Chapter 7 Flashcards
States that soft tissue models along the lines of stress
Davis’s law
Tendency of the body to seek the path of least resistance during functional mvmt patterns
Relative flexibility (leads to muscle imbalances)
Alteration of a muscle surrounding a joint
Muscle imbalance
Concept of muscle inhibition caused by a tight agonist which inhibits its fxnl antagonist
(Tight psoas decrease the neural drive to the glutes)
Altered reciprocal inhibition
Inappropriate muscles take over the function of a weak inhibited prime mover. Psoas tight, decrease glute…hamstring will take over
Synergistic dominance
Simultaneous contraction of one muscle and relaxation of its antagonist
Reciprocal inhibition
Difference b/w muscle spindles and GTO
Muscle spindles detect change in length, cause contract
GTO detect change in tension, cause relaxation
prolonged Golgi tendon stimulation provides inhibitory action to the muscle spindles, this is called
Autogenic Inhibition
Normal extensibility of all soft tissues that allow the full ROM of a joint
Flexibility
Three types of flexibility in the Flexibility Continuum. Name stretches performed in each and variables
Corrective- SMR; 30 seconds. Static; 1-3 sets 1 rep 30 sec
Active- SMR; 30 second; active isolated stretch; 1-2 sets, hold 1-2 seconds 5-10 reps
Functional -SMR; 30 seconds Dynamic 1 set 10-15 reps, 3-10 exercises
Flexibility that is designed to correct and improve muscle imbalances, done in Phase 1
Corrective
Flexibility that takes muscle to new length and uses it in a full ROM
Active
Establishes flexibility at higher and more realistic speeds
Functional
What occurs with SMR
Autogenic inhibition
Which type of flexibility uses reciprocal inhibition
dynamic
Name 3 dynamic stretches
Prisoner squats, tube walking, SL squats
Explain the cumulative injury cycle
Tissue trauma Inflammation Muscle spasms Adhesions Altered neuromuscular control Muscle imbalances
How can you get out of the cumulative injury cycle
Incorporate an intergrated flexibility training program
Which flexibility technique uses autogenic inhibition
Corrective
Which type of flexibility is better before exercise
Active and functional
Stretch the ______ muscles. Strengthen the ______muscles
Overactive, tight
Underactive, weak
How would u regress and progress an SMR stretch
Regress: softer roller or towel
Progress: Different size roller, lacrosse ball
Progress a SMR TFL stretch
Top leg over bottom or diff roller
Capability of being elongated or stretched
extensibility
Combo nation of flexibility and nervous systems ability to control ROM efficiently
Dynamic ROM
The ability of the nervous system to allow agonist, antagonist, synergists, and stabilizers to work together to produce, reduce, and dynamically stabilize the entire kinetic chain in all 3 planes
Neuromuscular efficiency
Predictable patterns of muscle flexibility
Postural distortion patterns
Motion of joints
Arthrokinematics
Occurs when joint is not working properly
Arthrokinetic dysfunction
Taking muscle to the point of tension and holding 30 sec
Static stretching
stretch that uses agonists and synergists to dynamically move the joint into a ROM
Active stretching
Active extension of a muscle using force production and momentum to move a joint through full ROM
Dynamic stretching
Name two mechanoreceptors
GTO and muscle spindles
Purpose of corrective flexibility
Increase joint ROM
Improve muscle imbalances
Correct altered joint motion
Purpose of active flexibility
improve extensibility of soft tissue and increase neuromuscular efficient by using reciprocal inhibition
Purpose of functional flexibilty
Increase multiplanar soft tissue extensibility with optimal neuromuscular control , through the full range of motion
