Title: The Wall Slide Test, a measure of knee extensor strength
Authors: Loucks, Lynda Loreen
Issue Date: 1-Jul-2001
Abstract: 'Purpose'. To develop and evaluate a clinical test for assessment of knee extensor strength using a mathematical algorithm (Wall Slide Algorithm - WSA) to compute the knee extensor resultant joint moment (RJMk). 'Methods'. Normal subjects (n = 25) executed a knee flexion and extension maneuver with the trunk constrained against the wall and with feet a standardized distance from the wall (The Wall Slide Test - WST). The WST was repeated on two separate occasions (3-7 days between tests) for assessment of reliability. The absolute thigh angle for the lowest point during the WST was measured using a digital inclinometer. Digital images were taken of a sub-sample of subjects (n = 11/25) for comparison of the WSA with a full static analysis. For evaluation of concurrent validity, the subjects performed a maximal, concentric strength test on an isovelocity dynamometer at 50/s on their dominant leg on the second test day. The angle value measured during the WST was entered into the algorithm, ' 8.31Massbltcos [theta]', which calculated the RJMk. (Abstract shortened by UMI.)
