How does the DynEx dynamometer compare to the JAMAR dynamometer?.
Answ: A study of the DynEx was conducted by the University of Florida in 2004. The purpose of this study was to examine the reliability and validity of the digital DynEx dynamometer. When compared to the JAMAR, the DynEx dynamometer was found to have a smaller measurement errormore than 4 times better in fact. The concurrent validity between JAMAR and DynEx was excellent and within 98% of each other. The results of this study indicate that clinicians can use the DynEx dynamometer at commonly used 2nd JAMAR handle position knowing that it is reliable, valid and comparable to the JAMAR. Ques: When a series of grip strength measurements are made with DynEx, are the data stored for recall? Answ: Yes. All data collected is stored until it is overwritten by a next set of measurements. The DynEx can be turned off and these data are retained for review prior to next use. Ques: Does the DynEx need re-calibrated periodically? Answ: No, the electronic load cells avoid the problem of air seepage i
