Management of Cerebrospinal Fluid Leak After Intrathecal Baclofen Pump Procedures in Adolescents With Cerebral Palsy: A Retrospective Study.

STUDY OBJECTIVE:  Epidural blood patches (EBPs) are frequently performed in children with cerebral palsy (CP) to manage post-dural puncture headache (PDPH) due to cerebrospinal fluid (CSF) leak after intrathecal baclofen pump (ITBP) placement or replacement procedures. The purpose of our study was to review the incidence and management of CSF leak following ITBP placement or replacement procedures in children with CP. The study was a retrospective review of 245 patients representing 310 surgical cases of baclofen pump insertion (n=141) or reinsertion (n=169) conducted at a 125-bed children's hospital with prominent specialty orthopedics surgical cases. MEASUREMENTS:  Demographic and clinical information was obtained from the anesthesia pain service database on all new ITBP placement and subsequent replacements over an eight-year period. MAIN RESULTS:  The overall incidence of CSF leak in our population was 16% (50 of 310) and 18% (25 of 141) with a new ITBP placement. Children with diplegia were associated with a threefold risk of developing CSF leak. Of patients who developed CSF leak (n=50), 68% (n=34) were successfully treated conservatively, while 32% (n=16) required EBPs. EBPs were successful in 87.5% (14 of 16) of patients at relieving PDPH on the first attempt.  Conclusions: CSF leak is a known problem after ITBP placement and replacement. Most patients were successfully treated with conservative management and EBPs were successful in patients failing conservative therapy. Diagnosing PDPH in non-verbal patients can be challenging.

Novel Machine Learning Analysis Algorithm of DNA Methylation Patterns Identifies Cerebral Palsy with Concurrent Epilepsy.

Background: Spastic cerebral palsy, the most common pediatric-onset disabling condition with an estimated prevalence of 0.2% in children, is a complex condition characterized by stiff movement, muscle contractures, and abnormal gait that can diminish quality of life. Spastic CP accounts for approximately 83% of all CP cases and frequently co-occurs with other complex conditions, like epilepsy. An estimated 42% of spastic CP cases have co-occurring epilepsy. Unfortunately, CP is often difficult to diagnose. Although most children with CP are born with it or acquire it immediately after birth, many are not identified until after 19 months of age with CP diagnosis often not confirmed until 5 years of age. New bioinformatic approaches to identify CP earlier are needed. Recent studies indicate that altered DNA methylation patterns associated with CP may have diagnostic value. The potential confounding effects of co-occurrent epilepsy on these patterns are not known. We evaluated machine learning classification of CP patients with or without co-occurring epilepsy. Results: Whole blood samples were collected from 30 study participants diagnosed with epilepsy (n=4), spastic CP (n=10), both (n=8), or neither (n=8). A novel Support-Vector-Machine learning algorithm was developed to identify methylation loci that have ability to classify CP from controls in the presence or absence of epilepsy. This algorithm was also employed to measure classification ability of identified methylation loci. After preprocessing of data, isolation of important methylation loci was performed in a binary comparison between CP and controls, as well as in a 4-way scheme, encapsulating epilepsy diagnoses. The classification ability was similarly assessed. CP Classification performance was evaluated with and without inclusion of epilepsy as a feature. Median F1 scores were 0.67 in 4-class comparison, and 1.0 in the binary classification, outperforming Linear-Discriminant-Analysis (0.57 and 0.86, respectively). Conclusion: This novel algorithm was able to classify study participants with spastic CP and/or epilepsy from controls with significant performance. The algorithm shows promise for rapid identification in methylation data of diagnostic methylation loci. In this model, Support Vector Machines outperformed Linear Discriminant Analysis in classification. In the evaluation of epigenetics-based diagnostics for CP, epilepsy may not be a significant confounding factor.

Hemiplegic (unilateral) cerebral palsy in northern Stockholm: Intellectual disability and epilepsy.

PURPOSE: The purpose of this study was to describe intellectual disability and its association with epilepsy and brain imaging, in a population-based group of children with hemiplegic (unilateral) cerebral palsy, previously investigated and published in 2020. MATERIALS AND METHODS: Forty-seven children of school age in northern Stockholm, fulfilling the Surveillance of Cerebral Palsy in Europe-criteria of hemiplegic (unilateral spastic) cerebral palsy, were invited to participate in the study. Twenty-one children consented to participate. A WISC (Wechsler Intelligence Scale for Children)-test was performed by an experienced psychologist. RESULTS: In the study population of twenty-one children, 57 % (n 12) displayed uneven cognitive profiles, 38 % (n 8) intellectual disability and 62 % (n 13) had a normal IQ. 43 % (n 9) developed epilepsy. Children with extensive brain lesions had more severe intellectual disability. CONCLUSIONS: In this study intellectual disability and/or epilepsy were associated with the type and extent of the underlying brain lesion. Intellectual disability and uneven cognitive profiles were common. We therefore recommend individual cognitive assessment to ensure an optimal school start.

Selective voluntary motor control influences knee joint torque, work and power in children with spastic cerebral palsy.

BACKGROUND: Children with spastic cerebral palsy (CP) have damage to the corticospinal tracts that are responsible for selective motor control (SMC). Force, velocity and timing of joint movement are related biomechanical features controlled by the corticospinal tracts (CSTs) that are important for skilled movement. RESEARCH QUESTION: Does SMC influence knee joint biomechanics in spastic CP? METHODS: In this prospective study, relationships between SMC and knee biomechanics (peak torque, total work, average power) across a range of velocities (0-300 deg/s) were assessed using an isokinetic dynamometer in 23 children with spastic CP. SMC was assessed using Selective Control Assessment of the Lower Extremity (SCALE). Logistic and linear regression models were used to evaluate relationships between SCALE and biomechanical measures. RESULTS: The ability to produce knee torque diminished with increasing velocity for both Low (0-4 points) and High (5-10 points) SCALE limb score groups (p < 0.01). More knees in the High group produced extension torque at 300 deg/s (p < 0.05) and flexion torque at 30, 90,180, 240 and 300 deg/s (p < 0.05). The ability to produce torque markedly decreased above 180 deg/s for Low group flexion. For knees that produced torque, significant positive correlations between SCALE limb scores and joint torque (0 and 120 deg/s), work (120 deg/s) and power (120 deg/s) were found (p < 0.05). Greater knee torque, work and power for the High group was found for the extensors at most velocities and the flexors for up to 120 deg/s (p < 0.05). Few Low group participants generated knee flexor torque above 120 deg/s limiting comparisons. SIGNIFICANCE: Biomechanical impairments found for children with low SMC are concerning as skilled movements during gait, play and sport activities occur at high velocities. Differences in SMC should be considered when designing individualized assessments and interventions.

Quiet standing and anteroposterior limits of stability in adolescents and young adults with bilateral spastic cerebral palsy.

Stance stability in individuals with bilateral spastic cerebral palsy (BSCP) in various standing postures including the quiet standing (QS) and limits of stability (LoS) has been widely studied. However, the relationships between the QS and LoS remain unclear. This study aimed to determine the relationships between the positions and postural sway in the QS and anteroposterior LoS in individuals with BSCP. It included 27 adolescents and young adults with BSCP (BSCP group) and 27 adolescents and young adults without disability (control group). The position of center of pressure in the anteroposterior direction (CoPy position) and the path length of center of pressure (CoP path length) during the QS and the anterior and posterior LoS (A-LoS and P-LoS, respectively) were measured using a force platform. The CoPy positions in the A-LoS and P-LoS in the BSCP group were limited compared with those in the control group. In the BSCP group, the more anterior the CoPy position in the QS, the more anterior (i.e., limited) it was in the P-LoS. Although the CoP path length in the QS was larger in the BSCP group, those in the A-LoS and P-LoS were larger in the control group. The BSCP group also showed that the more anterior the CoPy position or the longer the CoP path length in the QS, the more decreased the anteroposterior LoS range was. Therefore, assessing various standing postures, including QS and anteroposterior LoS, is important to manage balance impairments in individuals with BSCP.

Analysis of Traditional Chinese Medicine Symptoms in Children with Spastic Cerebral Palsy: A Data Mining Study.

Background: Cerebral palsy (CP) ranks as a major cause of motor disabilities in children, with spastic CP making up roughly 70-80% of all CP cases. The primary objective of our study is to identify characteristics of Traditional Chinese Medicine(TCM) symptom of spastic CP, thereby establishing correlations between the TCM symptom and the disease, providing a more scientific theoretical foundation for TCM treatments on spastic CP, enabling a deeper comprehension of clinical interventions, ultimately, improving rehabilitation outcomes in TCM treatment for spastic CP. Methods: We conducted a data mining study on TCM symptom of spastic CP children aged 4-14 years old treated at Xi'an Encephalopathy Hospital Affiliated to Shaanxi University of Chinese Medicine, from October 2021 to March 2023. The medical records of all eligible and complete spastic CP patients were extracted, processed for data cleansing, transformed, and subsequently analyzed to discern distinctive TCM symptom. K-Means Clustering Analysis and Association Rule Analysis were used for data mining. Results: Core symptoms identified for spastic CP encompassed "Motor Dysfunction", "Impaired Speech", "Delayed Development", "Limb Stiffness", "Rigidity in the limbs", "Intellectual Impairment", "Timidity and susceptibility to startle responses", "Muscle Wasting", and "Pale or Dull Complexion". Among the top-ranking associations of symptom, patterns emerge wherein "Motor dysfunction" intertwine with "Impaired speech", "Motor dysfunction" coexist with "Delayed development", and "Impaired speech" are accompanied by "Delayed development". Conclusion: This study identified the core symptom of spastic CP and tentatively suggests that the clinical manifestations of spastic CP are essentially consistent with the TCM pattern "liver exuberance and spleen weakness". This finding has facilitated the preliminary establishment of correlations between TCM pattern differentiation and the disease in medicine. It is anticipated that this correlation will bring tangible benefits to a larger number of children with spastic CP.

Effectiveness of simple and basic home-based exercise programs including pediatric massage executed by caregivers at their homes in the management of children with spastic cerebral palsy: A randomized controlled trial.

PURPOSE: This study aimed to assess the effectiveness of simple and basic home-based exercise programs (HEPs), including pediatric massage (PM), executed by caregivers at their homes in the management of children with spastic cerebral palsy (CP). METHODS: Sixty-eight children with spastic CP (diplegia) aged 4-12 years were randomly assigned to PM and HEP groups for a randomized controlled trial continuing from November 01, 2021 to June 2022. Parents provided home-based exercises to both groups, five times a week for 12 weeks. However, the PM group was additionally provided with PM. Modified Ashworth Scale (MAS), Gross Motor Function Measure (GMFM-88) and Gross Motor Function Classification System (GMFCS) were used for evaluation of spasticity and gross motor activity at baseline as well as after six and 12 weeks of intervention. Comparative analysis of data was carried out with SPSS-20. RESULTS: Mean age in HEP and PM groups was 6.65±2.12 and 7.09±2.22 years respectively. Data revealed homogeneity of both groups at the beginning of study. The PM group showed a statistically significant decrease in MAS scores after six and 12 weeks of intervention (p < 0.05) when compared with the HEP group, but similar changes did not happen in GMFM scores and GMFCS levels. However, comparative analysis revealed statistically significant change in GMFM scores and GMFCS levels (p < 0.05) when compared from baseline to 12 weeks of intervention in both groups. CONCLUSION: PM along with HEPs can be used effectively to reduce spasticity and to improve gross motor ability if performed for a period of at least six and 12 weeks respectively. In conjunction with HEPs, PM has better outcomes in the management of tone and movement disorders of spastic CP than HEPs alone.

Botulinum neurotoxin type A responders among children with spastic cerebral palsy: Pattern-specific effects.

AIM: To identify short-term effects of botulinum neurotoxin type A (BoNT) injections on gait and clinical impairments, in children with spastic cerebral palsy (CP), based on baseline gait pattern-specific subgroups. METHOD: Short-term effects of BoNT injections in the medial hamstrings and gastrocnemius were defined in a retrospective convenience sample of 117 children with CP (median age: 6 years 4 months; GMFCS I/II/III: 70/31/16; unilateral/bilateral: 56/61) who had received gait analyses before and 2 months post-BoNT. First, baseline gait patterns were classified. Statistical and meaningful changes were calculated between pre- and post-BoNT lower limb sagittal plane kinematic waveforms, the gait profile score, and non-dimensional spatiotemporal parameters for the entire sample and for pattern-specific subgroups. These gait waveforms per CP subgroup at pre- and post-BoNT were also compared to typically developing gait and composite scores for spasticity, weakness, and selectivity were compared between the two conditions. RESULTS: Kinematic improvements post-BoNT were identified at the ankle and knee for the entire sample, and for subgroups with apparent equinus and jump gait. Limbs with baseline patterns of dropfoot and to a lesser extent true equinus showed clear improvements only at the ankle. In apparent equinus, jump gait, and dropfoot, spasticity improved post-BoNT, without leading to increased weakness or diminished selectivity. Compared to typical gait, knee and hip motion improved in the crouch gait subgroup post-BoNT. CONCLUSION: This comprehensive analysis highlighted the importance of investigating BoNT effects on gait and clinical impairments according to baseline gait patterns. These findings may help identify good treatment responders.

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.

A preliminary study on the spasticity reduction of quadriceps after selective dorsal rhizotomy in pediatric cases of spastic cerebral palsy.

OBJECTIVE: This study aimed to evaluate the potential alleviation of quadriceps spasticity in children diagnosed with spastic cerebral palsy (CP) following selective dorsal rhizotomy (SDR). METHODS: A retrospective study was conducted on children suffering from spastic CP who underwent SDR at the Department of Neurosurgery, Shanghai Children's Hospital, from July 2018 to September 2020. Inclusion criteria comprised children exhibiting quadriceps spasticity exceeding modified Ashworth Scale grade 2. Muscle tone and motor function were assessed before the operation, at short-term follow-up and at the last follow-up after SDR. Additionally, intraoperative neurophysiological monitoring data were reviewed. RESULTS: The study comprised 20 eligible cases, where, prior to surgery, 35 quadriceps muscles exhibited spasticity exceeding modified Ashworth Scale grade 2. Following short-term and mid-term follow-up, specifically an average duration of 11 ± 2 days and 1511 ± 210 days after SDR, it was observed that muscle tension in adductors, hamstrings, gastrocnemius, and soleus decreased significantly. This reduction was accompanied by a decrease in quadriceps muscle tone in 24 out of 35 muscles (68.6%). Furthermore, the study found that intraoperative electrophysiological parameters can predict postoperative spasticity relief in the quadriceps. The triggered electromyographic (EMG) output of the transected sensory root/rootlets after single-pulse stimulation revealed that the higher the EMG amplitudes in quadriceps, the greater the likelihood of postoperative decrease in quadriceps muscle tension. CONCLUSIONS: SDR demonstrates the potential to reduce muscle spasticity in lower extremities in children diagnosed with CP, including a notable impact on quadriceps spasticity even they are not targeted in SDR. The utilization of intraoperative neurophysiological monitoring data enhances the predictability of quadriceps spasticity reduction following SDR.

OBJECTIVES: To compare the clinical effect of fast needling (without needle retaining), needle retaining acupuncture combined with occupational therapy and simple occupational therapy for hand dysfunction of spastic cerebral palsy in children. METHODS: A total of 75 children with spastic cerebral palsy were randomly divided into an occupational therapy group (25 cases), a fast needling group (25 cases, 1 case dropped out) and a needle retaining group (25 cases, 1 case dropped out). The patients in the occupational therapy group were only treated with occupational therapy for 20 min each time. The patients in the fast needling group were treated with acupuncture (without needle retaining) combined with occupational therapy, and the needle retaining group was treated with acupuncture (needle retaining) combined with occupational therapy, and acupuncture was taken at Hegu (LI 4), Houxi (SI 3), Yuji (LU 10), Waiguan (SJ 5), Jianyu (LI 15) and so on. The needles were retained for 30 min in patients of the needle retaining group. All the above treatments were performed once a day, 5 times a week for 12 weeks. The scores of fine motor function measure (FMFM) and Peabody developmental motor scale 2 (PDMS-2) were observed in patients of the three groups before and after treatment, and the safety of the fast needling group and the needle retaining group was compared. RESULTS: After treatment, the scores of FMFM and PDMS-2 in patients of the three groups were higher than those before treatment (P<0.01), and the scores of FMFM and PDMS-2 in the fast needling group and the needle retaining group were higher than those in the occupational therapy group (P<0.05, P<0.01). The incidence of acupuncture abnormalities in the fast needling group was 0.3% (5/1 440), which was lower than 1.4% (20/1 440) in the needle retaining group (P<0.05). CONCLUSIONS: Acupuncture combined with occupational therapy has better clinical effect than occupational therapy alone in improving hand dysfunction in children with spastic cerebral palsy, and there is no statistical difference in effect between fast needling acupuncture and needle retaining acupuncture, but fast needling has better safety than needle retaining acupuncture.

Optimization of Postural Control, Balance, and Mobility in Children with Cerebral Palsy: A Randomized Comparative Analysis of Independent and Integrated Effects of Pilates and Plyometrics.

The paradigm of comprehensive treatment approaches for children with cerebral palsy has gained traction, prompting clinicians to deliberate between independent and integrated treatment delivery. However, this decision-making process is often hindered by the dearth of empirical evidence available to inform optimal therapeutic strategies. This study, therefore, sought to compare the effects of Pilates-based core strengthening (PsCS), plyometric-based muscle loading (PlyoML), and their combination on postural control, balance, and mobility in children with unilateral cerebral palsy (ULCP). Eighty-one children with ULCP (age: 12-18 years) were randomized to PsCS (n = 27), PlyoML (n = 27), or a combined intervention (n = 27; equated for total sets/repetitions) group. The three interventions were applied twice/week over 12 successive weeks. Postural control (directional and overall limits of stability-LoS), balance, and mobility (Community Balance and Mobility Scale-CB&M; Functional Walking Test-FWT; Timed Up and Down Stair test-TUDS) were assessed pre- and post-intervention. The combined group exhibited greater increases in directional LoS compared to PsCS and PlyoML including the backward (p = 0.006 and 0.033, respectively), forward (p = 0.015 and 0.036, respectively), paretic (p = 0.017 and 0.018, respectively), and non-paretic directions (p = 0.006 and 0.004, respectively)], and this was also the case for overall LoS (p < 0.001 versus PsCS and PlyoML). In addition, the combined group displayed greater improvements compared to the PsCS and PlyoML groups regarding CB&M (p = 0.037 and p = 0.002, respectively), FWT (p = 0.012 and p = 0.038, respectively), and TUDS (p = 0.046 and p = 0.021, respectively). In conclusion, the combined PsCS and PlyoML exercise program promotes considerably greater improvements in postural control, balance, and mobility compared to unimodal training in children with ULCP.

Correlations between Trunk Control and Balance in Children with Bilateral Spastic Cerebral Palsy.

Impairments of postural responses are a salient feature of children with cerebral palsy (CP). While the systems approach describes balance in seven components, the relationship between trunk control and balance in children with CP has not been previously examined with all seven of these components. In this study, we aimed to identify correlations between trunk control and all seven systems approach balance components in children with bilateral spastic CP. Our participants were 30 children (M age = 11.83, SD = 2.32 years) with CP having a Gross Motor Function Classification System level ranging from I to III. We assessed trunk control with the Trunk Control Measurement Scale, including static and dynamic balance (selective voluntary control and reaching). Balance in standing was assessed using Kids-Mini-BESTest involving four domains: anticipatory, reactive, sensory orientation and stability in gait. We used Spearman's rank correlations to correlate trunk control and balance, and we obtained a moderate correlation between the trunk control measurement scale and the Kids-Mini-BESTest in children with both bilateral spastic CP (rs = .618, p < .001) and spastic diplegic CP (rs = .52, p = .02). Analysis of the correlations between separate domains of the Kids-Mini-BESTest and the trunk control measurement scale subscales revealed moderate correlations between the static sitting balance subscale and all four domains of the Kids-Mini-BESTest. The dynamic selective motor control subscale of the trunk control measurement scale moderately correlated with the anticipatory domain of the Kids-Mini-BESTest. The dynamic reaching subscale also correlated moderately with anticipatory and stability in gait domains. This correlation was statistically significant in the 13 to 17-year-old age group and was strong among females, whereas the correlation was moderate in males. Trunk control was moderately associated with balance considering all the systems theory components of balance in children with bilateral spastic cerebral palsy.

Knowledge mapping of spastic cerebral palsy. A bibliometric analysis of global research (2000-2022).

BACKGROUND: Cerebral palsy (CP) is characterized by abnormal pronunciation, posture, and movement. Spastic CP accounts for more than 70% of all CP. To date, there has been no bibliometric analysis to summarize study on spastic CP. Here, we aim to conduct a bibliometric analysis of spastic CP to summarize this field's knowledge structure, research hotspots, and frontiers. METHOD: Publications about spastic CP were searched utilizing the Web of Science Core Collection (WoSCC) database from 1 January 2000 to 30 November 2022, the WoSCC literature analysis wire, VOSviewer 1.6.18, CiteSpace 6.1.R4 and Online analysis platform for bibliometrics were used to conduct the analysis. RESULTS: A total of 3988 publications, consisting of 3699 articles and 289 reviews, were included in our study. The United States emerged as the most productive country, while Kathleen Univ Leuven was the most productive institution. The leading author was Desloovere K. A total of 238 journals contributed to this field, with Developmental medicine and child neurology being the leading journal. Important keywords and keyword clusters included Spastic cerebral palsy, Reliability, and Gross motor function. Keywords identified through burst detection indicated that hotspots in this field were management, randomized controlled trials, and definition. CONCLUSION: Based on the analysis of bibliometric on spastic CP over the past 20 years, the trends and the knowledge graph of the countries, institutions, authors, references, and the keywords have been identified, providing accurate and expedited insights into critical information and potentially new directions in the study of spastic CP.

Detecting Asymmetry of Upper Limb Activity with Accelerometry in Infants at Risk for Unilateral Spastic Cerebral Palsy.

AIMS: To examine whether accelerometry can quantitate asymmetry of upper limb activity in infants aged 3-12 months at risk for developing unilateral spastic cerebral palsy (USCP). METHOD: A prospective study was performed in 50 infants with unilateral perinatal brain injury at high risk of developing USCP. Triaxial accelerometers were worn on the ipsilateral and contralesional upper limb during the Hand Assessment for Infants (HAI). Infants were grouped in three age intervals (3-5 months, 5-7.5 months and 7.5 until 12 months). Each age interval group was divided in a group with and without asymmetrical hand function based on HAI cutoff values suggestive of USCP. RESULTS: In a total of 82 assessments, the asymmetry index for mean upper limb activity was higher in infants with asymmetrical hand function compared to infants with symmetrical hand function in all three age groups (ranging from 41 to 51% versus - 2-6%, p < 0.01), while the total activity of both upper limbs did not differ. CONCLUSIONS: Upper limb accelerometry can identify asymmetrical hand function in the upper limbs in infants with unilateral perinatal brain injury from 3 months onwards and is complementary to the Hand Assessment for Infants.

Effect of exercise rehabilitation and adapted physical activity on psychomotor skills, motor abilities and motor development in children and adolescents with spastic cerebral palsy: an evidence-based research using ICF / 中国康复理论与实践

ObjectiveTo systematically review the evidences of impact of exercise rehabilitation and adapted physical activity on psychomotor skills, motor abilities, and motor development in children with spastic cerebral palsy (CP). MethodsRelevant literature was retrieved from PubMed, Embase, Web of Science and CNKI, from January, 2010 to June, 2023. The contents were coded using International Classification of Diseases, Eleventh Revision, and International Classification of Functioning, Disability and Health; and evidences were analyzed with theoretical framework and code of ICD-11 and ICF. ResultsA total of nine articles were included, from Denmark, South Korea, Australia, Saudi Arabia, Ghana, India and Japan, published from 2015 to 2022. The intervention programs primarily involved exercise rehabilitation (including physical therapy) and adapted physical activity. Exercise rehabilitation included upper limb strength training, lower limb strength training, balance and coordination training, gait training, functional aerobic exercise, stretching and flexibility exercises, flexibility training, muscle relaxation techniques; ten to 50 minutes a time, two to six times a week,with the intensity of low to high, for six to 20 weeks. Adapted physical activities mainly involved adapted running training, virtual games; 60 minutes a time, two to four times a week, with the intensity of medium to high, for six to twelve weeks. Interventions primarily took place in medical and rehabilitation institutions, schools, and home-based communities, with professionals including occupational physical therapists, university researchers, community health personnel and teachers. The outcomes were mainly reflected in four aspects: psychomotor skills, motor abilities, motor development, and quality of life and well-being. In terms of psychomotor skills, adolescents with CP mastered running techniques and knowledge, and enhanced their response to balance threats. In terms of motor abilities, adolescents with CP showed an increase in muscle strength, enhanced muscle endurance, and an expansion of muscle tone; improvements in gait functionality, walking ability, and gait symmetry; increases in walking endurance; improvements in standing function; and improvements in dynamic balance; as well as enhanced control over balance posture. In terms of motor development, there was a significant improvement in activities of daily living, participation levels in school and leisure activities during free time, and an expanded range of motion. In terms of quality of life and well-being, adolescents with CP showed significant enhancements in self-confidence and self-esteem, significant relief from (spastic) pain, and improvements in social well-being and acceptance. ConclusionThis systematic review has synthesized the evidences of benefits of exercise rehabilitation and adapted physical activity on the psychomotor skills, motor abilities and motor development of children and adolescents with spastic CP. In terms of psychomotor skills, exercise rehabilitation and adapted physical activity help to improve the cognitive and motor skills of adolescents with spastic CP. In terms of motor abilities, exercise rehabilitation and adapted physical activity can improve muscle-related functions, gait and walking abilities, as well as balance and coordination. In terms of motor development, exercise rehabilitation and adapted physical activity significantly enhance activities of daily living and the level of participation in leisure physical activities. Finally, exercise rehabilitation and adapted physical activity can increase energy and motivation, alleviate pain, and enhance social well-being and acceptance.

Effect of physical training on motor function of ambulant children with diplegia after selective dorsal rhizotomy: A randomized controlled study.

BACKGROUND: Children with spastic diplegia experience tonicity, lack of selective motor control, subnormal postural stability and delayed motor development. Selective dorsal rhizotomy followed by physical therapy is a permanent procedure aimed to alleviate hypertonicity. OBJECTIVE: To explore the efficacy of selective dorsal rhizotomy (SDR) followed by a physical training on gross motor function (GMF), functional balance, walking capacity, selective motor control (SMC) and energy cost of walking (ECW) of ambulant children with spastic diplegia. METHODS: Forty-two children with spastic diplegia aged 5 to 8 years were randomly assigned into the control or SDR-group. Both groups received a designed physical training of progressive functional strength training and standard orthotic management (SOM) 3 times a week for 6 months. GMF, functional balance, ECW, functional capacity and SMC were assessed by gross motor function measure (GMfM-88), pediatric balance scale (PBS), energy expenditure index (EEI), six-minute walking test (6MWT) and selective control assessment of lower extremity (SCALE), respectively. Assessment was carried out before the treatment (baseline), after 6 months (post I) and 1-year follow-up (post II). RESULTS: From baseline to post I and post II assessments, changes of GMF, functional balance, ECW, functional capacity and SMC within the control and SDR groups showed significant improvements (P < 0.001). Moreover, group comparison showed significant differences in favor of the SDR group. CONCLUSION: Integrated physical training followed SDR demonstrated qualitative changes and enhancement in motor function, achieved by spasticity reduction.

Safety and Efficacy of Botulinum Toxin Type A in Children With Spastic Cerebral Palsy Aged <2 Years: A Systematic Review.

In this study, we reviewed the safety and efficacy of botulinum toxin type A (BoNT-A) injection with respect to motor development in children with spastic cerebral palsy aged <2 years. Randomized controlled trials of BoNT-A published between July 1993 and May 2021 were searched in PubMed, WANFANG, CNKI (Chinese National Knowledge Infrastructure), and Cochrane Library Central Register of Controlled Trials using keywords "Botulinum Toxin," "cerebral palsy," "nao xing tan huan," "nao tan," and "rou du du su." The 11-item PEDro Scale was used to rate the quality of all the identified studies. Twelve studies, involving 656 subjects, met the inclusion criteria, and of these, 2 involved patients aged <2 years. Treatment safety was assessed based on adverse event (AE) number and frequency, and efficacy was assessed based on spasticity, range of movement, and motor development. We observed that 3 self-limiting adverse events that were frequently reported included weakness, dysesthesia of the skin, and pain at the injection site. Moreover, there was a significant decrease in the incidence of spasticity and a notable improvement in the range of movement of BoNT-A-treated patients. Therefore, BoNT-A injection shows great safety and efficacy in the treatment of children with cerebral palsy aged <2 years.

Influence of the percutaneous myofasciotomy on gait of children with spastic cerebral palsy - A short term, retrospective controlled analysis.

BACKGROUND: One of the primary causes in children with cerebral palsy (CP) leading to gait disorders is an increased muscle tone which may secondary result in a shortening of the muscle fascia. Percutaneous myofasciotomy (pMF) is a minimal-invasive surgical intervention correcting the shortened muscle fascia and aims to extend the range of motion. RESEARCH QUESTION: What is the effect of pMF on gait in children with CP three months and one year post-OP? METHODS: Thirty-seven children (f: n = 17, m: n = 20; age: 9,1 ± 3,9 years) with spastic CP (GMFCS: I-III, bilateral (BSCP): n = 24, unilateral (USCP): n = 13) were retrospectively included. All children underwent a three dimensional gait analysis with the Plug-in-Gait-Model before (T0) and three months after pMF (T1). Twenty-eight children (bilateral: n = 19, unilateral: n = 9) underwent a one-year follow-up-measurement (T2). Differences in the Gait Profile Score (GPS), kinematic gait data, gait-related functions and mobility in daily living were statistically analyzed. Results were compared to a control group (CG) matched in age (9,5 ± 3,5 years), diagnosis (BSCP: n = 17; USCP: n = 8) and GMFCS-level (GMFCS I-III). This group was not treated with pMF but underwent two gait analyses in twelve months. RESULTS: The GPS improved significantly in BSCP-pMF (16,46 ± 3,71° to 13,37 ± 3,19°; p < .0001) and USCP-pMF (13,24 ± 3,27° to 10,16 ± 2,06°; p = .003) from T0 to T1 with no significant difference between T1 and T2 in both groups. In CG there was no difference in the GPS between the two analyses. SIGNIFICANCE: PMF may in some children with spastic CP improve gait function three months as well as for one-year post-OP. Medium and long-term effects, however, remain unknown and further studies are needed.

Quantitative identification of ventral/dorsal nerves through intraoperative neurophysiological monitoring by supervised machine learning.

Objective: This study aimed to investigate the electro-neurophysiological characteristics of the ventral and dorsal nerves at the L2 segment in a quantitative manner. Methods: Medical records of consecutive patients who underwent single-level approach selective dorsal rhizotomy (SDR) from June 2019 to January 2022 were retrospectively reviewed. Intraoperative electro-neurophysiological data were analyzed. Results: A total of 74 males and 27 females were included in the current study with a mean age of 6.2 years old. Quadriceps and adductors were two main muscle groups innervated by L2 nerve roots in both ventral and dorsal nerve roots. Dorsal roots have a higher threshold than that of the ventral ones, and muscles that first reached 200 µV innervated by dorsal roots have longer latency and smaller compound muscle action potential (CMAP) than those of the ventral ones. Supervised machine learning can efficiently distinguish ventral/dorsal roots using threshold + latency or threshold + CMAP as predictors. Conclusion: Electro-neurophysiological parameters could be used to efficiently differentiate ventral/dorsal fibers during SDR.
