Less, though, than when I opened the article; I have independently noticed my RSI worsens when stressed. Im not sure I buy the mumbo jumbo about the solution as much as I buy the explanation of why stress could affect it.
I use a powerball daily which has really helped. Saw the same issues with massage that the article writer had (short term fix) but it feels really great so I stuck with that=. But the powerball seems to really keep it in bay (I think it is the rotational stuff that helps).
When really stressed I do pull ups and press ups to stretch the relevant muscles.
