Autonomic dysfunction is common and often underrecognized in Parkinson's disease (PD). Orthostatic hypotension (OH) affects up to a third of PD patients and about half of them also exhibit supine hypertension. In current clinical practice both are undertreated. The common co-occurrence of OH and supine hypertension complicates pharmacological treatment as improvement of one can be accomplished only at the expense of the other. Head-up tilt sleeping (HUTS) is the only intervention known that could improve both. The concept of HUTS is based on several small-scale observational studies and expert opinion. Although HUTS has been proposed as an effective and even first choice non-pharmacological treatment for OH for over three decades, it is often not advised to patients because of lack of evidence on its effectiveness and on how to implement it. The Heads-Up trial is a multicenter home-based double-blind phase II RCT. The study aims to investigate the efficacy and tolerability of HUTS, leading to optimal implementation strategies of HUTS to treat orthostatic hypotension and supine hypertension.
Autonomic dysfunction is common and often underrecognized in Parkinson's disease (PD). Orthostatic hypotension (OH) affects up to a third of PD patients and often coincides with supine hypertension. This co-occurrence complicates pharmacological treatment as treatment of one can negatively affect the other. Head-up tilt sleeping (HUTS) could improve both. This phase II randomized controlled trial (RCT) aims to investigate the efficacy and tolerability of this understudied intervention, leading to optimal implementation strategies.
