Abstract

This retrospective study investigated the validity of hand-grip dynamometry with respect to its use in predicting generalized upper extremity strength. The records of 37 patients (mean average age, 77.7 years) receiving home care were used. Discriminant construct validity was examined by comparing their dynamometry measurements with measurements of age- and gender-matched healthy individuals reported in the literature. Convergent construct validity was described by the correlations of their dynamometry measurements and manual muscle test scores of the upper extremities. The patients' dynamometer-measured grip forces were significantly less than reported normative values. The patients' dynamometer measured grip forces were correlated significantly with their manual muscle test scores. These findings support the construct validity of hand-grip dynamometry for characterizing upper extremity strength impairment among adults treated in a home care setting.

    When we compare these results with the TW and PT correlations of Nascimento et al. (2012) study, there were similar results in the study, but the authors did not point it out. Therefore, as HG dynamometers are relatively one of the inexpensive, simple, and clinically useful methods to measure the total upper limb strength than isokinetic dynamometers (Adams et al., 2004; Bohannon, 1998; Mandalidis and O'Brien, 2010), and the findings of this study suggested that measures of HG strength could be used to estimate and monitor the muscular performance of the ER muscles of shoulder among the population of elite SV players. It's important to point out that, HG dynamometer’ estimate is closer to the TW values than the PT values of the isokinetic dynamometer.
