Effects of Genu Recurvatum on Postural Control: A Preliminary Study

摘要

Genu recurvatum has been associated with proprioception deficits and a predisposition to knee ligament injury. The primary purpose of this study was to investigate the effects of genu recurvatum on two common tests of postural control. Eleven subjects with bilateral genu recurvatum were matched with 11 controls. Force plate data were acquired while subjects were tested for steadiness during one leg standing balance and the balance leg reach test. Results failed to demonstrate a significant difference between groups except for the measure of maximum anterior-posterior sway during the functional balance leg reach test. All force plate variables indicated significant postural unsteadiness in the balance leg reach test compared to the one leg stance test. Clinicians might consider combining force plate data with functional testing to enhance the predictive value of these tests.
