Abstract

Fillyaw et al, in this article, and Nelson and Duncan in a recent article,1 should be commended for enlightening the clinician-researcher on this basic measurement error in isokinetic dynamometer testing in antigravity positions. In determining the strength of hamstring and quadriceps femoris muscle groups, the authors selected the most common isokinetic assessment area of the body. Fillyaw et al have identified the effects of gravity in the recorded torque values at slow (60°/sec) and fast (240°/sec) velocities for the two muscle groups. This gravitational influence was termed gravity effect torque (GET), which was calculated by considering the combined weight of the dynamometer arm and the leg and foot. The protocol Fillyaw et al used for determining the gravity correction factor was based on the method proposed by Nelson and Duncan.1
