The therapist keeps the patient’s left foot on his thighs, grabs his ankle with the right hand and plantar flexes (towards the sole) the patient’s toes with the left hand in order to extend the joints.
This description presents the manner in which the procedure is performed on the left side of the patient. Similarly, the same steps are followed on the right side. In the standard version, the procedure is first performed on the left side and then on the right side.
