If you are still using standard testing methodology and analysis to assess validity of effort during a hand strength assessment, consider the following quotes.  Deborah Lechner, PT and President of ErgoScience weighs in on the subject of outdated testing methods, as you can seen in the box below as well as in the link below the box.

                                                                                                                                   "Clinicians are advised to avoid using the coefficient of variation, rapid exchange grip and bell-shaped curve . . . . for detecting sincerity of effort." (Lechner et al., Physical Therapy, 1998).  Click on this sentence for more.

"No single grip strength test has yet been described which unequivocally detects malingerers." (Tredgett et al., British Journal of Hand Surgery, 1999)

"The CV is not an appropriate method for determining whether an effort is sincere." (Shechtman, American Journal of Hand Therapy, 2000)

"One of the most important things is sincerity.  If you can fake that, you can do just about anything." (Kinky Friedman, Greenwich Killing Time, 1986)
