Comunicação e transtornos do espectro do autismo: análise do conhecimento de professores em fases pré e pós-intervenção

Objetivo analisar o conhecimento de professores de ensino fundamental sobre a comunicação de pessoas com transtornos do espectro do autismo, em dois momentos distintos, pré e pós-intervenção. Métodos trata-se de um estudo descritivo comparativo, em que participaram 160 professores de escolas municipais de ensino fundamental, de ambos os gêneros, com idades entre 23 e 65 anos. Para verificar o conhecimento dos professores sobre a comunicação nos transtornos do espectro do autismo, foi elaborado e aplicado um questionário especificamente para este estudo. O instrumento, oferecido aos professores, foi aplicado em dois momentos distintos, pré e pós-intervenção. O procedimento de intervenção constou de dois encontros, de quatro horas cada, conduzidos por fonoaudiólogos e entrega de manual de orientação sobre os transtornos do espectro do autismo, com ênfase em aspectos da comunicação e linguagem. Foram analisadas e comparadas as respostas pré e pós-intervenção. Os resultados foram tratados estatisticamente (p<0,05 e em alguns casos p<0,01; foi utilizado o teste de Qui-quadrado para Proporções). Resultados foi possível observar que os professores apresentavam conhecimento restrito sobre a comunicação nos transtornos do espectro do autismo e sobre esses quadros clínicos de modo geral. Além disso, verificou-se aumento significante de respostas corretas por parte dos professores após a intervenção. Conclusão constatou-se um restrito conhecimento dos professores sobre a comunicação nos transtornos do espectro do autismo e efeitos positivos do procedimento de intervenção, por meio da análise comparativa entre as fases pré e pós-intervenção, que evidenciou aumento significante de respostas adequadas sobre os transtornos do espectro do autismo.

A controlled clinical trial on the effects of motor intervention on balance and cognition in institutionalized elderly patients with dementia

Purpose: To analyse the effects of two interventions on the cognition and balance of institutionalized elderly people with mixed dementia.Methods: Fifty-four participants were allocated into three groups. Group 1 was assisted by an interdisciplinary programme comprising physiotherapy, occupational therapy and physical education. A physiotherapist alone carried out the intervention in group 2. Group 3 was considered as control. Assessors were blinded to guarantee the absence of bias. Cognitive functions were analysed with the Mini-Mental State Examination and the Brief Cognitive Screening Battery. Balance was assessed with the Berg Balance Scale and the Timed Get-Up-and-Go Test. Multiple analysis of variance (MANOVA) was used to test possible main effects of the interventions.Results: The results showed benefits on the balance of subjects in both groups 1 (F=3.9, P < 0.05) and 2 (F= 3.1, P < 0.05), compared with group 3. MANOVA did not indicate benefits on the cognitive functions between groups 1 and 3 (F= 1.1, P > 0.05) and groups 2 and 3 (F= 1.6, P > 0.05). However, univariate analysis indicated some benefits of the interdisciplinary intervention on two specific domains measured by the Brief Cognitive Screening Battery (F=26.5, P < 0.05; F= 4.4, P < 0.05).Conclusion: Six months of multidisciplinary or physiotherapeutic intervention were able to improve a person's balance. Although global cognition did not improve through treatment, when the intervention was carried out on a multidisciplinary basis we observed an attenuation in the decline of global cognition on two specific cognitive domains. Exercises applied in different contexts may have positive outcomes for people with dementia.

Functional dependence and caregiver burden in Alzheimer's disease: a controlled trial on the benefits of motor intervention

Background: Cognitive decline has a negative impact on functional activities in Alzheimer's disease. Investigating the effects of motor intervention with the intent to reduce the decline in functionality is an expected target for patients and caregivers. The aim of this study was to verify if a 6-month motor intervention programme promoted functionality in Alzheimer's patients and attenuated caregivers' burden. Methods: The sample comprised 32 community patients with Alzheimer's disease and their 32 respective caregivers. Patients were divided into two groups: 16 participated in the motor intervention programme and 16 controls. Subjects performed 60 minutes of exercises, three times per week during the 6-month period, to improve flexibility, strength, agility and balance. Caregivers followed the procedures with their patients during this period. Functionality was evaluated by the Berg Functional Balance Scale and the Functional Independence Measure. Caregivers completed the Neuropsychiatric Inventory Caregiver Distress Scale and the Zarit Carer Burden Scale. Two-way ANOVA was used to verify the interaction between time (pre- and post-intervention) and the motor intervention program. Results: While patients in the motor programme preserved their functionality, as assessed by the Functional Independence Measure, the controls suffered a relative decline (motor intervention group: from 109.6 to 108.4 vs controls: from 99.5 to 71.6; P= 0.01). Patients from motor intervention also had better scores than the controls on functional balance assessed by Berg scale (F: 22.2; P= 0.001). As assessed by the Neuropsychiatric Inventory and Zarit scale, burden was reduced among caregivers whose patients participated in the motor intervention programme compared with caregivers whose patients did not participate in this programme (Neuropsychiatric Inventory, caregiver's part: F: 9.37; P= 0.01; Zarit: F: 11.28; P= 0.01). Conclusion: Patients from the motor intervention group showed reduced functional decline compared to the controls, and there was an associated decrease in caregivers' burden.

Multimodal exercise intervention improves frontal cognitive functions and gait in Alzheimer's disease: A controlled trial

Aim: The objective of the present study was to investigate the effect of a multimodal exercise intervention on frontal cognitive functions and kinematic gait parameters in patients with Alzheimer's disease. Methods: A sample of elderly patients with Alzheimer's disease (n=27) were assigned to a training group (n=14; aged 78.0±7.3years) and a control group (n=13; aged 77.1±7.4years). Multimodal exercise intervention includes motor activities and cognitive tasks simultaneously. The participants attended a 1-h session three times a week for 16weeks, and the control participants maintained their regular daily activities during the same period. The frontal cognitive functions were evaluated using the Frontal Assessment Battery, the Clock Drawing Test and the Symbol Search Subtest. The kinematic parameters of gait-cadence, stride length and stride speed were analyzed under two conditions: (i) free gait (single task); and (ii) gait with frontal cognitive task (walking and counting down from 20 - dual task). Results and discussion: The patients in the intervention group significantly increased the scores in frontal cognitive variables, Frontal Assessment Battery (P<0.001) and Symbol Search Subtest (P<0.001) after the 16-week period. The control group decreased the scores in the Clock Drawing Test (P=0.001) and increased the number of counting errors during the dual task (P=0.008) after the same period. Conclusion: The multimodal exercise intervention improved the frontal cognitive functions in patients with Alzheimer's disease. © 2012 Japan Geriatrics Society.

Efficacy of a perceptual and visual-motor skill intervention program for students with dyslexia

Purpose: To verify the efficacy of a perceptual and visual-motor skill intervention program for students with dyslexia. Methods: The participants were 20 students from third to fifth grade of a public elementary school in Marília, São Paulo, aged from 8 years to 11 years and 11 months, distributed into the following groups: Group I (GI; 10 students with developmental dyslexia) and Group II (GII; 10 students with good academic performance). A perceptual and visual-motor intervention program was applied, which comprised exercises for visual-motor coordination, visual discrimination, visual memory, visual-spatial relationship, shape constancy, sequential memory, visual figure-ground coordination, and visual closure. In pre- and post-testing situations, both groups were submitted to the Test of Visual-Perceptual Skills (TVPS-3), and the quality of handwriting was analyzed using the Dysgraphia Scale. Results: The analyzed statistical results showed that both groups of students had dysgraphia in pretesting situation. In visual perceptual skills, GI presented a lower performance compared to GII, as well as in the quality of writing. After undergoing the intervention program, GI increased the average of correct answers in TVPS-3 and improved the quality of handwriting. Conclusion: The developed intervention program proved appropriate for being applied to students with dyslexia, and showed positive effects because it provided improved visual perception skills and quality of writing for students with developmental dyslexia.
