About this study

Official title: Postural Instability in Progressive Supranuclear Palsy: Why do Patients With PSP Fall?

The purpose of this study is to better understand why individuals with Progressive Supranuclear Palsy (PSP) fall. Understanding the mechanism of gait and balance dysfunction in individuals with PSP may provide us with important early diagnostic tools, allowing for earlier identification of mobility problems and to better evaluate medical therapies aimed at improving motor disability.

The investigators will recruit 10 PSP, 10 PD and 10 healthy controls for the study. All subjects will be asked to come to the OHSU clinic at the Center for Health and Healing for an initial screening visit. They will meet with the primary investigator to conduct a brief interview and physical examination. In addition, they will be asked to answer questions regarding current and past medical illness, how often they fall and what kinds of medications they are on.

Subjects who agree to participate will come to the Oregon Clinical and Translational Research Institute (OCTRI) at OHSU for balance testing. Subjects will be asked to stand or sit on a movable platform with eyes open or closed. Prior to standing on the platform, the investigators will place 6 small sensors on body which are held in place by velcro straps (one on each wrist, ankles, chest and lower back). The platform will then be moved (tilt or slide) while subjects try to keep their balance. During all of the balance tests described above, body movements will be recorded from the sensors on the subjects' body. This data is directly recorded by a computer and analyzed to help us gain better understanding of the subjects' posture and their ability to remain up right.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relative contributions of vestibular and visual information to postural control in PSP

    To gage the relative contributions of vestibular and visual information to postural control in PSP we will measure body sway using two different tests (LOS and SOT) while a patient stands on a movable force plate within a movable visual surround.

    Measured: Single visit. 2 hours.

Secondary outcomes (3)
  1. Postural Response Latencies

    Subjects will stand on a movable platform with a movable visual surround. Subjects will be asked to keep their balance while the platform is translated or roated.

    Measured: Single visit. 2 hours.

  2. Gait patterns and postural transitions

    Subjects will be asked to rise from a chair, walk and turn. Ambulatory balance will be measured by a time up and go test (TUG). Six accelerometers will be placed on the subject and will measure parameters including arm swing, number of steps and turn duration.

    Measured: Single visit. 10 minutes.

  3. Perception of vertical and horizontal references

    Subjects will perform two different tasks with their eyes closed while standing and sitting on a force plate that is tilting in the antero-posterior direction. They will perform the following two tasks: 1. Hold a rod parallel to the gravitional vertical 2. Hold a rod perpendicular to the tilting surface so it remains 90 degrees to the surface at all times. Six accelerometers will measure lower and upper body tilt.

    Measured: Single visit. 2 hours.

Questions about this trial

What is this clinical trial studying?

An observational study of Progressive Supranuclear Palsy and Parkinson's Disease, run by Oregon Health and Science University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Relative contributions of vestibular and visual information to postural control in PSP (time frame: Single visit. 2 hours.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Sep 2019.
