Abstract

The invention discloses a monitoring system for human motion. The system comprises a signal generator, a laser, a first conduction optical fiber, a sensing optical fiber, a second conduction optical fiber, a photoelectric detector, a signal demodulation processor and a wearing device; the signal generator is connected with the laser through a circuit and used for generating a demodulation signal so as to drive the laser to output a laser pulse signal; the sensing optical fiber is a flexible sensing optical fiber, the wearing device can be worn on the movable joint of the human body, and the sensing optical fiber is fixed to the wearing device and can be bent and deform along with joint motion of the human body. According to the monitoring system for the human motion, the motion characteristics of all movable joints of the human body can be accurately reflected and monitored, and quantitative evaluation can be conducted. The motion characteristics have extremely important value on evaluation for dyskinesia diseases such as Parkinson's disease and fremitus.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a human body motion monitoring system. Background technique [0002] Parkinson's disease (PD) is a disease caused by selective degeneration and loss of dopamine neurons in the substantia nigra pars compacta, gliosis, neuronal α-synuclein (α-Syn) deposition and Lewis Idiopathic neurodegenerative disease characterized by the appearance of corpuscles (LB). Characteristic movement disorders such as tremors, bradykinesia, and gait abnormalities occur due to the lack of dopamine neurons. It is estimated that there are approximately 10,000,000 people with Parkinson's disease in the world, and this number is growing. There are about 60,000 new cases in the United States each year. The prevalence of Parkinson's disease among people over 65 years old in my country is about 1.7%, and there are currently at least 3,000,000 patients. After deep brain stimulation (DBS) is applied t...
