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 knee-extension angle. Main Outcome Measures: Each subject's ability to actively reproduce active positioning of 3 knee angles (10, 30, and 60ø) was measured. Pearson correlation coefficients were calculated to determine correlation values for standing GR angle and absolute angular error (AAE). A 1-way repeated-measures MANOVA was computed to evaluate differences in group, angle, limb, and trial. Results: Standing GR angle correlated significantly to the AAE angle at 10ø (r=.48). The high-recurvatum group consistently scored worse, with the highest error rate occurring at 10ø. Conclusion: Individuals with GR might have diminished proprioceptive sense at end-range extension that could potentially lead to knee injury. Verf.-Referat
