My 79 year old father's back was broke at L2-4 levels over 30 years ago. In the past 11.5 weeks he's endured 3 surgeries to try to relieve his back pain. 8 hours to fuse L3-L5, remove 30 yr old broken rods above that, 3 hours 2.5 weeks later to cement in the screws holding the new rods that had loosened up (brittle bones). And finally 2 days ago 1.5 hours to cement a cracked vertebrea around L3. Paralysis for those few months many years ago had taken it's toll on his leg muscles anyways, but now after mostly laying in bed for 3 months he's lost almost 40 pounds (not a bad weight for him to be at) and is so weak. A bad experience at aqua therapy about a month ago, unable to get stood up in the locker room, and the pain he continues to endure have kept him away from any formal therapy. Today he sat at the kitchen bar height table for a bit and was to weak to get stood up from that position. My 77 year old 125lb mother had to let him lean over her back to get back to bed. That experience has completely upset him, not only about his situation but he's afraid she is going to get hurt. Where do I go from here? Any meal plans to help him build the strength to be able to stand? Best exercises anyone has found you can do in bed to strengthen his thighs? Any suggestions?
