The goal of the study was to evaluate 3 common manual tests (Buell, Dananberg, and Jack tests) for assessing first metatarsophalangeal joint (MPJ) mobility and determining the normal values needed to detect FHL, and clarify the signs and symptoms associated with this pathology.Methods: Forty-four subjects were included in this reliability study. Subjects were divided into healthy control (non-FHL) and FHL groups according to the Buell first MPJ limitation values in addition to signs and symptoms derived from the literature. In both groups, we measured the mobility in the Buell, Dananberg, and Jack tests using a goniometer; their intraclass correlation coefficients (ICCs), sensitivities, and specificity indexes were also calculated.Results: All techniques showed high reliability across measurement trials with ICCs ranging from 0.928 to 0.999. The optimal mobility grades for predicting FHL were 68.6 ± 3.7 degrees, 21 ± 5.9 degrees, and 25.5 ± 6.5 degrees (mean±SD) (P < .05) for the Buell, Dananberg, and Jack tests, respectively.Conclusion: Normal and limited mobility values were established for assessing FHL using each technique. The sensitivity and specificity data were perfect for the Dananberg and Jack tests, thus identifying these tests as specific and valid tools for use in FHL diagnosis. Pinch callus was the sign most associated with FHL.
