Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad invention. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
One symptom of intervertebral disease is a change in the mobility of the lumbar vertebrae. The spine consists of a plurality of parts, such as cervical vertebra, thoracic vertebra, lumbar vertebra, sacral vertebra, caudal vertebra and the like, and the mobility of each part of the spine is different, wherein the mobility of the cervical vertebra and the lumbar vertebra is large, the mobility of the thoracic vertebra is small, and the sacral vertebra and the caudal vertebra basically have no movement. The activity of lumbar vertebrae can be reduced due to various lumbar vertebra diseases, the accurate and reliable measurement of the activity of lumbar vertebrae is very necessary for evaluating the symptoms of the lumbar region and the treatment effect, and the examination of the activity of the vertebral column has clinical significance. If the mobility of the lumbar vertebra is reduced, pathological changes of the lumbar vertebra are indicated. The anatomical structure of the lumbar vertebrae is complex, making it very difficult to accurately measure the mobility of the lumbar vertebrae. Currently, there are few tools and methods for measuring the activity of the lumbar spine. There are also methods that rely on modern instrumentation, such as electromagnetic motion analyzers, ultrasonic three-dimensional motion analyzers, potentiometric measurements, and X-ray measurements, which are not only expensive, but also somewhat harmful to the body. None of the detection methods or instruments can detect the three-dimensional space activity of the lumbar vertebrae, so that the data obtained by measuring the detection methods or instruments cannot truly reflect the activity of the lumbar vertebrae. In the actual lumbar activity degree testing process, the lumbar action can drive the activity of sacrum and shank, and the motion of the relevant position of these lumbar vertebrae can make activity degree testing result be not conform to actual action value. Therefore, the accurate, reliable and easy-to-operate lumbar mobility measuring device is particularly important for clinical evaluation of lumbar function.
Fig. 1 is a schematic structural diagram of a device for detecting lumbar mobility according to an embodiment of the present invention. The detection device includes:
a first fixing device 10 configured to detachably fix a sacrum of a subject 20 to be measured on a test table 30;
a second fixing device 40 configured to detachably fix the leg of the subject 20 to the test table 30;
a sensor 50 configured to be detachably mounted on a chest position of the measured person 20, the sensor 50 being configured to detect first chest activity data of the measured person 20, wherein the first chest activity data includes at least one of: the front curve angle, the back curve angle, the left curve angle, the right curve angle, the left rotation angle and the right rotation angle of the chest; and
and an intelligent terminal 60 in communication connection with the sensor 50, wherein the intelligent terminal 60 is configured to obtain and display the activity of the lumbar vertebra of the measured person 20 according to the first chest activity data detected by the sensor 50, a coordinate transformation algorithm, and the relative position between the lumbar vertebra of the measured person 20 and the position coordinates of the sensor 50.
The sensor 50 may be at least one of: gyroscopes and goniometers. Such as a high precision nine axis gyroscope. The sensor 50 can be held in place on the chest of the person 20 by straps. The first chest activity data may further include at least one of the following angular velocities of movement: angular velocity of anterior curvature movement, posterior curvature movement, left curvature movement, right curvature movement, left rotation movement and right rotation movement of the chest. The inspection table 30 can be lifted to adjust its height.
The lumbar vertebra of the measured person 20 may include a plurality of vertebrae, i.e., a first lumbar vertebra, a second lumbar vertebra, and so on. For example, the lumbar spine of a human body includes five vertebrae, including a first lumbar vertebra, a second lumbar vertebra, a third lumbar vertebra, a fourth lumbar vertebra, and a fifth lumbar vertebra. The mobility of one lumbar vertebra of the subject 20 refers to the anterior curvature angle, posterior curvature angle, left curvature angle, right curvature angle, left rotation angle, and right rotation angle of any lumbar vertebra (e.g., the second lumbar vertebra).
Because the chest is a barrel-shaped structure consisting of the sternum, the thoracic vertebra and the ribs, the stability of the chest is good compared with the cervical vertebra and the lumbar vertebra. Sternum, thoracic vertebrae and ribs are ossified and connected, and the sternum and thoracic vertebrae are substantially immovable relative to the lumbar vertebrae. Therefore, when the waist muscle of the human body normally moves, the lumbar activity can be reflected on the current activity data of the chest connected with the lumbar activity, and the lumbar activity can be obtained by utilizing the chest activity data. The chest connected to the lumbar vertebrae can be regarded as a rigid extension of the lumbar vertebrae due to the small mobility. In the lumbar movement detection, when the subject 20 is assumed to perform the forward flexion movement, the change in the movement (for example, the change in the angle) of the chest is larger than the change in the angle of the lumbar vertebrae with respect to the vertical axis. Therefore, the motion data of the chest is easier to detect, and the detection sensitivity of the sensor is less required. In addition, if the sensor 50 is fixed to the lumbar vertebrae for detection, since the lumbar vertebrae generally include a plurality of vertebrae, such as a first lumbar vertebra, a second lumbar vertebra, and so on, the position intervals of the vertebrae of the lumbar vertebrae are relatively small. When the sensor is fixed, the sensor 50 cannot be accurately fixed to the lumbar vertebrae to be detected, for example, to the first lumbar vertebra or the second lumbar vertebra. Therefore, it is possible to avoid inaccurate detection of the activity of the lumbar vertebrae when the sensor 50 is fixed to the lumbar vertebrae.
Since the first chest motion level data is obtained as data in the coordinate system in which the chest of the subject 20 is located, it is necessary to convert it into the coordinate system in which the lumbar vertebrae are located. After the coordinate system is transformed, the motion of the lumbar vertebrae can be obtained based on the transformed first chest motion data and the relative position between the position coordinates of the lumbar vertebrae of the subject 20 and the sensor 50 in the same coordinate system.
The embodiment of the invention provides a detection device for the activity of lumbar vertebrae, which is characterized in that a sensor is used for detecting first chest activity data of a measured person, and then an intelligent terminal obtains the activity of one lumbar vertebra of the measured person according to the first chest activity data detected by the sensor, a coordinate transformation algorithm and the relative position between the position coordinates of one lumbar vertebra of the measured person and the sensor; compared with the traditional method of measuring for multiple times by adopting an angle measuring ruler, the method adopts the sensor to obtain the three-dimensional space activity, and is more convenient to operate; compared with manual reading, the reliability of data output by the sensor is higher; the problem that the activity of the lumbar vertebra cannot be accurately detected due to the fact that the sensor is not easy to be installed at the correct position when the sensor is fixed on the lumbar vertebra is also avoided; in addition, the motion data of the chest is easier to detect, so that the requirement on the detection sensitivity of the sensor is lower, and compared with the detection by directly installing the sensor on the lumbar vertebra, the detected data can be more accurate; the activity of the sacrum and the legs can be driven by the action of the lumbar vertebra, the activity of the parts can lead the activity degree detection result not to conform to the actual action value, and the sacrum and the legs of a measured person are fixed on the detection table by adopting the fixing device, so that the detection data of the activity degree is more accurate. The detection device provided by the embodiment of the invention solves the problem that the existing lumbar activity cannot be accurately detected, changes the situation that the activity of the lumbar of a human body is judged mainly by the experience of a doctor clinically, the judgment method is difficult to unify, and the measurement data is difficult to quantify, has an obvious guiding effect on clinical treatment of lumbar diseases, improves the treatment effect of the lumbar diseases from the side, greatly reduces the detection and treatment cost of patients with the lumbar diseases, and has a wide market application prospect.

Based on the anatomical posture, three mutually perpendicular axes, namely a sagittal axis, a coronal (frontal) axis and a vertical axis, can be set for the human body. The sagittal axis is a horizontal line in the front-back direction; the coronal (frontal) axis is a horizontal line in the left-right direction; the vertical axis is a vertical line which is vertical to the horizontal line in the vertical direction. The vertical axis, the sagittal axis and the coronal axis are generally used as coordinate system axes when expressing the position change of bones and joints. The sacral vertebrae are part of the biological spine and, in most mammals, include three to five sacral vertebrae. The sacrum of the human body is, from top to bottom, a first sacrum, a second sacrum, a third sacrum, a fourth sacrum and a fifth sacrum in sequence. The sacral position can refer to any sacral position.
The sacrum is positioned below the lumbar, and when the activity of the lumbar is detected, the sacrum basically has no activity, and the position basically does not change.
