Hey EJ, sorry to hear you took a fall, not having full use of your hands when dealing with this can make things real complicated without some help especially when you add your leg issues into the mix….
When I lost the use of my right arm this last time, when at home I fell back on the Kins cloth Pullons, doubled up at night with the plastic pants to keep things dry. It was relatively easy to pull things together! When headed out with a Supreme or Mega Max I found by placing the diaper on the toilet seat (At Home!) then sitting in it and pinning the back against the tank while I kind of twisted my body to get things reasonably tight then fastened as tight as I could using my left hand & pre-pealing tapes before climbing in!
I can’t say I won any awards for the end results, but at least by covering all with the Kins taffeta pants kept things together and water-tight for the most part!
Good luck Buddy, hope your feeling better soon!
