Review of sincerity of effort testing

Occupational rehabilitation professionals have for many years recognised the need to develop methods to determine whether a genuinely maximal effort is being given during clinical strength testing. A number of different sincerity of effort tests have been devised in an attempt to satisfy this need, however, in most cases the accuracy and reliability of these tests have not been adequately researched. This article reviews three of the most commonly-used sincerity of effort tests.
