Randomized Controlled Trial Clinical TrialDetection of feigned tactile sensory loss using a forced-choice test of tactile discrimination and other measures of tactile sensation.
Intentional exaggeration of disability is a risk in work injuries but is hard to reliably detect clinically. This study examined the accuracy of tactile sensory threshold and forced-choice discrimination measures in detecting feigned sensory loss. ⋯ Below-chance scores are definitive evidence that the sensory loss is intentionally feigned. Scores beyond cut-offs should raise the clinician's suspicion of malingering if there is no physical basis for sensory loss.
