Unresponsive, odd walking

[Henry]

Hello, I bought three adult giant cave roaches for an experiment. I knocked them out with cold water and put electrodes in their rear legs. However, on waking up, two are sluggish and much less responsive, and one is having difficulty walking, and for a small period of time, convulsed some. Both had been less active even when I bought them. I did accidentally cause a puncture wound in the lower area of the body. Is it likely they will survive? 
also, please don’t hate. I did the experiment as ethically as possible. They felt no pain and I genuinely care for them and intend on keeping them as pets. They are well fed and watered
