Description

Core muscle group training chair

Technical Field

The invention relates to a core muscle group training chair in the field of medical rehabilitation instruments.

Background

In recent years, as more and more workers need to work in offices for a long time, such people are in a sitting state for a long time and lack corresponding exercises, and lumbago is easily caused for a long time. Lumbago refers to pain and discomfort in the area below the rib, above the gluteal transverse line and between the midlines of the side armpits, often accompanied by pain in the thighs. Lumbago is a common clinical disorder, which can seriously affect work ability and quality of life. Therefore, in order to reduce the occurrence probability of lumbago, along with the propagation of healthy life concepts, more and more people start running, yoga and other national fitness projects, but due to lack of specialized rehabilitation training guidance, the lumbago is aggravated after exercise training; coarse training patterns are poor patient compliance, incorrect training often results in poor therapeutic effects, and the like.

The core muscle group (core muscles) refers to the muscle group responsible for spinal stabilization, supporting the spine, and mainly includes rectus abdominis, transverse abdominis, oblique extraabdominis, erector spinae, multifidus, and thoracolumbar fascia. A large number of clinical studies abroad and domestically show that the condition of the core muscle group is closely related to the progress of chronic lumbago; the training of the nuclear cardiac muscle group can obviously improve chronic lumbago symptoms and lumbar vertebra functions and reduce recurrence.

At present, foreign clinical training modes comprise freehand training, elastic band resistance training, instrument training and the like. The training modes are to train target muscles according to the need, and the muscles or muscle groups are trained in a targeted mode by designing different actions, so that the training mode has a certain training effect, but omits the integral training of lumbar nucleus and cardiac muscle groups. The traditional mode has high requirement on manpower, on one hand, manual measurement and evaluation has higher requirement on subjective judgment capability of doctors, and on the other hand, one doctor can only guide one patient one by one at a time, and the requirement of the current rehabilitation crowd can not be met. Secondly, the training process is relatively boring and is easy to cause the burnout emotion of the patient. Finally, the training intensity and the training effect are difficult to evaluate, the physical condition of the patient changes along with the continuous progress of rehabilitation, the activity and the activity intensity are changed, and the traditional method has limited capability of recording and storing process data of the patient in the training process.
