Quiz 1 Flashcards
What are the 5 principles of movement science?
Tissue source Pathomechanics (abnormal body mechanics) Tissue Stretch Impairments (what is causing the pathomechanical movement) Education
Examples of Tissue stress: Disc? Joints? Muscle?
Disc- Compression
Joints- shearing
Muscle- tensile
_ is the study of the response of the biological systems to mechanical forces.
Biomechanics
What is the equation for force? Common example that affects movement?
Force = Mass X acceleration
Common example: ground reaction force
_ is a physical force exerted on a body part
STRESS
_ _ are forces acting on a body part that are attempting to stretch the body part.
TENSILE STRESS are forces . . .
When tissues/ muscles are in a _ position the tensile strength is increased.
When tissues/ muscles are in a LENGTHENED position the tensile . . .
_ _ is a force acting on a body parallel to that body part.
SHEARING FORCE is a force acting . . .
A _ _ is a force acting on the body that is perpendicular to the body part.
A COMPRESSIVE FORCE is a force . . .
Equation for pressure?
Pressure = force/ area
Equation for power? Work?
Power= work/ time
Work = force X distance
_ occurs due to cumulative stresses, due to _ movements, over a _ period of _.
PAIN occurs due to cumulative stresses, due to REPETITIVE movements, over a PROLONGED period of TIME.
_ _ helps reduce patient anxiety and stress.
PATIENT EDUCATION
Compression of the patella into the femur occurs due to _ in the _ and _ _. Causes? Due to?
Compression occurs due to TIGHTNESS in the QUADS and PATELLAR TENDON.
Causes ANTERIOR KNEE PAIN
Due to QUAD DOMINANT STRATEGY
How can you help train patient to use a hip dominant versus quad dominant strategy with squats?
By restricting/ blocking movement of the knee so it cannot go past the toes
When the knee is allowed to move past the toes in a squat (quad dominant pattern) which joint sees the greatest increase in torque placed up on it?
Hips
The amount of torque placed on the knee _ with a hip strategy. With a quad dominant strategy?
Amount of torque placed on the knee DECREASES with a hip strategy.
INCREASES with a quad dominant strategy
What is the 3 things you should look at when observing posture?
1- Lumbar spine (sway back, flat back, lordosis, kyphosis)
2-Pelvis (posterior versus anterior tilt)
3- Plumb line between ear- shoulder- hip (should be aligned)
