Muscles
Push-ups are the best way to strengthen what muscle?
Pectoralis Major
This law explains why bone spurs and bony landmarks grow.
Wolf's Law
This type of contaction decelerates the body
Eccentric Contraction
True or False
When your client brings their arm back down after grabbing a can of soup off a high shelf, their shoulder flexors are eccentrically contracting
True
When two different muscles contract at the same time to produce a rotating action, it is called what?
Forced Couple
This muscle concentrically contracts to produce shoulder flexion.
Anterior Deltoid
Pec Major (upper fibers)
Biceps Brachii
This law is associated with the term "Reciprocal Inhibition"
Sherrington's Law
Flexion/Extension and Horizontal Adduction/Abduction
Flexion/Extension and Internal/External Rotation
This is the best type of exercise to give to clients after they have had surgery.
Isometric Contraction Exercises
This type of muscle helps agonists perform their main action.
Synergist
When lowering the shoulder down to the body from abduction, what muscle is eccentrically contracting?
Deltoid (All fibers and Middle specifically)
Supraspinatus
This law can be attributed to "Muscle Memory"
Law of Facilitation
This action is produced when Upper Traps and Lower Traps contract at the same time.
Upward rotation of the scapula
I am trying to strengthen a multiarticular muscle by concentrically contracting at more than one joint at the same time. What is happening to me?
Active Insufficiency
This muscle is not active when its opposite is contracting. What am I?
Antagonist muscle
During a push-up, I am concentrically contracting during the upward phase of this exercise. What muscle am I?
Triceps Bracii at the elbow
What law can explain why we use Superficial-Deep-Superficial as a principle of massage, why getting a bruise can feel deeper than the skin, and can make us weaker when we have superficial injuries.
Hilton's Law
When internal shoulder rotators and adductors are short and tight, what actions would be restricted?
External rotation and abduction
Throwing a baseball would produce which muscles to control (eccentrically contract) internal rotation once the ball has been released
Teres minor, posterior deltoid, infraspinatus
These muscles are small and very close to their joints. The actions they produce are not great but they are very important. What are these muscles called?
Stabilizers
You client has pain in the back of their shoulder but the pain goes away when they are doing their push-up exercises for the day. What muscle is inhibited, causing the pain to go away?
Upper Traps
Your client has been an office worker for 25 years and is now retiring. They can't wait to start regular bi-monthly sessions with you and talk often about their back and neck pain. Your client is older than 50 and when they come in for their first treatment you can't help but notice obvious changes in the posture of their upper back, neck, and shoulders. What law is partly responsible for the change in their posture?
Davis' Law
When you cradle a phone to your ear, your shoulder is elevated, head rotated and laterally flexed, scapula protracted. What is happening to Lower Traps in this position?
Passive Stretch
"Resist with about 25% of your strength as I push up on your arm. Let me overpower you."
This would produce what kind of contraction on the shoulder adductors?
Eccentric Contraction
I live in muscle bellies and detect when there is too much length happening too quickly. When I sense danger I turn the muscle off. What am I?
Muscle Spindles
