Abstract

This study compared different types of grip and pinch strength measurement devices to determine their inter-instrument reliability and concurrent validity. The study included 40 females and 40 males who were tested on 2 types of grip and pinch strength measurement devices using a repeated measure design. Results indicated that the Jamar and Baseline hydraulic dynamometers have acceptable inter-instrument reliability and concurrent validity (i.e., they measure grip strength equivalently) and can be used interchangeably. Thus, therapists using the Baseline dynamometer are justified in using published normative data that were collected with the jamar dynamometer. In contrast, Baseline regular and hydraulic pinch gauges did not measure tip, hey, and palmer pinch strength equivalently with the B&L Engineering pinch gauge. As a result, therapists using Baseline pinch gauges are not justified in using published normative data that were collected with the B&L Engineering pinch gauge. Therapists should not interchange different types of grip and pinch strength measurement devices unless there is evidence that they measure equivalently.

Arm function after stroke. An evaluation of grip strength as a measure of recovery and a prognostic indicator.

D J Tinson, R L Hewer, Heath L Bradley … (1989)

The value of strength of voluntary grip as an indicator of recovery of arm function was assessed by testing 38 recent stroke patients using a sensitive electronic dynamometer, and comparing the results with those from five other arm movement and function tests (Motricity Index, Motor Club Assessment, Nine Hole Peg Test, and Frenchay Arm Test). This procedure allowed measurement of grip in a large proportion of patients, and strength correlated highly with performance on the other tests. Measuring grip over a six month follow up period was a sensitive method of charting intrinsic neurological recovery. The presence of voluntary grip at one month indicates that there will be some functional recovery at six months.

Grip and pinch strength: norms for 6- to 19-year-olds.

Jenna Wiemer, V Mathiowetz, Ross S. Federman (1986)

The purpose of this study was to establish normative data for 6- to 19-year-olds on four tests of hand strength. The Jamar dynamometer was used to measure grip strength and a pinch gauge was used to measure tip, key, and palmar pinch. A sample of 231 males and 240 females from the seven-county Milwaukee area was tested, using standardized positioning and instructions. Results of this study indicate that increases in grip and pinch strength coincide with increases in chronological age, that males are stronger than females in all age groups, and that hand dominance does not significantly affect hand strength scores. Normative data collected in this study were slightly higher than norms from previous American and Australian studies.
