What Causes Weakness In Legs Upon Sitting For A While?

My husband s legs are weak after sitting awhile or if he walks a distance. On several occasions they have given out on him and he fell. He is 78, overweight with AFib. His legs were tested for circulation problems but nothing amiss was found. He is under doctors care for other other issues, but nothing definite has been found for the leg problems.
