Sensory strategies of postural sway during quiet stance in patients with haemophilic arthropathy.

2017

Introduction: The sensory strategies of postural control in adult haemophilic arthropathy patients are still poorly understood. Aim: To determine sensorial posture-control strategies through postural sway frequency analysis when in a bipedal quiet stance with and without visual stimulus deprivation in healthy subjects and patients with haemophilic arthropathy. Secondarily, to determine the irregularity of postural balance control through sample entropy (SampEn). Methods: A triaxial accelerometer attached at the L3 level determined the displacement and acceleration of the centre of mass (DCoM and ACoM, respectively) under open-and closed-eyes conditions. Sensorial strategies were studied by …
