The first thing to do is listen to them. The interpreters who report symptoms are the ones who know the symptoms best. After how much time, and after what kind of meeting, are they most likely to experience them? So you have to start by listening to the interpreters when they report symptoms.
I also believe that adjustments can be made. As my colleague was saying earlier, more research has to be done. Obviously, adjustments can be made, for example regarding their working time and their work environment. Again, it takes a bit of research to determine this exactly.
We are looking for a miracle solution or a technological miracle, but my feeling is that there isn't one. I would tend to try to understand the situation and the factors that generate these kinds of symptoms and try to adjust the situation so the interpreters do not have the symptoms.
I don't know whether that answers your question.
