Document Summary

Chapter 6: the upper extremity: the elbow, forearm, wrist and hand. It is active with all movements when supinated. Brachioradialis: active in quick movements, active with resisted elbow flexion. Pronator teres: pronater and elbow flexor against resistance. Supinator: palpation of the radial head: see figure. Hip flexion with knee straight vs knee flexed. Passive insufficiency length of a muscle results in an inability of the multi-joint muscle to allow full rom at both, or all, joints simultaneously. Limits agonist from moving the joints through full range. Ex hamstrings may be passive insufficient when person actively and simultaneously flexes hip and extends knee while standing. Active insufficiency - the tension a muscle develops depends, in part, on its length. If the muscle is significantly shortened or lengthened, it will not be able to develop as much tension as it will near mid- length and is said to be actively insufficient. Ex: try to flex fingers when wrist is in full flexion.
