Thanks for all of the input! I have done quite a bit of research on the purpose and effects of the taping and I think it's fascinating! My son was taped for the first time just before a practice, so he could tell if there was a noticeable difference for him... He did feel a bit better with the tape; however, with so many variables involved, it's hard to say for sure yet whether it was just the tape that helped...
There are actually 3 different taping patterns for his particular problem, so the therapist is trying all of them to find which works best... My son just had his 2nd pattern done this morning and will throw some, over the weekend, to test it... He's also doing prescribed exercises at home each day and will begin ultrasound therapy on Monday...
I'll be sure to post about our overall experience with Kineseo taping, once all 3 patterns have been tried... If it's effective, I plan to have my son use it, proactively, from now on... I did find a good source for the tape, at a decent price, online, if anyone is interested!
