Brief Summary

The purpose of this study is to evaluate the performance of the Dinomometer and establish normative data to inform clinical standards and benchmarks for therapeutic practice. This is a cross-sectional study designed to collect normative grip strength data from a large sample of the general population in Minnesota. Participants will primarily be recruited from attendees of the Minnesota State Fair. Grip strength will be measured using the Dinomometer, a non-invasive handheld grip strength measurement device. The study should take approximately 10-15 minutes to complete for each participant including enrollment and completion of study procedures. Follow-up is not required.

Outcome Measures

Primary Outcomes (1)

• Collection of normative grip strength data using the Dinomometer

  The primary outcome is the collection of normative grip strength data from a large sample of the general population in Minnesota using the Dinomometer. These data will be used to establish reference values and benchmarks to inform clinical interpretation of Dinomometer measurements in therapeutic settings.

  During a single study visit lasting approximately 10-15 minutes

Secondary Outcomes (1)

• Grip strength variability across demographic subgroups

  During a single study visit lasting approximately 10-15 minutes

Study Arms (1)

Dinomometer Grip Strength Assessment

EXPERIMENTAL

Participants will complete grip strength measurements using the Dinomometer, a non-invasive handheld grip strength measurement device. Grip strength will be measured on each hand, with short rest breaks and alternation between hands to mitigate the effects of fatigue.

Device: Dinomometer

Interventions

Dinomometer DEVICE

The investigational device being evaluated in this study is the Dinomometer, a handheld grip strength measurement device designed for use in pediatric populations. The Dinomometer will be used to collect grip strength measurements from participants at the Minnesota State Fair. No drugs, biologics, or additional investigational agents are involved in this study.

Also known as: Handheld grip strength measurement device
