perturbations , HHS wearers exhibited decreased equilibrium and strategy scores in 10.1 cm HHS , compared with flat shoes and 3.9 and seven cm HHS . Vision played a vital role in the integration of the sensory systems in the postural control process with elevated HH . With respect to the control of the COG movement , the COG movement velocity and directional control declined in 10.1 cm HHS compared with flat shoes and 3.9 cm HHS . During external support surface perturbations , the postural latencies tended to delay with elevated HH . Amplitude scaling increased when HH increased to 3.9 cm compared with flat shoes . Similarly , impaired functional mobility can be detected in 3.9 cm HHS contrary to flat shoes . However , experienced HHS wearers did not show significant higher composite equilibrium scores than novices as the authors hypothesized . No difference in the somatosensory function and postural responses under external perturbations was found between the two groups . Experienced wearers utilized higher proportion of ankle strategy and COG directional control in maintaining postural stability . They perceived higher stability and performed better functional mobility than inexperienced HHS wearers .
In SOT , decreased equilibrium and strategy scores were found in 10.1 cm HHS , compared
