Are portable folding chairs useful to combat orthostatic hypotension?
The effect of sitting on a derby chair (height, 48 cm), fishing chair (38 cm), and footstool (20 cm) on the improvement of postural hypotension was studied serially in 8 patients with autonomic failure. The increment in blood pressure during sitting was higher by using a lower portable chair. This was related to an increasing cardiac output at lower sitting heights. The fishing chair was, according to our patients' experience, most useful.
