About this study

Official title: Optimising Hip Mobility, Hamstring Flexibility and Performance in Elite Sprint and Hurdles Athletes Using Lightback: an Experimental Pilot Study

In athletics, in the sprint and hurdles disciplines, muscle injuries account for a significant proportion of injuries. The hamstrings are particularly vulnerable, accounting for between 12% and 26% of all injuries in these sports. A single-blind study was conducted on 20 hurdler patients with the intention of assessing hip mobility, hamstring flexibility and performance. To collect this data, the research team will conduct examinations and interviews with the athletes in two groups: an experimental group using LightBack and a placebo group.

What participants receive

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

  • LIGHTBACKDevice

    This group will perform a standard 20-minute warm-up, and the LIGHTBACK protocol is also included.

  • PlaceboDevice

    This group will perform a standard 20-minute warm-up, but the LIGHTBACK protocol is not included and a similar placebo is used.

What is being measured

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

  1. hip mobility

    measurement of hip mobility measured by goniometry

    Measured: 5 weeks

Secondary outcomes (2)

  1. hamstring flexibility

    hamstring flexibility measured with inclinometer, in degrees

    Measured: 5 weeks

  2. performance

    It is a numerical result achieved within the jumping tests: contamovement jump (CMJ): It shall be measured using a force platform with an HD system, which ensures accurate data collection. 0 minimum, 100 maximum.

    Measured: 5 weeks

Questions about this trial

What is this clinical trial studying?

A study testing LIGHTBACK in people with Injury;Sports, run by Universidad Católica de Ávila at 1 site in Spain.

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 9 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: looking for participants now, as of the sponsor's last update on 6 Feb 2025. 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 Spain. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact JORGE Velázquez Saornil, PhD. (655909940, jvelazquezsa@upsa.es), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

hip mobility (time frame: 5 weeks). 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 NCT06811883, which also lists 6 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 6 Feb 2025; AzTrials last refreshed its copy on 28 Oct 2026.
