Abstract

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° goniometer, the popliteal angle was measured with the hip held at 90° flexion to indicate hamstring muscle tightness. Between the ages of 1 and 3 years, the mean angle was 6° (range, 0-15). At age 4, the angle rose to 17° in girls and 27° in boys (range, 5-45). At s=5 years the mean angle was 26° with little change (range, 0-50). A popliteal angle of >50° in the above age groups indicates abnormal hamstring tightness.
