Description

External counterpulsation device for prevention and treatment of sarcopenia

technical field

The invention relates to sarcopenia prevention technology, in particular to the technology of using an external counterpulsation device to prevent sarcopenia.

Background technique

Sarcopenia is a disease characterized by decreased muscle volume, muscle strength, and physical function. In 2016, sarcopenia obtained the International Classification of Diseases (ICD-10) code (M62.84) provided by the World Health Organization, which indicated that sarcopenia was identified as a new disease. The prevalence of sarcopenia is about 10% in the elderly population in the community, as high as 50% in the elderly over 80 years old, and as high as 30-50% in the hospitalized elderly. Sarcopenia makes walking, sitting and other daily activities difficult for the elderly, increasing the risk of falls, disability and mortality.

At present, the prevention and treatment methods for sarcopenia are limited, mainly nutritional intervention + resistance exercise, and there are no effective prevention and treatment drugs. However, resistance exercise is difficult to implement for most elderly people, especially the elderly, nursing homes and hospitalized elderly. Whole body vibration (WBV) is a newly developed new technology for the prevention and treatment of sarcopenia, but this technology requires the elderly to stand continuously, so it is also difficult to implement for severe sarcopenia patients.

On the other hand, external counterpulsation (ECP) is a technology that has been used clinically for more than 40 years. There are many external counterpulsation devices available, but the past applications are mainly for the prevention and treatment of coronary heart disease, angina pectoris, congestive heart failure and ischemic heart failure. Complementary prevention and treatment of stroke. However, in recent years, studies have found that the average posterior tibial artery blood flow increased to (133±3.4)% of the base state 1h after ECP, which has the effect of improving peripheral blood circulation. The growth, repair, and work of skeletal muscle require the blood and oxygen supply of the capillary network. Studies have shown that the capillary network is sparse in sarcopenia and the microcirculation is impaired. Improving microcirculation may improve the muscle function of sarcopenia patients.
