Trainer position
Stand on the client's left (the side shown in the 3D) with your feet apart front to back, at a height that suits the table. Move by shifting your body weight rather than holding with the arms alone.
Contact and support
Support the heel from underneath with the palm and place the other hand on the front of the knee.
Hand placement in 3D: heel, front of the knee
Stabilisation
The other leg rests on the table. If it lifts, reduce the range.
Compensation
Bending of the knee, posterior pelvic tilt, lifting of the other leg.
Easier option
Reduce the range and let the weight of the leg or arm rest on a cushion or the table. Go back to checking a pain-free starting position.
Cues and consent
Tell the client where you will touch and which way you will move, and say, 'Tell me straight away if you feel any pain or discomfort.' Confirm consent before touching and before moving.
Stop criteria
Return to the starting position immediately if the client reports sharp pain, numbness, weakness, a pinching feeling in the joint, dizziness, shortness of breath or anxiety, or asks to stop.
