Muscle Stimulator

What are the adverse reactions of deep brain electrical stimulation?

Deep brain electrical stimulation surgery is relatively mature. The intracranial condition of patients has been relatively stable one month after operation. After startup, some patients have symptoms such as dizziness, numbness of lower limbs, abnormal sound, hyperactivity and excitability. Through later parameter adjustment, the above adverse reactions gradually disappear within 3-6 months. Bleeding and infection are easy to occur 3-5 days after operation, with an incidence of about 1%. Patients who pass the risk period have less adverse reactions, mostly reversible adverse reactions. Because patients will be strictly evaluated before operation, most patients have less adverse reactions.

Transcutaneous electrical nerve stimulation is mainly used to treat pain caused by various causes, and can also be used to promote wound healing after operation. Its frequency is generally between 2-160 Hz, belonging to the low-frequency range. The pulse should be short or shorter, and the width is generally 9-350 Hz μ M. If the pulse is too wide, the fibers transmitting pain are activated, and the ions under the motor are activated, which may aggravate the pain.

The intensity is generally comfortable. You can choose to stimulate the afferent nerve response of proprioception without touching the efferent nerve response of movement. Current intensity varies in different forms. At present, there are double current or single current, bidirectional pulse and single wave direction. In addition, there is an asymmetric bidirectional pulse, and these methods can be used.
