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 60°) was measured. Pearson correlation coefficients were calculated to determine correlation values for standing GR angle and absolute angular error (AAE). A1 -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 10° (r = .48). The high-recurvatum group consistently scored worse, with the highest error rate occurring at 10°.
Conclusion:
Individuals with GR might have diminished proprioceptive sense at end-range extension that could potentially lead to knee injury.
