Low-Cost Handgrip Dynamometer in Healthy Adults

Active, not recruiting

• Conditions: Healthy; Hand Grip Strength

• Registration Number: NCT06845072
• Lead Sponsor: University of Yalova

Brief Summary

The gold standard device for measuring grip strength is the Jamar® Hydraulic Hand Dynamometer. The Jamar® Hydraulic Hand Dynamometer is a high-priced device. It has an analog reading feature. The Jamar hydraulic hand dynamometer is recommended by the American Association of Hand Therapists and is considered the gold standard because of its high validity and reliability. Due to its cost, the use of this dynamometer is quite limited in certain countries and settings. However, there is a new version, the JAMAR Plus+, which has a digital reading feature. This version is even more expensive. In recent years, the use of less expensive dynamometers for measuring grip strength has become increasingly common in clinical settings and scientific research. In particular, the Camry Dynamometer, which is ten times cheaper, is frequently used. Despite its frequent use in scientific research, a review of the current literature has shown that the validity and reliability of the Camry has not been examined in healthy populations. Our study compares the Jamar® Hydraulic Hand Dynamometer, the gold standard device for measuring grip strength, with the lower cost and lighter handheld digital Camry dynamometer.

Primary Outcome Measures

Name	Time	Method
Maximum handgrip strength - Device 1	7 days	Maximum grip strength is a measure of muscular strength or the maximum force/tension generated by one's forearm muscles.
Maximum handgrip strength - Device 2	7 days	Maximum grip strength is a measure of muscular strength or the maximum force/tension generated by one's forearm muscles.

Secondary Outcome Measures

Name	Time	Method
International Physical Activity Questionnaire - Short Form	Baseline	The purpose of the questionnaire is to provide common instruments that can be used to obtain internationally comparable data on health-related physical activity. The total score is grouped as inactive (\<600 MET-min/week), minimally active (minimum 600 MET-min/week and \<3000 MET-min/week) and active (\>3000 MET-min/week).
SBQ - Sedentary Behaviour Questionnaire	Baseline	The SBQ was designed to assess the amount of time spent doing 9 behaviors (watching television, playing computer/video games, sitting while listening to music, sitting and talking on the phone, doing paperwork or office work, sitting and reading, playing a musical instrument, doing arts and crafts, sitting and driving/riding in a car, bus, or train). The 9 items were completed separately for weekdays and weekend days.
