Efficacy of verbal suggestion, verbal suggestion with a tuning fork, and verbal suggestion with a cotton swab for inducing the paroxysmal event during video-EEG recording in children with suspected psychogenic nonepileptic seizures.

INTRODUCTION: Video-electroencephalogram (EEG) with suggestion is widely considered the gold standard for diagnosing psychogenic nonepileptic seizures (PNES). However, ethical concerns and uncertainties persist regarding the most minimally invasive and least deceptive suggestion approach. MATERIALS AND METHODS: In an open-label randomized controlled trial, we evaluated the effectiveness of three suggestion methods (verbal suggestion, verbal suggestion with a tuning fork, and verbal suggestion with a cotton swab) during short-term video-EEG (STVEEG) recordings to induce PNES in children aged 5-18 years. If the paroxysmal event couldn't be elicited with the assigned method, alternative techniques were employed. RESULTS: Out of 97 initially screened children, 75 were enrolled, with 25 in each group. The efficacy of all three suggestion methods was comparable in reproducing paroxysmal events (success rate of 16/25, 17/25 and 17/25 in verbal suggestion only, verbal suggestion with tuning fork and sterile cotton swab group respectively, p = 0.83) and the time required for induction (median of 2, 3 and 3 min respectively, p = 0.21). After trying alternative methods, 20 %, 12 %, and 12 % more patients in these three groups, respectively, were able to reproduce the paroxysmal event, with the differences not reaching statistical significance (p = 0.74). The assigned induction method or the success/failure of event reproduction did not significantly impact clinical outcomes at 12 weeks, and none of the patients in whom PNES could not be reproduced during STVEEG were later found to have an organic cause. Only the presence of psychiatric comorbidity independently predicted successful event reproduction during STVEEG, with statistical significance even after adjusting for other variables (p = 0.03). CONCLUSION: The efficacy of verbal suggestion alone in inducing paroxysmal nonepileptic seizures is on par with using a tuning fork or cotton swab in conjunction with verbal suggestion during STVEEG.

The Childhood and Adolescent Sleep Evaluation Questionnaire (CASEQ): Development and validation of an ICSD-3-based screening instrument, a community and hospital-based study.

Sleep disorders are common in children and adolescents. Polysomnography is the gold-standard diagnostic method; however, it is a tedious procedure. The objective of the study was to develop a screening questionnaire for sleep problems based on International Classification of Sleep Disorders-3 in children and adolescents, and validate it with clinical evaluation and polysomnography. A questionnaire was developed in English and Hindi with content validation by eight multidisciplinary experts. Respondents were parents of children and adolescents, aged 2-18 years, recruited from a public school and a tertiary care teaching hospital in north India. A subset of these children and adolescents underwent overnight polysomnography and detailed clinical evaluation within 4 weeks of applying the questionnaire. The questionnaire, named Childhood and Adolescent Sleep Evaluation Questionnaire, contains primary questions covering all subgroups of disorders under International Classification of Sleep Disorders-3, and secondary questions on sleep hygiene and comorbidities. The questionnaire was filled by 750 respondents, out of which 100 cases underwent polysomnography and clinical evaluation. The internal consistency in the form of Cronbach's α was 0.8 for the questionnaire. The sensitivity, specificity, positive and negative predictive values for the questionnaire in identifying those with sleep problems compared with detailed clinical and polysomnographic evaluations were 85%, 100%, 100% and 62.5%, respectively. For individual subgroups of disorders, the sensitivity, specificity, positive and negative predictive values varied between 72.7% and 100%, 88.9% and 100%, 62.5% and 100% and 81.6% and 100%, respectively. The Childhood and Adolescent Sleep Evaluation Questionnaire has good psychometric properties, moreover, its simplicity and translatability make it ideal for use at the community and hospital settings.

Neurobehavioral deterioration associated with sleep-augmented epileptiform abnormalities: A steroid responsive state in children.

OBJECTIVE: Retrospective case record analysis of children with Neurobehavioral Deterioration associated with Sleep-augmented Epileptiform abnormalities (NDSE). METHODS: Hospital records of children with NDSE (July, 2015 through December, 2016) were analyzed. Children were categorized as: Encephalopathy with electrical status epilepticus in sleep (ESES) if sleep EEG Spike-wave-Index (SWI) was ≥50% and sleep-induced epileptiform activity (SIEA)-related cognitive dysfunction if SWI ≥25% but <50%. Demography, neurobehavior profile (IQ/SQ and behavior using validated psychometric tools), etiology, investigations and treatment details were documented. Outcome assessment was based on three-month follow-up records. RESULTS: Eighteen children with NDSE {12 boys; median age at diagnosis: 7.5 years (IQR: 6-10 years); SIEA (7); ESES (11)} were included. Etiology was structural (23%) and presumed genetic (77%). All children received intravenous-methylprednisolone pulse followed by oral steroids for eight weeks. Electroencephalography of children with SIEA was partly organized with median SWI of 40% (IQR 35, 42), with anterior-predominant epileptiform abnormalities and less apparent secondary synchronization. Children with ESES had a disorganized EEG background with median SWI of 80% (IQR 66, 95). Both SIEA and ESES groups had a similar neurobehavior profile. Behavior scores improved in 6/8 children with ESES and 5/7 in SIEA post steroids. In both the groups, median SWI improved (to <5% in SIEA, 45% in ESES). Mild improvement in IQ/SQ was also noted {SIEA [Median (IQR): 3 (1.6, 4.3)]; ESES [Median (IQR): 3.8 (2.8, 7)]}. CONCLUSION: The study supports the fact that SWI >50% in the nap EEG is not mandatory for the diagnosis of ESES, thus it should not be a constraint for steroid treatment.

Tumefactive demyelination in pediatrics: An unusual late neurological complication of hematopoietic stem cell transplant.

Immune-mediated demyelination is a rare posttransplant complication. Here, we report an 8.5-year-old boy who developed left hemiparesis, 18 months post matched sibling donor hematopoietic stem cell transplant (HSCT) for relapsed acute myeloid leukemia and was diagnosed to have tumefactive demyelination. The diagnosis was established based on clinical and radiological features. The complete resolution of the lesions with steroids further established the immune-mediated pathophysiology.

Development of a novel outcome prediction score (PEDSS) for pediatric convulsive status epilepticus: A longitudinal observational study.

OBJECTIVE: The objectives of this study were to evaluate ENDIT score and develop a novel outcome prediction score for outcome of pediatric convulsive status epilepticus (CSE) at the hospital and 3 months postdischarge. METHODS: Children and adolescents aged 1 month to 14 years, presenting with CSE to a tertiary care teaching center in North India from January 2017 to March 2019, were screened for enrollment. In-hospital and 3-month postdischarge outcome were defined as poor if Pediatric Cerebral Performance Category Scale (PCPCS) score dropped by ≥2 levels. RESULTS: Overall, 61 patients were enrolled for final analysis after applying exclusion and inclusion criteria. The area under the receiver operating characteristic (ROC) curve for ENDIT score in predicting mortality and differentiating good from poor outcome at the hospital and at 3 months postdischarge was 0.74 (95% confidence interval [CI] = 0.58-0.89), 0.7 (95% CI = 0.57-0.83), and 0.72 (95% CI = 0.6-0.82), respectively. Based on predictors in the present cohort that were significantly different between good and poor outcome cases at the hospital and 3 months postdischarge, a new six-point score named PEDSS (pre-status epilepticus PCPCS, background electroencephalographic abnormalities, drug refractoriness, semiology, and critical sickness) was developed. The area under ROC curves for PEDSS score in predicting mortality and differentiating good from poor outcome at the hospital and at 3 months postdischarge were 0.93 (95% CI = 0.87-0.99), 0.8 (95% CI = 0.7-0.9), and 0.89 (95% CI = 0.8-0.96), respectively. The best cutoff PEDSS scores for predicting mortality and poor outcome at the hospital and at 3 months postdischarge were ≥4, ≥3, and ≥3, respectively. SIGNIFICANCE: The PEDSS score has high predictive accuracy for mortality and differentiating good from poor outcome at the hospital and 3 months postdischarge in pediatric CSE. Future studies should be planned to validate it in various geographical and health care settings and in adults.

Prevalence of smooth muscle dysfunction among children with Duchenne muscular dystrophy.

Smooth muscle dysfunction in Duchenne muscular dystrophy (DMD) has been rarely studied. A cross-sectional study was conducted to estimate the prevalence of smooth muscle dysfunction (vascular, upper gastrointestinal, and bladder smooth muscle) in children with DMD using questionnaires (Pediatric Bleeding Questionnaire, Pediatric Gastroesophageal Symptom Questionnaire, and Dysfunctional Voiding Symptom Score). Investigations included bleeding time estimation, nuclear scintigraphy for gastroesophageal reflux, and uroflowmetry for urodynamic abnormalities. Ninety-nine subjects were included in the study. The prevalence of vascular, upper gastrointestinal, and bladder smooth muscle dysfunction was 27.2%. Mean bleeding time was prolonged by 117.5 seconds. The prevalence of gastroesophageal reflux was 21%. Voided volume/estimated bladder capacity over 15% and abnormal flow curves on uroflowmetry were seen in 18.2% and 9.7% of the subjects, respectively. Our study highlights the need for addressing issues related to smooth muscle dysfunction in the routine clinical care of patients with DMD.

Saposin B-Deficient Metachromatic Leukodystrophy Mimicking Acute Flaccid Paralysis.

Metachromatic leukodystrophy (MLD) is a rare sphingolipid storage disorder caused by arylsulfatase A (ARSA) deficiency, resulting in central and peripheral demyelination. However, an uncommon form of MLD caused by saposin B deficiency is also described (around 10 mutations reported till date). MLD is a systemic disorder affecting the central and peripheral nervous system, gall bladder, and kidneys. Acute flaccid paralysis as the initial clinical presentation is previously known in ARSA-deficient MLD. Hereby, we report a child with acute flaccid paralysis with brain magnetic resonance imaging showing nonspecific periventricular leukodystrophy. He had progressive cognitive decline with gall bladder polyposis. ARSA levels were within normal limits. Leukodystrophy gene panel revealed a homozygous pathogenic deletion (Lys227del variant) in prosaposin (PSAP) gene. Hence, a final diagnosis of saposin B-deficient MLD was established. The index case highlights the importance of clinical and electrophysiological clues in the diagnosis of such atypical presentations of MLD.

Endovascular Management of a Rare Case of Pediatric Vertebral Artery Mycotic Aneurysm: A Case Report.

Pediatric posterior-circulation aneurysms are uncommon, difficult-to-treat lesions associated with significant morbidity and mortality. Infections and trauma are important risk factors in children. Here, we present a 10-year-old boy with a lower respiratory tract infection, rapidly progressive right-neck swelling, and weakness of the right upper limb. Imaging revealed a partially thrombosed right vertebral-artery pseudoaneurysm with multiple cavitory lung lesions. Subsequent laboratory work-up showed underlying primary immunodeficiency disorder (chronic granulomatous disease). The aneurysm was successfully managed by parent-artery occlusion. The child made a complete recovery without neurological sequelae.

Optimal duration for recording EEG in children and adolescents- a prospective interventional study.

PURPOSE: This study aimed to determine the proportion of EEG recordings yielding diagnostic findings leading to a change in diagnosis beyond a 20-minute recording window, striking a balance between diagnostic yield and clinical practicability. METHODS: At a tertiary care teaching hospital in North India, 225 subjects aged 1 month to 18 years undergoing outpatient EEG were enrolled. Patients with epileptic encephalopathies, nonepileptic phenomena, and breakthrough seizures in the last 24 hours were excluded. Two recording protocols were employed: Category A (n=163, awake recording with activation procedures for 15 minutes followed by an attempt at sleep for 60 minutes) and Category B (n=62, sleep recording for 55 minutes followed by 5 minutes of awake recording for younger children and those with impaired cognition). EEGs were prospectively reported at 20, 30, 40, 50, and 60-minute time points, with no retrospective changes allowed. RESULTS: Among abnormal EEGs, the final diagnosis was changed beyond 20 minutes in 38.9% and 20.4% in categories A and B, respectively. A significant change in the final diagnosis among abnormal EEGs beyond 20 minutes was seen in - those who achieved sleep compared to those who didn't (45% versus 19%, p=0.03) in category A, and - focal compared to generalised seizures (Category A: 26.1% versus 8.3%, p=0.01; Category B: 23.8% versus 0%, p=0.02). CONCLUSION: Forty minutes of awake EEGs with/without sleep and 30 minutes of sleep EEGs achieve a final diagnosis in nearly 90%. Prolonging awake records beyond 20 minutes, incorporating sleep, is particularly beneficial in focal epilepsies.

Child Neurology: Allgrove Syndrome: An Intriguing Etiology of Motor Neuron Disease in Children

Motor neuron diseases are a rare group of neurodegenerative disorders with considerable phenotypic heterogeneity and a multitude of etiologies in the pediatric population. In this study, we report 2 unrelated adolescents (a boy and a girl) who presented with 4-6 years of progressive difficulty in walking, thinning of limbs, and gradually progressive darkening of the skin. Examination revealed generalized hyperpigmentation of skin and features suggestive of motor neuron involvement such as tongue atrophy, wasting of distal extremities, and brisk deep tendon reflexes. On detailed exploration for systemic involvement, history of dysphagia, inability to produce tears, and Addisonian crises were evident. An etiologic diagnosis of Allgrove syndrome, which is characterized by a triad of achalasia, alacrimia, and adrenal insufficiency was considered. Next-generation sequencing revealed pathogenic variants in the AAAS gene, confirming the diagnosis. Steroid replacement therapy was initiated along with relevant multidisciplinary referrals. The disease stabilized in the boy and a significant improvement was noted in the girl. These cases highlight the value of non-neurologic cues in navigating the etiologic complexities of motor neuron diseases in children and adolescents. It is imperative for neurologists to develop awareness of the diverse neurologic manifestations associated with Allgrove syndrome because they are often the first to be approached. A multidisciplinary team of experts including neurologists, endocrinologists, gastroenterologists, ophthalmologists, and dermatologists is essential for planning comprehensive care for these patients.

Incident Breakthrough Seizures, Serum Matrix Metalloproteinase-9 and Perfusion Magnetic Resonance Imaging Parameters in a Cohort of Children and Adolescents With Neurocysticercosis: A Longitudinal Observational Study.

BACKGROUND: The current study estimated incident breakthrough seizures, serum matrix metalloproteinase-9 (MMP-9), and perfusion magnetic resonance imaging (MRI) parameters in five- to 18-year-olds with neurocysticercosis (NCC) from colloidal or vesicular through calcified stages over at least 24 months' follow-up. METHODS: Single, colloidal, or vesicular parenchymal NCC cases were treated with albendazole and steroids and followed at a tertiary care north Indian hospital. Serum MMP-9 was estimated in colloidal or vesicular treatment-naive state and in a subset of calcified cases at six-month follow-up. The same subset of calcified cases also underwent perfusion MRI of the brain at six-month follow-up. RESULTS: Among 70 cases, 70% calcified at six-month follow-up. Over a median follow-up of 30 months, the incidence of breakthrough seizures was 48.6% (61.2% in calcified and 19.2% in resolved, P = 0.001; 32.9% early [within six months] and 15.7% late [beyond six months], P = 0.02). Serum MMP-9 levels were higher in colloidal and vesicular compared with calcified stage (242.5 vs 159.8 ng/mL, P = 0.007); however, there was no significant association with breakthrough seizures and/or calcification in follow-up. In a subgroup of calcified cases (n = 31), the median relative cerebral blood volume on perfusion MRI in and around the lesion was lower in those with seizures (n = 12) than in those without (n = 19) (10.7 vs 25.2 mL/100 g, P = 0.05). CONCLUSIONS: In post-treatment colloidal or vesicular NCC, incident breakthrough seizures decrease beyond six months. In calcified NCC with remote breakthrough seizures, significant perilesional hypoperfusion is seen compared with those without seizures.

NDUFV1-Related Mitochondrial Complex-1 Disorders: A Retrospective Case Series and Literature Review.

BACKGROUND: Pathogenic variants in the NDUFV1 gene disrupt mitochondrial complex I, leading to neuroregression with leukoencephalopathy and basal ganglia involvement on neuroimaging. This study aims to provide a concise review on NDUFV1-related disorders while adding the largest cohort from a single center to the existing literature. METHODS: We retrospectively collected genetically proven cases of NDUFV1 pathogenic variants from our center over the last decade and explored reported instances in existing literature. Magnetic resonance imaging (MRI) patterns observed in these patients were split into three types-Leigh (putamen, basal ganglia, thalamus, and brainstem involvement), mitochondrial leukodystrophy (ML) (cerebral white matter involvement with cystic cavitations), and mixed (both). RESULTS: Analysis included 44 children (seven from our center and 37 from literature). The most prevalent comorbidities were hypertonia, ocular abnormalities, feeding issues, and hypotonia at onset. Children with the Leigh-type MRI pattern exhibited significantly higher rates of breathing difficulties, whereas those with a mixed phenotype had a higher prevalence of dystonia. The c.1156C>T variant in exon 8 of the NDUFV1 gene was the most common variant among individuals of Asian ethnicity and is predominantly associated with irritability and dystonia. Seizures and Leigh pattern of MRI of the brain was found to be less commonly associated with this variant. Higher rate of mortality was observed in children with Leigh-type pattern on brain MRI and those who did not receive mitochondrial cocktail. CONCLUSIONS: MRI phenotyping might help predict outcome. Appropriate and timely treatment with mitochondrial cocktail may reduce the probability of death and may positively impact the long-term outcomes, regardless of the genetic variant or age of onset.

Efficacy of daily versus intermittent low glycemic index therapy diet in children with drug-resistant epilepsy: A randomized controlled trial.

INTRODUCTION: The predominant reason for the discontinuation of low glycemic index therapy (LGIT) in children with epilepsy is the dietary restrictions imposed therein. This trial intended to compare the efficacy of daily and intermittent LGIT in children with drug-resistant epilepsy (DRE). METHODS: This study was performed between February 2018 and January 2019 to compare the efficacy of daily and intermittent LGIT in children aged 1-15 years with DRE following 24 weeks of dietary therapy. Compliance, the difficulty faced by caregivers, adverse effects, impact on behaviour, and social quotient in both arms were compared. Children in the intermittent LGIT arm received a liberalized diet for two days every week (Saturday and Sunday), which also allowed medium glycemic index foods. Carbohydrate calories were allowed up to 20% of the total caloric requirement in the liberalized diet, as compared to only 10% in standard LGIT. RESULTS: Out of 132 children randomized (66 in each group), 122 completed 24 weeks follow up. Mean weekly seizure frequency reduction at 24 weeks in the intermittent LGIT group was comparable with that of the daily LGIT group in both intention-to-treat (ITT) and per-protocol analysis (-50.95%± 22.34% vs -47.16%± 23.41%, p=0.36 in ITT and -53.88%±20.54% vs -49.20%±21.87%, p=0.23) in per-protocol analysis for intermittent and daily LGIT group respectively). The proportion with ≥50% reduction in seizure frequency was also comparable between both groups (p=0.73 and 0.56 in ITT and per protocol analysis respectively). The proportion of patients with adverse events and satisfactory compliance rate also had a trend towards favoring intermittent LGIT (p=0.06 and 0.51, respectively), while caregiver difficulty was lower with intermittent LGIT (p=0.001). CONCLUSIONS: Intermittent LGIT is comparable to daily LGIT in terms of seizure frequency reduction after 24 weeks of dietary therapy.

Disseminated phaeohyphomycosis due to Cladophialophora bantiana in an immunocompetent child.

A 3-year-old boy presented with acute headache, vomiting and right focal clonic seizures without history of fever, joint pain or altered sensorium. Neuroimaging showed multifocal contrast enhancing lesions with significant perilesional edema. CECT chest and abdomen showed multiple variable sized nodules in the lungs and hypodense lesion in liver with mesenteric lymphadenopathy. There was persistent eosinophilia with maximum upto 35 %. Liver biopsy and brain biopsy revealed Cladophialophora bantiana. He was treated with IV liposomal amphotericin and voriconazole for 6 weeks with repeat neuroimaging showing more than 50 % resolution of the intracranial lesions. He was transitioned to oral combination of flucytosine and voriconazole. At 14 months follow-up, he remained symptom free with complete radiological resolution of the lesions and no eosinophilia. High suspicion, an aggressive approach in obtaining microbiological diagnosis and timely combination antifungal therapy may give satisfactory outcome without surgery.

Molecular identification of enteroviruses associated with aseptic meningitis in children from India.

We identified and characterized enteroviruses associated with aseptic meningitis in children between April 2009 and March 2010. Enterovirus RNA was detected in 51 (45.5 %) of 112 CSF samples. Molecular typing by RT-PCR and sequencing of a partial VP1 region revealed the predominance of echovirus (ECV) 32 (n = 20), followed by ECV 11 (n = 10), ECV 13 and ECV 14 (n = 5 each), coxsackievirus (CV) B3 and CV B6 (n = 3 each), CV A2, CV A10 and ECV 30 (n = 1 each). Phylogenetic analysis of ECV 32 showed 0 to 4 % sequence divergence among strains of the present study and 20-23 % from the prototype Puerto Rico strain at the nucleotide level. This is the first report of ECV 32 associated with an aseptic meningitis epidemic and identification of seven different enterovirus serotypes (CV A2, CV A10, CV B3, CV B6, ECV 13, ECV 14 and ECV 32) in meningitis cases from India.

Primary Hemophagocytic Lymphohistiocytosis With Prolonged Primary Neurologic Presentation.

Primary hemophagocytic lympho-histiocytosis (HLH) is a hyperinflammatory syndrome with devastating consequences. Multisystem involvement is a hallmark of HLH; however, HLH may rarely present with signs and symptoms isolated to the central nervous system (CNS). Within the brain, HLH can mimic demyelination, chronic infection, or vasculitis, leading to a diagnostic delay of months to years. We describe here a 7-year-old boy who presented with a history of prolonged fever and multiple focal neurologic deficits, which were being treated as CNS tuberculosis at the referring hospital. In view of the relapsing course with multiple areas of hemorrhagic tumefactive lesions on neuroimaging, the diagnosis was revised to acquired demyelination, and he received multiple cycles of immunotherapy. A brain biopsy was inconclusive. Subsequently, 13 months after disease onset, the child presented with features of systemic HLH in the form of fever, pancytopenia, splenomegaly, elevated ferritin, and triglycerides. Primary HLH was suspected, and genetic testing revealed a likely pathologic compound heterozygous variation in the PRF1 gene confirming the diagnosis. We planned a hematopoietic stem cell transplant as definitive therapy, but the child succumbed to an episode of sepsis and aspiration pneumonia. We infer from this case that primary HLH is a great mimicker. A high index of suspicion is required to establish a timely diagnosis. Primary HLH may stay isolated to CNS for months and should be considered in the differential diagnosis of all refractory cases of demyelination.

ASAH1 Variants Causing Spinal Muscular Atrophy Phenotype.

Spinal muscular atrophy with progressive myoclonic epilepsy (SMA-PME) is a rare autosomal recessive disorder due to mutations in the ASAH1 gene. SMA-PME is characterized by progressive muscle weakness from three to seven years of age, drug refractory epilepsy, and variable degree of cognitive decline. Nearly 50 cases have been reported worldwide so far. Here the authors present a case of 9-y-old boy affected by SMA-PME characterized by progressive proximal weakness, and lower motor neuron disease, as proven by muscle biopsy, electro diagnostic studies and whole exome sequencing (WES). WES revealed compound heterozygous missense variant in exon 12 of ASAH1 gene (chr8: g.18059385G>C) and exon 2 of ASAH1 gene (chr8: g.18075542T>C). Patient did not have cognitive decline and epilepsy and EEG record obtained was normal. In addition to reporting a novel variant in the ASAH1 gene causing SMA-PME disease, this paper discusses previous reports and literature of the disease.

Brain Stimulation and Constraint Induced Movement Therapy in Children With Unilateral Cerebral Palsy: A Randomized Controlled Trial.

BACKGROUND: There is a crucial need to devise optimum rehabilitation programs for children with cerebral palsy (CP). OBJECTIVE: This study aimed to assess the feasibility, safety, and efficacy of combining 6-Hz primed, low-frequency, repetitive transcranial magnetic stimulation (rTMS) with modified constraint-induced movement therapy (mCIMT) in improving upper limb function in children with unilateral CP. METHODS: Children aged 5 to 18 years with unilateral CP were randomized (23 in each arm) to receive 10 sessions of mCIMT with real rTMS (intervention arm) or mCIMT with sham rTMS (control arm), on alternate weekdays over 4 weeks. The primary outcome was the difference in mean change in Quality of Upper Extremity Skills Test (QUEST) scores. Secondary outcomes were changes in QUEST domain scores, speed and strength measures, CP quality of life (CP-QOL) scale scores, and safety of rTMS. RESULTS: All 46 children completed the trial except one. At 4 weeks, the mean change in total QUEST scores was significantly higher in the intervention arm as compared to the control arm (11.66 ± 6.97 vs 6.56 ± 4.3, d = 5.1, 95% CI 1.7-8.5, P = .004). Change in "weight bearing" and "protective extension" domain score was significantly higher for children in the intervention arm. These improvements were sustained at 12 weeks (P = .028). CP-QOL scores improved at 12 weeks. No serious adverse events were seen. CONCLUSION: A 6-Hz primed rTMS combined with mCIMT is safe, feasible, and superior to mCIMT alone in improving the upper limb function of children with unilateral CP.
