Postural control evolution in Duchenne muscular dystrophy - longitudinal study.

Abstract

Aim: To assess the evolution of postural control in individuals with Duchenne Muscular Dystrophy (DMD) over a 12-month period and to assess postural control under different sensory conditions, identifying the demands on the sensory systems.

Methods: Longitudinal study with individuals with DMD, Vignos stages 1 to 6. Postural control was assessed using Wii Balance Board with modified Sensory Organization Test (MSOT). Center of Pressure (COP) displacement velocity and displacement area were analyzed.

Results and conclusion: Postural control of 16 individuals worsened over 12 months. Significant decline was already evident at 6 months. There was a worsening of performance as the sensory conditions of MSOT progressed.
