Apply get in and get out, don't let anything follow your record further. You're not out at this point. Keep pressing forward to your goal.
Physicians have had blunders in their past, so have PT's too. Know your mistake and own it to improve from here on out. You'll likely do alright.
You don't have a felony on your record and you've mentioned it's expunged. It could be substantially worse off.
This will come up to report likely even though expunged during licensing and possibly due to the big-brother-like reporting of even arrest records that show up in background checks for clinicals. But your case will not bar you from admittance or future career... Learn from your mistake and move forward. Run a background check on yourself when the time comes, and possibly know how laws in your current state affect your situation.
I've talked to researchers who've looked into these topics regarding PT licensing and background checks. You're not alone. Keep your nose clean from here on out and move forward.
Lastly, don't get any further convictions or even arrests. It's not worth playing with your future any more. Young and stupid /= (not equal) disbarment in your case. Make sure who you were then are not who you are now.
Good luck!
