This study aimed to investigate if voluntary participation in robot-assisted gait training leads to more concentrated muscle activity patterns and clinical measure improvements. A single-participant research design study was conducted with a gradual reduction in robotic assistance during robot-assisted gait training. A child with cerebral palsy participated in 20 robot-assisted gait training sessions and two assessment sessions across 99 days. The assistive force of the Lokomat gradually reduced during repeated training. The effects of reduced assistive force on muscle activity patterns were quantitatively analyzed using a clustering algorithm and electromyography. Improvements in overall gait quality and muscle strength were measured after robot-assisted gait training. The results also showed that the number of clustered representative patterns doubled and muscle activation patterns increased when the assistance decreased by 20%, whereas full robot assistance might have hindered active participation. Since assistive force modulation can be a key in robotic rehabilitation, the proposed protocol, involving gradual assistive force reduction, demonstrates promising efficacy and allows for in-depth analysis. Therefore, further randomized clinical trials based on this study can be possible for children with cerebral palsy. Full article

Background and Purpose: activities-based locomotor training (AB-LT) is a restorative therapeutic approach to the treatment of movement deficits in people with non-progressive neurological conditions, including cerebral palsy (CP). Transcutaneous spinal stimulation (TSS) is an emerging tool in the rehabilitation of individuals with sensorimotor deficits caused by neurological dysfunction. This non-invasive technique delivers electrical stimulation over the spinal cord, leading to the modulation of spinal sensorimotor networks. TSS has been used in combination with AB-LT and has been shown to improve muscle activation patterns and enhance motor recovery. However, there are no published studies comparing AB-LT + TSS to AB-LT alone in children with CP. The purpose of this case study was to compare the impact of AB-LT alone versus AB-LT combined with TSS on functional movement and quality of life in a child with CP. Methods: A 13-year-old male with quadriplegic CP participated in this pilot study. He was classified in the Gross Motor Function Classification System (GMFCS) at Level III. He completed 20 sessions of AB-LT (5x/week), then a 2-week washout period, followed by 20 sessions of body-AB-LT + TSS. Treatment sessions consisted of 1 h of locomotor training with body weight support and manual facilitation and 30 min of overground play-based activities. TSS was applied using the RTI Xcite^®, with stimulation at the T11 and L1 vertebral levels. Assessments including the Gross Motor Function Measure (GMFM), 10-m walk test (10 MWT), and Pediatric Balance Scale (PBS) were performed, while spatiotemporal gait parameters were assessed using the Zeno Walkway^®. All assessments were performed at three time points: before and after AB-LT, as well as after AB-LT + TSS. OUTCOMES: After 19/20 sessions of AB-LT alone, the participant showed modest improvements in the GMFM scores (from 86.32 to 88), 10 MWT speed (from 1.05 m/s to 1.1 m/s), and PBS scores (from 40 to 42). Following the AB-LT combined with TSS, scores improved to an even greater extent compared with AB-LT alone, with the GMFM increasing to 93.7, 10 MWT speed to 1.43 m/s, and PBS to 44. The most significant gains were observed in the GMFM and 10 MWT. Additionally, improvements were noted across all spatiotemporal gait parameters, particularly at faster walking speeds. Perhaps most notably, the child transitioned from the GMFCS level III to level II by the end of the study. Discussion: Higher frequency and intensity interventions aimed at promoting neuroplasticity to improve movement quality in children with CP are emerging as a promising alternative to traditional physical therapy approaches. This case study highlights the potential of TSS to augment neuroplasticity-driven treatment approaches, leading to improvements in neuromotor function in children with CP. These findings suggest that TSS could be a valuable addition to rehabilitation strategies, warranting further research to explore its efficacy in larger populations. Full article

Background/Objectives: Cerebral palsy (CP) affects a substantial number of children, particularly in low- and middle-income countries such as Bangladesh. Maternal health literacy is critical to the health and well-being of children with CP, particularly in low-resource settings. In this study, we sought to assess how the mPower (mother’s power) community-based intervention impacted mothers’ CP-specific knowledge, as well as their utilization of rehabilitation services in rural Bangladesh. Methods: This quasi-experimental study was conducted with a group of mothers of children with CP, formed through the ongoing initiatives of the Bangladesh CP Register in rural Bangladesh. A pre-post-intervention comparison method was used to assess the outcomes of the intervention. Results: Mothers who participated in over two-thirds of the mPower sessions demonstrated a significant increase in CP-related knowledge (75.5% vs. 63.6%, p = 0.04). Additionally, mothers who attended two-thirds of the mPower sessions utilized rehabilitation services more often compared to those who attended fewer sessions (55.3% vs. 22.6%, p < 0.001). Conclusions: The mPower intervention successfully improved health literacy and likely increased rehabilitation service utilization among mothers of children with CP in rural Bangladesh. Full article

Context: Spastic cerebral palsy (SCP) is a condition characterized by muscle stiffness and involuntary movements, which greatly affect movement abilities and overall well-being. Low-level laser therapy (LLLT) has emerged as a treatment option for managing spasticity, though the current evidence varies. Objective: This systematic review seeks to assess the efficacy of LLLT on spasticity in children with cerebral palsy. We hope it will pinpoint areas where more research is needed and suggest directions for future studies. Method: A search of the literature was performed across databases, such as PubMed, Google Scholar, Scopus, and Elicit. The search utilized keywords and the Medical Subject Headings (MeSH) terms. Only studies conducted in English that focused on children with cerebral palsy (CP) and explored the effects of LLLT on spasticity were considered. The quality of the selected studies was evaluated using assessment tools. Results: The search identified 534 references, out of which eight studies met the screening criteria for inclusion. All cited papers indicated reductions in spasticity with further mention of reduced pain and greater muscle strength by some authors. Conclusions: This review indicates that LLLT shows promise in decreasing spasticity in children with cerebral palsy. Nevertheless, a lack of treatment parameters, heterogeneity in research methods, and a lack of objective outcome measures weaken the results. This review underscores the importance of standardized procedures and carefully planned randomized controlled trials to establish conclusive findings on the effectiveness of LLLT in this population.

Background/Objectives: To describe social and psychological needs, such as poverty, early trauma, or adverse childhood events, of caregivers with a child newly diagnosed with cerebral palsy (CP) or receiving a designation of high-risk for cerebral palsy (HRCP). Methods: Caregiver self-report questionnaires screening for unmet social needs, adverse childhood experiences (ACEs), depression symptoms, and trauma were collected from 97 caregivers of children with CP/HRCP seen in a high-risk infant follow-up clinic (adjusted age range 1–24 months). We compared their responses to those of 97 caregivers of age-matched controls seen in the same clinic with similar risk factors over the equivalent time period. Results: Income insecurity and positive screening rate for depressive and trauma symptoms were high for both groups (CP/HRCP, matched control group); no differences were found between CP/HRCP and control groups. Rates of food and housing insecurity and caregiver ACEs were not different between groups. All families received referrals to appropriate community support at the visit. Conclusions: Caregivers of children with CP/HRCP in high-risk infant follow-up clinics may face difficult conversations and decision-making in the context of high psychological and social adversity. Comprehensive support should be considered as early as possible. Full article

Clonus is characterized by involuntary, rhythmic, oscillatory muscle contractions, typically triggered by rapid muscle stretching and is frequently associated with spastic equinovarus foot (SEVF), where it may increase risk of falls and cause discomfort, pain, and sleep disorders. We hypothesize that selective diagnostic nerve block (DNB) of the tibial nerve motor branches can help identify which muscle is primarily responsible for clonus in patients with SEVF and provide useful information for botulinum neurotoxin type A (BoNT-A) treatment. This retrospective study explored which calf muscles contributed to clonus in 91 patients with SEFV after stroke (n = 31), multiple sclerosis (n = 21), and cerebral palsy (n = 39), using selective DNB. We found that SEVF-associated clonus was most commonly driven by the soleus muscle, followed by the gastrocnemius lateralis and medialis, tibialis posterior, and flexor digitorum longus, and that frequency differed according to SEVF etiology. Our data suggest that identifying the muscles involved in SEVF-associated clonus may aid clinicians in personalizing BoNT-A treatment to single patients. Also, the findings of this study suggest that applying a ‘stroke model’ to treating spasticity secondary to other etiologies may not always be appropriate. Full article

Globally, around 1 in 10 children aged 0–17 years have moderate-to-severe disabilities. The aquatic environment provides hydrostatic and hydrodynamic characteristics that make exercise and therapy feasible for children and adolescents with disabilities. The objective of this scoping review is to understand the extent and type of evidence in relation to the use of aquatic therapy in children and adolescents with disabilities. The eligibility criteria were as follows: participants—children and/or adolescents with disabilities aged from 6 to 18 years old; concept—aquatic therapy interventions; context—any available setting. The databases searched included MEDLINE, CINAHL, EMBASE, PsycINFO, AMED, Eric, Scopus, Web of Science, Epistemonikos, and one register, Cochrane Central Register of Controlled Trials. In total, 52 reports met the inclusion criteria. Most of the studies included children/adolescents with autism spectrum disorder (ASD; 46.7%)—442 participants in 21 studies in total. The majority of interventions were based on aquatic exercise (35%). Most often, interventions were conducted for 8 weeks, with 2 sessions a week lasting 60 min. The most common type of intervention for children and adolescents with ASD and Down syndrome was swimming. Participants with attention deficit hyperactivity disorder, neuromuscular disorders, and cerebral palsy were more often treated with aquatic exercises. This scoping review could guide practitioners, clinicians, and researchers on what type, setting, and content of aquatic therapy interventions, including exercise types, intervention duration, number of sessions, frequency, facility, and provider, are used with children and adolescents with disabilities.

Early detection and rehabilitation interventions are essential to optimise motor function in infants and young children with unilateral cerebral palsy. In this paper we report a clinical framework aimed at enhancing upper limb therapy for infants and young children with unilateral cerebral palsy during a sensitive period of brain development. We describe two major therapeutic approaches based on motor learning principles and evidence: constraint-induced movement therapy and bimanual therapy. These two therapies have demonstrated efficacy in older children and emerging evidence is available for their application to infants younger than 2 years of age. To provide clinicians with guidance as to when to implement these therapies, we discuss the key consideration when undertaking upper limb therapy programs. In addition, we describe the factors to consider when choosing which approach may be suitable for an individual child and family. Detailed strategies for implementing these therapies in infants and young children of different ability levels are given. Full article

Objective: To evaluate neurogenic bladder and bowel dysfunction (NBBD) in children with cerebral palsy (CP) and acquired brain injury (ABI), a condition considered less frequent in those patients than in children with spinal cord injury (SCI), and to study the relationship between NBBD and disability grade in this population. Study Design: We retrospectively reviewed the clinical data of all patients (aged 3–18 years old) admitted during a three-month observation in our neurorehabilitation department. Data collected were as follows: demographic parameters; disability status (Wee-FIM Scale, Gross Motor Function Classification System (GMFCS) and the Communication Function Classification System); and gastrointestinal and urological symptoms (diaries, Bristol scale, Pad Test and International Consultation on Incontinence Modular Questionnaire). Results: Sixty patients were enrolled (31 females, 29 males): 30 CP, 17 ABI, 3 SCI, and 10 others with neurological diseases. All presented urinary incontinence without gender differences. CP and ABI had major incidences of bowel dysfunction (50% and 64.7%, respectively) and SCI of urinary tract infections (66.6%) and enuresis (100%). A major incidence of symptoms was recorded in patients with higher GMFCS levels (level 3-4-5). Conclusions: NBBD has a high frequency in children with CP and ABI, as in SCI. More attention is needed from pediatricians and pediatric urologists for this clinical entity. Further studies are needed to better understand clinical relevance and, therefore, to establish specific management. Full article

Perinatal asphyxia (PA) is a clinical condition characterized by oxygen supply suspension before, during, or immediately after birth, and it is an important risk factor for neurodevelopmental damage. Its estimated 1/1000 live births incidence in developed countries rises to 5–10-fold in developing countries. Schizophrenia, cerebral palsy, mental retardation, epilepsy, blindness, and others are among the highly disabling chronic pathologies associated with PA. However, so far, there is no effective therapy to neutralize or reduce PA-induced harm. Selective regulators of estrogen activity in tissues and selective estrogen receptor modulators like raloxifene have shown neuroprotective activity in different pathological scenarios. Their effect on PA is yet unknown. The purpose of this paper is to examine whether raloxifene showed neuroprotection in an oxygen–glucose deprivation/reoxygenation astrocyte cell model. To study this issue, T98G cells in culture were treated with a glucose-free DMEM medium and incubated at 37 °C in a hypoxia chamber with 1% O₂ for 3, 6, 12, and 24 h. Cultures were supplemented with raloxifene 10, and 100 nM during both glucose and oxygen deprivation and reoxygenation periods. Raloxifene 100 nM and 10 nM improved cell survival—65.34% and 70.56%, respectively, compared with the control cell groups. Mitochondrial membrane potential was preserved by 58.9% 10 nM raloxifene and 81.57% 100 nM raloxifene cotreatment. Raloxifene co-treatment reduced superoxide production by 72.72% and peroxide production by 57%. Mitochondrial mass was preserved by 47.4%, 75.5%, and 89% in T98G cells exposed to 6-h oxygen–glucose deprivation followed by 3, 6, and 9 h of reoxygenation, respectively. Therefore, raloxifene improved cell survival and mitochondrial membrane potential and reduced lipid peroxidation and reactive oxygen species (ROS) production, suggesting a direct effect on mitochondria. In this study, raloxifene protected oxygen–glucose-deprived astrocyte cells, used to mimic hypoxic–ischemic brain injury. Two examiners performed the qualitative assessment in a double-blind fashion.

Due to the complexity of the medical issues connected with cerebral palsy (CP), the classification of gait pathologies seems rather difficult. The aim of this study was to asses the usefulness of the Gait Kinematics Index (GKI) from a clinical point of view in the population of patients with CP. The assessment of the possibilities of using the GKI in a group of patients with CP was conducted on the basis of the correlation of its results with the Gillette Gait Index (GGI) and Gait Deviation Index (GDI) values. The distribution of the index values was also evaluated with attention paid to the CP types and treatment methods. Analyses were performed on the basis of the gait test results in a group of 56 healthy children and 72 patients with CP. The GKI values for patients with CP were 1.55 ± 0.66, as opposed to 0.77 ± 0.17 for the reference group. A strong linear correlation was found between the values of the GKI and GGI (r = 0.8 ÷ 0.85), as well as between the GKI and GDI (r = −0.89 ÷ 0.9), obtained in children with CP. In addition, significant differences were found between the results obtained in all the groups of children with CP divided by treatment method (rehabilitation, botulinum, rhizotomy, p < 0.05), whereas in the groups of children divided by CP type, significant differences (p < 0.05) were found solely between diplegia and hemiplegia and between hemiplegia and quadriplegia. The results obtained were the same in the case of the GKI, GGI and GDI. To conclude, the results presented in this work confirm the clinical utility of the GKI in the population of patients with CP.

Background: The first stage of childhood is characterized by great neuronal plasticity. In Unilateral Cerebral Palsy (UCP), it is essential to carry out early treatment, with family involvement. The aim of this study was to investigate the feasibility of Early Infant Hybrid Therapy (eI-Hybrid) applied at home with family involvement in children with UCP aged 9–18 months, and to assess its preliminary effectiveness on bimanual functional performance. Methods: A single group of 10 children (12.8 months, SD = 3.4) performed the eI-Hybrid therapy. The main outcome was measured with the mini Assisting Hand Assessment scale (mini-AHA), functional goals were measured with the Goal Attainment Scale (GAS), and satisfaction expectations on intensive therapy were also recorded. Three measures were performed (week 0, week 10, and month 6). A repeated-measures ANOVA test was performed on the mini-AHA in order to observe the statistically significant differences in pairwise comparison. Results: Ten children completed the study and the parents’ expectations were fulfilled, indicating high caregiver compliance and high adherence to the treatment. Clinically relevant changes were observed between pre- and post-intervention measurements in BFP (pre: 41.9 (SD: 7.7), post: 50.9 (SD: 6.0) and in the follow-up at 6 months (50.3 (SD:5.6); p < 0.001). Families reported a high satisfaction. Conclusions: infant hybrid treatment is feasible to be performed at home with the family’s involvement, obtaining improvements in the affected upper limb for early-age UCP. Full article

Hypoxic–ischemic encephalopathy (HIE) is a perinatal brain injury that is the leading cause of cerebral palsy, developmental delay, and poor cognitive outcomes in children born at term, occurring in about 1.5 out of 1000 births. The only proven therapy for HIE is therapeutic hypothermia. However, despite this treatment, many children ultimately suffer disability, brain injury, and even death. Barriers to implementation including late diagnosis and lack of resources also lead to poorer outcomes. This demonstrates a critical need for additional treatments for HIE, and to facilitate this, we need translational models that accurately reflect risk factors and interactions present in HIE. Maternal or amniotic infection is a significant risk factor and possible cause of HIE in humans. Maternal immune activation (MIA) is a well-established model of maternal infection and inflammation that has significant developmental consequences largely characterized within the context of neurodevelopmental disorders such as autism spectrum disorder and schizophrenia. MIA can also lead to long-lasting changes within the neuroimmune system, which lead to compounding negative outcomes following a second insult. This supports the importance of understanding the interaction of maternal inflammation and hypoxic–ischemic outcomes. Animal models have been invaluable to understanding the pathophysiology of this injury and to the development of therapeutic hypothermia. However, each model system has its own limitations. Large animal models such as pigs may more accurately represent the brain and organ development and complexity in humans, while rodent models are more cost-effective and offer more possible molecular techniques. Recent studies have utilized MIA or direct inflammation prior to HIE insult. Investigators should thoughtfully consider the risk factors they wish to include in their HIE animal models. In the incorporation of MIA, investigators should consider the type, timing, and dose of the inflammatory stimulus, as well as the timing, severity, and type of hypoxic insult. Using a variety of animal models that incorporate the maternal–placental–fetal system of inflammation will most likely lead to a more robust understanding of the mechanisms of this injury that can guide future clinical decisions and therapies.

Introduction: Performance in a single step has been suggested to be a sensitive measure of movement quality in pediatric clinical populations. Although there is less information available in children with typical development, researchers have postulated the importance of analyzing the effect of body weight modulation on the initiation of stair ascent, especially during single-limb stance where upright stability is most critical. The purpose of this study was to investigate the effect of load modulation from −20% to +15% of body weight on typical pediatric lower limb joint moments during a step-up task. Methods: Fourteen participants between 5 and 21 years who did not have any neurological or musculoskeletal concerns were recruited to perform multiple step-up trials. Peak extensor support and hip abduction moments were identified during the push-off and pull-up stance phases. Linear regressions were used to determine the relationship between peak moments and load. Mixed-effects models were used to estimate the effect of load on hip, knee, and ankle percent contributions to peak support moments. Results: There was a positive linear relationship between peak support moments and load in both stance phases, where these moments scaled with load. There was no relationship between peak hip abduction moments and load. While the ankle and knee were the primary contributors to the support moments, the hip contributed more than expected in the pull-up phase. Discussion: Clinicians can use these results to contextualize movement differences in pediatric clinical populations, including in those with cerebral palsy, and highlight potential target areas for rehabilitation for populations such as adolescent athletes.

Background/Objectives: Clinical trials have investigated the efficacy of rehabilitation robotics for various pathological conditions, but the overall impact on rehabilitation practice remains unclear. We comprehensively examined and analyzed systematic reviews (SRs) of randomized controlled trials (RCTs) investigating rehabilitative interventions with robotic devices. Methods: Four databases were searched using term combinations of keywords related to robotic devices, rehabilitation, and SRs. The SR meta-analyses were categorized into “convincing”, “highly suggestive”, “suggestive”, “weak”, or “non-significant” depending on evidence strength and validity. Results: Overall, 62 SRs of 341 RCTs involving 14,522 participants were identified. Stroke was most frequently reported (40 SRs), followed by spinal cord injury (eight SRs), multiple sclerosis (four SRs), cerebral palsy (four SRs), Parkinson’s disease (three SRs), and neurological disease (any disease causing limited upper- and lower-limb functioning; three SRs). Furthermore, 38, 21, and 3 SRs focused on lower-limb devices, upper-limb devices, and both upper- and lower-limb devices, respectively. Quantitative synthesis of robotic intervention effects was performed by 51 of 62 SRs. Robot-assisted training was effective for various outcome measures per disease. Meta-analyses offering suggestive evidence were limited to studies on stroke. Upper-limb devices were effective for motor control and activities of daily living, and lower-limb devices for walking independence in stroke. Conclusions: Robotic devices are useful for improving impairments and disabilities in several diseases. Further high-quality SRs including RCTs with large sample sizes and meta-analyses of these RCTs, particularly on non-stroke-related diseases, are required. Further research should also ascertain which type of robotic device is the most effective for improving each specific impairment or disability. Full article
