Be very specific that you want them to activly set limits for your return to guitar. Keep asking about those limits every time you go into the office. Many people just sit there and don't activly participate to get what they want, so the PT will likely jus run through their usual speal. Be spacific. This will help your PT anticipate your questions and so they will be better ready to provide you with this spacific need.

Good Luck, go get em Tiger.
