Different postural stability may be a contributor to secondary injuries in
individuals with flexible flatfeet (FF) compared to those with neutral feet (NF).
However, the differences between static and dynamic stability of FF and NF have
not been examined. This study compared the static and dynamic stability of
subjects with FF and NF and investigated the relationship between static and
dynamic stability. Twenty-eight subjects (14 each in the FF and NF groups)
performed three tasks (single leg standing with eyes open, with eyes closed, and
the Y balance test). We quantified the center of pressure (COP) speed and Y
balance test score (Y score) within the tasks. COP speed was significantly
greater in the FF group than in the NF group under both conditions (eyes open and
closed) and directions (anteroposterior and mediolateral). Y scores did not
differ significantly between the two groups. No significant relationship was
observed between the COP speed and Y score in either group. These results show
that individuals with FF have different static stabilities, but not dynamic
stabilities, compared with those with NF. This might indicate the absence of a
relationship between static and dynamic stabilities.
