Which type of rehabilitation programs or resources would elders use?

Aquatic exercise: Check the local community or senior center. Swim , water aerobics or walking in chest deep water. We are about 80% lighter standing in chest deep water due to buoyancy. This will make exercising easier. Start with an amount that is relatively easy and comfortable, then repeat 3 or more days per week then add a few minutes to the program once a week. Don't over do it. Slow but steady wins the race.
