Trial summary

The purpose of this study is to learn more about balance and strength in an elderly population (60 and older). Data will be compared between controls and the age/gender- matched PD participants in study "The Effects of vitamin D on Balance in Parkinson's disease" (OHSU IRB # 6482). Read more about this study

About this study

Official title: Strength and Balance in Gender- and Age-Matched Controls: SubStudy to "The Effects of Vitamin D on Balance in Parkinson's Disease"

The purpose of this study is to learn more about balance and strength in an elderly population (60 and older). Data will be compared between controls and the age/gender- matched PD participants in study "The Effects of vitamin D on Balance in Parkinson's disease" (OHSU IRB # 6482). Specifically a t-test will be used to compare total work and total power on leg extension and flexion, composite SOT score conditions 1-3 and 4-6, response strength and latency on MCT, and turn duration from the iMOBILITY between the two groups.

Read the detailed description

Inclusion Criteria:

  • Over the age of 59
  • Gender and Age-Matched (within 3 years) of main protocol participants

Exclusion Criteria:

  • Parkinson's disease diagnosis
  • Significant cognitive deficits.
  • Another neurological or orthopedic deficit that in the investigator's opinion would have a significant impact on gait and cognition (e.g. stroke, fracture).

This study involves one visit to Oregon Health \& Science University. The study visit will last approximately 2 hours.

Measurements:

  1. The participant's balance will be assessed by having them stand on a platform and completing mental tasks such as naming the alphabet backwards. They will be asked to have their eyes open on some tasks and closed on other tasks. For safety, they will wear a harness like those used by rock climbers.
  2. The participant's ability to move and balance will be measured by putting six sensors on their bodies (both wrists, both ankles, chest, and back). Each sensor is about the size and weight of a deck of cards. To measure movement and balance, participants will rise from a chair, walk three feet, turn around, walk back to the chair, and sit down.
  3. The participant's strength will be evaluated using a machine that resembles a stationary exercise bike. They will have one leg and foot strapped onto the machine. Participants will then be asked to flex and extend their leg as quickly as possible five times. This will be repeated with the other leg.

What is being measured

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

  1. Strength (BIODEX)

    The participant's strength will be evaluated using a machine that resembles a stationary exercise bike. They will have one leg and foot strapped onto the machine. Participants will then be asked to flex and extend their leg as quickly as possible five times. This will be repeated with the other leg.

    Measured: Visit 1

Secondary outcomes (1)
  1. Balance (SOT)

    The participant's balance will be assessed by having them stand on a platform and completing mental tasks such as naming the alphabet backwards. They will be asked to have their eyes open on some tasks and closed on other tasks. For safety, they will wear a harness like those used by rock climbers.

    Measured: Visit 1

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy Volunteers, 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 2 inclusion and 3 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 20 Oct 2014. 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?

Strength (BIODEX) (time frame: Visit 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02110875, which also lists 5 linked publications.

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 20 Oct 2014.
