Squash / Windowed Squash / Squish

Пит ван Дюзен не рекомендует использовать Windowed Squash на средней линии (C3 / Cz / C4), а также использовать разные диапазоны окна с левой и правой стороны (источник):

I had an unusual experience this morning with a client and am wondering if others have seen this. I was working with a women who has a lengthy trauma history, and this was our 3rd session, following our plan and looking for protocols that would help. We were doing a windowed squash at C3 and C4 (leaving out 12-20 on the left and 8-15 on the right) and for the first half of the session, perhaps 10 minutes, she was doing really well, and reported a slight decrease in anxiety and “ decrease in “racing in her mind”. Then, all of a sudden there was this tremendous activity, especially in the beta and hi-beta range at C4. She described this feeling of “all of a sudden I’m really stressed” as occurring frequently. She was not able to calm this activity down. We ended up doing some GSR and she said that “helped a little”. So what was that? Did she begin to relax and then it felt unsafe? Why didn’t it happen on the left side too? Thanks in advance for sharing your thoughts. Shelly

I don't like to do Windowed Squashes with different frequencies at the two sites, and I'm not real fond of doing them across the midline. What the design does is add the signals together, so you kind of smear the training band when you don't use the same one in both places. I'm guessing that you may actually have been allowing beta to increase at C4 (as you wished to do at C3) and alpha at C3 (as you wished to do at C4), and that may have felt like a major loss of control.
