The Effects of Haemophilia on the Postural Control of Adolescents
AbstractA small number of studies have reported that children and adults with haemophilia have impaired balance control and show faster body sway during upright stance than healthy individuals. A decrease of somatosensory information due to multiple bleedings has been suggested to explain this difference. Therefore, the objective of this study was to examine if haemophilia is related to a decreased balance control under altered visual and proprioceptive conditions in male adolescents. Postural sway of healthy (n = 12, Age = 14.8 ± 1.4 years; BMI = 19.8 ± 1.8 kg/m2) and haemophiliac (n = 8, Age = 15.0 ± 1.4 years; BMI = 20.4 ± 3.2 kg/m2) male adolescents was measured with a force platform for normal quiet stance lasting 30 s with open and closed eyes on hard and foam floor conditions. The ANOVA revealed a significant Group × Vision × Proprioception (F(1,18) = 5.861, p < 0.05) interaction. Both groups showed an increased centre of pressure (COP) speed when vision and proprioception are challenged. Planned comparisons revealed that the haemophiliac group oscillated at a faster COP speed than the healthy group when vision is altered in hard floor (1.11 ± 0.27 versus 0.76 ± 0.19 cm/s; p < 0.05) and foam floor (6.83 ± 1.68 versus 4.89 ± 1.05 cm/s; p < 0.01) conditions. More important, haemophiliac adolescents were more disturbed by the proprioceptive condition and had a significantly higher COP speed on the foam even if vision is available (3.02 ± 0.47 versus 2.34 ± 0.45 cm/s; p < 0.05) compared to the healthy adolescents. In conclusion, haemophilia clearly affects postural control in altered sensory conditions. Our results suggest that haemophilia has a negative impact on the capacity of male adolescents to adequately use proprioceptive information for posture control. View Full-Text
