well, not being a neurologist, but on the basis of what I read about diagnostic reflexes, I can say that pyramidal damage does not correlated with flat (diminished) limb deep tendon reflexes you report in your previous posts.Extrapyramidal or pyramidal damage is a damage of central motor neurons and should mean spactic paralytic issues and hypertonus and hyperreflexia, not weak pralysis and loss of reflexes your report. Typical extrapyramidal sings are convulsive movements (athetoses), pendulum-like involuntarily hand movemets, catatonias (involuntary frozen posture) etc. Examples of extrapyramidal symptomes may be typical clinical pictures of Hantington disease (chorea, st. Witt dance), Parkinson disease (tremors, rigidity), catatonic issues happen to people with schisophernia (due to imbalance of dophamine in the brain) and side effects from neuroleptic drugs.also other cases (other than central and spinal brain damage) resulting in visual abscence of abdominal skin reflexes are- too nervous and strained patient (I can imagine you are quite nervous due to pain and all that situation)- patient with a belly, non-trained muscles of abdomen (ladies of our age are ususally of that type), patinet with extra fat on the belly- patient with abdominal operations history (in our case most probably is Cesarian operation)I also remember you complained for feeling of pressure in the chest like it was too tense around. If your diminished abdominal skin reflexes are not an error due to aforesaid reasons (overall nervous tension, belly conditions, Cesarian or other abdominal surgery etc.), then one may fit another pointing towards local spinal damage at toracic level (it correlates also with the weakness etc. concentrated in your hands, not legs).That is just to give you another picture compared to extrapyramidal damage.
