Abstract
Description
Technical Field
[0001] The present invention relates to the field of wearable rehabilitation treatment for Parkinson's disease, and particularly to a wearable Parkinson's disease treatment monitoring device and its usage method. Background Art
[0002] Parkinson's disease is a common neurodegenerative disease. Its main pathological change is the degeneration and death of dopamine neurons in the substantia nigra of the midbrain, resulting in a significant decrease in dopamine content in the striatum and causing the disease. Clinically, it is mainly manifested as resting tremor, bradykinesia, muscle rigidity, and postural gait disorders, and is accompanied by non-motor symptoms such as depression, constipation, and sleep disorders. Drug intake and diet regulation are of great significance for controlling the condition and alleviating symptoms. Levodopa is a long-term oral drug for Parkinson's disease, but its dosing window is narrow, and the drug efficacy shows a weakening trend in the later stage. Therefore, it is crucial to customize the intake dose and regimen. Tryptophan is one of the important raw materials for synthesizing neurotransmitters. The products of its kynurenine metabolic pathway are closely related to the pathogenesis of Parkinson's disease. Appropriate intake of tryptophan helps to improve the function of the nervous system. Therefore, during the rehabilitation treatment process of Parkinson's disease patients, real-time monitoring of the amino acid and drug content in the patient's body, and timely warning of drug intake and diet therapy are crucial for the treatment of patients and assisting doctors in formulating targeted diagnosis and treatment plans.
[0003] Currently, the non-invasive wearable devices under research for Parkinson's disease mainly focus on the mechanical monitoring of motor symptoms and electrotherapy stimulation devices, and there is a relative lack of monitoring for high-throughput drug molecules and biotin. The existing sensing devices are mainly centralized monitoring based in hospitals, and the devices have bottleneck problems such as huge volume, high price, inconvenient to carry, poor human compliance, and long detection time, seriously interfering with the quality of life of patients and being unfavorable for doctors to give reasonable drug administration and diet therapy plans.
