Study summary

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.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. hip mobility

    measurement of hip mobility measured by goniometry

    Time frame: 5 weeks

Secondary outcomes

  1. hamstring flexibility

    hamstring flexibility measured with inclinometer, in degrees
