The association between diagnosis of plantar fasciitis and Windlass test results.

Twenty-two patients with plantar fasciitis, 23 patients with other types of foot pain, and 30 patients in a control group were evaluated with the Windlass test performed in a weightbearing and non-weightbearing position. In the non-weightbearing test, the first MP joint was maximally dorsiflexed with the ankle stabilized. The weightbearing test was performed with the toes hanging off the edge of a stool and dorsiflexion of the first MP was performed. Seven of the 22 patients in the plantar fasciitis group had a positive weightbearing Windlass test (31.8%), while only three had a positive test result in a non-weightbearing position (13.6%). None of the patients in the other foot pain group or control group had pain in the weightbearing and non-weightbearing positions. Despite its high rate of specificity, the low rate of sensitivity of the Windlass test may limit its usefulness in the clinical evaluation in patients with plantar fasciitis.
