- Measurement of the popliteal angle is used to assess hamstring contracture in children with cerebral palsy.
- The popliteal angle in 482 normal children, 1-10 years of age, was measured.
- Using a 360 degrees goniometer, the popliteal angle was measured with the hip held at 90 degrees flexion to indicate hamstring muscle tightness.
- Between the ages of 1 and 3 years, the mean angle was 6 degrees (range, 0-15).
- A popliteal angle of greater than 50 degrees in the above age groups indicates abnormal hamstring tightness.
