Ch 7 Flashcards
Relative flexibility
The tendency of the body to seek the path of least resistance during functional movement patterns
Altered reciprocal inhibition
The concept of muscle inhibition, caused by a tight agonist, which inhibits its functional antagonist
Dynamic stretch
The active extension of a muscle, using force production and momentum, to move the joint through the full available range of motion
Postural distortion patterns
Predictable patterns of muscle imbalances
Active-isolated stretch
The process of using agonists and synergists to dynamically move the joint into a range of motion
Autogenic inhibition
The process by which neural impulses that sense tension are greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles
Dynamic range of motion
The combination of flexibility and the nervous system’s ability to control this range of motion efficiently
Arthrokinetic dysfunction
Altered forces at the joint that result in abnormal muscular activity and impaired neuromuscular communication at the joint
Synergistic dominance
The neuromuscular phenomenon that occurs when inappropriate muscles take over the function of weak or inhibited prime mover
Static stretching
The process of passively taking a muscle to a point of tension and holding the stretch for a minimum of 30 seconds
Extensibility
Capability to be elongated or stretched
Davis’s law
States that soft tissue models along the lines of stress
Arthrokinematics
The motions of joints in the body
Pattern overload
Consistently repeating the same pattern of motion, which may place a normal stress on the body
Muscle imbalance
Alteration of muscle length surrounding a joint
