However, to the best of our knowledge, there have been no studies Stimulator microsystems have been rapidly developed and used in Spinal cord of a rat is stimulated ( 25). That electrical stimulation can improve cognitive deficitsĪssociated with traumatic brain injury ( 24), and that low-frequencyĮlectroencephalogram (EEG) signals appear when the sub-paresthesia Shown that patients with spinal cord injury can achieve standingĪnd walking ( 21– 23). General, electrical stimulation of nerves is an efficient approachīy implanting an electrical stimulator, studies have Nerve stimulation system for chronic hemiplegic shoulder pain. Safety and efficacy of a fully-implantable axillary peripheral Shoulder pain who received a fully-implanted electrical stimulatorĪnd were followed up for 24 months the study demonstrated the Wilson et al ( 17) studied patients with hemiplegic

NeuromuscularĮlectrical stimulation is effective in the short term in improving Of the brain, and physical care is time intensive. However, prolonged use of drug treatments may affect other regions Motor ability in the lower limbs using certain treatments ( 8, 9, 14, 15). Shown that it is possible for patients with hemiplegia to regain Stimulation ( 9– 12), and implanted nerve electrical Is generally treated with drugs ( 5, 6) such asĪcetyl glutamine and amantadine, physical therapy ( 7), general nursing methods ( 8), transcutaneous electrical nerve Hemiplegia is generally a symptom of stroke (when aīleed or blood clot damages part of brain) and brain injury, and it The results indicated that electrical stimulation of the sciatic nerve can activate the motor region of the rat brain, and provided evidence that stimulation of the sciatic nerve could be a method of preventing motor cortex degeneration.ĭegeneration of the cortex is commonly found withīrain injury ( 1), stroke ( 2), limb amputation ( 3) and aging ( 4). This phenomenon was identical in both young and old rats. It was found that at the frequency band of 8‑16 Hz, the EEG signal in the right motor area was higher than at other frequency bands. The results showed that when the sciatic nerve was stimulated by the implanted electrical stimulator, motor‑related channels were activated, causing contraction of the left leg. The relationship between sciatic nerve stimulation and brain activity was analyzed. The sciatic nerves of Sprague‑Dawley rats (sorted into old and young groups) were stimulated by the electrical stimulator under anesthesia, and the EEG signal was recorded simultaneously.
The study is based on a self‑developed fully implantable nerve electrical stimulator and a self‑developed multi‑channel electroencephalogram (EEG) electrode array. The present study investigated whether electrical stimulation of the sciatic nerve can activate the motor‑related area of the brain. Currently, there are no ideal means of treatment, other than medication and sports rehabilitation. Functional degradation of the motor cortex usually results from brain injury, stroke, limb amputation, aging or other diseases.
