Ability to move a joint through its complete rang of motion (ROM)
Capability to be elongated or stretched
- Combination of flexibility and nervous system's ability to control this ROM efficiently.
- Optimal control of movement through a joint's entire ROM
Ability of the nervous system to recruit correct muscle (antagonists, synergists, stabilizers) to produce force (concentrically), reduce force (eccentrically), and dynamically stabilize (isometrically) the body's structure in all 3 planes of motion.
Postural Distortion Patterns
Predictable patterns of muscle imbalances
The tendency of the body to seek the path of least resistance during functional movement patterns
Alteration of muscle length surrounding a given joint
The simultaneous relaxation of one muscle and the contraction of its antagonist
Altered Reciprocal Inhibition
Caused by a tight agonist muscle decreasing neural drive to its functional antagonist.
Neuromuscular phenomenon when synergists take over function for a weak inhibited prime mover.
The motions of joints in the body
Biomechanical and neuromuscular dysfunction leading to altered join motion
The process by which neural impulses that sense tension are greater than the impulses that cause the muscle to contract, providing an inhibitory effect to the muscle spindles.
Consistently repeating the same pattern of motion, which may places abnormal stresses on the body.
States that soft tissue models along the lines of stress
What are the 3 phases of flexibility?
What is Corrective flexibility's objective, and how is it gone about?
- Objective: Increase joint ROM, improve muscle imbalances, correct altered joint motion
- How: SMR and static stretching
What is Active flexibility's objective, and how is it gone about?
- Objective: Improve the extensibility of soft tissue and increase neuromuscular efficiency by using reciprocal inhibition
- How: SMR and active isolates stretching
What is Funtional flexibility's objective, and how is it gone about?
- Objective: increase flexibility with optimal neuromuscular control
- How: SMR and dynamic stretching
