Measurement of Knee-Joint-Position Sense in Women With Genu Recurvatum

Context: Proprioception of the knee joint. Objective: To determine the difference in knee-joint-angle reproduction in women with and without genu recurvatum (GR). Design: Between-subjects. Setting: Clinic. Subjects:Twenty-four women divided into 2 groups according to their standing kneeextension angle. Main Outcome Measures: Each subject's ability to actively reproduce active positioning of 3 knee angles (1 0,30, and 60") was measured. Pearson correlation coefficients were calculated to determine correlation values for standing GR angle and absolute angular error ( M E ) . A 1 -way repeated-measures MANOVA was computed to evaluate differences in group, angle, limb, and trial. Resu1ts:Standing CR angle correlated significantly to the M E angle at 1 0" (r= .48). The high-recurvaturn group consistently scored worse, with the highest error rate occurring at 10". Conclusion: Individuals with GR might have diminished proprioceptive sense at endrange extension that could potentially lead to knee injury.
