Currently, there are no universally accepted assessment methods for detecting insincere
effort during grip strength testing. We examined the validity of the slopes of the force-time …

This was a prospective cohort study. In a previous study, the slopes of the force–time (F–T)
curve were shown to differentiate between maximal and submaximal grip effort in healthy …

We devised a sincerity of effort assessment based on “tricking” a person into exerting
maximal effort by providing incorrect visual feedback. The assessment involves deriving a …

Abstract Gutierrez Z, Shechtman O: Effectiveness of the five–handle position grip strength
test in detecting sincerity of effort in men and women. Am J Phys Med Rehabil 2003; 82: 847 …

Controversy exists in the literature concerning the ability of the five-rung grip test to identify
submaximal effort. The purpose of this study was to analyze four methods commonly used to …

The purpose of this study was to investigate the testretest reliability of isometric grip strength
testing using the Jamar dynamometer. Thirty-three subjects, 16 men (mean age= 37.4 years) …

The coefficient of variation (CV) is commonly used to detect sincerity of effort. The purpose of
this study was to examine whether the CV possessed adequate sensitivity and specificity to …

STUDY DESIGN: Retrospective Cohort. INTRODUCTION: Detecting sincerity of effort (SOE)
of grip strength remains a frustrating and elusive task for hand therapists because there are …

The wide use of the coefficient of variation in detecting sincerity of effort is puzzling since
existing research findings regarding its effectiveness are contradictory. The lack of empirical …

Many clinicians use the coefficient of variation (CV) to assess sincerity of effort, without
understanding the premise on which it is based or its physiological and mathematical bases …
