pure autonomic failure induces OI because compensatory factors governed by the autonomic nervous system are inadequate&#46; Patients with this condition not only cannot easily stand but clearly have detectable autonomic abnormalities in all positions&#46;

pure autonomic failure induces OI because compensatory factors governed by the autonomic nervous system are inadequate&#46; Patients with this condition not only cannot easily stand but clearly have detectable autonomic abnormalities in all positions&#46;
