Neurologic Exam-Pediatric | Newborn | Normal | Tone - Popliteal Angle

Newborn - Normal 12 - Tone - Popliteal Angle: The popliteal angle is an assessment of the tone of the hamstring muscles. It is done one leg at a time. The thigh is flexed on the abdomen with one hand and then the other hand straightens the leg by pushing on the back of the ankle until there is firm resistance to the movement. The angle between the thigh and the leg is typically about 90 degrees. Extension of the leg beyond 90 to 120 degrees would be seen in hypotonia.
