This is a monocentric, randomized, placebo-controlled, double-blind, crossover phase II clinical trial with an open-label treatment extension phase. The investigators plan to recruit n = 30 individuals with MSA-P or PD with known or suspected OH.
At the Screening Visit, after patient information and written informed consent, the participants will first undergo a comprehensive neurological and cardiological evaluation, as well cardiovascular autonomic function testing to confirm the diagnosis of symptomatic, neurogenic OH.
Afterwards, the participants will be asked to wear physical activity monitoring (PAM) sensors for five consecutive days and to measure the blood pressure (BP) regularly following a home BP diary (i.e. Home Phase I).
On treatment day-1 (i.e. Visit 1), the participants will undergo an instrumented in-lab gait analysis, followed by a head-up tilt and active standing test. Afterwards, they will wear the first type of binder for two hours (either the investigational elastic abdominal binder or the placebo-comparator binder, depending on the randomization assignment). At the end of the two hours, the participants will repeat the in-lab gait analysis and the head-up tilt-/active standing test.
After one-day wash-out, the same procedure of treatment day-1 (i.e. Visit 1) will be repeated with the outstanding type of binder (i.e. treatment day-2, Visit 2).
At the end of this, all participants will be invited to wear the investigational elastic abdominal binder and the PAM sensors for five more days and to repeat the home BP measurements (i.e. Home Phase II).
A final follow-up visit is scheduled to return the PAM sensors, the BP monitor and to detect eventual adverse and serious adverse events occurred during Home Phase II.

Arm | Intervention/treatment |
---|---|
Placebo Comparator: Placebo binder first
Participants in this arm will wear the placebo comparator ("Clima Care" body warmer, Bort Medical GmbH) for 2 hours on treatment day-1 (i.e. Visit 1), followed by the active comparator ("ABDO-SYNCRO 3-BAHNIG" elastic abdominal binder, SYNCRO-MED GmbH) for 2 hours on treatment day-2 (i.e. Visit 2).

Device: Elastic abdominal binder
The "ABDO-SYNCRO 3-BAHNIG" is an elastic abdominal binder with a 3-stripes Velcro fastening, capable of developing a 20 ± 2 mmHg pressure on the abdominal wall. This device will be tested as potentially beneficial with respect to the mentioned primary and secondary outcomes. The investigators anticipate to use this elastic abdominal binder, since participants of a previous trial reported this device to be comfortable enough and to have used it regularly during the open-label follow-up phase. Size will be chosen depending on the abdominal circumference of the participant, according to the size tables provided from the manufacturer (SYNCRO-MED GmbH).
Other Name: "ABDO-SYNCRO 3-BAHNIG" elastic abdominal binder, SYNCRO-MED GmbH Device: Placebo binder "Clima Care" is a simple body warmer, developing maximal 3±2 mmHg pressure on the abdominal wall. This device will be used as placebo comparator of the present clinical trial. Size will be chosen depending on the abdominal circumference of the participant, according to the size tables provided from the manufacturer.

Participants in this arm will wear the active comparator ("ABDO-SYNCRO 3-BAHNIG" elastic abdominal binder, SYNCRO-MED GmbH) for 2 hours on treatment day-1 (i.e. Visit 1), followed by the placebo comparator ("Clima Care" body warmer, Bort Medical GmbH) for 2 hours on treatment day-2 (i.e. Visit 2).
