Thanks to all who responded. I have gotten professional advice, my husband's occupation is in safety in the work place and he is trained in ergonomics. The PT is also very knowledgeable and talked with me about my limitations going forward. I had already been doing many of the things that he recommended . I will check into the standing tables that have been suggested. I mainly wanted to hear from those that were using standing lift tables as to one that will work with a machine.
