Description

Portable balancing capability testing device with dynamic and static conversion function

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a human body balance ability detection training device.

Background

Balance capability refers to the ability to maintain body position, particularly the ability to control the center of gravity of the body on a small support surface. Balance ability is the basic ability of all static and dynamic activities of humans. Any movement of a person is almost always performed in a state of maintaining body balance, which is influenced by a number of factors, which compensate and interact with each other. The balance capacity is taken as a basic capacity of a human body, plays a very important role in the daily life of normal people, and especially for old people or people suffering from certain diseases, the balance capacity is measured and known in advance, so that the method is favorable for early warning of certain diseases and targeted training. For example, the fall of the old can be early warned in advance, and the occurrence of the fall can be reduced by performing corresponding training.

The existing balance capacity detection equipment is mainly divided into two types of static balance and dynamic balance. The static balance detection is based on a plantar pressure sensor, so that the balance capacity of a person in a static non-disturbance condition is measured, and the test precision is limited. To increase the test accuracy, a tester is usually required to perform specific test actions, such as standing on a single foot, closing the eyes, squatting, and the like, and the procedure is relatively complicated. In addition, the static balance detection equipment is difficult to realize recovery training for people with poor balance ability because motion is difficult to generate. The detection platform of the dynamic balance detection equipment can automatically generate disturbance after a human body stands, the balance capacity is measured by evaluating the capacity of a person to be detected to control the human body so as to reduce the disturbance amplitude, and the relative test precision of the type of the test equipment is higher. Meanwhile, the dynamic balance detection equipment has the characteristic of free disturbance, so that rehabilitation training corresponding to the balance capacity can be realized through the setting of a specific action curve and a program.

At present, no matter dynamic balance and static balance tests are carried out, other testing equipment except for simple plantar pressure testing plate type testing equipment is mainly fixed equipment, and movement is inconvenient. Especially for dynamic balance testing, the equipment is relatively heavy and inconvenient to move. The simple plantar pressure test board without the armrests can only perform simple static balance test, and for the old, the old is easy to fall down in the test process due to the fact that the armrests are not arranged. In view of this, some devices are currently provided with a split armrest, the armrest and the device are separately arranged, the armrest part can be moved and arranged at will during the test of the device, the device is acceptable for static balance test, but for dynamic balance test, the change of the relative position can cause interference to the test result, and the separately arranged dynamic balance test is not seen at present. And for the evaluation of the balance capability of the community old people and each old service or physical examination mechanism, a portable test device with higher precision and function can be provided so as to adapt to the measurement of the transferability of the community or moving at any time, so that the purchase cost of the device can be greatly saved, and different test results have better consistency and comparability.
