Best of luck, SRS.
After two days of wrestling w PT admin and insurance, I booked two aquatic PT appointments for a tuneup of my pool routine, and for setting current limits.
Today I spent an hour moving 250 pounds of hardscape via scooter, neatening up sewer dig pieces in prep for Lawndude work later today in that area. It was about 20 lifts of varying degrees of weight (5-60lbs) and how situated. I used PT directionality prescribed Tuesday for all lifts, and rested in between. Counts as 1/2 hour PT. One chunk of sharp-edged concrete scraped/cut my leg, but the only one I dropped on my toes was about 20 pounds... and it landed just right. (I was wearing my panic button in case I tipped the scooter, etc.)
A cotton shoelace can lift at least 60 pounds.
