Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 2-12 years in Minnesota who can assent/consent and can follow simple instructions.

Probably not a fit

Children or adults with conditions that limit voluntary grip or who cannot complete standardized testing may not benefit from the reference values.

What this trial studies

This cross-sectional study collects normative grip strength data from a wide sample at the Minnesota State Fair using the Dinomometer. Demographic and anthropometric information will be recorded, and grip strength measurements will be taken in a standardized seated position. The goal is to establish reference values to inform clinical benchmarks for pediatric and general hand therapy practice. Participation takes about 10-15 minutes per person, with no follow-up required, and informed consent is obtained from guardians for minors. Data are collected at a designated booth and stored without personal identifiers.

Why it matters

Potential benefit: If successful, the study could provide normative grip strength reference values to guide pediatric and general hand therapy benchmarking and treatment planning.

How similar studies have gone: Previous work with similar normative grip strength data has informed clinical benchmarks, though this exact setup at a state fair is relatively novel.
