Lower Extremity Tone on Physical Exam Assessing motor function of the lower extremities begins with passive range of motion. This is done by flexing the hips, then abducting and adducting the hips. Next, flex and extend the hips, the knees and ankles. Further testing helps to better define the tone and any tone abnormalities. #LowerExtremity #tone #Newborn #PhysicalExam #clinical #video #peds #pediatrics
