Description
Technical Field
[0001] This invention relates to the field of monitoring equipment technology, and in particular to a wearable motion monitoring device for Parkinson's disease. Background Technology
[0002] Parkinson's disease (PD) is caused by a decrease in dopamine neurons in the substantia nigra, leading to dopamine depletion in the striatum and causing symptoms such as movement disorders. Typical manifestations include resting tremor, rigidity, postural instability, and bradykinesia. The onset usually begins in one lower limb and gradually affects all four limbs. PD is generally classified into three subtypes based on the type of movement disorder: tremor, rigidity, and mixed type. The movement disorders in PD patients often cause them to have difficulty moving around, making it difficult for them to visit the hospital regularly and hindering doctors from timely monitoring of the patient's latest symptom changes.
