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

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).
