Parkinson's Disease (PD), also known as parkinsonism syndrome, parkinsonism, is a chronic degenerative disorder of the central nervous system, which is common to the elderly, with an average age of about 60 years, and recent years of which the age of onset has a decreasing trend, in our country, it is counted that the incidence of PD is 1.7% in people over 65 years, 1% in people over 55 years, PD has become the "third killer" for the middle aged and elderly, severely threatening the life health of humans.
At present, no good method for treating parkinsonism and other cerebral nervous system diseases exists in clinic, and even no effective method can relieve the development of the diseases and can only be developed at will. At present, patients can only exercise by themselves, exercise strides and walking to relieve and reduce the development speed of the diseases.
Patients with parkinson's disease have been reported to improve walking ability, such as stride gain, with the aid of visual cues, such as black stripes attached to the floor. However, this solution has the following drawbacks and disadvantages:
firstly, attaching continuously spaced strips to the floor is inconvenient, unsightly on the one hand, and the patient must walk along the path of the attached strips, limiting their freedom. On the other hand, is not suitable for environments outside the home such as communities.
Secondly, the technical proposal can not improve the walking ability of parkinsonism patients, which comprises the steps of increasing stride, increasing pace and expanding the range of motion. Because the walking ability to be improved is different for different patients and parkinsonian patients of different layers, the quality of life and satisfaction of the patients cannot be improved.
