Device and method for detecting freezing gait of patient suffering from Parkinson's disease

Abstract

The invention provides a device and method for detecting the freezing gait of a patient suffering from a Parkinson's disease. The device comprises a first inertial node, a second inertial node, an inertial node synchronizer, a pressure insole, a mobile terminal and a wireless Bluetooth headset. The first inertial node and the second inertial node are used for acquiring accelerated speed data, angular speed data and magnetic force value of the left leg and the right leg of the patient; the inertial node synchronizer is used for enabling the two inertial nodes to be in a synchronous mode; the pressure insole is used for acquiring pressure data of feet of the patient; and the wireless Bluetooth headset is used for giving audio stimulation on the patient when the patient has freezing gait to assist in the patient to recover normal gait. The method comprises the steps of real-time freezing gait detection, audio feedback and information recording. The device is simple in structure, and is light and convenient, a person wears the device conveniently, the device has good sensitivity and specificity, the freezing gait of the patient can be automatically detected and evaluated so that the patient can be protected in time, and the device can help a specialist physician to formulate a rehabilitation plan.

Description

technical field [0001] The invention relates to the fields of sensing technology, biomedical engineering, medical care and sanitation, and in particular to a device and method for detecting frozen gait of Parkinson's disease patients. Background technique [0002] Parkinson's disease (Parkinson's Disease) is a common neurodegenerative disease, clinical symptoms include resting tremor, muscle rigidity, bradykinesia and postural balance disorder motor symptoms and hyposmia, sleep disturbance and depression and other non-motor symptoms. Freezing of gait (FOG) is a gait disorder characterized by recurrent short-term gait hysteresis. It often occurs in the middle and late stages of Parkinson's disease. Unable to step smoothly when encountering obstacles, the feet seem to be frozen on the ground, at the beginning of the start or when turning, you must step on the spot several times, wait for a few seconds or minutes before you can walk forward in small steps, or drag forward for s...

However, the sensitivity and specificity of the above-mentioned laser walking aid device disclosed above are not particularly high, and misjudgment will inevitably occur. When misjudgment occurs, the device emits laser light, which is likely to interfere with the patient's sight, and is very likely to Cause the opposite effect, interfere with the normal walking of the patient, and cause unnecessary danger
