RESUMO

OBJECTIVE: Investigate the effects of botulinum toxin type A (BoNT-A) combined with physical therapy on functional capacity in children with spastic cerebral palsy (CP). METHODS: Twenty-four children with spastic CP were treated with either BoNT-A and physical therapy or physical therapy alone. RESULTS: Significant differences (p < 0.05) were found after 30 days of treatment for the Berg Scale, Timed Up and Go (TUG) test, Ashworth Scale and Pediatric Evaluation of Disability Inventory (PEDI) and after three months for the Berg Scale, TUG test and PEDI. No significant differences (p > 0.05) were found in the control group. DISCUSSION: BoNT-A combined with physical therapy leads to significant improvements in spasticity and functionality in children with CP within a period of three months from the onset of treatment.

RESUMO

OBJECTIVE: The purpose of this study was to generate data for conduction of a power analysis to investigate short-term effects of visceral manipulation associated with conventional physical therapy on pain intensity, lumbar mobility, and functionality of people with chronic low back pain and visceral dysfunctions. METHODS: This was a double-blinded, randomized, controlled, clinical trial preliminary study. A blinded evaluation was conducted involving 20 people with chronic low back pain with visceral dysfunction. Pain perception, lumbar mobility, and functionality were assessed in 3 moments: evaluation 1 (1 week before the intervention), evaluation 2 (immediately after the last intervention), and evaluation 3 (1 week after the last intervention). The protocol consisted of 50-minute session of conventional physical therapy and visceral manipulation. The participants were randomly allocated to 2 groups: 10 for the experimental group (conventional physical therapy and visceral manipulation) and 10 for the control group (conventional physical therapy and placebo visceral manipulation). RESULTS: Significant reductions were found in the experimental group for lumbar mobility and specific functionality in comparison with the control group (P < .05). There were no significant differences for pain perception and global functionality. CONCLUSION: The combination of visceral manipulation and conventional physical therapy program demonstrated significant between-groups differences over time for lumbar spine mobility and specific functionality. These gains occurred after 5 sessions, once a week, and were maintained 1 week after the end of the treatment. This study generated data for conduction of a power analysis to inform the design for future clinical research in this line of inquiry.

RESUMO

INTRODUCTION: Down syndrome results in neuromotor impairment that affects selective motor control, compromising the acquisition of motor skills and functional independence. The aim of the proposed study is to evaluate and compare the effects of multiple-monopolar anodal transcranial direct current stimulation and sham stimulation over the primary motor cortex during upper limb motor training involving virtual reality on motor control, muscle activity, cerebral activity and functional independence. METHODS AND ANALYSIS: A randomised, controlled, double-blind, clinical trial is proposed. The calculation of the sample size will be defined based on the results of a pilot study involving the same methods. The participants will be randomly allocated to two groups. Evaluations will be conducted before and after the intervention as well as 1 month after the end of the intervention process. At each evaluation, three-dimensional analysis of upper limb movement muscle activity will be measured using electromyography, cerebral activity will be measured using an electroencephalogram system and intellectual capacity will be assessed using the Wechsler Intelligence Scale for Children. Virtual reality training will be performed three times a week (one 20 min session per day) for a total of 10 sessions. During the protocol, transcranial stimulation will be administered concomitantly to upper limb motor training. The results will be analysed statistically, with a p value≤0.05 considered indicative of statistical significance. ETHICAL ASPECTS AND PUBLICITY: The present study received approval from the Institutional Review Board of Universidade Nove de Julho (Sao Paulo,Brazil) under process number 1.540.113 and is registered with the Brazilian Registry of Clinical Trials (N° RBR3PHPXB). The participating institutions have presented a declaration of participation. The volunteers will be permitted to drop out of the study at any time with no negative repercussions. The results will be published and will contribute evidence regarding the use of this type of intervention on children.

RESUMO

The authors' aim was to investigate the effects of continuous transcranial direct current stimulation (tDCS) combined with virtual reality training on static and functional balance in children with cerebral palsy (CP). Twenty children with CP (6 girls and 14 boys; M age = 7 years 6 months ± 2 years) were randomly allocated to two groups. The experimental group received active tDCS and the control group received sham stimulation during the 10 sessions of virtual reality mobility training protocols. The children were evaluated on 3 occasions (preintervention, postintervention, and 1-month follow-up). Static balance was evaluated using a force plate under 4 conditions: feet on force plate with (a) eyes open and (b) with eyes closed, and feet on foam mat with (c) eyes open and (d) with eyes closed. Functional balance was evaluated using the Pediatric Balance Scale and the Timed Up and Go Test. The analyses demonstrated statistically significant postintervention and follow-up effects favoring the experimental group over the control group with regard to the Pediatric Balance Scale, Timed Up and Go Test, and area of oscillation of the center of pressure when standing on the force plate with eyes open. The present findings suggest that tDCS can potentiate the effects of virtual reality training on static and functional balance among children with CP.

RESUMO

A review of the literature was performed to answer the following questions: Does motor cortex excitability correlate with motor function? Do motor cortex excitability and cortex activation change after a rehabilitation program that results in improvements in motor outcomes? Can the 10-20 electroencephalography (EEG) system be used to locate the primary motor cortex when employing transcranial direct current stimulation? Is there a bihemispheric imbalance in individuals with cerebral palsy similar to what is observed in stroke survivors? the authors found there is an adaptation in the geometry of motor areas and the cortical representation of movement is variable following a brain lesion. The 10-20 EEG system may not be the best option for locating the primary motor cortex and positioning electrodes for noninvasive brain stimulation in children with cerebral palsy.

RESUMO

[Purpose] This systematic review evaluated the presence of sleep-disordered breathing in patients with myasthenia gravis and clarified the role of physiotherapy. [Subjects and Methods] We followed the PRISMA declaration criteria. The evaluation was performed in accordance with the STROBE statement for observational and cross-sectional studies and the CONSORT checklist for clinical trials. Searches were followed by hand on MEDLINE, EMBASE, SciELO, PubMed Central, and the Cochrane Central Register of Controlled Trials. [Results] Our searches yielded a total of 36 studies published between 1970 and 2014. The number of patients involved ranged from 9-490. Of the 36 studies, 19 articles were excluded because they did not meet the inclusion criteria. Therefore, 17 observational, cross-sectional, or clinical studies assessing the quality of sleep and prevalence of sleep disorders in patients with myasthenia gravis were eligible for our review. [Conclusion] Some studies of patients with MG show that patients with MG are associated with poor sleep quality, excessive daytime sleepiness, presence of restless syndrome, and a higher incidence of SDB, while other studies do not report such associations. Therefore, given the current inconclusive evidence and limited literature, further study of sleep disturbances in patients with MG is needed.

RESUMO

PURPOSE: The aim of this review was to compare the effects of rigid and articulated ankle-foot orthoses on gait in children with cerebral palsy (CP). METHOD: A systematic review was carried out in 4 databases. The papers identified were evaluated on the basis of the following inclusion criteria: (1) design--controlled clinical trial; (2) population--children and adolescents with CP; (3) intervention--rigid or articulated ankle-foot orthoses; and (4) outcome--improved motor function and gait performance. RESULTS: Seven controlled studies comparing the effects of different ankle-foot orthoses were found. Studies achieved PEDro scores of 3 and 4 for methodological quality. CONCLUSION: There is evidence supporting the use of an articulated ankle-foot orthosis by children with CP, because of the improved function this type of orthosis provides. However, other studies point out the advantages of a rigid orthosis for children with greater impairment related to spasticity and contractures.
