Walking training machine

The present invention relates to a walking training machine, and particularly to a walking training machine capable of reliably simulating gait movements during walking.

Walking must rely on the coordination of the body's nerves, muscles, and bones to achieve the effect of moving the body forward. To walk stably, you need to have sufficient attention, muscle strength, and appropriate movement control capabilities. For people, the decline of physical functions leads to prone to walking disorders. In severe cases, they often fall down, which affects their health and daily life.

In order to help the elderly to perform rehabilitation training, for example, the walking exercise device disclosed in JP2002325860 uses the first leg mounting device and the second leg mounting device to move back and forth alternately to achieve the effect of leg training, as disclosed in JP2001309993 The sports machine uses the track sliding method to drive the pedal back and forth. As for the multifunctional gait rehabilitation training device disclosed in CN105167959, the slider drives the pedal to move forward and backward, and in addition, the pedal makes the pedal rotate. However, the aforementioned patents cannot make the pedals truly show the motion trajectory when walking, so the training effect that can be achieved is actually limited.
