The way I see it is you are talking about collecting and analysing data to measure the effectiveness of a methodology.
Lets use caffeine as an example:
I was told by another pwp that caffeine can be helpful when worn off; I tried it using coffee and found it worked and then experimented with it by adding sugar which is absorbed in the duodenum as is levodopa. I have considered other effects like gastric emptying and also the impact of caffeine on circulation of the blood.
So I have taken something that was known and effectively through trial and error fine tuned it.
I have passed this on to other pwp but only very few have adopted it but those that have had success.
I also checked out caffeine (usually coffee but sometimes energy drinks, which by the way have other ingredients that may be beneficial) with my neuro, he was aware of it and said was ok. I would also advise caffeine can have detrimental effects on the body so check out with your gp if in doubt.
So I have taken a known solution (not widely known and adapted it to my needs and found it very beneficial. Those that have adopted it have had success too. The process of doing this also highlighted the importance of other factors that cause wearing of and / or stop the pills from working. So effectively looking at the solution to one problem has uncovered others.
I believe that this warrants further study; trialling it with other pwp to gauge the effect ie research. PWP researcers could help with this.
Its something that is simple to do and effective and that can be implemented immediately.
Technology can be a great help but do we need an app for everything we do. Keep it simple.
A device to tell us we are in danger of falling I guess works in the same fashion as a car parking detector but its only as good as the driver is in using it. What we need is to develop better mobility skills to aid us when we walk and learn to use devices like walking sticks etc.
Its a team effort, medical professionals, carers, charities but it must involve the patient because pwp hold the key to the information science needs.
I dont see how you can calculate the timings of your levodopa based medicine when it is complicated by so many other factors such as other drugs, metabolism, the effect of sleep etc
Why would you need to, we have the best sensory detector, analyser and implicator our own brains. They may be flawed as pwp but they still work. I dont need an app to tell me Im wearing off or falling asleep in the car my own senses tell me its what you do about it thats critical.
I feel more emphasis should be placed on learning what your body already can tell you and from that develop the devices we need that allow us to implicate the changes.
My opinion, maybe not yours but I wish you success and the fact that you are making an effort is great and I applaud you for that. We both may be wrong or right but if you dont try you dont find out.
