About this study
The purpose of this study is to determine the effects of whole body vibration therapy on muscle firing patterns as measured by EMG analysis.
Read the detailed description
Proprioception is the specialized sensory modality that informs the body as to movement, position, and spatial orientation through mechanisms that track sensations accompanying joint movement and position. Mechanoreceptors in joints, along with vestibular, visual, muscle spindle, Golgi tendon organ, ligament and tendon sensory receptors, comprise the propriosensory system, which conveys information to the motor system to maintain equilibrium on a reflexive, automatic basis. Alterations in somatosensory input from mechanoreceptors have been identified as causing aberrant muscle firing patterns.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Whole Body Vibration in people with Healthy, run by Logan College of Chiropractic 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 6 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 2 Aug 2007. 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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Electromyographic analysis of the gastrocnemius muscle. 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 2 Aug 2007; AzTrials last refreshed its copy on 31 Oct 2026.
