Patients with Parkinson's disease usually have varying degrees of dyskinesia symptoms, clinically characterized by resting tremor, bradykinesia, muscle stiffness, and posture gait disorders. The resting tremor of Parkinson's patients is due to the multiple contraction movements of the upper limbs to the antagonist muscles. The tremor frequency is generally between 3 Hz and 9 Hz, and the tremor signal source is located in the neuronal activity network of the cerebral cortex. The occurrence of resting tremor in the upper limb not only affects the patient's physical posture, but also has a greater negative effect on the patient's daily living ability and quality of life.
