Reference Values and Reliability of Handgrip Strength Assessment Using a Digital Dynamometer in Healthy Adolescents and Other Populations: A Pilot Observational Study
Spain50 participantsStarted 2025-11-06
Plain-language summary
his study aims to establish reference values and examine the reliability of handgrip strength assessment using a digital dynamometer (VALD DynaMo) in healthy adolescents.
Participants will undergo standardized strength evaluations of upper and lower limbs, following international testing guidelines.
Descriptive variables such as age, sex, height, weight, hand dominance, and physical activity level will also be recorded.
The results will contribute to developing normative data and validating the use of portable dynamometry for musculoskeletal health assessment, with potential future applications in clinical populations.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Healthy adolescents aged 15-16 years (for the current phase).
* Ability to understand and follow verbal instructions.
* Written informed consent provided by parent or legal guardian (for minors).
* Assent given by the adolescent participant.
* In future extensions: individuals aged 10-80 years, including those diagnosed with musculoskeletal, neurological, or oncological conditions, able to safely perform isometric contractions.
Exclusion Criteria:
* History of acute or chronic upper or lower limb injury in the last 6 months.
* Neurological, cardiovascular, or systemic disorders that may limit maximal effort.
* Current pain, inflammation, or post-surgical condition affecting muscle performance.
* Cognitive or communication impairments preventing valid testing.
* Refusal or withdrawal of informed consent at any point.
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?

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.
