surgery, including varus derotation osteotomy (VDRO). A recent literature review identified postoperative fractures as the most common complication (9.4%) of VDROs. This study aimed to assess risk factors for periprosthetic fracture after VDRO in children with CP. A total of 347 patients (644 hips, 526 bilateral hips) with CP and hip subluxation or dislocation (129 females; mean age at index VDRO: 8.6 y, SD 3.4, range: 1.5 to 17.7; 2 Gross Motor Function Classification System (GMFCS) I, 35 GMFCS II, 39 GMFCS III, 119 GMFCS IV, 133 GMFCS V, 21 unavailable) were included in this retrospective, single-group intervention (VDRO) study at a tertiary referral center. Imaging and clinical documentation for patients age 18 years or younger at index surgery, treated with VDRO were reviewed to determine demographic data, GMFCS level, surgeon, type of hardware implanted, use of anticonvulsants and steroids, type of postoperative immobilization, presence of periprosthetic fractures, fracture location and mechanism, and time from surgery to fracture. Potential determinants of periprosthetic fractures were assessed using mixed effects logistic regression. Of 644 hips, 14 (2.2%, 95% CI: 1.3%, 3.6%) sustained a periprosthetic fracture, at a median of 2.1 years postoperatively (interquartile range: 4.6 y, range: 1.2 mo to 7.8 y). Patients with a fracture had a median age at index surgery of 7.3 years (interquartile range: 4.3, range: 2.8 to 17.8; 1 GMFCS II, 6 GMFCS IV, 7 GMFCS V). Periprosthetic fractures were not significantly related to age at index surgery ( P = 0.18), sex ( P = 0.30), body mass index percentile ( P = 0.87), surgery side ( P = 0.16), anticonvulsant use ( P = 0.35), type of postoperative immobilization ( P = 0.40), GMFCS level ( P = 0.31), or blade plate size ( P = 0.17). Only surgeon volume significantly related to periprosthetic fracture (odds ratio = 5.03, 95% CI: 1.53, 16.56, P = 0.008), with the highest-volume surgeon also using smaller blade plates ( P < 0.01). Periprosthetic fractures after VDRO surgery in children with CP are uncommon, and routine hardware removal appears unnecessary. The data suggest that the common dogma of putting in the largest blade plate possible to maximize fixation may increase the risk of periprosthetic fracture. Due to the overall low fracture rate, especially when contextualized relative to the risk of hardware removal, a reactive approach to hardware removal appears warranted. Level III-retrospective study (targeting varus derotational osteotomies in children with cerebral palsy).

Incidence and sequence of scoliosis and windswept hip deformity: which comes first in 4148 children with cerebral palsy? A longitudinal cohort study

BackgroundThe aim was to analyse whether scoliosis or windswept hip deformity (WSH) occurs first for children with cerebral palsy (CP).MethodsThis longitudinal cohort study using data from 1994 − 2020 (26 years) involved 41,600 measurements of 4148 children (2419 [58.3%] boys) with CP born 1990 − 2018 and registered into the Swedish CP follow-up program. Children were followed from a mean age of 2.8 [SD 1.4] years, until they developed either scoliosis or WSH or were removed at surgery.ResultsWSH developed first in 16.6% of the children (mean age 8.1 [SD 5.0] years), and scoliosis in 8.1% (mean age 8.1 [SD 4.9] years). The incidence of WSH was higher than scoliosis across all levels I–V of the Gross Motor Function Classification System (GMFCS), both sexes, and for those with dyskinetic (20.0%) or spastic (17.0%) CP. The incidence of scoliosis was highest (19.8%) and developed earliest in children with GMFCS level V (mean age 5.5 [SD 3.5] years), and in children with dyskinetic (17.9%) CP (mean age 7.0 [SD 4.7] years).ConclusionsWSH presents earlier than scoliosis in most children with CP. Children with higher GMFCS level or dyskinetic CP are more likely to develop these deformities at a younger age.

Relationship of Gross Motor Function Classification System Level with The Incidence of Epilepsy

Epilepsy is one of the comorbidities or complications that can occur in cerebral palsy (CP) pediatric, the severity of CP can be measured using the gross motor function classification system (GMFCS) level. The aim of this study was to determine the relationship of GMFCS level with incidence of epilepsy in CP pediatric at RSUD Ulin Banjarmasin. This research used a cross – sectional method. Subjects were CP pediatric outpatients aged 2-18 years at pediatric polyclinic and medical rehabilitation installation RSUD Ulin Banjarmasin. Samples were obtained with total sampling technique during September-November 2021. Data were analyzed univariate and bivariate by Fisher’s exact test with a significance level of p &lt;0,005. There were 33 CP pediatric who fulfilled the inclusion and exclusion criteria. The result showed that most of the patients were aged 2-5 years (63,6%), male sex (57,6%), severe GMFCS levels (75,8%) and had epilepsy (66,7%). There was a significant correlation of GMFCS level with incidence epilepsy (p=0,008, PR=3,2). It can be concluded that GMFCS level is associated with incidence epilepsy in CP pediatric at RSUD Ulin Banjarmasin.

Increased Upper Extremity Muscle Mass in Ambulatory Children with Cerebral Palsy.

To compare muscle mass in the upper and lower extremities between ambulatory children with cerebral palsy (CP) and typically developing (TD) children. A total of 21 children aged 2 to 12 years with CP and a Gross Motor Function Classification System (GMFCS) level of I, II, or III were matched with 21 TD children for age, sex, and body mass index. The lean body mass (LBM) of each extremity was calculated from whole-body dual-energy X-ray absorptiometry. The LBM of the upper extremities was greater in children with CP compared to TD children, and the difference was significant in the GMFCS level II group (1340.6 g vs. 1004.2 g, p = 0.027). There was no significant difference in the LBM of the lower extremities between the CP and TD groups (p = 0.190). The ratio of lower extremity LBM to total extremity LBM was lower in children with CP, while the ratio of upper extremity LBM to total extremity LBM was higher in children with CP (73.2% vs. 78.5% [p < 0.001] and 26.7% vs. 21.5% [p < 0.001], respectively). Ambulatory children with CP, especially in the GMFCS level II group, exhibit greater muscle mass in the upper extremities compared to TD children.

Quality of Movement Changes in Ambulatory Children with Cerebral Palsy 1 Year after Selective Dorsal Rhizotomy

Background: Quality of movement is an important component of effective gross motor performance in children with cerebral palsy. This study used the Quality Function Measure (QFM) to evaluate changes in quality of movement in ambulatory children with cerebral palsy 1 year after selective dorsal rhizotomy (SDR). Methods: In a retrospective study, using a single-group repeated measure design, 48 children (28 male) at preoperative Gross Motor Function Classification System (GMFCS) level II ( n = 18) and III ( n = 30) were evaluated. Mean (standard deviation) age at surgery was 7 years 11 months (2 years 3 months). Scores for all five QFM attributes, Alignment, Coordination, Dissociated Movements, Stability and Weight-shift were obtained. Results: All QFM attributes improved significantly ( p &lt; 0.001) for all children and within both GMFCS levels. Mean (SD) change in QFM scores varied from 9.02% (8.61) for Stability to 26.5% (22.06) for Alignment. Conclusion: SDR and subsequent rehabilitation are associated with an improvement in the quality of gross motor movement in children with cerebral palsy. This study provides clinicians and families with further evidence supporting the value of SDR in this population. Further studies need to evaluate the impact of improved quality of movement on a child's function and participation in the real world.

Use of primary health care services among children and adolescents with cerebral palsy.

To investigate the use of general practitioners and urgent care centres (UCC) among children and adolescents with cerebral palsy (CP) compared to a control group, and per gross motor function level. Data on children with CP born 1996 to 2014 were collected from the Norwegian Quality and Surveillance Registry for Cerebral Palsy. A control group was extracted from Statistics Norway. The date and diagnosis codes for general practitioner and UCC contacts from 2006 to 2015 were collected from the Norwegian Control and Payment of Health Reimbursement Database. Incidence rate ratios (IRR) for the number of contacts per person-year with 95% confidence intervals (CI) were calculated using Poisson regression. Risk differences with 95% CI were used to compare cumulative diagnosis incidences between children with CP and the control group. The study included 2510 children (1457 males; 58.1%) with CP and 12 041 (7003 males; 58.2%) without CP (mean age in both groups 7 years 2 months, SD 4 years 8 months, range 0-19 years), with 336 250 contacts. Children with CP had more general practitioner (IRR 1.47; 95% CI 1.29-1.67) and UCC (IRR 1.30; 95% CI 1.13-1.50) contacts than children without CP, for all ages. IRRs remained unchanged when comparing children with CP in Gross Motor Function Classification System (GMFCS) levels I and II to children without CP. Among children with CP, contact increased as GMFCS levels increased, and they were in contact most often for respiratory and general and unspecified diagnoses. The risk for epilepsy was highest for those in contact with general practitioners. Children with CP, including those with less severe motor impairments, contacted general practitioners and UCCs more than children without CP. However, contact increased as gross motor impairment increased. They had contact for many diagnoses, mostly respiratory.

Pelvic Tilt in Adults With Cerebral Palsy and Its Relationship With Prior Hamstrings Lengthening.

Current studies assessing the change in pelvic tilt for ambulatory patients with cerebral palsy (CP) after surgical hamstring lengthening (SHL) lack a comparison cohort without prior SHL and are limited to younger patients. This study presents gait data of middle-aged adults with CP, primarily focusing on the pelvis, and compares pelvic tilt, trunk tilt, and knee flexion between those with and without prior SHL. A consecutive series of 54 adults with CP, a mean age of 36±13 years, and Gross Motor Function Classification System (GMFCS) levels I-III were included. Thirty-two (59%) had SHL performed at a mean age of 8±5 years. Three-dimensional gait analysis data prospectively collected at a mean of 28±14 years postoperatively were retrospectively analyzed. Chi-square tests were used to compare demographic and surgical history data and statistical parameter mapping was used to compare knee flexion during stance and pelvic and trunk tilts during the gait cycle between SHL and SHL-naive groups. Age, GMFCS level, sex, race, topography, and ethnicity were not different between the groups (P=.217-.612). Anterior pelvic tilt throughout gait was significantly greater in the SHL group compared with the SHL-naive group (63%-87%; P=.033). This difference was augmented after accounting for other surgical history and revision SHL (0%-32%, P=.019; and 46%-93%, P=.007). Within a cohort of adults with CP, GMFCS levels I-III, and a mean age of 36 years, those with a history of SHL, performed a mean of 28 years prior to 3-dimensional gait analysis, walked with increased anterior pelvic tilt compared with those without a history of SHL. [Orthopedics. 2024;47(5):270-275.].

Correlation of Siting and Standing Performance with Gross Motor Functional Classification System in Children with Spastic Cerebral Palsy

Background: Cerebral palsy (CP) is the most common motor disability in childhood, with spasticity as a frequent complication. Understanding the relationship between the Gross Motor Function Classification System (GMFCS) and motor abilities, such as sitting and standing performance, is critical for managing CP. Objective: This study aimed to analyze the correlation between sitting and standing performance with GMFCS in children with spastic cerebral palsy. Methods: A cross-sectional study was conducted with 350 children diagnosed with CP, aged 6-12 years. Data were gathered over six months at a government secondary school for special education. The GMFCS was used to classify motor function, while sitting and standing abilities were assessed using the Sit to Stand Test. Data analysis was performed using SPSS version 25, employing descriptive statistics and Spearman's rank correlation. Results: The study found that children at GMFCS levels I and II could often sit and walk with minimal or no assistance, whereas those at levels IV and V exhibited varied sitting abilities and primarily used technological aids or wheelchairs. A statistically significant association between sitting ability and GMFCS level was identified (Pearson Chi-Square = 29.151, p = 0.023). Children with spastic CP were predominantly classified at GMFCS levels III (49 participants) and V (49 participants), while those with dyskinetic CP were mainly at level II (13 participants). Conclusion: The GMFCS is an effective tool for assessing gross motor function in children with CP, with strong correlations found between GMFCS levels and sitting and standing performance. These findings can inform targeted interventions to improve mobility and quality of life for children with CP.

Go Zika Go: feasibility study with modified motorized ride-on cars for the mobility of children with Congenital Zika Syndrome (CZS)

Purpose To explore the feasibility of an intervention using modified ride-on cars in terms of acceptability and potential changes in goal attainment, mobility, social function, and participation of children with Congenital Zika Syndrome (CZS). Materials and Methods A pre- and post-intervention feasibility study was conducted with children with CZS, levels IV and V of the Gross Motor Function Classification System (GMFCS). The intervention consisted of 12 weeks of training (3 times a week for 40 min per session) and 4 weeks of follow-up. The primary outcomes included adherence, satisfaction, and learning in mobility. Secondary outcomes encompassed goal attainment, mobility, social/cognitive function, and participation. Descriptive statistics were performed. To explore potential individual changes with the intervention, Wilcoxon test was used to analyze Pediatric Evaluation of Disability Inventory – Computer Adaptive Test (PEDI-CAT) data and Young Children’s Participation and Environment Measure (YC-PEM)/Participation and Environment Measure for Children and Youth (PEM-CY), along with standard error measurements of the PEDI-CAT domains Results Four children participated (median age 4.75 years; two females: three at level V on the GMFCS). Adherence was 75% of the total intervention time, and family members reported being satisfied or very satisfied. Children showed gains in learning the use of the modified ride-on cars and an increase in goal attainment after the intervention. Individual changes were observed in the PEDI-CAT domains (mobility and social/cognitive), but there were no significant changes in participation outcomes. Conclusions Children with CZS at GMFCS levels IV and V can learn to use motorized ride-on cars, attainment goals, and experience satisfaction.

Recreational screen time behaviour among ambulatory children and adolescents diagnosed with cerebral palsy: A cross-sectional analysis.

To describe the recreational screen time behaviour of 8-16-year-olds diagnosed with cerebral palsy (CP) and explore associations between health-related quality of life, sleep duration and physical activity behaviour versus screen time. This cross-sectional study used proxy-reported questionnaire data of 381 ambulatory (with or without assistance) 8-16-year-olds diagnosed with CP corresponding to Gross Motor Function Classification System (GMFCS) levels I-III. Descriptive statistics were used to report age, sex and the GMFCS level. The potential associations of health-related quality of life, physical activity behaviour and sleep duration (dependent variables) versus screen time (independent variable) were determined using multiple linear regression. Health-related quality of life was evaluated using the Pediatric Quality of Life Inventory, including seven dimensions: Daily Activities; School Activities; Movement and Balance; Pain and Hurt; Fatigue; Eating Activities; and Speech and Communication. The participants spent a median screen time of 3.9h daily. The boys spent a longer screen time during weekends than the girls (p = 0.003). Boys spent more time on games (p < 0.001), whereas girls spent more time on social media and video calls (p < 0.001). Increasing age (p < 0.001) was associated with increased screen time but did not differ between the GMFCS levels. Sleep duration, perceived fatigue and perceived movement and balance correlated negatively with screen time. This study sheds light on the recreational screen time habits of ambulatory children and adolescents diagnosed with CP. Further investigation into the observed associations is warranted to investigate potential causation and relationships between sleep behaviour, quality of life and screen time behaviour.
