Self-reported gait unsteadiness in mildly impaired neurological patients: an objective assessment through statistical gait analysis
Background Self-reported gait unsteadiness is often a problem in neurological patients without any clinical evidence of ataxia, because it leads to reduced activity and limitations in function. However, in the literature there are only a few papers that address this disorder. The aim of this study is to identify objectively subclinical abnormal gait strategies in these patients. Methods Eleven patients affected by self-reported unsteadiness during gait (4 TBI and 7 MS) and ten healthy subjects underwent gait analysis while walking back and forth on a 15-m long corridor. Time-distance parameters, ankle sagittal motion, and muscular activity during gait were acquired by a wearable gait analysis system (Step32, DemItalia, Italy) on a high number of successive strides in the same walk and statistically processed. Both self-selected gait speed and high speed were tested under relatively unconstrained conditions. Non-parametric statistical analysis (Mann-Whitney, Wilcoxon tests) was carried out on the means of the data of the two examined groups. Results The main findings, with data adjusted for velocity of progression, show that increased double support and reduced velocity of progression are the main parameters to discriminate patients with self-reported unsteadiness from healthy controls. Muscular intervals of activation showed a significant increase in the activity duration of the Rectus Femoris and Tibialis Anterior in patients with respect to the control group at high speed. Conclusions Patients with a subjective sensation of instability, not clinically documented, walk with altered strategies, especially at high gait speed. This is thought to depend on the mechanisms of postural control and coordination. The gait anomalies detected might explain the symptoms reported by the patients and allow for a more focused treatment design. The wearable gait analysis system used for long distance statistical walking assessment was able to detect subtle differences in functional performance monitoring, otherwise not detectable by common clinical examination
Valutazione clinica e gait analysis in bambini diplegici. Studio su soggetti con deambulazione autonoma sottoposti a trattamento con tossina botulinica o tossina associata a gessi inibitori
Questo studio pilota confronta i risultati clinici e strumentali in due gruppi di bambini affetti da diplegia spastica lieve che presentavano equinismo dinamico, sottoposti rispettivamente al trattamento con tossina botulinica (BTX-A) e a trattamento associato con tossina botulinica e gessi inibitori.
Il protocollo di studio comprendeva la valutazione della spasticit\ue0 mediante scala di Ashworth, la valutazione del cammino e delle prestazioni motorie mediante la scala Gross motor function measure (GMFM), l\u2019escursione articolare dell\u2019articolazione tibiotarsica e l\u2019analisi strumentale del cammino, con controlli ripetuti prima del trattamento, dopo un mese, dopo quattro mesi, fino a un follow-up di un anno
Early multilevel minimally-invasive approach (EMMA) nel trattamento della paralisi cerebrale infantile : Casi in neuroriabilitazione
Tendon collagen turnover-related genes in cerebral palsy
Children with infantile autism sometimes show hyperesthesia or hypoesthesia to touch, pain, and/or temperature. To clarify the pathophysiology, we examined short-latency somatosensory evoked potentials (S-SEPs), elicited by median nerve stimulation, in 24 children with infantile autism (17 males, seven females; age range 2y 2mo-9y; mean age 4y 2mo [SD 1y 7mo]). We also evaluated relationships between S-SEP findings and clinical manifestations. Of the 24 children, 10 showed abnormal S-SEPs as follows: prolonged peak latency of N20 (n=2), extended interpeak latency of P13/14-N20 (n=7), appearance of a giant SEP (n=1), and a more than twofold right hemispheric peak-to-peak amplitude predominance of N20-P25 (n=5). In addition, a peak-to-peak amplitude of N20-P25 elicited by left median nerve stimuli was significantly higher than that obtained with right median nerve stimuli, which indicated right hemispheric hyperactivity relative to the left (p=0.008). Infantile autism is frequently associated with somatosensory abnormalities and right hemispheric hyperactivity relative to the left, especially in the primary somatosensory area. This is believed to contribute to the pathophysiology of infantile autism, especially the idiopathic form
Le centrage des hanches au moyen de sigès moulés : Études et résultats
Background: Musculo-skeletal disorders and hip deformity play a key role on future development of motor and adaptive functions in children with cerebral palsy (CP). Lateral migration of the femoral head increases on average of 7.7% per year and may progress to hip dislocation. Conservative preservation of muscle length and balance may prevent or reduce femoral head migration and acetabular dysplasia. A prospective comparative non randomized study was conducted to determine the effect of a sige moul\ue9 postural management, in association with a physiotherapy program, on the progression of hip displacement in children with CP. Thirty-five patients with bilateral CP and so-called hip at risk (migration percentage [MP] of over 10% but less than 40%) were included into the study and evaluated by neurofunctional assessment, Gross Motor Function Classification System (GMFCS), Tardieu scale and radiological measurements (MP by Reimers). Eighteen children were treated with therapeutic education and postural management 4 hours a day, and 17 children (control group) were treated with NDT alone. Results: A significant difference was found between MP values of case group and control group after 1 year (T1) and 2 years of treatment (T2) (p = 0,001). The rate of hip displacement was reduced by 5 % in the treatment group after the first year and by 7 % at second follow-up. Conclusion: Our data show a progressive reduction of MP values measured in the treated group confirming the significant benefit from combined non-surgical approach. The study supports the evidence that conservative management of hip deformity can be successful if implemented before the development of hip dysplasia
"Postural Management" to prevent hip dislocation in children with cerebral palsy
Muscolo-skeletal disorders and hip deformity play a key role on future development of motor and adaptive functions in children with cerebral palsy (CP). Lateral migration of the femoral head increases on average 7.7% per year and may progress in association with acetabular dysplasia to hip dislocation. Conservative preservation of muscle length and balance may prevent or reduce femoral head migration and acetabular dysplasia. Equipment for position lying, sitting, and standing is an established method of maintaining muscle length and joint range. French approach (Le M\ue9tayer et al) include the use of customised plaster cast orthoses, for sitting and standing positions, called si\ue8ge moul\ue9 and goutti\ue8re, tailor-made according to the child's muscolo-skeletal characteristics and motor abilities. At our department, hips with clinical and radiological evidence of displacement unresponsive to pharmacological and surgical treatment were treated with postural management. The two cases we show in this paper underwent a physiotherapy programme (neurodevelopment treatment ) twice a week and a seated postural programme 5 hours a day with the si\ue8ge moul\ue9. Hip radiographs were measured with the migration percentage (MP) described by Reimers. The follow-up measurements showed a progressive reduction of MP values of the hip treated, confirming the significant benefit from the combined non surgical approach. The study supports the evidence that conservative management of hip deformity with si\ue8ge moul\ue9 can be successful if implemented before the development of hip dysplasia
