About this study

Official title: Expectation and Response to Levodopa & Acupuncture in Parkinson's Disease

To investigate how levodopa and acupuncture affect fatigue and muscle function in people who suffer from Parkinson's disease. Subjects may choose to participate in levodopa or acupuncture part, or both. Study procedures include an exercise protocol, transcranial magnetic stimulation (a non-invasive type of brain stimulation that cause small muscle twitch), a blood draw, and personality surveys.

Read the detailed description

Subjects will answer surveys, have their blood drawn, undergo TMS and perform an exercise. The TMS/exercise task will measure fatigue and muscle response. The surveys will describe personality and measure fatigue. The CTRC will do genotype studies on the blood to look for genetic differences. Each subject is eligible to receive both study treatment types (levodopa and acupuncture). Depending upon the study treatment type they choose, each subject will be randomly assigned to one of six possible subject groups:

Ia. Full expectancy; levodopa: Subjects will be told that they are taking levodopa.

Ib. Half expectancy; levodopa: Subjects will be told that they have 50% chance of receiving levodopa or placebo.

Ic. No expectancy; levodopa: Subjects will be told that they are receiving placebo levodopa.

IIa. Full expectancy; acupuncture: Subjects will be told that they are receiving real acupuncture.

IIb. Half expectancy; acupuncture: Subjects will be told that they have 50% chance of receiving real or sham-acupuncture.

IIc. No expectancy; acupuncture: Subjects will be told that they are receiving sham-acupuncture.

Subjects will attend four visits for the levodopa part and/or three visits in the acupuncture part. On the first visit, subjects will answer questionnaires and have samples of their blood collected. On the other visits, subjects will undergo TMS while they perform a repetitive exercise task. Subjects will then either wait for 30 minutes or receive the investigative intervention that they have been randomly assigned for that particular visit, and then repeat the TMS/exercise task.

Questions about this trial

What is this clinical trial studying?

A study testing Levodopa or acupuncture in people with 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 3 inclusion and 5 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 5 May 2015. 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. Some participants in this study may receive a placebo. 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?

Fatigue rate and muscle response evoked by transcranial muscle stimulation (TMS) (time frame: Before and immediately after the intervention). 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 5 May 2015.
