Abstract in Portuguese
Objetivo. Investigar os efeitos e a segurança de um programa de exercícios físicos supervisionados em parâmetros da doença, capacidade física e qualidade de vida relacionada à saúde em pacientes com dermatomiosite juvenil (DMJ). Métodos. Estudo longitudinal e prospectivo com 10 pacientes com DMJ crônica e com atividade leve. O programa de exercícios consistiu de treinos aeróbios e de resistência duas vezes por semana. Nos momentos inicial e 12 semanas após a intervenção foram avaliadas força e função musculares, condicionamento aeróbio, composição corpórea, escores da DMJ e qualidade de vida relacionada à saúde. Resultados. Pediatric Quality of Life Inventory do paciente e dos pais melhoraram após a intervenção (8,3%; p=0,0008 e 8,7%; p=0,027, respectivamente). Disease Activity Score reduziu (-30,6%; p=0,021) e Childhood Muscle Assessment Scale melhorou (2,5%; p=0,009), enquanto Manual Muscle Testing apresentou uma tendência à significância estatística (2,2%; p=0,081). O pico de consumo de oxigênio e o tempo para exaustão aumentou em 13,3% (p=0,001) e 18,2% (p=0,003), respectivamente, enquanto a frequência cardíaca de repouso diminuiu em 14,7% (p=0,006), indicando importantes adaptações cardiovasculares ao exercício. A força muscular dos membros superiores e inferiores e a função muscular também melhoraram significantemente após o programa (p < 0,05). A densidade mineral aparente do corpo total e da coluna lombar aumentaram significantemente após os treinos (1,44%; p=0,044 e 2,85%; p=0,008, respectivamente). Conclusão. Pela primeira vez na literatura foi mostrado que um programa de exercícios físicos supervisionados por 12 semanas é seguro e capaz de melhorar força e função musculares, condicionamento aeróbio, massa óssea, atividade da doença, e qualidade de vida relacionada à saúde em pacientes com DMJ crônica e leve, em atividade ou em remissão

Abstract in English
Objective. To investigate the effects and safety of a supervised exercise training program on health parameters, physical capacity, and health-related quality of life in patients with mild and chronic juvenile dermatomyositis (DM). Methods. This was a prospective longitudinal study following 10 children with mild and chronic juvenile DM (disease duration >1 year). The exercise program consisted of twice-a-week aerobic and resistance training. At baseline and after the 12-week intervention, we assessed muscle strength and function, aerobic conditioning, body composition, juvenile DM scores, and health-related quality of life. Results. Child self-report and parent proxy-report Pediatric Quality of Life Inventory scores were improved after the intervention (8,3%; P = 0.0008 and 8,7%; P = 0.027, respectively). Importantly, after exercise, the Disease Activity Score was reduced (-30.6%; P = 0.021) and the Childhood Muscle Assessment Scale was improved (2.5%; P = 0.009), whereas the Manual Muscle Testing presented a trend toward statistical significance (2.2%; P = 0.081). The peak oxygen consumption and time-to-exhaustion were increased by 13.3% (P = 0.001) and 18.2% (P = 0.003), respectively, whereas resting heart rate was decreased by 14.7% (P = 0.006), indicating important cardiovascular adaptations to the exercise program. Upper and lower extremity muscle strength and muscle function also improved significantly after the exercise training (P < 0.05). Both the whole-body and the lumbar spine bone mineral apparent density were significantly increased after training (1.44%; P = 0.044 and 2.85%; P = 0.008, respectively). Conclusion. We showed for the first time that a 12-week supervised exercise program is safe and can improve muscle strength and function, aerobic conditioning, bone mass, disease activity, and health-related quality of life in patients with active and non-active mild and chronic juvenile DM with near normal physical function and quality of life
