The application of Aiki in the techniques demonstrated by Katsuyuki Kondo is analysed below.

At a time of 0.40 Uke attacks with shomenuchi after grabbing Tori. Tori induces Uke to apply Aiki by applying pressure with his thumb to a nerve above the elbow as he blocks the shomenuchi at the beginning of the forward movement. To minimise the pain at the pressure point, Uke reverses the muscle torque about the knee joint of his rear leg causing him to become unbalanced to the rear by the contact reaction force due to the block.

At a time of 1.09 Tori extends his arms towards Uke as Uke steps forward to grab Tori's arms. At the moment that Uke closes his grip, Tori induces Uke to apply Aiki by withdrawing his arms. This action causes Uke to follow Tori's arms by reversing the muscle torque about the ankle joint of his front foot. Consequently, Uke is unbalanced to the front by his forward momentum. Aiki-Feint

The application of Aiki in the techniques demonstrated by Katsuyuki Kondo is analysed below.

At a time of 4.32 Tori extends his left arm towards Uke as Uke steps forward to grab Tori's left arm. At the moment that Uke closes his grip, Tori induces Uke to apply Aiki by withdrawing his arms. This action causes Uke to follow Tori's arms by reversing the muscle torque about the ankle joint of his front foot. Consequently, Uke is unbalanced to the front by his forward momentum. Aiki-Feint

At a time of 5.50 Uke steps forward to grab Tori's jacket. At the moment that Uke closes his grip, Tori induces Uke to apply Aiki by applying an upward atemi to Uke's upper body. This action causes Uke to reverse the muscle torque about the ankle joint of his front foot so as to minimise the impact of the atemi by rotating his hips forward to increase the height of his upper body. Consequently, Uke is unbalanced to the front by his forward momentum. Aiki-Feint
