Ajai, I forgot to say that even though your father is in pain, there are gyms that have trained coaches, who can adapt gentle exercises for your father. My daughter and son-in-law own a gym and I go there. I first went to the YMCA but the leaders weren't certified and didn't know how to adapt anything. Personally, speaking from experience, I would start with gentle stretches and walking on the treadmill. The stretching gently stretches the muscles, which relaxes them. Relaxed muscles don't hurt as much. So the splinting muscles start relaxing, layer by layer. Now this doesn't mean that the primary pain is gone, but it does mean that the muscles around the spine don't hurt, which cuts down on the overall pain. Since I belong to the "been there, done that" club, stretches should be done next to a wall or with the back of a chair to hold on to if balance issues crop up. The treadmill is wonderful because there are build in handles, the speed is adjustable, and the "path" is smooth to walk on. Do wear a good supportive pair of sneakers, make sure there is a wide toe box so there is room for his feet to swell a bit. This is natural. Now having a 97 year old father-in-law, I know all the arguments against going to the gym, against stretching, against walking. There will be enough excuses to fill a book. Excuses don't help. Excuses get you nowhere. Yes, your father is 85 and in pain. I am 69 and when I started in the gym, I was in remission from polymyalgia rheumatica and my muscles were like marshmallows. My back hurt so much I wasn't sure I could do any of it. I decided that I wanted to be able to play with my grandchildren, to do everything I used to do. I worked very hard, my muscles hurt the next day, but I kept going. The first day, I walked out of the gym on "spaghetti legs" and finally climbed into the car. Then I realized that I had a clutch. Sounds stupid, but I was so overwhelmed that I wasn't sure I could push it in. I drove the three miles home, climbed the 6 steps in the house and sat on the couch for two hours. I was dripping sweat, but couldn't move because I wasn't at all sure I could stand up in the shower. Each day it got easier at the gym. One minute exercises than 30 seconds to rest, get a drink, mop the sweat off. It took me over 30 seconds to get up off the floor, but I never gave up. I got used to working without a break. Now I'm not trying to brag, I just trying to say that if there is a goal in mind, if there is a will to succeed, then there is a way to do it. None of this stuff is a panacea, the pain is still there, but his body is relaxing, his mind becomes more meditative [since there is not much you can think about while you are exercising], and with everything a pain clinic can help with, back pain becomes much more manageable. I hope this helps in some small way.
