Day 122 - Nerve Stimulation (24/01/2018)

Nothing much to report in the morning, we wrapped up the CBL case and decided we really needed to be more efficient next time. While we liked our normal way of doing things, it really wasn't compatible with the complexity of neurological cases and we need much more structure to be sure.

In the afternoon, things got a lot more lively. We had an optional lab on nerve conduction testing, which involved taking an electrode and using it to stimulate nerves running deep to the skin, then watching the resultant muscle twitches. It's quite unsettling, having your muscles move against your own conscious will.

We were able to elicit a variety of movements using various placement positions, controlling different fingers or even making my entire wrist turn and clench. We could also adjust the frequency and intensity of the electrical stimulation such that we were able to mimic both a benign essential tremor and the sorts of tremors that would be seen in Parkinson's disease - the latter was very uncomfortable indeed.

We ended up going a bit off-piste and stimulated the muscles of my face directly - against the advice of the lab supervisors, I should add. It was funny to be fair and you get very visible responses, such as lip twitches or rapid eye movements. Let's hope there are no serious long-term consequences.
