Résumé :	OBJECTIVE. This study sought to determine interinstrument reliability of the Jamar electronic dynamometer and pinch gauge compared with the commonly used Jamar hydraulic dynamometer and B&L Engineering mechanical pinch gauge. METHOD. Twenty men and 20 women were tested for grip strength with the two different dynamometers, and 17 men and 25 women were tested for lateral pinch strength with the two different pinch gauges. RESULTS. Grip strength measurements were approximately 10% higher with the hydraulic dynamometer, and lateral pinch strength measurements were approximately 18% higher with the mechanical pinch gauge. Paired t tests and intraclass correlation coefficients (ICCs) were used for statistical analyses. The two-tailed p value was <.0001, and the ICC indicated poor to moderate reliability. CONCLUSION. When retesting patients, it is recommended that occupational therapists use the same instrument to measure hand strength because interinstrument reliability may be lacking.
