Reliability of the Passive Properties of the Calf Muscles in Healthy Subjects Assessed Using Isokinetic Device

France16 participantsStarted 2018-06-12

Plain-language summary

The investigators designed this study to determine the test-retest reliability of the viscoelastic passive properties of the calf muscles assessed using isokinetic device in flexed and extended knee position. The second objective is to determine the clinical viability of the parameters using the coefficient of repeatability and to investigate the individual characteristics associated with increased calf stiffness or altered viscoelasticity

Inclusion Criteria: * Patient who signed the research information form * Patient affiliated to a social security system * An active patient, under 45 years of age, who participates in at least 4 hours of physical activity per week Exclusion Criteria: * Individuals unable to perform an isokinetic muscle testing * Individuals with a current or recent lower limb injury with time loss from sport participation within the previous month.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Change from Baseline stiffness parameters at 15 days to assess the reproducibility of stiffness parameters

Timeframe: Two evaluations on both dominant and non dominant knees: one evaluation at the first visit, and a second evaluation at the second visit at 15 days after the first visit

Change from Baseline viscoelastic parameters at 15 days to assess the reproducibility of viscoelastic parameters

Timeframe: Two evaluations on both dominant and non dominant knees: one evaluation at the first visit, and a second evaluation at the second visit at 15 days after the first visit
