13), Barthel Index (>13) and Lysholm Scoring Scale (>84). Seventeen 67 ± 9 year-old elderly women from a nursing home were divided into 2 groups at random: the control group (CG, N = 9) participated in enjoyable cultural activities; the stretching group (SG, N = 8) performed active stretching of hamstrings, 4 bouts of 1 min each. Both groups were supervised three times per week over a period of 8 weeks. Peak torque was assessed by an isokinetic method. Both groups were evaluated by a photogrammetric method to assess muscle-tendon length of uni- and biarticular hip flexors and hamstring flexibility. All measurements were analyzed before and after 8 weeks by two-way ANOVA with the level of significance set at 5%. Hamstring flexibility increased by 30% in the SG group compared to pre-training (76.5 ± 13.0° vs 59.5 ± 9.0°, P = 0.0002) and by 9.2% compared to the CG group (76.5 ± 13.0° vs 64.0 ± 12.0°, P = 0.0018). Muscle-tendon lengths of hip biarticular flexor muscles (124 ± 6.8° vs 118.3 ± 7.6°, 5.0 ± 7.0%, P = 0.031) and eccentric knee extensor peak torque were decreased in the CG group compared to pre-test values (-49.4 ± 16.8 vs -60.5 ± 18.9 Nm, -15.7 ± 20%, P = 0.048). The stretching program was sufficient to increase hamstring flexibility and a lack of stretching can cause reduction of muscle performance.]]>
INTRODUÇÃO: Com a finalidade de investigar a etiologia dos sintomas osteomusculares em professores, estudos tem abordado a relação entre o trabalho docente e as possíveis particularidades da profissão que podem levar ao adoecimento físico dos professores. OBJETIVO: Analisar os sintomas osteomusculares de professores do ensino fundamental da cidade de Matinhos (PR). MATERIAIS E MÉTODOS: Foram avaliados 126 professores (120 mulheres e seis homens, 38,6 ± 9 anos) por meio de um questionário contendo dados gerais e ocupacionais e pelo questionário nórdico. Análises estatísticas univariadas desses questionários foram realizadas com o teste qui-quadrado. Um modelo linear logístico múltiplo foi estabelecido para predizer as variáveis respostas do questionário nórdico a partir das variáveis independentes do questionário de dados gerais e ocupacionais. RESULTADOS: A presença de dor não indicou associação significativa com a idade, realização de atividade física, número de alunos por classe e tempo de profissão (p > 0,05), relacionou-se apenas com o número de classes que lecionavam (p = 0,02). Porém, a presença de dor nos últimos 12 meses teve relação com o impedimento de realizar atividade nos últimos 12 meses e a procura por algum profissional da saúde (p > 0,05). Dos participantes, 95,2% apresentaram algum sintoma osteomuscular. As áreas mais atingidas foram lombar (51,5%), região dorsal (49,2%), ombro (49,2%) e pescoço (47,6%). CONCLUSÕES: Os professores apresentaram elevada prevalência de sintomas osteomusculares, especialmente na lombar, nos ombros e na região dorsal, os quais, por sua vez, provocaram o impedimento de realizar atividades cotidianas.
¹ Registro Brasileiro de Ensaio Clínico (REBEC) [Brazilian Registry of Clinical Trials]: RBR-6r7ww5.Fisioter Mov. 2015 July/Sept;28(3):535-44 Rodrigues EV, Gomes ARS, Guimarães ATB, Drabovski B, Rox R, Ramos FS, et al. 536 symptoms related to the lower limbs of public elementary school teachers. Materials and methods: Thirtyone female teachers were divided into two groups: control (CG, n = 15) and muscular endurance training (TG, n = 16). The training consisted of two sets of 15 repetitions of exercises for quadriceps and hamstring muscle groups, twice a week, for 7 weeks, which were conducted with 50% of 10 repetition maximum(10RM) (first to fourth week) and 60% of 10 RM (fifth to seventh week). Musculoskeletal symptoms (Nordic Musculoskeletal Questionnaire), isometric peak torque (Load cell) and muscle strength (10RM) were assessed before and after intervention. ANOVA for repeated measures and Tukey post hoc were used to analyse strength and peak torque of quadriceps and hamstrings and Chi-square goodness-of-fit test were used to analyse the frequency of occurrence of osteomuscular symptoms. Results: The highest incidence of symptoms was found in the lumbar region in both groups. Training caused increased muscle strength of the quadriceps and hamstrings, but there were no significant differences in either the peak torque in the quadriceps and hamstrings or in the reduction of musculoskeletal symptoms. Conclusion: The exercise program performed in this study increased the dynamic strength in the TG in relation to the CG, but did not alter the incidence of symptoms in the lumbar region and lower limbs in neither of the groups. Thus, results suggest that the duration of intervention may not have been enough to increase peak torque and decrease musculoskeletal symptoms.[P]Keywords: Work-related musculoskeletal disorders.

Objetivo: Avaliar os efeitos do treinamento de resistência muscular na força muscular e nos sintomas osteomusculares relacionados aos membros inferiores de professoras do ensino público fundamental. Materiais e métodos: Trinta e uma professoras foram divididas em dois grupos: controle (GC, n = 15) e treinamento de resistência muscular (GT, n = 16). O treinamento consistiu em 2 séries de 15 repetições de exercícios para quadríceps e isquiotibiais, 2 vezes por semana, durante 7 semanas, sendo realizados com 50% de 10 Repetições Máximas (10RM) (1a-4a semanas) e com 60% de 10RM (5a-7a semanas).
