Electrical stimulation system for suppressing Parkinson resting tremor based on skin reflex principle

Abstract

The invention discloses a surface electrical stimulation system for suppressing Parkinson resting tremor based on a skin reflex principle, which comprises a myoelectricity signal acquisition module, a myoelectricity signal pre-treatment module, a signal analysis and control module, a myoelectricity stimulator module and a stimulation electrode module connected in sequence, wherein the myoelectricity signal acquisition module comprises a recording electrode formed by a positive electrode sheet and a negative electrode sheet and a reference electrode. Electrical signals of the muscle are monitored in real time through the electrode sheets attaching to the skin surface of forearm muscle, the acquired myoelectricity signals are computed and analyzed via the signal analysis and control module, and frequency feature values of the myoelectricity signals are detected. Once the detected frequency feature values exceed preset frequency feature values with Parkinson resting tremor, the system drives the myoelectricity stimulator module to carry out electrical stimulation therapy on a patient timely, thereby achieving the purpose of suppressing upper limb tremor. The system of the invention is a portable wearable device, automation and intelligence can be realized during a rehabilitation process, the operation is simple, control is easy, and the operation is safe and reliable.

Description

Technical field [0001] The invention relates to the field of medical devices, discloses an electrical stimulation system for inhibiting Parkinson's resting tremor based on the principle of skin reflection, and expounds the principle and design scheme of the system for the first time. Background technique [0002] Parkinson's disease (abbreviated as PD), also known as tremor paralysis, is one of the most common neurodegenerative diseases, which is more common in the elderly. Its clinical manifestations mainly include dyskinesia, muscle rigidity, resting tremor, abnormal posture and gait. The resting tremor of Parkinson's patients is caused by the alternating contraction of multiple pairs of antagonistic muscles in the upper limbs. The frequency of the tremor is generally between 3-9 Hz. The source of the tremor signal is located in the neuronal activity network of the cerebral cortex. [0003] At present, the main treatment for Parkinson's disease is medication and surgery. In the...

In the early stage of the disease, the drug can improve the symptoms very well, but the limitation is that it must be taken for a long time. Once the treatment is stopped, the condition will recur, and after long-term use, the effective time of the drug will gradually shorten, and the side effects of the drug also make the drug Treatment options are extremely limited
