Hi Moosey-
I coined that BLAST term some years back after being in recovery and nurses were saying I should remember BLT for no bending, lifting, twisting..... "Oh, and also remember not to Stretch" I was told. I said, then the acronym is not complete! Told them make it BLAST for no bending, lifting, stretching, and twisting......

Add "log roll" to that, and you are fixed for surgery. Log roll is the method for arising from and returning to bed so as to avoid hurting self more, and to minimize risk of messing with the installed spinal cord stim works.
I hope all goes well for you,
