Does artificial electrical stimulation restore muscle size & function in atrophied fibres following denervation?

 

Artificial electrical stimulation is the use of device which sends gentle electrical pulses through the skin, they also help in repairing of muscles and also transcutaneous electrical nerve stimulation helps to reduce pain. When muscle fibers are denervated, they are shrunken and angular and they stain darkly with oxidized enzymes, also a fiber becomes progressively more atrophic until it ultimately appear as a clump of pyknotic nuclei without any myofibrillar material. It is true that artificial electrical stimulation will restore muscle size and function, this is because this electrical stimulation stimulation delays reinnervation in denervated muscle and both reinnervation and electrical stimulation can counteract loss of muscle excitability as well as muscle atrophy. And as we know larger muscle mass leads to better functioning of denervated muscles. Additionally, this artificial electrical stimulation is important in muscle because they restore muscle strength and also reduce muscle atrophy.
