Association Between Calf Muscle Tone, Plantar Surface Area, and Gross Motor Function in Children with Spastic Diplegic Cerebral Palsy.

Background: Children diagnosed with spastic diplegic Cerebral Palsy (CP) usually demonstrate hypertonicity of the lower limb muscles which affects the normal alignments and weight reception by the feet. These impairments could be correlated to the limitations in gross motor function such as standing and walking abilities. Understanding these relationships can contribute to developing more effective rehabilitation strategies and improving overall motor outcomes for affected children. Objective: The current study was designed to explore the relationship between plantar surface area, weight distribution on the plantar surface, and gross motor function (namely, standing and walking abilities) in spastic diplegic CP children. Methods: Seventy-one spastic diplegic CP children aged 8-14 years joined this cross-sectional study. The Person's correlation coefficient and regression tests were used to assess the correlation between variables, namely, Gross Motor Function (GMFM), Calf Muscle Tone, Plantar surface area (PSA), and Peak pressure on mid and hind feet (PPMF, PPHF, respectively). These variables were assessed using the GMFM-88 scale, Modified Ashworth scale, and foot scan plantar pressure detection system, respectively. Results: The correlation analysis demonstrated a strong to moderate positive correlation between PSA, PPMF, PPHF, and GMFM-D and GMFM-E. Additionally, regression model showed prediction levels equal to 0.791 for the GMFM-D and 0.720 for the GMFM-E categories, respectively. Conclusion: Standing and walking abilities were positively correlated (r ≥.6) with the increased plantar surface area and higher peak pressure on mid and hind feet in spastic diplegic CP. Future longitudinal studies should investigate changes in gross motor function in relation to improvement in plantar surface area and peak pressure values.

Effect of Foot Posture on Limits of Stability in Children With Spastic Diplegic Cerebral Palsy.

Cerebral palsy (CP) is a neurological condition that affects musculoskeletal system causing altered balance control, which is governed by constant adjustments by muscular activity and joint positioning. Since the foot is the platform upon which we stand and balance, it is important to study and characterize foot posture abnormalities in CP to better understand their possible effect on multidirectional limits of stability (MDLS) in standing. Our aim was to find relation between foot posture and MDLS in diplegic children. Thirty diplegics (13 pes-planus and 17 pes-cavus) between the age of 6 to 14, gross motor function classification system (GMFCS) levels I and II, whose parents consented were included in this study. Diplegics unable to stand unsupported for < 2 minutes, undergone lower-limb surgeries in 6 months, having visual impairments were excluded. Foot posture was assessed with arch index, MDLS were measured by GEAMASTER stabilometer. There was significant positive correlation between foot posture and limits of stability. Diplegic children having pes-planus have better MDLS as compared with pes-cavus.

Cerebral palsy in children: A clinical practice review.

Cerebral palsy is a disorder characterized by abnormal tone, posture, and movement. In clinical practice, it is often useful to approach cerebral palsy based on the predominant motor system findings - spastic hemiplegia, spastic diplegia, spastic quadriplegia, extrapyramidal or dyskinetic, and ataxic. The prevalence of cerebral palsy is between 1.5 and 3 per 1,000 live births with higher percentage of cases in low to middle income countries and geographic regions. Pre-term birth and low birthweight are recognized as the most frequent risk factors for cerebral palsy; other risk factors include hypoxic-ischemic encephalopathy, maternal infections, and multiple gestation. In most cases of cerebral palsy, the initial injury to the brain occurs during early fetal brain development. Intracerebral hemorrhage and periventricular leukomalacia are the main pathologic findings found in preterm infants who develop spastic cerebral palsy. The diagnosis of cerebral palsy is primarily based on clinical findings. Early recognition of infants at risk for cerebral palsy as well as those with cerebral palsy is possible based on a combination of clinical history, use of standardized neuromotor assessment and findings on magnetic resonance imaging; however, in clinical practice, cerebral palsy is more reliably diagnosed by 2 years of age. Magnetic resonance imaging scan is indicated to delineate the extent of brain lesions and to identify congenital brain malformations. Genetic testing and tests for inborn errors of metabolism are indicated to identify specific disorders, especially treatable disorders. Because cerebral palsy is associated with multiple associated and secondary medical conditions, its management requires a sustained and consistent collaboration among multiple disciplines and specialties. With appropriate support, most children with cerebral palsy grow up to be adults with good functional abilities.

Movement disorder phenotype in CTNNB1-syndrome: A complex but recognizable phenomenology.

INTRODUCTION: CTNNB1 gene loss-of-function variants cause Neurodevelopmental disorder with spastic diplegia and visual defects (NEDSDV, OMIM 615075). Although motor impairment represents a core feature of this condition, the motor phenotype remains poorly described. We systematically assessed a cohort of 14 patients with disease-causing CTNNB1 variants to better characterize the movement disorder phenotype. METHODS: patients were enrolled at Bambino Gesù Children's Hospital in Rome, Italy, between January 2019 and February 2024. 14 participants were included and underwent extensive genetic and neurologic examination. Clinical features, neuroimaging and neurophysiological investigations were retrospectively analyzed from medical charts and video recordings. RESULTS: 13 out of 14 patients showed motor disorders (one only showing mild coordination difficulties). 12 presented abnormal gait (11 patients with broad-based gait, one with narrow-based in-toeing gait, one with broad-based gait with unilateral intoeing). One did not achieve walking ability. 13 patients presented progressive lower limbs hypertonia without overt pyramidal signs. Five patients reported exaggerated startle, three developed upper body (prominently cervical) dystonia in the second decade, with or without bradykinesia (2/13). Treatment efficacy was variable: botulinum toxin was (at least partially) effective in 5/6, levodopa in 1 of 4 treated patients. CONCLUSIONS: CTNNB1-syndrome is associated with a peculiar, but recognizable movement disorder phenotype, encompassing complex gait disorders with progressive lower limb hypertonia, exaggerated startle, and possible occurrence in the second decade of life of upper body dystonia with or without bradykinesia.

Efficacy of neuromuscular electrical stimulation and interrupted serial casting in children with spastic diplegia.

Objectives: This research was aimed at comparing the effects of neuromuscular electrical stimulation (NMES) combined with interrupted serial casting (SC) versus SC alone on various aspects of lower limb function in children with diplegic cerebral palsy. SC is a clinical technique used to increase passive range of motion (ROM), decrease hypertonicity, and improve walking in children with cerebral palsy (CP). Methods: This randomized comparative trial involved 33 children with diplegic CP, who were randomly assigned to group A or group B at recruitment. Group A received SC along with a customized physical therapy program, whereas group B received the same interventions as group A along with NMES applied through cast windows during casting. Evaluations were based on ROM, the Modified Tardieu Scale, handheld dynamometer measurements, and the Observational Gait Scale. Assessments were conducted before and after 8 weeks of intervention. Results: Both groups exhibited significant improvements in dorsiflexion ROM, popliteal angle, gastrocnemius dynamic spasticity, and hamstring dynamic spasticity after the intervention (P = 0.0001 for all). However, significant differences (P < 0.05) in dorsiflexor strength, knee extensor strength, and observational gait scale score were observed between groups after the intervention, favoring group B. Conclusions: The use of NMES during SC may help overcome the substantial decrease in strength resulting from casting, thus achieving less reduction of tone, improving ROM without significantly decreasing strength, and attaining greater improvements in gait function.

Epidemiological predictors of quality of life and the role of early markers in children with cerebral palsy: A multi-centric cross-sectional study.

BACKGROUND: More than 100 million children in the world have at least one type of disability. Among disabled children, approximately 25% of chronic disabilities are of neurological origin. Cerebral Palsy is the leading cause of chronic disability in children, making them not only physically and mentally handicapped but also socially aloof. METHODS: This study was conducted among 200 eligible participants from three centers with Child Guidance or Cerebral Palsy clinics in the outpatient department. All the participants were included in the analysis of the epidemiological profile and the role of early markers. Of these, 70 participants were assessed for quality of life according to the age criteria of a pre-tested Cerebral Palsy Quality of Life questionnaire (CP-QOL). RESULTS: Mean ± S.D. age in years was 3.7 ± 2.8. Birth history included 182 (39%) neonatal etiopathology, followed by 173 (38%) perinatal, and 106 (23%) antenatal causes. Mean ± S.D. birth weight was 2.3 ± 1.2 kg. The positive predictors of various domains of Quality of Life were an absence of any associated sensory, neurological, communication, or psychological disorder or disability. While, the negative predictors were decreasing functional capacity, involvement of number of limbs in increasing order, high therapeutic requirements, and dependency. CONCLUSION: The association between early diagnosis of cerebral palsy and improved functional capacity, involvement of a lesser number of limbs, better quality of life, and absence of associated disabilities is established from the findings of our study.

Clinical and serological insights into paraneoplastic brachial amyotrophic diplegia.

BACKGROUND: Brachial amyotrophic diplegia (BAD) is typically linked to a neurodegenerative etiology such as amyotrophic lateral sclerosis (ALS). Clinical and serological characterizations of paraneoplastic neurologic syndromes resembling BAD are limited. METHODS: A retrospective chart review of patients with BAD-like presentations was conducted. Clinical/paraclinical features of paraneoplastic BAD and neurodegenerative BAD cases were compared. RESULTS: Between 2017 and 2023, 13 cases of BAD were identified, of these 10 were neurodegenerative BAD (ALS variant), and 3 cases associated with paraneoplastic autoimmunity. An additional paraneoplastic BAD case diagnosed in 2005 was included. LUZP4-IgG was detected in all four paraneoplastic cases, with coexisting KLHL11-IgG in three cases and ANNA1 (anti-Hu)-IgG in one case. Out of the four paraneoplastic cases, two patients had seminoma, while the remaining two had limited cancer investigation. Three patients exhibited bi-brachial weakness as the initial symptom before the onset of brainstem symptoms or seizures. Compared to BAD patients with a neurodegenerative etiology, a higher proportion of paraneoplastic cases had ataxia (75% vs 0%, p = 0.011). Other clinical features only detected in the paraneoplastic BAD group were vertigo (n = 2), hearing loss (n = 2) and ophthalmoplegia (n = 2). Electrodiagnostic studies in these patients revealed cervical myotome involvement, supportive of motor neuronopathy. All paraneoplastic cases but none of the neurodegenerative BAD cases exhibited inflammatory cerebrospinal fluid (CSF) findings (lymphocytic pleocytosis and/or supernumerary oligoclonal bands; p = 0.067). Despite the administration of immunotherapy and/or cancer treatment, none of the paraneoplastic patients reported clinical improvement. DISCUSSION: BAD or bi-brachial neurogenic weakness is a rare phenotypic presentation associated with paraneoplastic autoimmunity. Co-existing features of brainstem dysfunction or cerebellar ataxia should prompt further paraneoplastic evaluation. Common serological and cancer associations among these cases include LUZP4-IgG and KLHL11-IgG, along with testicular germ cell tumors, respectively.

Risk Factors for Term-Born Spastic Diplegic Cerebral Palsy: A Case-Control Study.

BACKGROUND: To identify if a predetermined set of potential risk factors are associated with spastic diplegic cerebral palsy (SDCP) in term-born children. METHODS: This is a case-control study with cases (n = 134) extracted from the Canadian Cerebral Palsy Registry (CCPR) and controls (n = 1950) from the Alberta Pregnancy Outcomes and Nutrition (APrON) study. Our primary variable was the SDCP phenotype in term-born children. Possible risk factors were selected a priori and include extreme maternal age (<19 or >35 years), pregnancy complications, maternal disease, substance use, perinatal infection, mode of delivery, perinatal adversity (i.e., neonatal encephalopathy presumably on the basis of intrapartum hypoxia-ischemia), sex, and birth weight. Multivariable analyses were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Multivariable analysis revealed associations between term-born SDCP and pregnancy complications (OR = 4.73; 95% CI = 1.91 to 10.56), maternal disease (OR = 2.52; 95% CI = 1.57 to 3.93), substance use (OR = 3.11; 95% CI = 2.10 to 4.55), perinatal infection (OR = 2.72; 95% CI 1.32 to 5.10), Caesarean section (OR = 2.35; 95% CI = 1.62 to 3.40), and perinatal adversity (OR = 2.91; 95% CI = 1.94 to 4.50). Multiple regression analysis revealed associations between SDCP and pregnancy complications (OR = 3.28; 95% CI 1.20 to 8.15), maternal disease (OR = 2.52; 95% CI 1.50 to 4.12), substance use (OR = 3.59; 95% CI 2.37 to 5.40), perinatal infection (OR = 3.78, 95% CI 1.71 to 7.72), Caesarean section (OR = 2.72; 95% CI 1.82 to 4.03), and perinatal adversity (OR = 4.16; 95% CI 2.67 to 6.70). INTERPRETATION: Antenatal (pregnancy complications, maternal disease, substance use) and perinatal (infections, Caesarean section, and perinatal adversity) risk factors are associated with an increased risk of SDCP in term-born children, suggesting variable interactions between risk factors to provide a clinicopathologic framework that is different from SDCP observed in preterm-born children.

Tratamiento de la contractura en flexión de rodilla en parálisis cerebral / Treatment for knee flexion contracture in cerebral palsy

La extensión completa de la rodilla es esencial para la marcha. Los pacientes con parálisis cerebral infantil con frecuencia pueden tener déficit de extensión de distinta magnitud, lo que compromete la marcha e incluso la bipedestación. El tratamiento de la contractura en flexión de rodilla parte por tratar la espasticidad de los músculos comprometidos y con fisioterapia. Cuando el flexo es estructurado, el tratamiento es quirúrgico mediante distintas técnicas, dependiendo de la magnitud de la contractura y de la edad del paciente. Las técnicas sobre partes blandas incluyen alargamientos funcionales de isquiotibiales y transferencias musculares. Cuando la contractura es capsular, es preferible realizar cirugía ósea, la cual extiende el fémur proximal, ya sea en forma progresiva, mediante fisiodesis anterior en pacientes pediátricos, o en forma aguda, mediante osteotomía extensora del fémur distal. Con frecuencia existe una patela alta, la cual hay que corregir en el mismo acto quirúrgico para mantener la eficiencia del aparato extensor

Full knee extension is essential for gait. Patients with cerebral palsy frequently have extension deficits of different magnitudes, which compromise walking and even standing up. The treatment of knee flexion contracture begins by addressing the spasticity of the involved muscles and includes physical therapy. For structured extension deficits, the treatment is surgical, using different techniques depending on the magnitude of the contracture and the patient's age. Soft tissue techniques include functional hamstring lengthening and muscle transfers. For capsular contracture, bone surgery is preferable and extends the proximal femur either progressively, through anterior physiodesis in pediatric patients, or acutely, by extensor distal femoral osteotomy. A high patella is common and requires correction during the same surgical procedure to maintain the efficiency of the extensor apparatus

Therapeutic effect of the new multilevel brace orthosis on cerebral palsy gait: a case report.

Background: Infantile spastic bilateral cerebral palsy (CP) is the most common form of CP. Diplegia (with ambulatory ability) is mostly a chronic condition that impairs the ability to walk. Standard orthotic management includes hip-knee-ankle-foot orthosis (HKAFO) as a pri-mary conservative treatment option to contrast spasticity and stabilise gait through partial immobilisation of the body structure. Multilevel brace orthosis (MLB) (Registered Trademark) is a specific type of light HKAFO designed to improve functional alignment and dynamic gait stability without limb immobilisation. Aim of the case report is to verify the effects of the MLB on the diplegic gait cycle. Case: A child with a bilateral spastic gait due to CP diplegia is described. Gait analyses were performed to investigate the therapeutic effects of the MLB on walking. Discussion: The MLB improved the gross motor function measure of walking and gait temporal parameters (velocity), compared with barefoot condition. During the swing phase, we observed a reduction in plantar and knee flexion, and the orthosis increased the width and length of the step. Conclusion: Use of this specific type of HKAFO in children with diplegia improved gait symmetry and stability.

Efficacy of Lower Limb Orthoses in the Rehabilitation of Children Affected by Cerebral Palsy: A Systematic Review.

Lower limb orthoses are frequently used in children suffering from cerebral palsy (CP) alongside rehabilitation. The aim of this study was to analyze the effectiveness of ankle-foot orthosis (AFO) and knee-ankle-foot orthosis (KAFO) in walking, balance maintenance, spasticity, and quality of life improvement during rehabilitation in children affected by CP. The hypothesis was that the use of orthoses could improve the parameters compared to non-use. A systematic review was conducted in the main databases, including English language RCTs published about the use of AFO and KAFO in combination or not with rehabilitation methods in children affected by CP and studies mentioning walking, balance, muscle length, and quality of life as outcomes. From an initial number of 1484 results, a final number of 11 RCTs were included, comprising a total number of 442 participants and showing an overall high risk of bias in 10 studies and some concerns in one study. Six studies investigated the domain of walking, four studies investigated the domain of balance, and two studies investigated how KAFO and AFO orthoses could improve and prevent muscle contractures. Using highly heterogeneous study designs, different kinds of orthoses and different assessment tools were used. Further studies conducted with higher methodological quality are needed to establish whether AFO and KAFO are useful or not in combination with rehabilitation in improving the investigated domains.

Selective dorsal rhizotomy using a 3D high definition exoscope.

Selective dorsal rhizotomy (SDR) is an established neurosurgical technique for children with spastic diplegia secondary to cerebral palsy. Meticulous intraoperative testing of individual nerve roots with electromyography in tandem with the on-site neurorehabilitation team is recommended for good clinical outcomes. The standard approach requires the neurosurgeons to spend extended time under the traditional operating microscope. In this video, the authors describe the use of a 3D exoscope system for SDR. Overall, the 3D exoscope improves ergonomics and reduces musculoskeletal fatigue for the operating neurosurgeons. Furthermore, it provides excellent visualization of important structures, allowing safe and efficient completion of the procedure.

Bibrachial amyotrophy as a rare manifestation of intraspinal fluid collection: a case report and systematic review.

INTRODUCTION: Intraspinal cerebrospinal fluid (CSF) collection has been reported as a rare cause of lower motor neuron (LMN) disorder. We report a case of bibrachial diplegia associated with intraspinal CSF collection and perform a systematic literature review. PATIENT AND METHODS: A 52-year-old man developed a bibrachial amyotrophy over 6 years, confirmed by the presence of cervical subacute neurogenic changes at electromyography (EMG). Brain magnetic resonance imaging (MRI) revealed cerebral siderosis, while spine MRI showed a ventral longitudinal intraspinal fluid collection (VLISFC) from C2 to L2. No CSF leakage was localized at myelography; a conservative treatment was chosen. We searched for all published cases until 30th April 2023 and extrapolated data of 44 patients reported in 27 publications. RESULTS: We observed a male predominance, a younger disease onset compared to amyotrophic lateral sclerosis, and a quite long disease duration, highlighting a slow disease progression. LMN signs were more frequently bilateral, mostly involving C5-C6 myotomes. Around 61% of patients presented additional symptoms, but only three referred to a history of headache. Accordingly, CSF opening pressure was mostly normal. Spinal MRI revealed the presence of VLISFC and in some cases myelomalacia. EMG patterns displayed both chronic and subacute neurogenic change in the cervical region. The disease course mainly depended on the treatment choice, which was mostly represented by a surgical approach when a specific dural defect was detected by imaging. CONCLUSION: Bibrachial diplegia due to VLISFC can be a treatable cause of focal amyotrophy and presents some clinical and radiological "red flags" which cannot be missed by a clinical neurologist.

Trunk postural reactions to the force perturbation intensity and frequency during sitting astride in children with cerebral palsy.

The purpose of this study was to examine kinematic and neuromuscular responses of the head and body to pelvis perturbations with different intensities and frequencies during sitting astride in children with CP. Sixteen children with spastic CP (mean age 7.4 ± 2.4 years old) were recruited in this study. A custom designed cable-driven robotic horse was used to apply controlled force perturbations to the pelvis during sitting astride. Each participant was tested in four force intensity conditions (i.e., 10%, 15%, 20%, and 25% of body weight (BW), frequency = 1 Hz), and six force frequency conditions (i.e., 0.5 Hz, 1 Hz, 1.5 Hz, 2 Hz, 2.5 Hz, and 3 Hz, intensity = 20% of BW). Each testing session lasted for one minute with a one-minute rest break inserted between two sessions. Kinematic data of the head, trunk, and legs were recorded using wearable sensors, and EMG signals of neck, trunk, and leg muscles were recorded. Children with CP showed direction-specific trunk and neck muscle activity in response to the pelvis perturbations during sitting astride. Greater EMG activities of trunk and neck muscles were observed for the greater intensities of force perturbations (P < .05). Participants also showed enhanced activation of antagonistic muscles rather than direction-specific trunk and neck muscle activities for the conditions of higher frequency perturbations (P < .05). Children with CP may modulate trunk and neck muscle activities in response to greater changes in intensity of pelvis perturbation during sitting astride. Perturbations with too high frequency may be less effective in inducing direction-specific trunk and neck muscle activities.

Effects of lower limb exoskeleton robot gait training on balance function in children with spastic diplegia / 中国康复医学杂志

Objective:To investigate the effect of lower limb exoskeleton robots on balance function in children with spas-tic diplegia. Method:Twenty children with spastic diplegia who were admitted to the Department of Rehabilitation of the Children's Hospital of Zhejiang University School of Medicine from July 2022 to December 2022 were includ-ed in the treatment group.The other 20 children matched with age,gender and functional status were includ-ed in the control group.Both groups were given conventional rehabilitation training(exercise therapy,suspen-sion training,isokinetic muscle strength training),and the treatment group were received the 30-min lower limb exoskeleton robot training 5 times a week for 8 weeks.Before and after treatment,the two groups were tested with surface electromyography(sEMG)data,dynamic balance response displacement,static balance score,and Pediatric Balance Scale(PBS). Result:Before treatment,there was no statistically significant difference(P＞0.05)in sEMG values(gluteus maximus,gluteus medius,quadriceps femoris and tibialis anterior muscle),dynamic balance reaction displace-ment,static balance score,and PBS score between the two groups.There were significant improvements in the scores of these measurements(P＜0.05)in both group before and after treatment.Compared with the con-trol group,there were statistically significant differences in sEMG values(gluteus maximus P=0.021;gluteus medius P=0.016;quadriceps femoris P=0.004),dynamic balance reaction displacement(anterior P=0.014;left P=0.003;right P=0.003),static balance score(P=0.005),and PBS score(P=0.004)in the treatment group af-ter treatment. Conclusion:Lower limb exoskeleton robot gait training combined with conventional rehabilitation treatment can effectively improve the balance function of cerebral palsy children with spastic diplegia.

Engaging the Lower Extremity via Active Therapy Early (ELEVATE) Is Feasible and May Improve Gross Motor Function in Children with Spastic Bilateral Cerebral Palsy: A Case Series.

Purpose: The feasibility of ELEVATE with respect to adherence and preliminary efficacy was determined for children with spastic bilateral cerebral palsy (CP) from encephalopathy of prematurity. Methods: A case series was used. Participants were randomized to receive ELEVATE immediately or delay the intervention by 3 months before receiving the intervention. The outcomes included feasibility measures of (1) number of children recruited, (2) percentage of sessions attended, (3) stride counts during the intervention, and preliminary efficacy measures of change over the intervention period in (4) Gross Motor Function Measure-66 (GMFM-66), and (5) kinematics and weight-bearing during treadmill walking. Results: Four boys under 3 years of age participated. All participants tolerated 60-minute intervention sessions four times/week for 12 weeks, and attended 75%-94% (min-max) of the targeted sessions. The median step count per session ranged from 833 to 2484 steps (min-max) during the final week of training. Participants showed an increase in GMFM-66 score of 2.4-7.5 points (min-max) over the 3-month intervention phase, as compared to a decrease of 1.7 for one participant and an increase of 1.3 for another over the delay period. Three participants demonstrated small improvements in their gait with the intervention. Conclusions: Engaging young children with bilateral CP in intensive rehabilitation targeting gross motor function was feasible and demonstrated preliminary efficacy. The results have guided the design of a larger clinical trial to assess efficacy of early, active interventions for children with spastic bilateral CP.

Objectif: les chercheurs ont déterminé la faisabilité d'ELEVATE en matière d'adhésion et d'efficacité préliminaire chez des enfants ayant une paralysie cérébrale spastique bilatérale (PC) causée par une encéphalopathie de la prématurité. Méthodologie: série de cas. Les participants ont été choisis au hasard entre l'utilisation immédiate d'ELEVATE ou son report de trois mois. Les résultats incluaient des mesures de fiabilité, soit 1) le nombre d'enfants recrutés, 2) le pourcentage de séances suivies, 3) le compte des foulées pendant l'intervention et les mesures d'efficacité préliminaire pendant la période de l'intervention sur le plan de 4) la mesure de la fonction motrice globale 66 (GMFM-66) et de 5) la cinématique et la mise en charge pendant la marche sur tapis roulant. Résultats: quatre garçons de moins de trois ans ont participé. Tous ont toléré des séances d'intervention de 60 minutes quatre fois par semaine pendant 12 semaines et ont assisté à 75 % à 94 % (minimum-maximum) des séances ciblées. Le compte médian de foulées par séance se situait entre 833 et 2 484 foulées (minimum­maximum) lors de la dernière semaine d'entraînement. Les participants ont présenté une augmentation de 2,4 à 7,5 points (minimum-maximum) au score du GMFM-66 pendant les trois mois de la phase d'intervention, par rapport à une diminution de 1,7 point chez un participant et à une augmentation de 1,3 point chez un autre pendant la période de report. Trois participants ont démonté de légères améliorations de leur démarche grâce à l'intervention. Conclusions: il est faisable de faire participer des jeunes enfants ayant une PC bilatérale à une réadaptation intensive visant la fonction motrice globale, et cette intervention a une efficacité préliminaire démontrée. Les résultats ont entraîné la conception d'une étude clinique plus vaste pour évaluer l'efficacité d'interventions précoces actives chez les enfants ayant une PC bilatérale spastique.

Symptomatic spinal arachnoid cyst with spastic diplegia secondary to cerebral palsy: illustrative case.

BACKGROUND: Selective dorsal rhizotomy (SDR) can improve the spastic gait of carefully selected patients with cerebral palsy. Spinal arachnoid cysts are a rare pathology that can also cause spastic gait secondary to spinal cord compression. OBSERVATIONS: The authors present an interesting case of a child with cerebral palsy and spastic diplegia. He was evaluated by a multidisciplinary team and determined to be a good candidate for SDR. Preoperative evaluation included magnetic resonance imaging (MRI) of the spine, which identified an arachnoid cyst causing spinal cord compression. The cyst was surgically fenestrated, which provided some gait improvement. After recovering from cyst fenestration surgery, the patient underwent SDR providing further gait improvement. LESSONS: SDR can be beneficial for some patients with spastic diplegia. Most guidelines do not include spinal MRI in the preoperative evaluation for SDR. However, spinal MRI can be beneficial for surgical planning by localizing the level of the conus. It may also identify additional spinal pathology that is contributing to the patient's spasticity. In rare cases, such as this one, patients may benefit from staged surgery to address structural causes of spastic gait prior to proceeding with SDR.

Crouch Gait in Cerebral Palsy: Current Concepts Review.

Background and Objective: Crouch gait is the most common pathological gait pattern in cerebral palsy and is commonly seen in patients with spastic diplegia. It is characterized by excessive knee flexion throughout the stance phase of gait cycle. The aim of this review is to discuss the current literature about CG for a more comprehensive understanding. Methods: A literature review about various aspects of crouch gait in cerebral palsy was undertaken. This included its etiology and pathophysiology, biomechanics in crouch gait, natural history of untreated crouch gait, clinical and radiological evaluation and different modalities of available treatment. Results: The etiology is multifactorial and the pathophysiology is poorly understood. This makes its management challenging, thereby leading to a variety of available treatment modalities. Inadvertent lengthening of muscle-tendon units is an important cause and can be avoided. A meticulous clinical and radiological evaluation of patients, supplemented by observational and instrumented gait analysis is mandatory in choosing correct treatment modality and improving the treatment outcome. Younger children can be managed satisfactorily by various non-operative methods and spasticity reduction measures. However, crouch gait in cerebral palsy has a progressive natural history and surgical interventions are needed frequently. The current literature supports combination of various soft tissue and bony procedures as a part of single event multilevel surgery. Growth modulation in the form of anterior distal femur hemiepiphysiodesis for correction of fixed flexion deformity of knee has shown encouraging results and can be an alternative in younger children with sufficient growth remaining. Conclusions: In spite of extensive research in this field, the current understanding about crouch gait has many knowledge gaps. Further studies about the etiopathogenesis and biomechanics of crouch using instrumented gait analysis are suggested. Similarly, future research should focus on the long term outcomes of different treatment modalities through comparative trials.

Effectiveness of Neurodevelopmental Treatment and Sensory Integration Therapy on Gross Motor Function, Balance and Gait Parameters in Children With Spastic Diplegia.

Background Spastic diplegic cerebral palsy is the type that is most frequently seen in clinical settings. Spastic diplegic children have trouble maintaining their balance, gait, and gross motor function. This study investigated the effects of the Neurodevelopmental Technique (NDT) and Sensory Integration Technique (SIT) on balance, gross motor function, and gait characteristics in children with spastic diplegia. Method The study's participants were 8 to 12 years old, with spastic diplegia, categorized into stages I to III of the Gross Motor Function Classification System. While individuals in group B underwent sensory integration therapy, group A's subjects received NDT for 45 minutes. Both groups received traditional physiotherapy for 15 minutes. The protocol was given for five days a week, continuously for four weeks. All 40 subjects underwent pre- and post-treatment assessments using the Gross Motor Function Measure-88 (GMFM-88), Paediatric Balance Scale, Gait Parameters, and Gross Motor Function Classification System. Results The trial involved 40 children, divided into two groups of 20 each. Statistical analysis demonstrated a substantial improvement in group B post-intervention (P>0.0001). The study's findings were drawn using the Chi-Square test, paired and unpaired t-tests, and SPSS Statistics for Windows, version 27.0 (IBM Corp., Armonk, USA).A p<0.05 and the GraphPad Prism version 7.0 (GraphPad Software, Boston, USA) were used. A total of 40 children completed the entire duration of treatment for a month. 20 subjects participated in group A (age range 8-12 years; mean age 10.3 years) and 20 subjects in group B (age range 8-12 years; mean age 10.25 years). The GMFM-88, which assesses motor function, reveals that the between-group comparison indicates a substantial difference of 7.95 (6.04-9.86) in favor of Group B, with a p-value of 0.0001, signifying statistical significance. Similarly, the Pediatric Balance Scale (PBS) outcomes significantly enhanced in both groups post-intervention. The comparison between groups yields a difference of 1.85 (1.11-2.59) in favor of Group B, with a p-value of 0.0001.
