About this study

Official title: Improving Low Bone Mass With Vibration Therapy for Girls With Adolescent Idiopathic Scoliosis (AIS) - A Randomized Controlled Trial

This is a prospective randomized controlled trial investigating the effect of vibration therapy on bone mineral density (BMD) and bone quality in AIS subjects suffering from osteopenia (low bone mass).

Read the detailed description

Scoliosis is a three-dimensional spinal deformity and AIS is the commonest with a high prevalence of 2-4 % in the general population. As many as 30% of AIS subjects also suffer from osteopenia which can persist and result in serious health problems later in life including vertebral collapse, fragility fractures, decreased quality of life and even mortality. In spite of this, a safe, effective and evidence-based treatment protocol for AIS-related osteopenia is not available. It remains uncertain how effective dietary advices, physical activity, Calcium and Vitamin D supplements are in this regard. On the other hand, low-magnitude high-frequency vibration therapy was shown to be effective in increasing bone mass both in animal models and in clinical trials involving elderly subjects. AIS-related osteopenia may have a different clinical behaviour. In addition, the in-vivo effect on bone quality has never been studied. We plan to carry out a scientific clinical study on the effect of vibration therapy on skeletally mature female AIS subjects with osteopenia. They are randomly allocated to either the treatment or the control group. BMD, bone micro-architectures are assessed to delineate whether vibration therapy has any therapeutic effect on improving low bone mass in osteopenic AIS subjects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Vibration PlatformDevice

    The patients receive treatment by standing on the Vibration Platform 20 minutes a day, five days a week. The platform will deliver a vibration of 0.3g with a vertical displacement of 0.085mm at 35 Hz.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Vibration Platform in people with Scoliosis and Bone Diseases, Metabolic, run by Chinese University of Hong Kong at 1 site in China.

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 7 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 29 Jul 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 China. 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Bone mineral density (time frame: 1 year). 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 29 Jul 2015.
