About this study
The researcher can use Diffuse Optical spectroscopy technique that uses harmless levels of near-infrared light to probe the concentrations and states of important physiological molecules such as hemoglobin water and lipids in human muscle,.
Read the detailed description
The researcher can monitor muscle physiology, for example during exercise or in response to external factors such as shock by Diffuse Optical spectroscopy technique.
The Diffuse Optical spectroscopy technique can determine significant changes in muscle, muscle structure, muscle tissues metabolism and hemodynamics.

Questions about this trial
What is this clinical trial studying?
An observational study of Muscle Disorder, run by University of California, Irvine 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 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The record says: withdrawn, as of the sponsor's last update on 20 Oct 2022. 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The study was withdrawn before enrolling participants, so there are no results.
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?
Healthy Muscle (time frame: upto 4 weeks). 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 20 Oct 2022.
