Client is supine with the knee flexed approx. 70 deg. The heel is lifted of the ground. The base joint of the big toe and 5. toe should be the primary contact area. Fiksate in the front part of the knee with one hand and grab around the lower part of the calf with the other hand. Ask the client to apply pressure into the ground through the base joint of the big toe and 5. toe, and then apply pressure towards extension of the knee in a horizontal line along the ground (trying to slide the foot).

Note: If the client is incapable of lifting the heel off the ground due to lack of plantar flexion, the knee should be bend slighty more until heel lift is possible.
