Description
Technical Field
The utility model belongs to the technical field of the gait analytical equipment, especially, relate to a portable gait analytical equipment.
Background
Gait analysis (gait analysis) is a technique for obtaining and analyzing gait parameters by observing or collecting the posture of a human body while walking. Gait is the subject technology of walking research, and is a comprehensive and scientific research on the lower limbs (feet, ankles, knee joints and hip joints) of a human body. Common gait parameters include spatial parameters (stride length, step size, step width, etc.), temporal parameters (stance/swing phase, single step time, step frequency, etc.), and the symmetry of the left and right feet of these parameters, the stability of long-term data, etc. Gait analysis plays a very important role in sports, medical rehabilitation and the like, and is widely applied and researched. Therefore, the utility model is a portable gait analysis device with simple structure, low cost, real-time gait parameter acquisition and rich and various acquired gait parameters, which has very practical significance;
the traditional gait analysis equipment and device are generally three-dimensional gait analysis instruments used in large hospitals and rehabilitation centers, and the equipment has the following defects: the device needs to occupy larger area, is specially installed, has high cost and inconvenient test and use, and the like. In recent years, with rapid development of scientific technology, miniaturization, low power consumption, stabilization of transmission data, and the like of sensor technology and wireless communication technology, some portable gait analysis device apparatuses have been used and developed. Most of the published patents use a single or a few sensors to acquire gait parameters, such as application numbers 201510539926.2, 201710013303.0, 201520586219.4, 201620354808.4, 201310105338.9, 201710207292.X and 201620811826.0, and only use a pressure sensor to acquire the gait posture parameters, so that the gait parameters acquired by the device are not rich enough, and particularly, the acquisition difficulty is high for the space parameters (such as step length, stride, step pitch and the like) of the gait. There are also those using a plurality of sensors, such as those of application nos. 201510971801.7, 201620811275.8, 201620679560.9, 201710060095.X, which employ both a pressure sensor and a 6-axis inertial sensor (three-dimensional acceleration sensor and three-dimensional gyro sensor), without a three-dimensional geomagnetic sensor. The three-dimensional geomagnetic sensor is very useful for calculation of gait parameters, particularly for calibration in the horizontal direction, otherwise the accuracy of gait data acquisition and calculation is affected. In addition, the utility model scheme that adopts multisensor, the technology degree of difficulty (the structure is complicated) and user's practicality of manufacturing are not considered in most designs, or the practicality is not good enough. For example, in application numbers 201620679560.9 and 201611015679.7, the motion sensors are respectively arranged at the tongue and the leg, the pressure sensors are arranged at the sole, the components are somewhat scattered, additional process design and routing are needed to complete, the structure is complex, and the process difficulty of production and manufacturing is increased. Like utility model No. 201520908440.7, 201520803403.X, place data acquisition control circuit in the heel position of shoe-pad, according to foot anatomy principle, human arch of foot position atress is minimum when normal walking, heel position atress is great, in the long-term walking use of user like this, the device is easily extruded for a long time by human gravity and is damaged, life shortens, the practicality is not good again, for example application No. 201611015679.7, 201610708083.9, dress the main part and dress the position in ankle department or shank, need additionally increase equipment technology (unlike shoes or shoe-pad, the user just needs originally, not the equipment that additionally increases), the practicality is not very good yet. For example, the device is applied to 201721286471.9, a film pressure sensor and an inertial sensor are used for acquiring step gait signals, for example, the device is applied to 201721302611.7, the film pressure sensor, the inertial sensor and a pickup sensor are used for acquiring the step signals in a fusion manner, and part of the gait signals are also intelligently acquired without lower limb signals above an ankle joint, such as a knee joint, a hip joint and the like. At present, individual wearable gait analysis devices are provided, lower limb signals of ankle joints, knee joints, hip joints and the like can be detected, but wired links are adopted among all sensors, the structure is complex, and much inconvenience is brought to practical use.
In conclusion, the conventional portable gait parameter acquisition and gait analysis device has the problems of poor practicability, complex structure, insufficient acquisition of parameters and the like.
