The human body balance ability is an important physiological function, and is the basic ability to ensure that the human body keeps stable standing, walking and completing complex actions. Balance is classified into static balance, i.e., the ability of a human body or a part of a human body to maintain a stable state when the body or part is in a specific posture, such as a sitting posture or a standing posture, and dynamic balance. Dynamic balance includes various autonomous movements performed by the human body, and the ability of the human body to maintain a stable state after interfering with the outside.

Moreover, the traditional balance board can not be adjusted according to the degree of illness of the patient.
In order to solve the above-mentioned problems, an embodiment of the present application discloses a balance evaluation device including: the pressure measurement modules are dispersedly arranged at the bottom of the balance evaluation device and are used for measuring pressure signals generated by the object to be measured in the balance evaluation process; a controller coupled to each of the pressure measurement modules for receiving the pressure signal, the controller further configured to: obtaining balance evaluation parameters of a balance evaluation device, wherein the balance evaluation parameters comprise evaluation speed and evaluation time; and generating a balance evaluation result by using the balance evaluation parameter.
Illustratively, the main structure of the balance evaluation device may be a walking machine or a running machine, or a device similar to a walking machine. As shown in fig. 1, the present application describes a walking machine 2 as a main body of a balance evaluation device. Wherein, the pressure measuring module 6 is arranged at the bottom of the walking machine 2, and the controller 3 is arranged on the walking machine 2. In some other embodiments, the controller 3 may also be provided outside the walker 2.
Alternatively, the controller 3 may acquire the balance evaluation parameter through a data input device. Illustratively, the balance evaluation device may be a human-computer interaction module 1, the controller 3 may be connected to the human-computer interaction module 1, the user inputs the evaluation speed and the evaluation time through the human-computer interaction module 1, and the human-computer interaction module 1 transmits the evaluation speed and the evaluation time to the controller 3.

Specifically, as shown in fig. 1, the human-computer interaction module 1 is disposed on the upper portion of the walking machine 2. The human-computer interaction module 1 may include a human-computer interaction panel, and a touch display screen is disposed on the human-computer interaction panel. The user can input the body data of the object to be detected by touching the touch display screen, such as height data, age data or injury grade. The human-computer interaction module 1 sends the body data to the controller 3, and the controller 3 calculates the balance evaluation parameters according to the body data of the object to be measured.
After obtaining the balance evaluation parameters, the controller 3 generates a balance evaluation result by using the balance evaluation parameters. Specifically, the controller 3 may generate a control instruction according to the balance evaluation parameter, send the control instruction to the walking machine 2, and control the walking machine 2 to operate at the evaluation speed for the evaluation time to perform the balance evaluation on the object to be tested. In the process, the pressure measuring module 6 can measure a pressure signal generated by the object to be measured in the walking process and send the pressure signal to the controller 3. And the controller 3 calculates the coordinate value of the pressure center of the object to be measured according to the coordinate value of the pressure measurement module 6 and the received pressure signal. Further, the controller 3 may acquire the pressure center coordinate value and a time signal corresponding to the pressure center coordinate value, generate a pressure center coordinate time series based on the pressure center coordinate value and the time signal corresponding thereto, and generate a balance evaluation result according to the pressure center coordinate time series.

Alternatively, as shown in fig. 3c, N may also be 2, and the number of pressure sensors is 8. The number of pressure sensors may be determined based on the stiffness of the frame material at the bottom of the walker 2. When the material of the frame is rigid and does not deform or sag significantly during use, the solution shown in fig. 3a is sufficient. If the frame material has poor rigidity, the frame may be recessed due to the solution shown in fig. 3a, which affects the measurement accuracy of the pressure sensor. Therefore, the scheme shown in fig. 3b or fig. 3c can be selected, and the pressure sensors are symmetrically arranged below the rack, so that the pressure bearing capacity of the rack can be enhanced, and the measurement accuracy of the pressure sensors can be ensured.
