ClinConnect Summary

The GRIP clinical trial is studying how to measure grip strength using three different devices to find out which one works best. Grip strength is an important way to assess upper body strength in both adults and children, and the current standard device is called the JAMAR Hydraulic Hand Dynamometer. However, this trial aims to compare this standard device with two other devices—the JAMAR Smart Hand Dynamometer and the Martin Vigorimeter—to see if they are just as reliable and accurate. The researchers also want to gather reference values for grip strength based on different age groups, genders, and activity levels.

To participate in the trial, volunteers should be between 10 and 64 years old and have a healthy body weight (a BMI less than 30). If a participant is under 14, a parent or guardian must give consent. However, individuals with certain injuries, diseases affecting their arm strength, or cognitive impairments are not eligible to join. Participants in this trial can expect to engage in simple grip strength tests and help researchers gather valuable information that could improve how grip strength is measured in the future.
