Balance Evaluation Device

technical field

The utility model relates to the field of medical equipment, in particular to a balance evaluation device.

Background technique

Human balance ability is an important physiological function, which is the basic ability to ensure that human beings can maintain stable standing, walking, and complete complex movements. Balance is divided into static balance and dynamic balance. Static balance refers to the ability of the human body or a certain part of the human body to maintain a stable state when it is in a certain posture, such as sitting or standing. Dynamic balance includes various voluntary movements of the human body and the ability of the human body to maintain a stable state after external disturbances. Patients with balance dysfunction need training to restore their balance. Through balance training, postural reflexes can be stimulated, and the stability of the vestibular organ can be strengthened, thereby improving balance function.

Most of the devices currently on the market for balance assessment and training are balance board equipment. The gait balance test is to let the patient walk a short distance on the balance board, but limited by the length of the balance board, it is not possible to carry out the gait balance test and training continuously for a long time, and corresponding adjustments cannot be made according to the degree of illness of the patient.

Most of the traditional balance testing equipment is a balance board. Due to the length of the balance board, patients cannot continue to perform gait balance evaluation and training for a long time. Moreover, the traditional balance board cannot make corresponding adjustments according to the degree of illness of the patient.

In order to solve the above problems, an embodiment of the present application discloses a balance evaluation device, including: a number of pressure measurement modules, which are dispersedly arranged at the bottom of the balance evaluation device, and the pressure measurement modules are used to measure the balance of the object to be measured. The pressure signal generated during the evaluation process; the controller is connected to each of the pressure measurement modules for receiving the pressure signal, and the controller is also configured to: obtain the balance evaluation parameters of the balance evaluation device, and the balance evaluation The parameters include evaluation speed and evaluation time; using the balance evaluation parameters, a balance evaluation result is generated.

Exemplarily, the main structure of the balance assessment device may be a walking machine or a treadmill, or a device similar to a walking machine. As shown in FIG. 1 , the present application takes the walking machine 2 as the main body of the balance evaluation device for description. Wherein, the pressure measurement 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 can also be arranged outside the walking machine 2 .

Optionally, the controller 3 may acquire balance evaluation parameters through a data input device. For example, the balance evaluation device can be a human-computer interaction module 1, and the controller 3 can be connected to the human-computer interaction module 1. The user inputs the evaluation speed and evaluation time through the human-computer interaction module 1, and the human-computer interaction module 1 will evaluate the evaluation speed and evaluation time. The time is sent to controller 3.

Optionally, the human-computer interaction module 1 is also used to receive the body data of the subject to be measured, and transmit the body data of the subject to be measured to the controller 3; the controller 3 The balance evaluation parameters are calculated; wherein, the physical data includes: age data, height data and injury grade.

Specifically, as shown in FIG. 1 , the human-computer interaction module 1 is arranged on the upper part of the walking machine 2 . The human-computer interaction module 1 may include a human-computer interaction panel, and a touch display screen is arranged on the human-computer interaction panel. The user can input the physical data of the subject to be measured by touching the touch screen, such as height data, age data or injury level. The human-computer interaction module 1 sends the body data to the controller 3, and the controller 3 calculates balance evaluation parameters according to the body data of the subject to be measured.

After obtaining the balance evaluation parameters, the controller 3 uses the balance evaluation parameters to generate a balance evaluation result. Specifically, the controller 3 can generate a control instruction according to the balance evaluation parameters, and send the control instruction to the walking machine 2, control the walking machine 2 to run the evaluation time at the evaluation speed, and perform the balance evaluation on the object to be tested. During this process, the pressure measurement module 6 can measure the pressure signal generated by the subject to be measured during walking, and send the pressure signal to the controller 3 . 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, while the controller 3 obtains the pressure center coordinate value, it can also obtain the time signal corresponding to the pressure center coordinate value, and generate a pressure center coordinate time series based on the pressure center coordinate value and its corresponding time signal, according to the A time series of coordinates of the center of pressure can generate balance measures.
