Kinemetics Flashcards
(26 cards)
______ is a study of combined art and science of human movement.
kinesology
What are biomechanics?
application of physics to the human body
Clinical Kinesiology refers to?
applying the study of kinesiology to the health care environment,
What is a force that produce or resists movement?
kinetics.
Kinematics are?
Types of movement without thinking about the forces acting on the surface.
What motion occurs motion in a straight line?
Linear motion.
An example of curvilinear motion is when the center of mass changes as we walk. True or False?
True.
What is the movement of the bone segments that make up a joint called?
Osteokinematics.
Arthrokinematics is a movement that occurs when?
Within and between joint surfaces.
The sagittal plane divides the body into and what movements occur in this plane?
Divides the body into left and right with movements of ABDuction and ADDuction.
What plane divides the body into anterior and posterior?
Frontal/ coronal.
Flexion and extension occur in this plane.
Which plane allows lateral trunk flexion and what does it divide the body into?
The transverse plane divides the body into inferior and superior segments.
Does ROM occur in artherokinematics or osteokinematics?
Osteokinematics.
What is a type of motion that occurs around an axis?
Rotary motion.
It is the most common motion in the body.
Name an example and how many degrees of freedom a triaxial axis have. Biaxial? Uniaxial?
Triaxial has 3 degrees of freedom (occurs in 3 planes) and an example is the hip (ball and socket joint)
Biaxial has 2 degrees of freedom and an example is Metacarpal Pharyngeal joints (saddle)
Uniaxial joints only have one degree of freedom and an example would be the elbow. (hinge joint)
What end feel feels hard and why?
A hard end feel because it’s bone hitting bone.
What is a soft end feel?
Muscle hitting muscle before the end range, limiting full ROM.
What creates a firm end feel?
Ligaments refraining motions that could tear a joint.
The distal segment is fixed to a surface during _______ kinematic chain.
Give an exercise example of this chain.
Closed kinematic chain.
Ex. squats. (feet are fixed to the floor)
In an open kinematic chain, what is the distal segment capable of?Name an example exercise.
Free movement. not fixed to a surface.
Ex. bicep curls (even though hand is holding the weight, it is not fixed to a surface to remain stable).
What is the type of joint responsible for providing stability?
Synarthrosis.
Ex. sutures in skull.
Ampiarthrosis joints provide?
Stability and some motion for shock absorption.
Ex. vertebrae.
What is a hip joint an example of? (joint wise)
Dianthrosis. (synovial) most common in the body.
What are the four basic movements of arthrokinematic joints?
Rolling, sliding, spinning, compression.
