My dad has balance,gait walking probs, uncontrolled movement in feet

Hello, 1 year ago, my dad had double knee replacement sutgery.. complications of anemia(they gave him 4 blood transfusions) and was on procrit for a long time. Besides that.. his Kidney is not functioning well... but controls it with diet...at this point.
My father is having horrible problems with his balance and gait..although the surgeon says its not from knee op... the other horrible prob..is that my dad has uncontrolled movement in his feet and legs..that cause his feet to flex..and his toes,especially the big toes arch back toward the top of the foot...in a locked postion..I try to massage the toes..and I cannot...as they are stiff..horribly stiff arching backwards.. this was going on... before my dad had his knee op..ohly its gotten much worse since then.. he's had many MRIs showing neck soine fusions.. the other day he went to see a nuerosurgeon..he told my dad to close his eyes... then he did certain things with my dads feet and aske him...are your feet flexed or pointed..my dad could not tell.... the doctor said he doesn't know what is wrong and told him to seek out another neurologist... have you heard of anything like this. My dad is 77 years old and although diabetes is heavy in his family... he has a high sugar count but doc says not diabetes.. thank you for any help you can give me! Meredith Biegel

What you are describing may be spasms in his legs, and signs of a problem either in his thoracic or cervical spine, or possible his brain. I would agree with the other doctor that your father needs to see a neurologist. Based on the doctors examination  and history it may be possible to determine if this is a spine or brain problem. A MRI of the brain cervical and thoracic spine may need to be performed/reviewed. Besides a structural lesion which would be seen on a MRI, other things which could be considered include B12 deficiency, inflammatory disorders, or vascular abnormalities either within the spine or brain. Without more information, I can not be more specific. Good luck.
