  • Publication number: 20250064345
    Abstract: A gait evaluating system including a processor is provided. The processor identifies whether a gait type of the user belongs to a normal gait, a non-neuropathic gait or a neuropathic gait based on step feature values of a user and walking limb feature values of the user. In response to that the gait type of the user belongs to the non-neuropathic gait, the processor controls the display panel to display a first auxiliary information, a second auxiliary information, and a third auxiliary information. The first auxiliary information indicates a potential sarcopenia of the user. The second auxiliary information indicates a dietary guideline for muscle building and muscle strengthening. The third auxiliary information shows a motion instruction video for regaining or maintaining muscle strength of the user.
