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.
