Grip strength testing using the BTE work simulator and the jamar dynamometer: A comparative study

This study compared the results obtained from testing grip strength using the hydraulic Jamar dynamometer and the BTE Work Simulator. The grip strength of 14 adults was assessed with the Jamar at 90^o elbow flexion, Jamar at 45^o elbow flexion, and the BTE using the manufacturers recommended position. Greater strength measurements were generated with the elbow at 90^o rather than 45^o on the Jamar. The Jamar measurements at 90^o of elbow flexion were not significantly different from the BTE work simulator values. Intraclass correlation coefficients between the Jamar at 90^o and the BTE work simulator values were excellent. This study demonstrated that the results obtained from the BTE work simulator and the Jamar dynamometer are comparable. These findings validate the use of the BTE work simulator for grip strength testing.
