When the external balance is distur

When the external balance is disturbed, different postural strategies were used to maintain the projection of the center of gravity in the support base.Minor postural disorders are mainly caused by the ankle and hip strategies.When the external interference is large, the step strategy is adopted to adjust the stride of the center of gravity, so as to maintain the stability of the center of gravity and support base.One of the typical motor disorders in hemiparesis is decreased walking function and gait asymmetry.Asymmetric gait patterns can cause walking instability, increased fall risk, and decreased walking efficiency.Digital treadmill 3 D computer gait system is one of the standard methods for gait assessment, but its application is limited due to the influence of the site and equipment.Balance function is one of the factors affecting gait, and the evaluation of balance function can reflect its gait to some extent.
