The detection of feigned hand weakness using the five position grip strength test.
This study assessed the sensitivity and specificity of the five-position grip strength test (5PGST) for detecting feigned hand weakness in healthy volunteers. The 5PGST reliably detected feigned hand weakness in only 15% of cases. Thirty-three per cent of volunteers demonstrated an entirely normal pattern of grip strength when feigning weakness.
