Examples of the use of resistance in patient treatment:
— Resist muscle contractions in a sound limb to produce contraction of the muscles in the immobilized contralateral limb.
— Resist hip flexion to cause contraction of the trunk flexor muscles (O Fig. 2.2).
— Resist supination of the forearm to facilitate contraction of the external rotators of that shoulder.
— Resist hip flexion with adduction and external rotation to facilitate the ipsilateral dorsiflexor muscles to contract with inversion (O Fig. 2.3).
— Resist neck flexion to stimulate trunk and hip flexion. Resist neck extension to stimulate trunk and hip extension.

If you weaken the center of any freestanding structure it becomes unstable. Eventually, everyday wear-and-tear takes its toll, causing the structure to buckle under pressure. This is exactly what happens when the core muscles are weak – it compromises your body’s ability to support the frame properly. In recent years, there has been a lot of buzz about the importance of a strong core – and there is a valid reason for this. The core is where all of the powerful movements in the body originate – so it can essentially be thought of as your “center of power.”
