[0040] The following is a description of the motor function assessment system provided in this application.
[0041] As shown in Figure 1, an embodiment of the motion function assessment system provided in this application includes a force bar unit 10, a pressure detection unit 20, and a calculation unit 30. The force bar unit 10 is used to detect the user's fine motor information, which includes at least one of the following when the user operates the force bar unit 10: twisting angle, twisting speed, grip strength, and pinching force, reflecting the user's fine motor ability. The pressure detection unit 20 is used to detect the user's gross motor information, which includes at least one of the following when the user is standing or moving: foot force information, gait information, and joint movement information, reflecting the user's gross motor ability when standing or moving. The force bar unit 10 and the pressure detection unit 20 are connected to the calculation unit 30 via wireless transmission methods such as Bluetooth, WIFI, and 5G. The calculation unit 30 is used to acquire the fine motor information sent by the force bar unit 10 and the gross motor information sent by the pressure detection unit 20, and to evaluate the user's fine motor ability and gross motor ability based on the fine motor information and gross motor information. For example, the calculation unit 30 determines the user's fine motor skills by using fine motor information to determine the user's movement trajectory and the force applied to the hand during a rotation. The calculation unit 30 can also determine the user's gross motor skills by using gross motor information to determine the user's posture, balance, and endurance when standing or walking. Therefore, by combining fine and gross motor skills, a more comprehensive assessment of the user's motor function can be conducted, improving assessment accuracy. This method is suitable for assessing the motor function of children with special needs (e.g., children with autism or cerebral palsy) or rehabilitation patients.
[0042] In one embodiment, the force measuring rod unit 10 includes a force measuring module and a second encoding module connected via communication. The force measuring module is used to measure fine motion information and includes multiple sensors (e.g., a six-axis sensor, a pressure sensor, etc.). The second encoding module may include an encoder corresponding to each sensor, used to encode the fine motion information before sending it to the computing unit 30. By encoding the data before sending it to the computing unit 30, the data format can be standardized and the data volume compressed, thereby improving data transmission and processing efficiency. The second encoding module can also encrypt the fine motion information before sending it to the computing unit 30 to improve the security of data transmission.
[0043] In one embodiment, as shown in Figures 2 and 3, the force-measuring rod unit includes a first force-measuring rod 11, which comprises a first rotating body 111, a second rotating body 112, an elastic element 113, and a first six-axis sensor 114. The radii of the first rotating body 111 and the second rotating body 112 are adapted to the user's hand size, thereby facilitating the user's grip on the first rotating body 111 and the second rotating body 112. The first rotating body 111 and the second rotating body 112 are connected by the elastic element 113, which provides a reaction force when the first rotating body 111 and the second rotating body 112 rotate. Under the action of the elastic element 113, the first rotating body 111 and the second rotating body 112 can rotate in the same direction or in opposite directions, thereby measuring the force information when the user performs a rotational action. The first six-axis sensor 114 is located inside the first rotating body 111 and is used to measure the rotational speed, rotation angle, and spatial position of the first rotating body 111. Alternatively, the first six-axis sensor is located inside the second rotating body 112 and is used to measure the rotational speed, rotational angle, and spatial position of the second rotating body 112.
[0044] For example, the first force-measuring rod 11 is first placed on the mechanical support to perform self-calibration, thereby determining the initial rotation angles of the first rotating body 111 and the second rotating body 112. When the user holds the first rotating body 111 and the second rotating body 112 with both hands and rotates them respectively, the first six-axis sensor 114 measures the rotational speed, rotation angle, and spatial position of the first rotating body 111 or the second rotating body 112. This allows for the determination of the torsional angle and twisting speed of the user's rotational action, as well as the spatial range in which the user performs the rotational action. Consequently, the process of the user performing the rotational action can be better reconstructed, leading to a better analysis of the fine motor skills of the user's hands during the rotational action. Therefore, by setting the first six-axis sensor 114 within the first rotating body 111 or the second rotating body 112, more comprehensive data on the user's rotational actions can be collected to better assess the user's fine motor skills, such as finger coordination and sensitivity.
[0045] It is understood that in other embodiments, the first force measuring rod 11 may also include a second six-axis sensor. The first six-axis sensor 114 and the second six-axis sensor may be located in the first rotating body 111 and the second rotating body 112 respectively, so as to simultaneously measure the rotational speed, rotational angle and spatial position of the first rotating body 111 and the second rotating body 112.
[0046] In one embodiment, the first force measuring rod 11 further includes an acceleration sensor located within the first rotating body 111 or the second rotating body 112 to measure the movement speed of the first force measuring rod 11 when the user performs a rotational action. By combining the movement speed of the first force measuring rod 11 when the user performs a rotational action, the fine motor skills of the user's fingers can be better assessed.
[0047] In one embodiment, as shown in FIG4, the first force measuring rod 11 further includes a pressure detection membrane 115 embedded in the surface of the first rotating body 111 and / or the second rotating body 112. Multiple pressure detection membranes 115 can be used to detect the user's grip strength. Exemplarily, marked areas are provided on the surface of the first rotating body 111 and / or the second rotating body 112. When the user places their hand in the marked area, the pressure detection membrane 115 can detect the hand's grip strength and also detect the force distribution of each finger when the user grips the first rotating body 111 or the second rotating body 112. By providing the pressure detection membrane 115 on the first rotating body 111 and / or the second rotating body 112, the testing functions of the first rotating body 111 and the second rotating body 112 can be enhanced.
[0048] The first force measuring rod 11 also includes a first power supply component 116 and a first charging interface 117 connected to each other, so that the first force measuring rod 11 can be used after charging to meet the needs of various scenarios. The first force measuring rod 11 also includes a switch button 118, so that the device can be turned on or off according to user needs. The first force measuring rod 11 also includes a status indicator light to indicate the working status of the first force measuring rod 11. For example, when the user turns on the first force measuring rod 11 through the switch button 118, the status indicator light is green, and when the user rotates the first rotating body 111 or the second rotating body 112, the status indicator light is yellow. The first force measuring rod 11 also includes a first microcontroller 119, which is used to preprocess the data collected by the first six-axis sensor 114, the second six-axis sensor, and the pressure detection membrane 115 (e.g., remove abnormal data, unify the time of the first six-axis sensor 114, the second six-axis sensor, and the pressure detection membrane 115, etc.) before sending it to the computing unit 30.
[0049] In one embodiment, as shown in FIG5, in the first force measuring rod, the accelerometer, the first power supply assembly 116, and the first microcontroller 119 are located inside the first rotating body 111. The first six-axis sensor 114, as well as the pressure detection diaphragm 115, the analog-to-digital converter chip, and the encoder inside the first rotating body 111, are all connected to the first microcontroller 119. The analog-to-digital converter chip is used to encode the data collected by the pressure detection diaphragm 115 on the first rotating body 111 and send it to the first microcontroller 119. The encoder is used to encode the rotational speed and rotational angle of the first rotating body 111 and send it to the first microcontroller 119. In the second rotating body 112, the pressure detection diaphragm 115, the analog-to-digital converter chip, and the encoder are all connected to the first microcontroller 119. The analog-to-digital converter chip is used to encode the data collected by the pressure detection diaphragm 115 on the second rotating body 112 and send it to the first microcontroller 119. The encoder is used to encode the rotational speed and rotational angle of the second rotating body 111 and send it to the first microcontroller 119.
[0050] In one embodiment, as shown in Figures 6 to 8, the force-measuring rod unit 10 includes a second force-measuring rod 12. The second force-measuring rod 12 includes a force-measuring rod body 121, a knob rotatably mounted on the force-measuring rod body 121, and a rotating measuring component located within the knob. The force-measuring rod body 12 and the knob are adapted to the user's hand size, facilitating the user's grip on the force-measuring rod body 12 and rotation of the knob. The knob can rotate clockwise or counterclockwise on the force-measuring rod body 12. The rotating measuring component can be an encoder, located within the knob, used to collect information such as rotation direction, rotation speed, and rotation distance when the user rotates the knob. The rotation distance can be the number of rotations, thereby enabling the determination of rotation speed and rotation angle when the user performs a rotational action, further determining the user's finger dexterity.
[0051] In one embodiment, there are two knobs, namely a first knob 122 and a second knob 123. The two knobs are different in size and are respectively adapted to an encoder that collects the rotation direction and rotation distance. This allows the knobs to adapt to the dexterity requirements of different fingers, thereby meeting the motion assessment needs of users of different ages.
[0052] In one embodiment, the second force measuring rod 12 further includes a pinch force detection element 124 located on the force measuring rod body 121. The pinch force detection element 124 includes a gravity sensor for detecting pinch force when the user's finger presses the pinch force detection element, thereby enabling the second force measuring rod 12 to detect more comprehensive hand movement information.
[0053] In one embodiment, the second force measuring rod 12 further includes a protective cover 125 sleeved on the pinch force detection element 124, which can protect the pinch force detection element 124 and extend the service life of the pinch force detection element 124.
[0054] In one embodiment, the second force measuring rod 12 further includes a third six-axis sensor 126 located inside the force measuring rod body 121. The third six-axis sensor 126 is used to detect the spatial position and movement speed of the second force measuring rod 12, thereby collecting the spatial position and movement speed of the user when performing rotational movements. Combining the spatial position and movement speed of the user when performing rotational movements can improve the accuracy and consistency of the collected fine movement information.
[0055] In one embodiment, the second force measuring rod 12 further includes a second power supply component 127 and a second charging interface 128 connected to each other, so that the second force measuring rod 12 can be used after charging to meet the needs of various scenarios. The second force measuring rod 12 also includes a switch button, so that the device can be turned on or off according to user needs. The second force measuring rod 12 also includes a status indicator light to indicate the working status of the second force measuring rod 12. For example, when the user turns on the second force measuring rod 12 through the switch button, the status indicator light is green, and when the user rotates the first knob 122 or the second knob 123, the status indicator light is yellow. The second force measuring rod 12 also includes a second microcontroller 129, which is used to preprocess the data collected by the rotating measuring component, the pinch force detection element 124 and the third six-axis sensor 126 and then send them to the computing unit 30.
[0056] In one embodiment, as shown in FIG9, the rotation measuring device includes a first rotary encoder and a second rotary encoder. The first rotary encoder is located inside the first knob 122, and the second rotary encoder is located inside the second knob 123. The third six-axis sensor 126, the second power supply assembly 127, the second microcontroller 129, the pinch force detection element 124, and the analog-to-digital converter chip are all located inside the force measuring rod body 121. The pinch force detection element 124 is connected to the analog-to-digital converter chip, and the first rotary encoder, the second rotary encoder, the third six-axis sensor 126, the second power supply assembly 127, and the analog-to-digital converter chip are all connected to the second microcontroller 129.
[0057] It is understood that the force measuring rod unit may include only the first force measuring rod 11, or only the second force measuring rod 12, or both the first force measuring rod 11 and the second force measuring rod 12, to adapt to different measurement needs.
[0058] In one embodiment, the pressure detection unit 20 includes a pressure detection pad 21 and a motion detection sensor 22 mounted above the pressure detection pad 21.
[0059] The pressure detection pad 21 is used to detect foot force and gait information when a user stands or moves on it. Gait information can be the landing points of the two feet. For example, when a user stands, steps forward, moves laterally, or moves in other directions on the pressure detection pad 21, the pressure detection pad 21 determines the user's foot force and gait information based on the landing points of the user's feet and the force distribution on the pressure detection pad 21. For example, a foot force heatmap can be determined based on the force information detected by the pressure detection pad 21 at various parts of the foot. The calculation unit 30 can display the foot force heatmap on a display screen.
[0060] In one embodiment, as shown in FIG10, the pressure detection pad 21 includes a pad body 211 and a matrix pressure sensing membrane 212 disposed in the pad body, thereby collecting pressure data of different parts of the foot through the high-density sensing points in the matrix pressure sensing membrane, which improves the accuracy of the detection data.
[0061] The pressure detection pad 21 also includes a control board 213 connected to the matrix pressure sensing membrane 212 and a communication device (e.g., a Bluetooth connection device) 215 connected to the control board 213 via a connection cable 214. The control board 213 transmits the pressure data collected by the matrix pressure sensing membrane 212 to the computing unit 30 via the communication device 215. The pressure detection pad 21 also includes a power interface 216 located on the communication device 215 and connected to the control board 213. The power interface 216 is connected to an external power source to power the control board 213. The pressure detection pad 21 also includes a pressure detection pad switch 217 located on the communication device 215 and connected to the control board 213, allowing the user to turn the pressure detection pad 21 on or off as needed. The pressure detection pad 21 also includes a waterproof membrane 218 covering the matrix pressure sensing membrane 212, thereby protecting the matrix pressure sensing membrane 212 and extending the service life of the pressure detection pad 21.
[0062] In one embodiment, as shown in FIG11, the pressure detection pad 21 includes a sensing module and a Bluetooth module. The sensing module includes a matrix pressure sensing membrane 212 and a control board 213 connected for communication. The Bluetooth module includes a Bluetooth connection device, which is connected to the control board 213 via a USB data cable, thereby sending the pressure data collected by the control board 213 to the computing unit 30. The control board 213 is connected to an external power source to power the Bluetooth connection device and the matrix pressure sensing membrane 212.
[0063] As shown in Figure 12, the motion detection sensor 22 is used to detect joint movement information when the user is standing or moving. For example, when the user stands or moves on the pressure detection pad 21, the motion detection sensor 22 synchronously tracks the movement trajectory of different joints throughout the user's body. Exemplarily, the motion detection sensor includes a lidar scanner, which has a higher response speed and stronger anti-interference capability, improving the accuracy of the detection data.
[0064] By combining foot force information, gait information, and joint motion information, information such as the user's balance, weight transfer ability, and coordination when standing or moving can be determined. This allows for a more comprehensive and accurate assessment of the user's movement status, thereby improving the accuracy of gross motor function assessment.
[0065] In one embodiment, the pressure detection unit 20 further includes a control box 23 connected between the pressure detection pad 21 and the motion detection sensor 22. The control box 23 can power the pressure detection pad 21 and the motion detection sensor 22, and can also perform data calibration and time synchronization on the pressure detection pad 21 and the motion detection sensor 22 to improve the accuracy of the detected data.
[0066] In one embodiment, the pressure detection unit 20 further includes a first encoding module communicatively connected to the pressure detection pad 21 and the motion detection sensor 22. The first encoding module can be integrated into the control box 23, or into the pressure detection pad 21 or the motion detection sensor 22. The first encoding module encodes coarse motion information and sends it to the computing unit 30, thereby unifying the data format with the computing unit 30, compressing data volume, and improving data transmission and processing efficiency. The first encoding module can also encrypt the coarse motion information before sending it to the computing unit 30 to improve data transmission security.
[0067] The computing unit 30 can be a server, or a terminal device such as a mobile phone, tablet computer, or desktop computer. It can also be partially located on the server and partially on the terminal device, or it can be integrated into the force measuring rod unit 10 or the pressure detection unit 20.
[0068] In one embodiment, the computing unit 30 is also used to output evaluation prompts, enabling the user to operate the force bar unit 10 or the pressure detection unit 20 according to the evaluation prompts, thereby supporting the smooth progress of the evaluation task and ensuring the collection of correct data. For example, the computing unit 30 outputs instructions to hold the first force bar 11 or the second force bar 12 and rotate it, and then collects the fine motion information sent by the first force bar 11 or the second force bar 12. The computing unit 30 outputs prompts to stand at a specified position on the pressure detection pad 21 or complete a specified movement on the pressure pad, and collects the gross motion information sent by the pressure detection pad 21 and the motion detection sensor 22.
[0069] In one embodiment, the computing unit 30 includes a display screen for displaying fine motion information and coarse motion information when the user operates the force bar unit 10 and the pressure detection unit 20, so that the tester can view the collected data in real time.
[0070] In one embodiment, the computing unit 30 is further configured to determine a training task suitable for the user based on the user's fine motor skills and gross motor skills, and display it on the display screen. For example, the computing unit 30 stores a preset training evaluation model. By inputting the user's fine motor skills and gross motor skills information into the evaluation model, the user's fine motor skills and gross motor skills can be obtained from the evaluation model output. At the same time, the computing unit 30 can also output a training task suitable for the user, thereby facilitating the user to train according to the training task.
[0071] For example, the workflow of the motion function assessment system provided in this application embodiment is as follows: The calculation unit 30 establishes a communication connection with the force bar unit 10 and the pressure detection unit 20 (via Bluetooth, 5G, WIFI, etc.) based on the user's start command. Then, it outputs assessment prompts based on the user's assessment command, and the user operates the force bar unit 10 and the pressure detection unit 20 sequentially according to the assessment prompts. While the user operates the force bar unit 10 and the pressure detection unit 20, the calculation unit 30 acquires the fine motor information collected by the force bar unit 10 and the gross motor information collected by the pressure detection unit 20, and displays them on the screen. Simultaneously, it assesses the user's fine motor ability and gross motor ability based on the fine motor information and gross motor information, and outputs a training task based on the assessment results, which is also displayed on the screen.
