Repetitive nerve stimulation in myasthenia gravis

Myasthenia gravis, repetitive nerve electrical stimulation showed that when low-frequency electrical stimulation (3 ~ 5Hz), the amplitude decreased by more than 15%; When high frequency electrical stimulation (above 10Hz), the amplitude decreases by more than 30%. Repeated electrical stimulation examination is the main examination method to detect neuromuscular junction diseases. This examination should be carried out 12-18h after stopping neostigmine, otherwise false negative results can occur. 90% of myasthenia gravis patients were positive under low-frequency stimulation, which was related to the severity of the disease.

The complications of spinal cord electrical stimulation therapy are generally less, including bleeding, hematoma, local infection, epidural hematoma and infection, cerebrospinal fluid leakage, lead displacement, hardware disorder, unexpected stimulation, pain at the implantation site, skin ulceration, rejection reaction, etc. The main indications of spinal cord electrical stimulation therapy are the treatment of back surgery failure, complex local pain, adhesive arachnoiditis, postherpetic neuralgia, peripheral ischemic pain, limb pain, peripheral neuropathic pain, angina pectoris, pain after spinal cord and nerve injury, etc. patients with successful stimulation can have a high-quality life.
