normal extensibility of all soft tissues that allow for full range of motion of a joint.
capability to be elongated or stretched
dynamic range of motion
combination of flexibility and the nervous system's ability to control this range of motion efficiently
ability of the neuromuscular system to allow agonists, antagonists, and stabilizers to work synergistically to produce, reduce, and dynamically stabilze the entire kinetic chain in all three planes of motion.
dynamic functional flexibility:
multiplanar soft tissue extensibility w/ optimal neuromuscular efficiency throughout the full range of motion
postural distortion patterns:
predictable patterns of muscle imbalances
tendency of the body to seek the path of least resistance during functional movement patterns.
- alteration of muscle length surrounding a joint
- causes: postural stress, emotional duress, repetitive movement, cummaltive trauma, poor technique, lack of core strength, lack of neuromuscular control
altered reciprocal inhibition:
concept of muscle inhibition, caused by tight agonist, which inhibits its functional antagonist.
neuromuscular phenomenon that occurs when inapporpriate muscles take over the function of a weak or inhibted prime mover
the motions of joints in the body
altered forces at the join taht results in abnormal muscular activity and impaired neuromuscular communicaation at the joint.
process when neural impulses that sense the tension is greater than the impulses that cause muscles to contract providing an inhibitory effect to the muscle spindles.
consistently repeating the same pattern of motion, which may place abnormal stresses on the body.
states that soft tissue models along the lines of stress
progression of flexibility:
- corrective: foam roll, static stretching
- active flexibility: foam roll, supine straight leg raise
- functional: dynamic stretching (side lunge), foam roll
passively taking a muscle to the point of tension and holding the stretch for a min of 20 seconds.
active isolated stretch
using agonists and syngergists to dynamically move the joint into a range of motion
