The following are tests conducted by NASA before, during and after bedrest.  Any yellow LINK signifies a test for which I provided a description and photos.

Also bear in mind that I am not a medical doctor, and am not aiming for textbook accuracy beyond layman's terms; I describe my subjective opinion of each experience, but speak only for myself and no other test participants :)
