__________ is the ability to move a joint through its complete range of motion. The normal extensibility of all soft tissues that allow full range of motion (ROM).
flexibility
_________ is the capability to be elongated or stretched.
Extensibility
_________ is the combination of flexibility and the nervous system’s ability to control this range of motion efficiently.
Dynamic Range of Motion
__________ is the ability of the nervous system to properly recruit the correct muscles (agonists, antagonists, synergists, and stabilizers) to produce force(concentrically), reduce force (eccentrically), and dynamically stabilize (isometrically) the body’s structure in all three planes of motion.
Neuromuscular Efficiency
Patterns of dysfunction referred to as _________, which can lead to decreased neuromuscular efficiency and tissue overload.
Postural Distortion Patterns
Muscle Imbalances
Poor Posture
Improper movement
Injury
_________ occurs when a person has tightness in a muscle that leads them to not be able to
perform an exercise correctly. The body seeking the path of least resistance
Relative Flexibility
_____________ are alterations in lengths of muscles surrounding a given joint, in which some are overactive (forcing compensation to occure) an others may be underactive (allowing for the compensation to occur)
Muscle Imbalance
Factors Causing Muscle Imbalances
- Postural stress
- Emotional distress
- Repetitive movements
- Cumulative trauma
- Poor training technique
- Lack of core strength
- Lack of neuromuscular control
________ is the simultaneous relaxation of one muscle and the contraction of its antagonist to allow movement to take place.
Reciprocal Inhibition
Muscle inhibition, caused by a tight agonist, which
then inhibits its antagonist
Altered Reciprocal Inhibition
Example, a tight psoas (hip flexor) would decrease neural drive of the gluteus maximus (hip extensor).
Inappropriate muscles take over the function of a
weak or inhibited prime mover
Synergistic Dominance
__________ is the motions of the joints in the body
Arthrokinematics
__________ is the motions of the joints in the body
Arthrokinematics
Altered forces at the joint that result in abnormal
muscular activity and impaired neuromuscular
communication at the joint
Arthrokinetic Dysfunction
_____________ is the phenomenon of the GTO turning off the muscle spindle. Main principle used in: Self-myofascial release and Static stretching. Neural impulses that sense tension are greater than the impulses that cause muslces to contract, providing a inhibitory effect to the muscle spindle.
Autogenic Inhibition
