Estudos de revisão sistemática: um guia para síntese criteriosa da evidência científica

Systematic review studies: a guide for careful synthesis of the scientific evidence Introduction: Aggregation of research evidence to guide clinical practice is one of the main reasons for conducting studies that provide a synthesis of the literature, but it is not the only reason. Systematic reviews are designed to be methodical, explicit and replicable. Such studies may help to guide project development, by indicating new directions for further investigations and identifying which research methods have been used within a given area. Methods: Systematic reviews require straightforward questions, search strategy definition, establishment of study inclusion and exclusion criteria and careful analysis of the selected literature. The development process for reviews of this type includes characterization of each selected study, evaluation of their quality, identification of important concepts, comparison of statistical analyses used and conclusions regarding what the literature tells us about a specific intervention. Such reviews also suggest problems/questions that need further investigation. Systematic review studies follow the structure of original articles. Conclusion: Good systematic reviews are important resources, in the light of the accelerated growth of scientific information. These studies help in producing syntheses of the evidence available in the literature on specific interventions, and may help clinicians and researchers in their work process.Introduction: Aggregation of research evidence to guide clinical practice is one of the main reasons for conducting studies that provide a synthesis of the literature, but it is not the only reason.

Test of grip strength using the Jamar dynamometer

The measurement of grip strength is an important element in hand rehabilitation. Tests of grip strength are often used to assess patients with upper extremity disorders, before and after therapeutic procedures. These tests are simple to administer and if properly conducted, they provide objective information that may contribute to the analysis of hand function. The test protocol must be carefully developed and adequately followed. A well-recommended instrument in the literature is the Jamar dynamometer, with high rates of reliability and validity. This instrument has been accepted as a gold standard for the measurement of grip strength and has been frequently used in clinical practice by occupational and physical therapists. The present study reviews some aspects involved in the measurement of grip strength using the Jamar dynamometer, including the instrument reliability and precision, a suggested protocol for its use, important variables that may influence the results, the use of normative data and the factors that influence grip strength such as the individual’s sex, age, weight and height. Recommendations are made regarding these variables in order to help the clinicians’ conduct appropriate assessments of grip strength.

Estudo comparativo sobre o desempenho perceptual e motor na idade escolar em crianças nascidas pré-termo e a termo

The objective of this study was to compare the perceptualmotor performance in school age children who were born preterm and full term. Two groups of children, ages 5 to 7, participated in this study. Group I had 35 children, from low-income families, born up to the 34 week of gestation and/or weight bellow 1500 g. Group II had 35 full-term children, matched by age, gender and socioeconomic status to the children in Group I. Children were tested on the Bender gestalt, the motor accuracy test and on balance and postural responses measures. The preterm group obtained significantly lower scores in the majority of the tests. These besides reinforcing the importance of the follow-up of preterm children up to school age, also indicate the need to stimulate the fine motor and postural control Devment, even among preterm children who do not show evidence of neurological impairment.

Efeitos do uso de órtese na mobilidade funcional de crianças com paralisia cerebral

The Effects of the Use of Orthoses on the Functional Mobility of Children with Cerebral Palsy Objective: To compare the motor performance of children with cerebral palsy (CP) under two conditions: with and without orthoses. Method: Twenty children with CP were evaluated using the Gross Motor Function Measure test (GMFM), a modified version of the Physicians Rating Scale (PRS) locomotion assessment, and an interview with their parents to evaluate the use of orthoses in their daily routine. Results: The ANOVA test was used to evaluate the effect of orthosis use on the children’s mobility, and it revealed that, when orthosis was used, the means for gross motor function and gait assessments were significantly higher. The interviews confirmed that the use of orthoses was included in the daily routine, and the parents demonstrated positive perceptions regarding the use of such devices. Conclusion: Orthoses improved the performance of routine daily motor tasks among the children with CP, and this finding may serve to guide the assessment and intervention processes of professionals who work with this clientele.

Classificação da função motora e do desempenho funcional de crianças com paralisia cerebral

OBJECTIVE: To classify children with cerebral palsy (CP) using classification systems for mobility and manual function; to compare groups of children with CP regarding gross motor function and functional performance outcomes; and to evaluate associations between the functional classifications and the scores obtained in the outcomes that were investigated. METHODS: Thirty children with CP were classified using the Gross Motor Function Classification System (GMFCS) and the Manual Abilities Classification System (MACS), and were divided into three groups, based on their classification (mild, moderate or severe) in each of these systems. Gross motor function was documented using the Gross Motor Function Measure (GMFM-66) test, while functional abilities and the caregivers assistance regarding self-care and mobility were documented using the Pediatric Evaluation of Disability Inventory (PEDI). RESULTS: One-way ANOVA showed that the groups were significantly different regarding the GMFM-66 and PEDI results. Post-hoc comparison tests (Scheffe) revealed that the children with moderate impairment (GMFCS) had functional abilities and caregiver support that were similar to those of the mildly impaired children. However, the moderate children (MACS) were not different from the severe children. Spearman rank correlations showed strong and significant inverse associations between the functional classifications and the results from the PEDI and GMFM-66 tests. CONCLUSIONS: The results suggest that the MACS and GMFCS functional classifications are good indicators of the manual function and mobility of children with CP. These classifications may be useful in the processes of evaluation and intervention planning.OBJECTIVE: To classify children with cerebral palsy (CP) using classification systems for mobility and manual function; to compare groups of children with CP regarding gross motor function and functional performance outcomes; and to evaluate associations between the functional classifications and the scores obtained in the outcomes that were investigated.

A profissionalização da fisioterapia em Minas Gerais

Professionalization of physical therapy in Minas Gerais Objective: To identify the roots of physical therapy in Minas Gerais, in order to understand the professionalization process and the development of identity among physiotherapists in this state, based on a qualitative approach, oral histories and analysis of documents. Methods: The focus of this study was primarily Belo Horizonte between 1950 and 1980. The theoretical reference point utilized was the sociology of professions and the five steps towards professionalization described by Wilensky (1964) were taken as the guide. These were: the need for exclusive dedication to the profession; the establishment of education and selection procedures; the creation of a professional association; professional regulation; and the adoption of a code of ethics. A survey was conducted, utilizing semi-structured interviews to gather statements from key leaders, based on serial sampling and content analysis. Results: It was found that the process of professionalization within physical therapy in Minas Gerais was influenced by medical hegemony within the health field. Lack of definition regarding functions and competencies were factors that had led to both internal and external conflicts. Conclusions: To ensure effective affirmation of physical therapy as a profession, it is necessary to define the specific limits of its knowledge and skills (theoretical and practical), so as to better identify the role of the physiotherapist within multidisciplinary health teams.

Efeitos da estimulação elétrica funcional nos músculos do punho e dedos em indivíduos hemiparéticos: uma revisão sistemática da literatura

Effects of functional electrical stimulation applied to the wrist and finger muscles of hemiparetic subjects: a systematic review of the literature Background: a systematization of the available evidence regarding the effects of electrical stimulation for hemiplegic patients following stroke is needed. Objective: to conduct a systematic review of the literature related to the effects of functional electrical stimulation for the wrist and finger muscles of adult hemiplegic patients. Method: a search for studies documenting the effects of electrical stimulation on neuromuscular, musculoskeletal and functional characteristics was carried out in Medline, Lilacs and PEDro databases between February and March 2006. Data were extracted in a standardized manner from each study, and methodological quality was assessed using the PEDro scale. Results: Eight randomized studies were reviewed. The scores on the methodological quality of revised studies were between 3/10 and 7/10 in the PEDro scale. Although the diversity of protocols, participants’ characteristics and instrumentation prevented pooling of results, a synthesis in levels of evidence demonstrated strong evidence for positive effects of electrical stimulation on muscle strength, tonus, motor function and use of the upper limb in daily life. Moderate evidence was found for effects on dexterity and limited evidence for effects on motor coordination and independence in self-care activities. There was no evidence for gains in range of active wrist extension. Conclusion: Despite methodological limitations, randomized studies reported positive effects of electrical stimulation on wrist and fingers, suggesting that this therapy might be effective for promoting function of the affected upper limb of hemiplegic individuals.

Padrão respiratório e movimento toracoabdominal de crianças respiradoras orais

OBJECTIVE: To characterize the breathing pattern and thoracoabdominal motion of mouth-breathing children aged between eight and ten years and to compare these characteristics with those of nose-breathing children of the same ages. METHODS: This observational study was carried out in a university laboratory. The sample size of 50 subjects was estimated based on the results of a pilot study with ten children in each group (total of 20 children) and considering a significance level of 0.05 and statistical power of 0.80. Twenty-six mouth-breathing and 25 nose-breathing children participated. Calibrated respiratory inductive plethysmography was used to analyze the following variables, among others: respiratory frequency (f), rib cage contribution towards tidal volume (%RC/Vt), phase angle (PhAng) and the ratio between time taken to reach peak inspiratory flow and total inspiratory time (PifT/Ti). Peripheral oxygen saturation of hemoglobin (SpO2) was measured using pulse oximetry. Statistical analysis was performed using the Students t test for independent groups or the Mann-Whitney U test, according to the sample distribution of the variables. RESULTS: A total of 4,816 respiratory cycles were analyzed: 2,455 from mouth-breathers and 2,361 from nose-breathers, with a mean of 94 cycles per child. No statistically significant differences were observed between the groups, for the variables studied (f=20.00±2.68 versus 20.73±2.58, p=0.169; %RC/Vt=39.30±11.86 versus 38.36±10.93, p=0.769; PhAng=14.53±7.97 versus 13.31±7.74, p=0.583; PifT/Ti=57.40±7.16 versus 58.35±5.99, p=0.610; SpO2=96.42±1.52% versus 96.88± 1.01%, p=0.208; respectively). CONCLUSIONS: These results suggest that mouth-breathing children show breathing patterns and thoracoabdominal motion that are similar to those of nose-breathing children in the same age group.
