@bmcq I was prescribed SETb y my vascular surgeon and did find the program available at the KU, Kansas University Hospital unfortunately, that location was too far away from my home for me to attend. I was told that I can do the program on my own, The following is what I was provided as directed in order to attempt the SET on my own.
1. Start at a pace that lets you walk for 5-10 minutes before you start to feel claudication. This feeling is unpleasant, but doesn't hurt you. Keep going until the pain makes you feel like you need to stop.
2. Stop and rest for 3-5 minutes, just long enough for the pain to go away. You can rest standing or sitting.
3. Again walk at a pace that lets you walk for 5-10
minutes before you feel pain. This may be slower than your starting pace in step 1. Then rest again.
4. Repeat this process until you've walked for 45 minutes. This should be about 60-80 minutes total, including rest time. You may not be able to do a full 45 minutes at first. Do as much as you can, and increase your time as you improve.
Walk at least 3 times a week and wear shoes with sturdy flexible soles.

I hope this helps.
