Volcab Ch 7 Flashcards
Active Flexibility
The ability of agonists and synergists to move a limb through the full range of motion while their functional antagonist is being stretched.
Active-Isolated Stretch
The process of using agonists and synergists to dynamically move the joint into a range of motion.
Altered Reciprocal Inhibition
The concept of muscle inhibition, caused by a tight agonist, which inhibits its functional antagonist.
Arthrokinetic Dysfunction
- A biomechanical and neuromuscular dysfunction in which forces at the joint are altered, resulting in abnormal joint movement and proprioception. 2. Altered forces at the joint that result in abnormal muscular activity and impaired neuromuscular communication at the joint.
Arthrokinetic Inhibition
The neuromuscular phenomenon that occurs when a joint dysfunction inhibits the muscles that surround the joint.
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.
Corrective Flexibility
Designed to improve muscle imbalances and altered arthrokinematics.
Cumulative Injury Cycle
A cycle whereby an injury will induce inflammation, muscle spasm, adhesions, altered neuromuscular control, and muscle imbalances.
Davis?s Law
States that soft tissue models along the line of stress.
Dynamic Range of Motion
The combination of flexibility and the nervous system?s ability to control this range of motion efficiently.
Dynamic Stretching
- Uses the force production of a muscle and the body?s momentum to take a joint through the full available range of motion. 2. The active extension of a muscle, using force production and momentum, to move the joint through the full available range of motion.
Extensibility
Capability to be elongated or stretched.
Flexibility
The normal extensibility of all soft tissues that allows the full range of motion of a joint.
Flexibility Training
Physical training of the body that integrates various stretches in all three planes of motion to produce the maximum extensibility of tissues.
Functional Flexibility
Integrated, multiplanar, soft tissue extensibility with optimum neuromuscular control through the full range of motion.
Pattern Overload
- Repetitive physical activity that moves through the same patterns of motion, placing the same stresses on the body over time. 2. Consistently repeating the same pattern of motion, which may place abnormal stresses on the body.
Posterior Pelvic Tilt
A movement in which the pelvis rotates backward.
Postural Distortion Patterns
Predictable patterns of muscle imbalances.
Range of Motion
Refers to the range that the body or bodily segments move during an exercise.
Reciprocal Inhibition
The simultaneous relaxation of one muscle and the contraction of its antagonist to allow movement to take place.
Relative Flexibility
The tendency of the body to seek the path of least resistance during functional movement patterns.
Self-Myofascial Release
Another form of flexibility that focuses on the fascial system in the body.
Static Stretching
The process of passively taking a muscle to the point of tension and holding the stretch for a minimum of 30 seconds.
Synergistic Dominance
- When synergists take over function for a weak or inhibited prime mover. 2. The neuromuscular phenomenon that occurs when inappropriate muscles take over the function of a weak or inhibited prime mover.
Upper-Extremity Postural Distortion
An individual who exhibits a forward head, rounded shoulder posture.
