Popliteal Angle and Hamstring Contracture

Posted on September 6, 2007 by David Austin

For those readers who want the latest in scientific studies, here's one that studied "the reliability of popliteal angle measurement"  This method is used to measure hamstring contracture in cerebral palsy patients

I'll let the conclusion speak for itself:

Measurements in the CP group seemed to be less reliable than measurements in the control group. Intraobserver reliability is reasonable for both groups, but lower in CP patients than in controls. Interobserver reliability of both visual estimates and goniometrical measurements is poor. No significant differences in reliability have been found between visual estimation and goniometric measurement. Because of poor interobserver reliability of popliteal angle measurement, this should not be the only variable in clinical decision making in CP patients.
