I'm Michelle (the girl in the video). This thread is really fascinating to me. I'll add some more details to the discussion below. I was diagnosed with epicodylitis (tennis albow) and I tried a range of different treatments: electrical therapy, accipunture, anti-inflammatory tablets and some kind of light therapy(?) But without any results (probably why I can't remember the last treatment).
Also notised there were some questions about neck pains, If I adjust the nose-pad to the right level and angle it right it forces me to sit up straight. However, in the video my back is arched quite a lot because I was sitting at a table that was too low (but it was only a temporary setup).
