Cervical vertebra rehabilitation and health care training aiding system

Abstract

The invention discloses a cervical vertebra rehabilitation and health care training aiding system, which comprises a headband and a computer, wherein a three-axis acceleration sensor, a microcontroller and a signal transmission module are arranged on the headband; the microcontroller collects three axial acceleration signals and sends the three axial acceleration signals to the computer through the signal transmission module; the computer receives the acceleration signals and transmits the acceleration signals to a cervical vertebra rehabilitation and health care training application program inside; the application program builds a virtual object for simulating head movement, utilizes information technology to build a virtual cervical vertebra training environment and preset an efficient and interesting training mission, i.e. presets mouse or keyboard movement corresponding to the movement of the virtual object in a two-dimensional space or a three-dimensional space, and drives the virtual object to move correspondingly according to mouse or keyboard movement converted by the three axial acceleration signals. Meanwhile, the application program judges whether the head movement meets a preset training mission requirement or not in real time according to acceleration information, and if not, a text, voice and / or picture prompt is displayed.

Description

technical field [0001] The invention relates to the field of cervical spine rehabilitation and health care, in particular to a computer-aided training system for cervical spine rehabilitation and health care. Background technique [0002] With the popularization of computers, the proportion of cervical spondylosis is increasing year by year. Existing cervical spine rehabilitation products, some have single function, and some have complex design. The two most commonly used ones are: one is to use a camera to capture head images, identify head movements through image processing, and image processing methods to identify moving objects. The purpose of detection is to extract the moving parts in the background. In the process, it will be affected by factors such as light brightness gradients in the surrounding environment and small noise interference, resulting in detection errors. The difference in the core image processing algorithm also has a lot of influence on the results. ...

Existing cervical spine rehabilitation products, some have single function, and some have complex design. The two most commonly used ones are: one is to use a camera to capture head images, identify head movements through image processing, and image processing methods to identify moving objects. The purpose of detection is to extract the moving parts in the background. In the process, it will be affected by factors such as light brightness gradients in the surrounding environment and small noise interference, resulting in detection errors. The difference in the core image processing algorithm also has a lot of influence on the results. , and image acquisition is affected by distance, camera resolution, etc., the recognition resolution and accuracy of subtle movements, spatial displacements and angles are not high, there must be no occlusion between the camera and the recognition target, and the recognition target must be within the shooting range of the camera to be recognized Recognition, target activity range is limited, the system is complex and inconvenient to use; the other is to detect head movements through sensors, such as the patent document CN102178535A discloses a cervical spine fun health care system and its implementation method, using two-axis acceleration to collect two directions The acceleration and gyroscope determine the angular velocity of the third axis. This method uses two sensors at the same time: the acceleration sensor and the gyroscope, and the hardware structure is more complicated.

Moreover, this method qualitatively judges six real-time motion postures of neck movement, and only six specified neck movements can be set during program setting. The training method is relatively simple, and it is only used in the field of neck health care.

The above shows that the existing methods need to be improved
