after the patient has been subjected to the operation treatment for the leg injury, the wrist ring 101 of the device is fitted over the ankle of the patient, the feet of the patient are fixed to the foot base plate 103, and the patient performs the walking training by using aids such as a crutch and a walker. When the patient's foot is stepped on to the ground, the patient's leg is stressed, the patient's foot is stepped on the sole plate 103, and the sole plate 103 applies pressure to the ground. At this time, the front pressure sensor 104 and the rear pressure sensor 105 located on the sole plate 103 are subjected to stress induction, the front pressure sensor 104 detects a real-time pressure value applied to the ground by the toe end of the sole plate 103, the rear pressure sensor 105 detects a real-time pressure value applied to the ground by the heel end of the sole plate 103, the processor sums the real-time pressure values detected by the front pressure sensor 104 and the rear pressure sensor 105 to obtain a sum of the real-time pressure values, and the controller controls the display to display the sum of the real-time pressure values, so that doctors and patients can know the stress condition of the feet. The supporting force of auxiliary tools such as a crutch, a walking aid and the like on a patient is adjusted, so that the foot stress of the patient is adjusted, and the leg stress of the patient is adjusted until the leg stress of the patient is adjusted to a loading interval suggested by a doctor. Thereby preventing the patient from reaching the effect of rehabilitation treatment when the load of the affected limb is smaller than the load interval recommended by the staged doctor. And the problems of fracture at the fracture part, non-union of fracture and the like caused when the load of the patient's affected limb exceeds the load interval recommended by the staged doctor are avoided.
When a patient just starts to walk training, the patient can walk by using the toe in order to avoid discomfort, but the training mode not only reduces the training effect of the patient walking training, but also has the risks of fixing bending, fracture shifting and the like of the fracture part of the patient, thereby being unfavorable for recovery of the affected limb after the operation of the patient. Therefore, the device calculates the difference between the real-time pressure values of the front pressure sensor 104 and the rear pressure sensor 105 through the processor and displays the difference through the display, so that a doctor can know the gait of the patient in real time, judge whether the patient walks by using the toe or the heel when walking, and recommend the patient to adjust the gait according to the stress condition of the foot when the patient walks, thereby avoiding the problems when the patient is trained.
The plantar pressure feedback device for progressive weight bearing patients can prompt a doctor and the patient of leg stress conditions and the patient gait when the doctor and the patient perform walking training, so that the leg stress of the patient is in a weight bearing interval recommended by the doctor, and meanwhile, the gait can be timely adjusted, thereby improving the walking training effect and avoiding the risks of fracture at a fracture part, fracture nonunion, fracture displacement and the like.

When the patient walks, if the difference between the real-time pressure values detected by the front pressure sensor 104 and the rear pressure sensor 105 is larger than the difference between the preset pressure values when the patient walks by using the toes, at this time, the controller controls the power device 202 to act, and the power device 202 drives the connecting rod 102 to rotate, so that the included angle between the connecting rod 102 and the sole 103 is reduced, and the toe of the patient is tilted, so that the heel of the patient faces the ground, and when the patient walks, the heel of the patient is grounded, so that the gait of the patient is automatically adjusted, the patient is assisted to walk, and the fracture displacement risk of the fracture of the patient is further avoided.
As a preferred solution, a timer is also electrically connected to the controller, and the timer is used for calculating the time of single compression of the front pressure sensor 104 and the rear pressure sensor 105.
