Description

technical field [0001] The invention relates to the technical field of rehabilitation medical equipment, in particular to a height-adjustable lower limb rehabilitation mechanical leg. Background technique [0002] As of 2017, the number of elderly people over the age of 60 in the country exceeded 240 million, and it is expected to exceed 300 million in 2025. With age, the probability of carrying chronic diseases such as cardiovascular and cerebrovascular diseases increases. Every year, there are 1.2 to 1.5 million new stroke patients, 800 to 1 million deaths, and about 75% of the survivors are disabled, resulting in poor limb function. The number of handicapped patients has increased correspondingly, and they have basically lost the ability to walk, including a large number of retired soldiers. According to the data provided by the World Health Organization, tens of millions of people are injured or disabled due to traffic accidents every year, and a large number of sudden ...
