ABSTRACT
The aim was to describe trunk control in ambulant and non-ambulant patients with Duchenne muscular dystrophy (DMD). We conducted a cross-sectional analysis of a sample of 50 DMD patients, (M age = 16.7 years) who underwent the Segmental Assessment of Trunk Control (SATCo). A seven-level scale of trunk control was used (1: head control only; 7: control of entire trunk while unsupported). Static, active and reactive posture control were evaluated in ambulant and non-ambulant patients. Inter-rater reliability for all assessments was evaluated by calculating the kappa coefficient. More advanced disease (having higher Vignos scores), was associated with poorer trunk control. Ambulant patients showed better trunk control than non-ambulant patients (p = 0.003). There was strong inter-rater agreement for SATCo scale scores.

RESUMO O objetivo foi avaliar o controle de tronco em pacientes deambulantes e não-deambulantes com distrofia muscular de Duchenne (DMD). Estudo transversal composto por 50 pacientes com diagnóstico de DMD, média de idade 16,72 anos, avaliados pela Segmental Assessment of Trunk Control (SATCo). A escala apresenta sete níveis para o controle de tronco incluindo-se desde o controle de cabeça até controle de tronco total em que o paciente permanece sem apoio. Controle estático, ativa e reativa de postura do tronco foram avaliados em pacientes deambulantes e não-deambulantes. Para a confiabilidade entre os avaliadores, empregou-se a análise estatística Kappa. Quanto maior a pontuação na escala Vignos, maior a frequência de pacientes com DMD que apresentam pior controle de tronco. Pacientes deambulantes apresentaram controle de tronco melhor do que os pacientes não-deambulantes (p = 0,003). Houve forte confiabilidade entre avaliadores para a pontuação da escala SATCo.
