I have the Edgelow Protocol kit and had that type of PT, my threapist made me a "home neck traction" thing-a-majig and I love to use it and listen to a meditation CD I got from the library.

First you get someone to help you loop the hand towel from the base of your neck to the top od your head- almost like a unicorn :P. Tie the towel into place up there then tape around the tie just to make sure its secure.
Next, connect the theraband to the towel loop so you have a chain.
Then, do the same with a rope, connecting it to the theraband.

How it all comes together:
The rope end goes on a door handle. Put your head in the towel end, with it around the base of your neck and the tied end close to your forehead/ hairline (think unicorn haha) then you sit down close to the door and slowly lay down. Scootching away from the door on your back until the chain gets taut and you begin to feel a pull through your neck. \
You can move away as much as you want. Also if your arms are too sensitive to fall to your sides, you can use a belt to loosely bind them in a folded arm, yet relaxed position across your belly. I listen to Jack Kornfield's Meditation for Beginners Disc 1 because it talks about pain a little bit.
The pull for me is such a relief. I feel my neck elongate and the feeling of compression goes away. My PT said its ok to do this for as long as you want too! I swear it is the best active thing I've done for discomfort throughout my TOS/ RSI experience and I recommend it wholeheartedly!

If this sounds like something you'd like to try and my explanation was too hazy, let me know. I'd be glad to post a picture of the traction thing and what it looks like in use.
