Well, if he is willing to self-experiment, we could start immediately with an “n = 1” experiment: just him, one person. This is pretty simple to do:
1- Start with the initial prognosis. What has he tried, what was the outcome, what have his physicians told him is left for him to try, anything? What percentage chance do they give him of a recovery. Getting full records at this point is critical, because when PEMF starts to work, people naturally begin to forget just how desperate and hopeless they had become before trying PEMF.
It is very helpful to collect any quantitative data that is available at the outset such as blood tests, photographs and measurements of wounds, anything that gives a quantifiable record of the starting point before using PEMF.
Then, once he has gotten his initial prognosis and his records, and especially if doctors are willing to put statements into writing stating how dire the outlook is, then you begin using PEMF.
Then the fun begins (it is usually fun, especially if PEMF starts to work, which it often does). Have him keep a daily journal: what he did, how he used the PEMF system: where, how long, what settings, as many details as possible.
Record any personal observations, such as reduction of pain, restoration of feeling or function, reduced wound seepage or noticeable healing.
Then, keep detailed records of any doctor visits and comments and lab test results during this process.
Since he has several major issues, he might start working on one area, and if it really helps, he may want more ICES-PEMF systems to cover more different locations at the same time. If it is not working in an area (give it 2-3 weeks), then move on to the next area to try and record the observations, details of use, outcomes, etc.
Then, at some point in a few moths he will have a lot of information, we can collect it, maybe write a paper, and report the results here to help other people.
This approach does not change the world on one swoop, but it has helped many people, one-by-one, and if the record keeping is good, we gain a lot of information from each person who does this.
