[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0011] like Figure 1-2 As shown, this embodiment provides a balance ability testing device, which includes a fixed base 1, a six-degree-of-freedom motion platform 2 fixed at the bottom of the fixed base 1, a perforation at the top of the fixed base 1, a motion bearing platform 3 covering the perforation placed on the top surface of the fixed base 1, a pressure sensing plate 4 with multiple pressure sensors for monitoring changes in the center of pressure when the patient stands fixed on the top of the motion bearing platform 3, the pressure sensors on the pressure sensing plate 4 being arranged in a matrix, the top of the six-degree-of-freedom motion platform 2 having a perforation and being fixed to the bottom of the motion bearing platform 3, and so on. A transparent protective wall 5 is fixed around the top surface of the fixed base 1 along the motion support platform 3. Protective handrails 6 are fixed on opposite sides of the inner wall of the protective wall 5, arranged parallel to each other and on the same horizontal plane. A step 7 is fixed along the height of the fixed base 1 on its outer side, with handrails 8 fixed on both sides of the step 7. A protective door 9 is opened on the side of the protective wall 5 near the step. The tops of the two handrails 8 are fixed to the protective wall 5 and located on either side of the protective door 9. A servo driver 10 for driving the six-degree-of-freedom motion platform is also fixed inside the fixed base 1. The six-degree-of-freedom motion platform 2 adopts an existing structure.

[0012] This testing device also includes a VR headset 11 for displaying the gaze target. The VR headset 11 has a built-in camera for monitoring changes in the patient's eye opening and closing and a posture sensor (not shown in the figure) for monitoring changes in the patient's posture. The camera is an infrared camera, and the posture sensor is a 9-axis posture sensor. The VR headset 11, infrared camera, posture sensor, servo driver 10, and pressure sensor are all connected to a host computer 12. The specific communication connection method between the VR headset 11, infrared camera, posture sensor, servo driver 10, and pressure sensor and the host computer 12 is prior art, and the VR headset 11, infrared camera, posture sensor, servo driver 10, and pressure sensor all adopt existing structures.

[0013] When in use, the balance ability testing device is activated and initialized. The patient prepares by first putting on the VR headset 11, then stepping onto the stairs 7, opening the protective door 9, standing on the pressure-sensing plate 4, and then closing the protective door 9. The host computer 12 then starts the test, which has six testing modes.

[0014] First test mode: The host computer 12 controls the VR headset 11 to display the gaze target. The patient keeps their eyes open throughout the test. Simultaneously, the servo driver 10 drives the six-degree-of-freedom motion platform 2 to a static and stable state. That is, the six-degree-of-freedom motion platform 2 is not working at this time. The patient remains standing for 1 minute. During this process, the infrared camera monitors the changes in the patient's eye opening and closing within 1 minute and transmits the monitored eye opening and closing change signals to the host computer 12 for display. At the same time, the posture sensor monitors the changes in the patient's posture within 1 minute and transmits the monitored posture change signals to the host computer 12 for display. Simultaneously, the pressure sensor plate 4 monitors the changes in the center of pressure of the patient while standing within 1 minute and transmits the monitored center of pressure change signals to the host computer 12 for display. In the first test mode, the patient uses vision and proprioception to adjust their balance. Staff can see the changes in the center of pressure (COP) and posture of the patient in the open-eye state in the first test mode on the display screen of the host computer 12. Based on the changes in the center of pressure (COP) and posture, staff can analyze the patient's balance ability. The first test mode is a baseline test used to establish the standard of balance ability under normal conditions. If balance problems are shown under this condition, that is, poor balance ability, it indicates that there may be other non-sensory factors affecting balance, such as muscle strength or coordination problems.

[0015] The second testing mode: The host computer 12 controls the VR headset 11 to display the gaze target. The patient keeps their eyes closed throughout the test. Simultaneously, the servo driver 10 drives the six-degree-of-freedom motion platform 2 to a static and stable state. The patient remains standing for one minute. During this time, an infrared camera monitors the patient's eye opening and closing changes within one minute and transmits the monitored eye opening and closing change signals to the host computer 12 for display. At the same time, a posture sensor monitors the patient's posture changes within one minute and transmits the monitored posture change signals to the host computer 12 for display. Simultaneously, a pressure sensor tablet 4 monitors the changes in the center of pressure (COP) of the patient while standing within one minute and transmits the monitored center of pressure change signals to the host computer 12 for display. In this second testing mode, the patient uses proprioception and vestibular sense to regulate their balance. The staff can see the changes in the center of pressure (COP) and posture corresponding to the patient's closed-eye state on the display screen of the host computer 12 in the second testing mode. Based on these changes in COP and posture, the staff analyzes the patient's balance ability. In the second test mode, the eyes are closed to shut down visual input in order to assess the contribution of proprioception and the vestibular system. If the balance ability is poor under this condition, it may mean that the balance function of proprioception or vestibular system is impaired. If the balance ability is good under this condition, it means that the patient's proprioception and vestibular system functions are good at maintaining their own balance.

[0016] The third testing mode: The host computer 12 controls the VR headset 11 to display the gaze target. The patient keeps their eyes open throughout the test. Simultaneously, the servo driver 10 drives the six-degree-of-freedom motion platform 2 to vibrate. The patient remains standing for one minute. During this time, an infrared camera monitors the patient's eye opening and closing changes within one minute and transmits the monitored eye opening and closing change signals to the host computer 12 for display. At the same time, a posture sensor monitors the patient's posture changes within one minute and transmits the monitored posture change signals to the host computer 12 for display. Simultaneously, a pressure sensor tablet 4 monitors the changes in the center of pressure (COP) while the patient is standing within one minute and transmits the monitored center of pressure change signals to the host computer 12 for display. In this third testing mode, the patient uses vision, proprioception, and vestibular sense to regulate their balance, with proprioception playing a dominant role. Staff can see the changes in the center of pressure (COP) and posture corresponding to the patient's open-eye state in the third testing mode on the display screen of the host computer 12. Based on these changes in COP and posture, staff can analyze the patient's balance ability. In the third test mode, proprioceptive input is interfered with to further evaluate the role of proprioception. If the balance ability is poor under this condition, it may indicate that the proprioceptive balance function is impaired. If the balance ability is good under this condition, the patient's proprioceptive ability to maintain their own balance is good.

[0017] Fourth Test Mode: The host computer 12 controls the VR headset 11 to display the gaze target. The patient keeps their eyes closed throughout the test. Simultaneously, the servo driver 10 drives the six-degree-of-freedom motion platform 2 in a vibration state. The patient remains standing for one minute. During this time, an infrared camera monitors the patient's eye opening and closing changes within one minute and transmits the monitored eye opening and closing change signals to the host computer 12 for display. At the same time, a posture sensor monitors the patient's posture changes within one minute and transmits the monitored posture change signals to the host computer 12 for display. Simultaneously, a pressure sensor tablet 4 monitors the changes in the center of pressure (COP) while the patient is standing within one minute and transmits the monitored center of pressure change signals to the host computer 12 for display. In this fourth test mode, the patient uses proprioception and vestibular sense to regulate their balance, with the vestibular sense playing a dominant role. The staff can see the changes in the center of pressure (COP) and posture corresponding to the patient's open-eye state in the fourth test mode on the display screen of the host computer 12. Based on these changes in COP and posture, the staff analyzes the patient's balance ability. In the fourth test mode, visual input is excluded while proprioceptive input is interfered with to examine the function of the vestibular system. If the performance is poor under this condition, it may mean that the vestibular balance function is impaired. If the balance ability is good under this condition, the patient's vestibular system has a good ability to maintain its own balance.

[0018] Fifth Test Mode: The host computer 12 controls the VR headset 11 to display a gaze target accompanied by moving interference stripes around the target. The patient keeps their eyes open throughout the test. Simultaneously, the servo driver 10 drives the six-degree-of-freedom motion platform 2 to remain stationary and stable. The patient stands for one minute. During this time, an infrared camera monitors the patient's eye opening and closing changes within one minute and transmits the monitored eye opening and closing change signals to the host computer 12 for display. At the same time, a posture sensor monitors the patient's posture changes within one minute and transmits the monitored posture change signals to the host computer 12 for display. Simultaneously, a pressure sensor tablet 4 monitors the changes in the center of pressure (COP) of the patient while standing within one minute and transmits the monitored center of pressure change signals to the host computer 12 for display. In the fifth test mode, the patient uses vision, proprioception, and vestibular sense to regulate their balance, with vision playing a dominant role. Staff can see the changes in the center of pressure (COP) and posture corresponding to the patient's open-eye state in the fifth test mode on the display screen of the host computer 12. Based on these changes in COP and posture, staff can analyze the patient's balance ability. The fifth test mode assesses the importance of visual input to balance. Poor performance under this condition may indicate excessive visual dependence or a problem with the visual-vestibular system. Good performance under this condition indicates that the patient has a good ability to maintain their own balance visually.

[0019] The sixth test mode: The host computer 12 controls the VR headset 11 to display a gaze target with accompanying interference stripes moving around it. The patient keeps their eyes closed throughout the test. Simultaneously, the servo driver 10 drives the six-degree-of-freedom motion platform 2 in a vibrating state. The patient remains standing for one minute. During this time, an infrared camera monitors the patient's eye opening and closing changes within one minute and transmits the monitored eye opening and closing change signals to the host computer 12 for display. At the same time, a posture sensor monitors the patient's posture changes within one minute and transmits the monitored posture change signals to the host computer 12 for display. Simultaneously, a pressure sensor tablet 4 monitors the changes in the center of pressure (COP) of the patient while standing within one minute and transmits the monitored center of pressure change signals to the host computer 12 for display. In the sixth test mode, the patient uses proprioception and vestibular sense to regulate their balance, with the vestibular sense playing a dominant role. The staff can see the changes in the center of pressure (COP) and posture corresponding to the patient's closed-eye state in the sixth test mode on the display screen of the host computer 12. Based on these changes in COP and posture, the staff analyzes the patient's balance ability. In the sixth test mode, proprioceptive input is provided while visual interference is turned off to assess the vestibular system's ability to maintain balance. If the performance is poor under this condition, it may mean that the vestibular system is severely damaged. If the balance ability is good under this condition, the patient's vestibular system has a good ability to maintain its own balance.

[0020] This invention introduces a controllable six-degree-of-freedom motion platform to interfere with the patient's visual input. The six-degree-of-freedom motion platform can simulate vibration, providing the patient with rich proprioceptive stimulation. Simultaneously, a wearable VR headset is used to provide visual stimulation, thus interfering with the patient's visual perception. The VR headset's built-in camera, posture sensor, and pressure-sensing tablet for standing position are used to collect real-time and accurate data on the patient's physical responses under different sensory input conditions, providing this data to staff for analysis of the patient's balance ability.
