Functional gains can be achieved through ANSWER: compensation, restoration or more normal movement capabilities, or a combination of the two. ASIA ____ and _____ are absent of voluntary motor function below the lesion ANSWER: A or B ASIA ____ and ____ have preserved voluntary motor function after injury ANSWER: C and D Three compensatory movement strategies are available to enable a person with complete spinal cord injury to make the most of what musculature remains functional: ANSWER: Muscle substitution momentum head-hip relationship Muscle substitution Deeagles - Stuvia US ANSWER: in one method of substitution, agonistic musculature compensates for strength deficits. For example, the tensor fasica lata can substitute for a weak or absent gluteus medius in hip abd. agonists muscles ANSWER: Produces action; prime mover In addition to substitution by agonists, there are three ways in which a muscle can be used to substitue. ANSWER: -muscle action can be combined with the effects of gravity -tension in passive structures -fixation of the distal extremity to effect a desired motion Substitution using gravity ANSWER: musculature can be used to reposition a part in such a way that gravity will effect the desired motion. For example, shoulder motion can be used to pronate the forearm. When a person is sitting upright, shoulder abd and internal rotation can move the forearm to a position in which the palm faces downward slightly. Gravity will pronate the forearm. Substitution using tension in passive structures ANSWER: The tenodesis grasp is an example. The extensor carpi radialis longus and brevis are used to extend the wrist. The resulting increase in tension in the flexor
