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.
