Description

A kind of trunk muscle group flexion and extension strength training and testing seat and using method thereof

technical field

The invention belongs to the field of medical equipment, and relates to a trunk muscle group flexion and extension strength training and testing seat and a use method thereof.

Background technique

The trunk muscles include the lumbar extensors and flexors. As the main muscles for maintaining the uprightness and movement of the upper body, they are an important part of the core muscle group of the human body and play an important role in maintaining the dynamic balance of the lumbar spine and supporting and protecting the spine. With the advent of the information age, more and more jobs require us to sit in front of computers for long periods of time. Therefore, low back pain has almost become a common problem for office workers. Studies have shown that insufficient trunk muscle strength is related to the occurrence of chronic low back pain. Many people's understanding of low back pain is limited to terms such as lumbar disc herniation and lumbar muscle strain, but they do not understand the principle or how to exercise. Blindly training according to certain training methods may make the situation worse due to improper training or inappropriate training. The traditional trunk muscle strength training methods mainly include "flying swallow" training, straight leg raising training and plank support. Although it is convenient and convenient, there are many types, high movement requirements, and it is difficult to control the stretching range. People with low back pain often feel the waist after the first exercise. Soreness, discomfort, stiffness, etc. Some people use too much force and instead get sprained during exercise. For the elderly and people with osteoporosis, irregular movements may also lead to the risk of fractures. Although there are isokinetic training test training systems developed abroad, which can realize functional training and test evaluation of trunk muscles, but the machine is expensive, takes up a lot of space, and is complicated to operate, and is mainly used for scientific research; A step-by-step, simple, convenient, safe and comfortable integrated device for standardized low back muscle function training and testing.
