I agree with chuck - to me the roller has been one of my best tools for making the recovery come along.
It is a challenge the first week or so, but afterwards it's a palpable relief to me.
I used and still sometimes do use the bands. I particularly liked one exercise that I did in outpatient PT (4 weeks+):
- Tie a band around the bottom of a chair leg, one of the back two.
- Slip your foot in until the band is around your ankle so you're facing towards the back of the chair. Keep close to the chair in all of these
- Keeping your leg straight, pull back until a good amount of resistance.
- Repeat a good number of times. I started with five, went to ten.
- turn to your right 90 degress, both feet parallel, your left side to the back of the chair.
- Now move your foot sideways, keeping the leg straight for n repetitions to resistance.
- Turn right again 90 degrees, facing away from the chair.
- Holding on to the back of the chair, move your foot forwards, keeping your leg straight for n repetitions.
- One more 90 degree right turn, this time your right is sideways to the back of the chair.
- Pull the foot across the front of your leg, stop at the proper resistance. Repeat n times.
- And you're done...
Now I started this after about five weeks and had no restrictions except 50 lbs carrying and no impact sports. Check your restrictions and make sure this plays well with them.
Make sure you're comfortable, always hold on to the back of the chair, if you need to step over the band to be in the best position, do so.
It is a very gentle exercise, but really addresses the small muscles both on the supporting leg and the moving leg. I still do them periodically to see if I am strong in all directions. Preventative in my part.
Eventually, once you are a pro with one band, you can either use another with more resistance or use two in a loop. That wasn't until about six or seven months for me. I don't think you want to over stress this, just get them strong enough to do well.
