Abstract:
Spastic hypertonus (muscle over-activity due to exaggerated stretch reflexes) often develops in stroke and spinal cord injury (SCI) survivors and individuals who suffer from multiple sclerosis. In previous published experiments we have shown that Direct Current (DC), when used to lesion nerves, can attenuate muscle force in a gradual manner, and this attenuation can last for several months. In this paper we present initial experimental results that profile the current required to cause controlled nerve ablation.
