Key result
Bedridden patients with severe multiple disabilities exhibited autonomic inactivity in cardiovascular regulation during orthostatic and lower body negative pressure tests, characterized by parasympathetic deterioration compared to healthy controls.
Why the study?
How do anti-gravity posture and lower body negative pressure affect heart rate variability in bedridden persons with severe multiple disabilities compared to healthy subjects?
Observational (n=39)
How do anti-gravity posture and lower body negative pressure affect heart rate variability in bedridden persons with severe multiple disabilities compared to healthy subjects?
Even passive sitting in daily life may help preserve some autonomic cardiovascular regulation in persons with severe multiple disabilities compared to being completely bedridden.
Hypothesis-generating for passive sitting to preserve autonomic function in severe disabilities; prospective trials needed before practice change.

Mita et al. (1996) conducted an observational in Severe multiple disabilities (n=39). Orthostatic sitting test and lower body negative pressure test vs. Healthy normal persons was evaluated on Heart rate variability (HRV) power spectral density. Bedridden patients with severe multiple disabilities exhibited autonomic inactivity in cardiovascular regulation during orthostatic and lower body negative pressure tests, characterized by parasympathetic deterioration compared to healthy controls.
