The said findings indicate the followings: for people suffering from single side functional ankle joint instability, the bal-ancing ability of the ill foot is slightly weaker than that of the corresponding foot of normal people, and also weaker than that of the healthy foot, while the balancing ability of the healthy foot has a certain compensation function due to the lack of balancing ability of the ill foot, which results in that its balancing ability tends to be slightly better that of the corresponding foot of normal people. |
